What Is the CCC Code? A Complete Guide to Taiwan's 11-Digit Import Tariff Code
What Is the CCC Code?
The CCC Code (Standard Classification of Commodities of the Republic of China, 中華民國輸出入貨品分類號列) is the 11-digit classification number applied to goods imported into and exported from Taiwan. Taiwan did not invent it from scratch: the first 6 digits are taken directly from the international HS Code issued by the World Customs Organization (WCO), and only from the 7th digit onward come the subdivisions Taiwan adds for taxation and trade-management purposes. When filing a declaration you must choose the code that matches the goods' material, use, composition and specification; customs then relies on that code to determine customs duty, business tax, commodity tax and import requirements.
Think of the CCC Code as the “tariff coordinates” of a product in Taiwan: the first 6 digits are shared with the whole world, the last 5 are understood only in Taiwan. Similar products may share a code, and getting the classification right affects the duty rate, inspection requirements and import restrictions.

The CCC Code is Taiwan's own 11-digit import/export commodity classification number: the first 6 digits follow the international HS Code set by the World Customs Organization (WCO), while the remaining 5 are defined by Taiwan. It determines the duty rate, the import regulations and the trade-statistics classification. HowBridge's on-site tariff database currently holds about 12,700 CCC 11-digit lines; you can look a line up by Chinese product name — and see all three tariff columns — without logging in.

| Which agency governs which digits | Digits 1–6 = the WCO international HS Code (identical worldwide); digits 7–8, the tariff subdivision, are governed by the Customs Administration, Ministry of Finance and used to levy customs duty; digits 9–10, the statistical subdivision, are governed by the International Trade Administration, Ministry of Economic Affairs and used for import/export control and trade statistics; digit 11 is a check digit generated automatically from the first 10. |
| Column 1 duty rates, actually looked up | Smartphones 8517.13.00.00-5 are 0%; leather handbags 4202.21.00.00-3 are 6.6%; running shoes with textile uppers 6404.11.00.50-6 are 7.5%; fresh grape wine in containers of 2 litres or less 2204.21.00.00-5 is 10% (Column 1 = the column for WTO members and countries granting Taiwan reciprocal treatment). |
| Taxes beyond customs duty | Every import also carries 5% business tax on top of customs duty; tobacco and alcohol, and some vehicles and appliances, additionally attract Tobacco and Alcohol Tax or Commodity Tax — so “0% duty” does not mean tax-free. |

CCC vs. HS Code: The Difference
Many people confuse the CCC Code with the HS Code. Here is how the two actually relate:
| Item | HS Code | CCC Code |
|---|---|---|
| Full name | Harmonized System Harmonized Commodity Description and Coding System | Standard Classification of Commodities of the R.O.C. (中華民國輸出入貨品分類號列) |
| Issuing body | World Customs Organization (WCO) (an independent intergovernmental organization, not an agency of the United Nations) | First 8 digits: Customs Administration, Ministry of Finance Digits 9-10: International Trade Administration, Ministry of Economic Affairs |
| Length | 6 digits (identical worldwide) | 11 digits (= 6 HS digits + 5 Taiwan digits) |
| Purpose | A common language for international trade; the shared basis for national tariff schedules and trade statistics | Taiwan import and export declarations, duty assessment and import/export controls |
| Relationship | The first 6 digits of the CCC Code = the HS Code | CCC = HS + 5 Taiwan-specific digits |
📌 In short: the first 6 digits of the CCC Code are the international HS Code, and that is no coincidence — Article 3 of the HS Convention requires contracting parties to use all of the HS headings and subheadings together with their codes, without addition or modification; further subdivision is permitted only beyond the 6th digit. That is why the first 6 digits of the tariff schedules of 212 economies worldwide (163 of them contracting parties to the Convention) match one another, covering more than 98% of international trade. From the 7th digit each goes its own way, so Taiwan's 11-digit code cannot simply be used in another country, and another country's code cannot simply be treated as a Taiwanese CCC Code. The United States, for example, uses the HTS for imports and Schedule B for export statistics — neither of which is Taiwan's CCC Code.
Digit counts by economy: why are the first 6 digits the same everywhere?
The HS Code is issued by the World Customs Organization (WCO) — an independent intergovernmental organization founded in 1952 (originally named the Customs Co-operation Council, CCC), not a subordinate body of the United Nations. Every national tariff schedule is built on the same HS framework: the first 6 digits are identical worldwide, and that is what makes cross-border trade and comparable statistics possible. From the 7th digit onward each country classifies according to its own industrial structure, tax policy and administrative needs, so the total number of digits differs. Taiwan uses 11 digits, Japan 9:
| Economy | Digits | Name of the system | How the digits from the 7th onward are split |
|---|---|---|---|
| 🇹🇼 Taiwan | 11 | CCC Code Standard Classification of Commodities of the R.O.C. | HS 6 + tariff number 2 (Division) + statistical number 2 (Item) + check digit 1 |
| 🇯🇵 Japan | 9 | Import/export statistical commodity code (輸出入統計品目番号) (Tariff Schedule, 実行関税率表) | HS 6 + 3 domestic digits; the import and export subdivisions are not necessarily the same |
| 🇰🇷 South Korea | 10 | HSK 관세·통계통합품목분류표 (Integrated Tariff and Statistics Nomenclature) | HS 6 + 4 domestic digits |
| 🇨🇳 Mainland China | 10 | Commodity code (商品編號) | HS 6 + 2 tariff and statistical digits (together making up the first 8) + 2 regulatory add-on digits |
| 🇺🇸 United States | 10 | Imports: HTSUS Export statistics: Schedule B | HS 6 + 4; imports and exports use two different schedules |
| 🇪🇺 European Union | 8 / 10 | CN Combined Nomenclature TARIC integrated tariff database | Digits 7-8 are the CN subdivision (declarations commonly use 8 digits); adding digits 9-10 gives the TARIC code |
| 🇭🇰 Hong Kong | 8 | HKHS Hong Kong Harmonized System | HS 6 + digits 7-8 as Hong Kong's own subdivision |
| 🌏 ASEAN | 8 | AHTN ASEAN Harmonised Tariff Nomenclature | Vietnam, Thailand, Indonesia, Singapore and others share the same 8-digit base; some member states extend it further |
The HS Convention requires contracting parties to be consistent only down to the 6th digit; beyond that each country adds its own digits and there is no correspondence between them. So entering a Japanese 9-digit code straight onto a Taiwanese declaration is guaranteed to be wrong, and the same is true in reverse. When comparing tariff schedules across countries, the only part that can safely be matched is the first 6 digits; everything after that must be reclassified in the destination country's own schedule. It is also why the 10-digit “commodity code” supplied by a seller in mainland China cannot be used as a Taiwanese CCC Code — only the first 6 digits line up.
Anatomy of the 11-digit CCC Code: Chapter, Heading, Subheading, Division, Item
Digits 3-4: 04 = Heading|the first 4 digits, 3304, cover beauty and cosmetic preparations
Digits 5-6: 99 = Subheading|the first 6 digits, 330499 — international HS harmonization ends here, and this much is the same worldwide
Digits 7-8: 10 = Division|Taiwan's customs tariff number, administered by the Customs Administration, Ministry of Finance, and used to levy customs duty
Digits 9-10: 91 = Item|administered by the International Trade Administration, Ministry of Economic Affairs, for import/export control and trade statistics
Digit 11: 7 = check digit|generated automatically from the first 10 digits and used to verify that the code has not been mistyped
CCC Code Examples for 8 Common Products
| Product (tariff description) | CCC Code | Column I duty rate |
|---|---|---|
| Smartphones (iPhone and the like) | 8517.13.00.00-5 | 0% |
| Sheet masks (classified as “other beauty or make-up preparations and preparations for the care of the skin”) | 3304.99.90.91-0 | 0% |
| Handbags with an outer surface of leather or composition leather | 4202.21.00.00-3 | 6.6% |
| Running shoes with rubber/plastic outer soles and textile uppers | 6404.11.00.50-6 | 7.5% |
| Roasted coffee, not decaffeinated | 0901.21.00.00-5 | 0% |
| Other wine of fresh grapes, in containers of 2 litres or less | 2204.21.00.00-5 | 10% |
| Perfumes and toilet waters | 3303.00.00.00-8 | 0% |
| Video game consoles used with a television receiver (software not included) | 9504.50.00.10-0 | 0% |
The codes and rates above come from the tariff database of the Customs Administration, Ministry of Finance (the version mirrored on this site, verified 2026-08-06); the rates shown are those of Column I (applicable to WTO members and countries granting reciprocal treatment). Three reminders: ① the “Product” column gives the tariff description, not a marketing name — classification follows material, composition and use, not the brand; ② products of the same kind often fall under different codes because of their material (shoes with leather uppers and shoes with textile uppers sit in different chapters and carry different rates); ③ duty is not necessarily the only charge — wine, for instance, also attracts tobacco and alcohol tax as well as business tax. The classification and rate finally applied are those determined by customs.
How to Look Up a CCC Code and Its Tariff Rate
At https://howbridge.cn/search, type a product term such as "face mask" or "coffee beans" to instantly match the CCC Code, tariff rate, licensing requirements, and AI-powered suggestions.
On the Customs Administration's "Import/Export Tariff and Commodity Classification Search" at https://portal.sw.nat.gov.tw/APGA/GA03, enter a CCC number or product name. It is the most authoritative source but more cumbersome to use.
Every CCC code carries three columns of duty rates, and under General Rule 2 of the 《Customs Import Tariff》 the applicable column is determined by the country of origin of the goods:
① Column I—— applies to WTO members and to countries/territories granting Taiwan reciprocal treatment; most imported goods fall under this column.
② Column II—— applies to specified goods from countries/territories that have signed a free trade agreement or an economic cooperation agreement with Taiwan, and to specified goods from certain least-developed and developing countries; this is the preferential column (commonly 0%). It currently covers Panama, Guatemala, Honduras, New Zealand, Singapore, Paraguay, Eswatini, Belize and the Marshall Islands, as well as goods on the ECFA Early Harvest List.
③ Column III—— where neither of the first two applies; the highest rates (goods at 5% under Column I may be 10% under Column III).
🔑 Two things to remember: where Column I and Column II could both apply, the lower rate is the one that applies; and what decides the column is the country of origin rather than where the seller is — buy online from the United States but find the goods marked as made in mainland China, and mainland China's treatment is what applies.
Every CCC line carries three tariff columns, and under General Rule 2 of the Customs Import Tariff the applicable column is decided by the country of origin of the goods:
① Column 1 — applies to WTO members and to countries/territories that grant Taiwan reciprocal treatment; most imported goods fall in this column.
② Column 2 — applies to specified goods from countries/territories that have signed a free trade agreement or economic cooperation agreement with Taiwan, and to specified goods from certain least-developed and developing countries; this is the preferential column (commonly 0%). It currently covers Panama, Guatemala, Honduras, New Zealand, Singapore, Paraguay, Eswatini, Belize and the Marshall Islands, plus goods on the ECFA Early Harvest List.
③ Column 3 — for goods that neither of the first two columns covers; the highest rates (a line at 5% in Column 1 may be 10% in Column 3).
🔑 Two things to remember: where both Column 1 and Column 2 could apply, the lower rate is used; and the column is decided by the country of origin, not by where the seller sits — buy from a US website but the goods are marked as made in mainland China, and mainland China's treatment is what applies.
Which tariff misclassifications has Customs flagged recently? 3 cases from Aug–Oct 2026
In one sentence: in all three cases the importer chose a parts or office-machine code based on which machine the item is fitted to or that it is used in an office, while Customs reclassified by material, construction or a dedicated machine heading under the chapter notes, the Interpretative Rules and the HS Explanatory Notes; in two cases the column-1 duty rate rose from 0% to 8.5% and 3%. The codes and reasons below come from the original Taipei Customs and Kaohsiung Customs press releases (accessed 2026-10-23).
| Product and release | Code declared by the importer | Code determined by Customs | Reasoning (key points of the press release) |
|---|---|---|---|
| Graphene thermal pads Taipei Customs 2026-10-08 | 8473.30.00.00-6 "parts and accessories of the machines of heading 8471", or 3801.90.00.00-6 "other preparations based on graphite or other carbon" | 6815.19.00.00-2 "other non-electrical articles of graphite or other carbon" (heading 6815) | Composite of graphene with metal or silicone, cut to a specific shape with release adhesive, used for heat dissipation; under the explanatory note to heading 3801, artificial graphite that has been worked or made into finished articles and is used for non-electrical purposes generally falls in heading 6815; Note 1(a) to Chapter 84 excludes Chapter 68 goods, so being fitted inside a server does not make it a part |
| Test-machine hose (HOSE) Kaohsiung Customs 2026-09-16 | 9030.90.10 "parts and accessories of instruments for measuring or checking semiconductor wafers or devices", column 1 FREE | 4009.41.90 "other tubes of vulcanised rubber, without fittings, reinforced or otherwise combined with other materials", column 1 8.5% | Made of rubber, without fittings, covered with nylon mesh and a spring; Note 1(a) to Chapter 90 excludes "articles of vulcanised rubber for use in machines, appliances or for other industrial uses"; supported by the HS Explanatory Note to heading 4009 (tubes may be covered with fabric and may incorporate metal spiral wire) |
| Paper cutter with protractor Kaohsiung Customs 2026-08-31 | 8472.90.90 "other office machines of heading 8472", column 1 0% | 8441.10.00 "cutting machines" (paper cutters), column 1 3% | Has a cutting base, guide rails, a slider containing a blade, a movable protractor and a transparent press ruler; operated by hand for straight cuts, so it is a dedicated paper-cutting machine; under General Interpretative Rules 1 and 6 and the HS Explanatory Note to heading 8441, "all machines for cutting", whether or not used in offices, fall in heading 8441, not in heading 8472, which covers office machines "not specified or included elsewhere" |
📎 Where the rates come from: the column-1 rates for the hose and the paper cutter are stated in the press releases; the graphene release gives no rate, so per HowBridge's on-site tariff database (synced with the Customs Administration, checked 2026-10-23) column 1 is 0% for 8473.30.00.00-6, 2.5% for 3801.90.00.00-6 and 10% for 6815.19.00.00-2. When the code changes, the import-regulation field may change too: in the same database 4009.41.90 carries C02 (some goods under this item are subject to BSMI import inspection) while 9030.90.10 does not; 8472.90.90 carries C02 while 8441.10.00 does not. Customs' determination and the competent authorities' announcements prevail.
① "Fitted inside a machine" does not mean "part": first check whether a chapter note excludes the goods (Note 1(a) to Chapter 84 excludes Chapter 68 goods; Note 1(a) to Chapter 90 excludes industrial articles of vulcanised rubber), and only then consider a parts code.
② Material and construction are the starting point: look at the thermal pad as a graphite/carbon article and at the hose as a reinforced vulcanised-rubber tube, not at the equipment it ends up in.
③ If a specific heading exists, do not use "other": heading 8472 only covers office machines "not specified or included elsewhere", and paper cutters have their own heading 8441.
④ All three releases advise: before importing, confirm material composition, manufacturing process and use, and if unsure apply to the Customs office at the port of import for an advance tariff classification ruling (see below).
What decides tariff classification? General Interpretative Rules 1–6 of the Customs Import Tariff
In one sentence: start from the heading texts and the section and chapter notes (Rule 1); only where the notes say nothing do Rules 2 to 5 apply, and comparisons between 6-digit subheadings follow Rule 6; General Provision 1 of the Customs Import Tariff also allows reference to the HS Explanatory Notes. The table summarises the original "Interpretative Rules" of the Customs Import Tariff (amended 28 January 2026) in the national law database:
| Rule | Key point | In this page's cases |
|---|---|---|
| 1 | Titles of sections, chapters and sub-chapters are for ease of reference only; classification is determined by the terms of the headings and any relative section or chapter notes, and only where these do not otherwise require, by the following rules | Customs expressly cited Rule 1 in the paper-cutter case; in the graphene and hose cases, chapter notes (Note 1(a) to Chapters 84 and 90) ruled out the parts codes |
| 2 | (a) Incomplete or unfinished articles that already have the essential character of the complete article at import are classified as the complete article; the same applies when unassembled or disassembled. (b) A reference to a material or substance includes mixtures or combinations of it; goods of more than one material are classified under Rule 3 | Often used for loose parts, kits and unassembled machines |
| 3 | Where goods are classifiable under two or more headings: (a) the heading with the most specific description prevails; (b) mixtures, composite goods and sets put up for retail sale are classified by the material or component giving their essential character; (c) otherwise, the heading that occurs last in numerical order | Often used for composite materials and combined products |
| 4 | Goods that cannot be classified under the rules above go to the heading for the goods to which they are most akin | Last resort for new types of goods |
| 5 | (a) Specially shaped cases suitable for long-term use, imported and normally sold with the articles, are classified with those articles (except where the case gives the whole its essential character); (b) packing materials and containers normally used for the goods are classified with them (except clearly reusable ones) | Camera bags, instrument cases, jewellery boxes, etc. |
| 6 | Classification in subheadings follows the terms of those subheadings and related subheading notes, comparing only subheadings at the same level; unless otherwise required, section and chapter notes also apply | Customs expressly cited Rule 6 in the paper-cutter case |
📌 General Provision 1 of the Customs Import Tariff: besides the section and chapter notes, heading texts and the Interpretative Rules, classification "may also refer to the Harmonized System Explanatory Notes compiled by the Customs Co-operation Council and other relevant documents". That is why Customs press releases often cite "the explanatory note to heading xxxx" — heading 4009 in the hose case, heading 3801 in the graphene case and heading 8441 in the paper-cutter case.
Not sure about the code? Advance tariff classification ruling (Customs Act Article 21)
In one sentence: before the goods are imported, the taxpayer or its agent may ask Customs to review the tariff code in advance and Customs replies in writing; if the goods actually imported are the same as those reviewed, Customs must apply the code given in the ruling. All three press releases end by recommending this route.
① Effect: if the goods actually imported are the same as the goods in the ruling, Customs must classify them under the ruling code, unless the applicant supplied wrong or false information that affected the result. When clearance is by document review or physical examination, a copy of the reply letter must be attached (Article 10 of the Regulations Governing the Implementation of Advance Tariff Classification Ruling on Imported Goods).
② If Customs changes the ruling: it must give reasons in a written notice; an applicant who proves that a contract has been concluded and trade is under way, and that a loss would result, may ask to keep using the original ruling for up to 90 days; where the new code involves import regulations, the regulations in force at import apply (Customs Act Article 21, paragraph 2).
③ If you disagree with the ruling: before import you may apply to the Customs Administration, Ministry of Finance, for reconsideration (paragraph 3 of the same article); the Administration notifies the result within 30 days from the day after receiving the application, extendable once by up to 30 days; if you still disagree, you must wait until the goods are imported and the port Customs has determined the code, then use the administrative remedies (Article 8 of the Regulations).
④ When no ruling is given: documents not supplemented in time or incomplete, hypothetical goods or goods still being designed, identical or similar goods already being handled under Article 13, Article 17 paragraph 5 or Article 18 of the Customs Act or in administrative remedy proceedings over a tariff dispute, waste, and the like (Article 6 of the Regulations).
⑤ For application documents and reply deadlines, see FAQ Q7 below.
🔍 Check what others have already asked: the Customs Administration publishes ruling cases on the government open data platform ("Advance Tariff Classification Ruling Cases") (fields include declared description, material composition, function and use, the code determined and the classification reasons), and they can also be searched in the Tariff Classification Inquiry System. ⚠️ A ruling settles the code; once the code is fixed, its import regulations (such as C02 or MW0) must still be met separately, and import regulations are those set by the International Trade Administration, Ministry of Economic Affairs (Article 3, paragraph 2 of the Regulations).
What happens if the tariff code is wrong? Back duty, fines and input VAT on company goods
In one sentence: if only the code is wrong, Customs reclassifies and collects the difference; misdeclaring the description, specification and the like can lead to a fine of up to five times the duty evaded or confiscation; and for company goods, if the declaration does not match the actual transactions, the input VAT may also be disallowed.
| Situation | Possible consequence | Legal basis (national law database) |
|---|---|---|
| Description and specification declared truthfully, only the code is wrong | Customs reclassifies and assesses duty at the correct rate (how the three press releases describe it; none mentions a fine). For goods released on a duty-first basis, Customs must notify any duty to be paid or refunded within 6 months from the day after release (except where a post-clearance audit has been notified); short-levied duty may be recovered within 1 year, with interest, payable within 14 days after the notice is served, and late payment incurs a surcharge of 0.05% per day | Customs Act Article 18 paragraph 1, Article 65 |
| Misdeclaring the name, quantity, weight, quality, value or specification of the goods, or submitting false invoices or documents | Depending on the seriousness, a fine of up to five times the import duty evaded, or confiscation of the goods with or without a fine; where import controls are evaded, penalties under Article 36 paragraphs 1 and 3 apply | Customs Anti-Smuggling Act Article 37 paragraphs 1 and 3 |
| You discover your own declaration error | If you apply for a correction before Customs, the tax authority or another assisting enforcement agency receives a report or starts an investigation, the correction is approved and the pre-release or post-release conditions are met, no penalty is imposed within the scope of the correction; back duty must be paid with daily interest | Customs Anti-Smuggling Act Article 45-3; for amending the declaration see also Customs Act Article 17 paragraphs 5 and 6 |
| You disagree with the code Customs determined | Apply to Customs in writing for review within 30 days from the day after receiving the duty payment notice; the goods may be collected after paying all duty or providing equivalent security; a review decision can be challenged by administrative appeal and administrative litigation | Customs Act Articles 45 to 47 |
For goods imported by a company, the input-VAT credit is claimed with the "deduction copy of the business tax payment certificate collected by Customs on behalf of the tax authority, showing the business tax amount" (Enforcement Rules of the Value-added and Non-value-added Business Tax Act, Article 38 paragraph 1 subparagraph 2). If the description, quantity or tariff code on the declaration does not match the goods actually bought and sold, the tax authority may, on audit, find that the deduction requirements are not met (Business Tax Act Article 19 paragraph 1 and Article 33), and the input tax may be disallowed; consolidated company goods declared under a single description and a single tariff code are a typical mismatch. See "Simplified declarations can claim input VAT — so why can consolidated company goods often not?" and "Import declarations, duty notices and input VAT explained".

What are the HS Explanatory Notes, and where can you read the Chinese translation? (Customs Administration update, 2026-08-25)
In one sentence: the HS Explanatory Notes are the World Customs Organization’s (WCO) official interpretation of the scope of each HS heading, including what is covered and excluded; General Provision 1 of Taiwan’s Customs Import Tariff states that classification “may also refer to” the HS Explanatory Notes, and the Customs Administration translates WCO HS Committee decisions into Chinese, amends Taiwan’s translated Notes and publishes them online. Summary based on the Customs Administration press release of 2026-08-25 and related official documents (original texts accessed 2026-10-23):
| Question | Answer | Source |
|---|---|---|
| What legal weight do the Explanatory Notes have? | The WCO states that the Explanatory Notes do not form an integral part of the HS Convention, but once approved by the WCO Council they constitute the official interpretation of the HS at the international level. General Provision 1 of Taiwan’s Customs Import Tariff provides that, besides the section and chapter notes, heading texts and the Interpretative Rules, classification “may also refer to” the HS Explanatory Notes and other relevant documents. | WCO Explanatory Notes page; Customs Import Tariff, General Provision 1 |
| Who amends them, and how often? | The WCO Harmonized System Committee (HSC) meets at least twice a year and adopts Classification Decisions on disputed goods; representative cases are turned into Classification Opinions, which the Customs Administration press release says carry the same weight as the Explanatory Notes. The HSC also reviews and amends the Notes periodically. | Customs Administration press release, 2026-08-25 |
| What examples did this update give? | ① Heading 2404: nicotine-containing products without tobacco or reconstituted tobacco, intended for nicotine intake by chewing, dissolving, sniffing, absorption through the skin or any other means (other than inhalation), are clearly classified in heading 2404 — for example tobacco-free oral nicotine pouches go to 2404.91.00 (“for oral application”).② Indoor serving robots: the note to heading 8709 was changed from vehicles “used in” factories, warehouses, dock areas or airports to vehicles “used only in” them, so serving robots used in restaurants do not fall in heading 8709 and are classified in heading 8428. | Customs Administration press release, 2026-08-25 |
| Where is the Chinese translation? | On the Customs Administration website under Home › Information › Downloads › File Downloads (web.customs.gov.tw/multiplehtml/1205). When accessed on 2026-10-23, the file was titled “HS Explanatory Notes, 2022 edition (WCO 75th session)” and provided as a ZIP archive (in Chinese). | Customs Administration press release, 2026-08-25; Customs Administration download page |
| What role do they play in classification disputes? | Customs rulings and press releases often quote “the Explanatory Note to heading xxxx” directly — the three misclassification cases above cite headings 3801, 4009 and 8441. Ministry of Finance Order Tai-Cai-Guan No. 1091015146 of 2020-07-06 provides that when Customs changes a tariff classification on the basis of WCO amendments to the Explanatory Notes and the change applies generally, it must be issued as a ministerial order published in the Executive Yuan Gazette, taking effect on the date of issue or a specified later date; where it affects import permit or inspection requirements, the trade authority must be consulted first; individual reclassifications that do not apply generally are made by Customs ex officio, and a taxpayer who disagrees may seek remedies under Articles 45–47 of the Customs Act. | WCO; MOF Order of 2020-07-06; Customs Act |
⚠️ A correct tariff code does not mean the goods may be imported: classifying oral nicotine pouches under 2404.91.00 or serving robots under heading 8428 only answers “which code”. Whether the goods may be imported from mainland China, or need inspection, still depends on the import regulations column of that tariff line (such as MW0, C02, F01 — see the section on importing mainland Chinese goods below) and on the rules of each competent authority. For classifications made before a new rule is issued, the actual Customs ruling and the effective date of the ministerial order prevail.
What is the “Special Customs Requirements” column, and what does code Z mean?
In one sentence: “Special Customs Requirements” is a column on every tariff line of Taiwan’s combined Customs Import Tariff and Import/Export Commodity Classification, using codes to flag collection matters such as no duty drawback or commodity, alcohol or tobacco tax; Z marks tariff lines where “the statistical quantity of imported goods may be declared as 0” — when a complete machine is dismantled and imported in batches, the first batch declares the quantity of the whole set and later batches declare 0. It is a statistical declaration rule, not a prohibition or inspection code.
The usage notes for this column on the Customs-Port-Trade Single Window state that it marks, with different codes, items such as no duty drawback, no bonding, commodity tax, alcohol tax, tobacco tax and health and welfare surcharge, and specific tariff increases, reductions or exemptions, after converting the scope of the original regulations into CCC codes, for reference in clearance; because the scope of the original regulations does not necessarily match the CCC codes, the column is for reference only, and in case of doubt the original regulations prevail. The official meaning of each code (accessed 2026-10-23):
| Code | Official meaning |
|---|---|
R | Non duty drawback |
R* | Non duty drawback, partially |
T | Subject to commodity tax |
T* | Subject to commodity tax, partially |
L* | Subject to specifically selected goods and services tax, partially |
N | Subject to a tariff additional note for a special tariff number |
B | Subject to alcohol tax |
B* | Subject to alcohol tax, partially |
C | Subject to tobacco tax and tobacco health and welfare surcharge |
S* | For some imports, a certificate of origin issued by the government of the country of origin or its authorized body must additionally be enclosed |
D* | For some imports, records of the farm where cattle were raised before slaughter and of the slaughterhouse, issued by the relevant government units of an FTA partner, must additionally be enclosed |
G | Special safeguard measures apply |
Z | Tariff line whose statistical quantity of imported goods may be declared as “0” (when a complete set of machinery or a composite article must be dismantled and shipped in separate packages, the main unit or first consignment declares the quantity of the complete set in the statistical quantity field, later consignments declare “0”, and all are declared under the tariff code applicable to the complete set) |
| Notice date | Tariff line and description | Change and reference no. |
|---|---|---|
| 2026-09-15 | 8480.60.00.00-0 Moulds for mineral materials | Previously blank → Z added, effective immediately; Tai-Guan-Tong No. 1151024994 |
| 2026-10-05 | 8404.20.00.00-2 Condensers for steam or other vapour power units | Previously blank → Z added, effective immediately; Tai-Guan-Tong No. 1151026780 |
📎 Both notices cite as their basis Point 7 of the Customs Import and Export Trade Statistics Operation Directions and item (11) of the usage notes for the “Special Customs Requirements” column in the combined tariff volume; the attached change table gives the same meaning of code Z as above. The notices cite item (11), while the current Single Window notes list Z as item (13) — the numbering differs but the wording is the same.
① Z only affects the “quantity (statistical)” field: when a complete machine or composite article is dismantled and imported in batches, the main unit or first batch declares the quantity of the whole set, later batches declare “0”, and every batch is declared under the tariff code for the complete set — not each part’s own code.
② Z is neither a prohibition nor an inspection code: whether the goods may be imported from mainland China or need BSMI inspection is shown in the separate “import regulations” column of the same line (MW0, C02, etc.); the two columns are independent.
③ The column is for reference only: the usage notes say the original regulations prevail in case of doubt; whether a complete machine may be classified under the complete-set code depends on the Interpretative Rules and the Customs ruling — if unsure, apply for an advance tariff classification ruling first (see above).
④ Importing a dismantled complete machine in batches is a matter for a regular import declaration (formal customs clearance). HowBridge serves the Shenzhen warehouse + Taoyuan warehouse, China → Taiwan route; for machinery and equipment, please ask customer service to assess the declaration method first.

Importing Mainland Chinese Goods into Taiwan: the Column on the Tariff Line That Decides Whether You Can Ship It at All
When people buy online in mainland China and ship back to Taiwan, many check only the duty rate before ordering — and then the parcel is held at customs. The reason: on one and the same CCC tariff line, the “duty rate” and the “import regulations” are two separate, independent fields, administered by different authorities — the duty rate is levied by the Customs Administration, Ministry of Finance under the Customs Import Tariff (《海關進口稅則》); the import regulations are laid down by the competent sectoral authorities such as the International Trade Administration, MOEA, with customs assisting in checking them at the border. So finding a 0% duty rate does not mean the item can be shipped in.
| Import Regulation Code | Official Definition | What It Means for Consolidated Shipping |
|---|---|---|
MW0 | Mainland Chinese goods are prohibited from import | ❌ MW0 = import from mainland China is prohibited: this applies to goods of mainland Chinese origin under this tariff line (other origins are not affected). Exception: small quantities of mainland Chinese goods in Chapters 25–97 may be imported without an import permit if the whole declaration is within CIF NT$32,000 and each single product is within 24 pieces (40 kg if it cannot be counted; a single product is identified by its model number, or by the line item on the declaration if there is no model number, and may not be split by size, specification or colour; stone under heading 6802 and tiles under heading 6907 must meet both 24 pieces and 40 kg). Electric motorcycles, electric bicycles and their controllers (tariff lines 8711.60.10, 8711.60.20 and 8543.70.99.50) are excluded, and Chapters 1–24 do not qualify. Inspection, quarantine and other import requirements must still be met separately. |
MP1 | Mainland Chinese goods are conditionally permitted for import | ⚠️ You must check the “List of Mainland Goods Conditionally Permitted for Import”; where that list additionally shows an MXX code (such as M63 or M68), documents from the competent authority must be attached as well |
Neither MW0 nor MP1 listed | Mainland Chinese goods are permitted for import | ✅ The mainland-origin hurdle is cleared, but the goods must still comply with the other requirements below, such as inspection and quarantine |
465 | A certificate of origin issued by the government of the exporting country or its authorized body (or an officially announced substitute document) must be attached; exempt where the goods are for personal use and the quantity does not exceed 6 kg | ⚠️ This is a “document” requirement, not the test of whether the item may be imported — a great many tariff lines that are not MW0 also carry 465 |
F01 | Import inspection must be applied for with the TFDA (Taiwan Food and Drug Administration, MOHW) under the Regulations of Inspection of Imported Food and Related Products (《食品及相關產品輸入查驗辦法》) | All food items require import inspection (F02, by contrast, applies only “where the item is for food use or contains food ingredients”) |
C01/C02 | Goods announced by the BSMI (Bureau of Standards, Metrology and Inspection, MOEA) as subject to import inspection (C02 means that “some of the goods under this item” are subject to it) | Must pass BSMI commodity inspection |
B01 | Must be handled in accordance with the List of Animals and Plants Subject to Quarantine (《應施檢疫動植物品目表》) of APHIA (Animal and Plant Health Inspection Agency, Ministry of Agriculture) | Animal and plant products require quarantine |
121 | Import permit issued by the International Trade Administration (MOEA); the import declaration must be filed with this permit | ⚠️ In principle, the permit must be obtained before the declaration (exceptions under the Regulations Governing Import of Commodities); see “What is import regulation code 121?” and “How to apply for an import permit” |
Take mainland-grown green tea (CCC 0902.10.00.00-7): its import regulation field reads “465 F01 MW0”, which means three gates apply at the same time: 465 requires a certificate of origin, F01 requires an import inspection application to the TFDA, and MW0 means goods of mainland origin may not be imported (MW0 = import from mainland China is prohibited; the small-quantity import permit exemption does not apply to Chapters 1–24).
🔴 The easiest thing to misread: the 465 rule contains the sentence “goods imported for personal use in a quantity not exceeding 6 kg are exempt from attaching it” — but that waives only “the certificate of origin document”; it does nothing whatsoever to lift MW0. So mainland green tea bought “for personal use, only 5 kg” still may not be imported. Whenever you see a proviso saying “exempt from attaching” or “exempt from a permit”, go back and check whether MW0 is still there.
These are two independent sets of rules. The duty-free threshold governs “whether tax is payable”; MW0 governs “whether it may enter at all” (MW0 = import from mainland China is prohibited; the small-quantity import permit exemption does not apply to Chapters 1–24). A mainland dried shiitake mushroom marked MW0 still may not be imported, even if it is worth only NT$300 — far below the NT$2,000 duty-free threshold.
The consequences come in two kinds: if you declare truthfully, customs will order the goods to be returned within a set period under Article 96 of the Customs Act, and if that is not done within the deadline the goods are sold off or destroyed at your own expense; if you misdeclare the origin or the description in an attempt to get around the rules, then — because a Ministry of Finance directive expressly defines “controlled goods” as covering “mainland goods that the Regulations Governing Trade Between the Taiwan Area and the Mainland Area prohibit from import” — it amounts to evasion of controls, and under Article 37 of the Customs Anti-smuggling Act, which refers on to Article 36, the goods are confiscated and a fine of up to 3 times the value of the goods is imposed.
(Low-value duty exemption: a consignment with a customs value of NT$2,000 or less is exempt from customs duty and business tax, but this ceases to apply once you exceed 6 times within a half-year period, i.e. from the 7th time onward; the count restarts on 1/1 and 7/1 each year.)
Based on public data from the International Trade Administration, MOEA (basis: number of tariff lines; scope: Chapters 1~97): about 77% are permitted for import, about 3% are conditionally permitted, and about 20% are prohibited. But the average is deceptive — for agriculture, fisheries, livestock and food (Chapters 1~24) the prohibited share runs to about 36%, while for industrial goods (Chapters 25~97) it is about 15%, so food is more than 2 times as likely to be blocked as an industrial product. A real example: among mainland teas only pu-erh tea is currently open to import, while green tea, black tea and oolong tea may not be imported (expressly listed in a 2025 Customs Administration press release); and among dried fungi, both dried wood ear and dried shiitake carry MW0 and may not be imported. Goods of the same kind can be treated differently because they fall on different tariff lines, so check item by item and never reason from “a similar product is allowed”.
These cases must be kept apart; mixing them up is exactly what gets shipments held:
① Food / agricultural products: the Customs Administration states in writing that “food not open to import that is sent by mail requires case-by-case import permit documents, and the small-quantity permit-exemption rules do not apply”. Regardless of personal use, regardless of the amount of money, regardless of the quantity, it cannot be shipped in.
② Industrial products (tariff Chapters 25~97): small quantities of mainland Chinese goods in Chapters 25–97 may be imported without an import permit if the whole declaration is within CIF NT$32,000 and each single product is within 24 pieces (40 kg if it cannot be counted; a single product is identified by its model number, or by the line item on the declaration if there is no model number, and may not be split by size, specification or colour; stone under heading 6802 and tiles under heading 6907 must meet both 24 pieces and 40 kg). Electric motorcycles, electric bicycles and their controllers (tariff lines 8711.60.10, 8711.60.20 and 8543.70.99.50) are excluded, and Chapters 1–24 do not qualify. Inspection, quarantine and other import requirements must still be met separately. There is no guarantee that any industrial product in a small quantity can be shipped in.
③ Separate quantity allowances exist for mainland goods carried by inbound travellers, and they never apply to consolidated shipping or mail — taking “a traveller may bring it in” to mean “it may be shipped” is the most common misjudgement of all.
① The International Trade Administration, MOEA “Mainland Goods Import Query” — search by tariff line or by Chinese/English product name and see directly whether the item is MW0.
② HowBridge’s 12,000+ tariff code search — enter the product name in Chinese and see the CCC tariff line, the duty rate and the import regulations at the same time.

The ECFA Early Harvest List and the Certificate of Origin: how it is done on the mainland side, and whether it can be done at all
This is where “Column 2” of the three tariff columns connects to mainland Chinese goods. The list of countries eligible for Column 2 of the Customs Import Tariff (《海關進口稅則》) includes “CN People’s Republic of China (applicable only to goods on the ECFA Early Harvest List)” — in other words, not all mainland goods can use the preferential rate; only goods on the Early Harvest List can. Taiwan’s Early Harvest List of tariff cuts for the mainland originally comprised 267 items (subdivided as HS versions changed, so the current correspondence table lists 354 items); all were reduced to zero duty from 1 January 2013, and the list contains no agricultural products at all.
⚠️ Get the name right: the Taiwanese authorities call it the “ECFA certificate of origin”, the mainland authorities call it the “certificate of origin (原產地證書)”, and neither side uses a FORM number; the “FORM F” that circulates informally is in fact the certificate of origin under the China–Chile Free Trade Agreement and has nothing to do with ECFA.
1First confirm the goods are on the “Taiwan-side Early Harvest List”
Match the first 8 digits of the product’s CCC/HS code against the “ECFA Taiwan-to-Mainland Tariff Code Correspondence Table” published by the Customs Administration, Ministry of Finance. Goods not on the list are charged the general rate (Column 1) whether or not a certificate of origin exists — confirm this step first, or nothing that follows means anything.
2The “mainland exporter” applies for the certificate of origin locally
This certificate is applied for by the exporting side; an importer in Taiwan cannot obtain it on their own — the Customs Administration’s own wording is “to apply for a mainland certificate of origin, please have the exporter contact the local issuing body directly”.
Where is it applied for on the mainland? Under Article 17 of China’s Regulations on the Place of Origin of Import and Export Goods, the issuing bodies form two parallel systems — the Customs and the China Council for the Promotion of International Trade (CCPIT) and its local branches — and the exporter may choose freely between them. Online entry points: the “China International Trade Single Window” (singlewindow.cn), the Customs government services platform (online.customs.gov.cn), or the CCPIT filing system (co.ccpit.org).
The procedure: on the mainland, the “origin enterprise record-filing” requirement was abolished with effect from 2023-11-01 (November 1, 2023), so applications can now be filed directly online, but the applicant must still be a registered market entity holding a Unified Social Credit Code. After the application is drafted and submitted online, review takes about 2 working days; once issued, the certificate can be self-printed, and Customs charges no fee.
🔴 Timing is decisive: it must be issued “before” the export declaration on the mainland; the certificate is valid for 12 months from the date of issue, and for ECFA cases the window for retroactive issuance is only 90 days.
3The shipment must satisfy the “direct transport” rule
In principle the goods must be transported directly between the two sides of the Strait. If they are transshipped through a third place (Hong Kong and Macau are both treated as a third party without exception), all of the following must be met at once: the routing is required on geographical or transport grounds; no trade or consumption took place in the third place; no processing other than loading, unloading and repacking occurred; the stay does not exceed 60 days and the goods remain under that place’s customs supervision throughout; and a transshipment certificate is submitted at the time of import (for routing via Hong Kong, a “Hong Kong Customs confirmation letter”).
4“Declare it proactively” at Taiwan customs and attach the original
Under the current Operational Directions for Customs Clearance of Goods Imported under ECFA (《ECFA 進口貨物通關作業要點》), enter “PT” in the “free trade agreement preferential tariff marking” field of the import declaration and write the certificate number in the “certificate of origin number” field (the 1st digit is left blank; entry starts from the 2nd digit), while attaching the original certificate of origin issued on the mainland — the Ministry of Finance states expressly that a certificate printed from a PDF file converted by the exporter may not be used for customs clearance.
🔴 Miss this step and it cannot be made good afterwards: where it was not declared proactively at the time of the customs declaration, customs will not accept any certificate of origin submitted later. In addition, one certificate of origin can cover only one import declaration, with no more than 20 line items.
5If the certificate cannot be attached in time, a deposit allows release first
“PT” must still be declared; clearance is then carried out by paying a deposit, and a valid certificate of origin must be submitted within 4 months after the goods are released, on the basis of which duty is settled or the deposit refunded.
The procedure above is designed for formal trade between companies. For personal online shopping via consolidated shipping there are four practical barriers, and any single one of them is enough to block the route on its own:
① The certificate is applied for by the mainland exporter, and the applicant must be a registered market entity holding a Unified Social Credit Code (統一社會信用代碼) (a company or an individually-owned business) — a natural-person consumer is not eligible to apply.
② It must be issued before the export declaration on the mainland, whereas by the time you place an online order the seller has long since shipped the item as ordinary goods.
③ The importer field on the certificate has to name an importer registered on the two sides of the Strait, and at the moment of shipping the seller has no way of knowing who will finally import the goods, or on which Taiwan import declaration.
④ One certificate of origin covers only one import declaration, whereas consolidated shipping is by its very nature many buyers and many sellers packed into one box.
So for mainland goods moving by personal consolidated shipping, Column 1 rates apply in practice, without exception. The real way to save is to check the duty rate of the product’s own CCC tariff line before ordering (plenty of 3C products, books and some skincare items are at 0% to begin with) and to check whether it carries MW0 (import from mainland China is prohibited; exception: small quantities in Chapters 25–97 need no import permit if the whole declaration is within CIF NT$32,000 and each single product is within 24 pieces, with a 40 kg limit only for goods that cannot be counted; electric motorcycles, electric bicycles and their controllers are excluded, and Chapters 1–24 do not qualify) — rather than studying a certificate you can never obtain, first make sure the thing can be shipped in at all.
CCC Code — Frequently Asked Questions
Z marks a tariff line where the statistical quantity field of the import declaration may be declared as “0”: when a complete set of machinery or a composite article has to be dismantled and shipped in separate consignments, the main unit or first consignment declares the quantity of the complete set, later consignments declare “0”, and all are declared under the tariff code applicable to the complete set. Whether goods may be imported or need inspection is shown in the separate “import regulations” column of the same tariff line (for example MW0, C02).Related Reading
