AEO (Authorized Economic Operator) is an international-standard customs certification for supply-chain security and compliance. Taiwan's program has two tiers: General AEO and Security-Certified AEO (AEO-S). AEO-S enjoys the lowest inspection rates and may have selected shipments upgraded to exemption — resulting in faster clearance and lower hold risk.
AEO (Authorized Economic Operator) is an international-standard certification issued by Customs to supply-chain entities that meet security and compliance requirements. Taiwan's AEO program has two tiers: "General AEO" — enjoys reduced document review rates and lower cargo inspection rates; "AEO-S (Security-Certified AEO)" — enjoys the lowest inspection rates, and if selected for inspection may be upgraded to exemption; shipments with a declared FOB value of NT$100 million or more may qualify for direct release without examination. HowBridge Logistics works with AEO-certified customs brokers for clearance, combined with dual-clearance and reminders that help recipients complete EZWay real-name verification and declaration confirmation, reducing the risk of holds, supplementary filings, and clearance delays while improving release speed and consistency. According to a Ministry of Finance press release dated 13 May 2025, there are 948 AEO-certified enterprises nationwide (524 General AEO + 424 Security-Certified AEO), accounting for roughly 50% of annual total trade value. Their average clearance time is more than 3× faster than non-AEO operators. Taiwan has also signed Mutual Recognition Arrangements (MRAs) with 10 countries including the US, Singapore, Japan, South Korea, and Australia, granting priority clearance in signatory countries on export.
