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 EZWay real-name direct connection, reducing the risk of holds, supplementary filings, and clearance delays while improving release speed and consistency. According to Taiwan Customs (Ministry of Finance) data and academic research, there are approximately 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 (per Public Finance Research, Vol. 52, No. 1).
