Q1159. How are foreign certificates of origin (CO) processed for Thai customs clearance?
Answered by the NYC Visa & Translation legalization desk
Certificates of origin are normally handled through the applicable customs and trade-agreement procedures, rather than automatically through Thai MFA legalization. First, determine whether the shipment claims preferential tariff treatment or uses a non-preferential certificate. Check Thai Customs’ requirements for the relevant agreement, including the authorized issuer, prescribed form or electronic record, origin criteria, and supporting shipment documents. Ensure the certificate matches the invoice and goods description. Only arrange consular legalization if the receiving authority specifically requires it, using the route confirmed by the relevant Thai embassy. A common pitfall is assuming a legalized generic certificate can replace the origin proof prescribed by a trade agreement. Verify the applicable origin requirements with Thai Customs before filing.
