Certificate of Origin procedures secure preferential tariff claims through designated issuance, documentary verification, and retroactive checks. Designated government Issuing Authorities shall issue Certificates of Origin, verify origin through documentary checks and pre exportation examinations, and ensure applications conform to the Rules of Origin. Certificates must follow prescribed form, language and distribution, indicate applicable Rules of Origin and local value added content, and be retained along with supporting documents. Importing Party Customs may request retroactive checks on authenticity or origin determination, suspend preferential treatment pending results, and the Issuing Authority must respond within specified timeframes; information exchanged is confidential and Authorities shall cooperate on suspected fraud.
