Verification of origin permits customs to request documents, suspend duties pending determination, and grant preferential tariff treatment.

Verification of origin allows importing customs to determine origin by sequentially requesting information from the importer, then from the exporting Party's competent authority to verify the authenticity and accuracy of a Certificate of Origin and supporting documents, and then from the exporter or producer if needed. Verification may include on-site visits and occur at declaration or before/after release. Requests to exporters/producers are limited to origin-related information, must provide a reasonable response period, and importing customs must notify the exporting Party. Goods may be released subject to duties or security; confirmed originating goods receive preferential tariff treatment and refunds or security release as appropriate.
