Origin documentation obligations require exporters to retain records, allow verification visits, and risk losing preferential treatment. Rule 19 requires Exporters, Producers, Manufacturers and Approved Exporters to submit minimum information and supporting documents for a Certificate of Origin only where goods meet origin criteria, retain commercial and customs records for at least five years from issue of the Proof of Origin, make records available for inspection on request, notify recipients of changes affecting certificates, and permit verification visits; false representations attract penalties and refusal of verification may lead to denial of preferential benefits.
