Certificate of Origin requirements ensure exporters provide evidence of origin and supporting documents before issuance under the trade agreement. Exporters or producers must apply to the authorised issuing body for a Certificate of Origin by submitting an application with supporting evidence establishing origin, including cost breakdowns, Annexure A information consistent with the invoice, and the commercial invoice; multiple items may be declared if each qualifies separately, and issuing bodies may use risk management and conduct verifications to ensure applications are complete, duly signed, and correspond to supporting documents.
