Which documents are typically required to prove origin under rules of origin?

• A. Only Certificate of Origin.
• B. Commercial invoice and packing list.
• C. Certificate of Origin, commercial invoice, packing list, and supplier's declaration or forms required by the trading partner.
• D. Export license and shipping document.

Answer: (C)

Proving origin under rules of origin relies on a set of documents that together establish that the goods meet the origin criteria for tariff treatment. A Certificate of Origin identifies where the goods originate, but customs and trading partners often require additional evidence to verify the claim. The commercial invoice provides the buyer, seller, description, and value of the goods, which helps confirm what was shipped and supports the origin claim with financial details. The packing list shows exactly what is in each package, confirming quantities and packaging and ensuring the goods described in the invoice match the shipment. A supplier's declaration or forms required by the trading partner offer an official statement from the seller that the goods comply with the origin requirements of the applicable agreement or regime.

Together, these documents form a complete package that reliably proves origin for preferential treatment. Relying on only a certificate of origin, or only the commercial invoice and packing list, or including export licenses and shipping documents, does not provide the full set of evidence typically needed to establish origin under most rules of origin.
