Certificate of origin
A certificate of origin is a trade document that states the country where goods were manufactured or substantially transformed. Exporters obtain it from their local chamber of commerce or a national authority. Importers submit it to customs to claim preferential duty rates under free trade agreements or to comply with non-preferential origin rules.
What a certificate of origin does
Customs officers at the destination check where the goods originate to determine the duty rate. Trade agreements lower or eliminate duty for qualifying origins. A certificate proves the goods meet those origin rules, so the buyer can claim the preference and pay less duty.
Certificates usually state the exporter name and address, the consignee, the product description, the HS code, and the country of origin. Preferential certificates also reference the trade agreement under which the goods qualify. When a chamber or authority issues it, they stamp and sign it, and the exporter or freight forwarder presents it with the commercial invoice and other shipping documents.
Chambers of commerce in most countries issue certificates of origin. In some systems, designated government agencies issue them. The World Customs Organization maintains international standards, and the International Chamber of Commerce publishes model forms. Some newer trade agreements use self-certification instead, where the exporter or producer signs a declaration without a third-party stamp.
Preferential vs non-preferential certificates
Preferential certificate of origin
Certifies that goods qualify for reduced or zero duty under a free trade agreement or trade preference scheme. The certificate names the agreement (such as USMCA or the India-UAE CEPA) and confirms the goods meet the rules of origin. The buyer submits it to customs to claim the lower duty rate.
Non-preferential certificate of origin
States the country of manufacture or substantial transformation without claiming a trade preference. Buyers may request it for customs clearance, trade policy purposes, or buyer requirements even when no preferential duty applies. It confirms origin but does not reduce duty.
Self-certification
Some trade agreements allow the exporter or producer to certify origin by signing a declaration on the invoice or a separate document, without a third-party stamp. USMCA, for example, replaced NAFTA certificates with self-certification. The certifying party must still have documentation proving the goods meet the rules of origin.
Why certificates appear on export quotes and invoices
A preferential certificate can lower or remove the duty a buyer pays on qualifying goods. An exporter who qualifies must tell the buyer on the quote or proforma invoice so the buyer knows the goods are preference-eligible.
Duty reduction
Free trade agreements lower duty for goods that meet origin rules. A buyer importing from a preference-eligible country pays less duty than from a non-qualifying origin. The certificate is the proof customs needs to grant that reduction.
Landed cost impact
Duty is a percentage of the customs value. Lower duty reduces the buyer’s landed cost per unit. When comparing suppliers in different countries, the buyer factors in which origins qualify for preference and how much duty each pays. An exporter who qualifies for preferential treatment delivers a lower landed cost even at the same FOB price.
Rules of origin compliance
Trade agreements define origin by criteria such as wholly obtained, substantial transformation, or regional value content. An exporter must prove their goods meet the test. The certificate attests to compliance, and the exporter keeps supporting records in case customs audits the claim.
Quote and proforma statements
An exporter who qualifies should state the origin and the applicable trade agreement on the quote or proforma invoice. The buyer then knows to request the certificate before shipment and to claim preference at import. Stating it up front prevents disputes after the goods land.

Terms certificate of origin connects to
HS code
The product classification code that determines the standard duty rate. A preferential certificate of origin references the HS code and enables a lower rate under a trade agreement. The code appears on the certificate and on the commercial invoice.
Landed cost
The total cost to receive goods at the buyer’s warehouse. Landed cost includes product cost, freight, insurance, duty, brokerage and delivery. A preferential certificate reduces the duty component, lowering the buyer’s landed cost.
Proforma invoice
The preliminary invoice issued before shipping. An exporter who qualifies for preferential treatment should state the country of origin and the applicable trade agreement on the proforma, so the buyer knows to request the certificate before shipment.
Incoterms
Trade terms (FOB, CIF, DDP) that define who pays freight, insurance and duty. Under DDP, the seller delivers the goods cleared for import and pays the duty. If the goods qualify for preferential treatment, the seller claims the preference and pays the lower duty rate.
Cost recipe
The pricing rules behind a custom product quote. Origin and certificate eligibility are stated separately on the proforma invoice.
