Key takeaways
- A certificate of origin states the country in which goods were wholly obtained or last substantially transformed.
- Non-preferential certificates support ordinary customs and trade rules. Preferential ones support reduced duty under a trade agreement.
- Certificates are often issued by chambers of commerce. Some trade agreements let exporters certify origin themselves.
- Origin is not where goods shipped from. A wrong origin is a misdeclaration.

What a certificate of origin is
A certificate of origin is a document that declares the country where goods were produced, made or last substantially transformed, used by customs to apply duties and trade rules.
Customs uses origin for the duty rate, for quotas, for sanctions and anti-dumping checks, and for claims under free trade agreements. A buyer may ask for one in a purchase contract, a bank may ask for one under a letter of credit, and an importer may need one to claim a preferential rate.
A furniture exporter in Vietnam sells to a buyer in Europe. The buyer wants the preferential duty available under a trade agreement. The exporter applies for a preferential certificate of origin, attaching production records that show the chairs qualify.
Without the certificate the importer would pay the standard duty rate, which would be higher on the whole shipment.
Two kinds
| Type | What it supports | Who issues it |
|---|---|---|
| Non-preferential | Origin for ordinary customs and trade rules, letters of credit | Chambers of commerce or authorised bodies |
| Preferential | Reduced or zero duty under a trade agreement | Authorised bodies, or the exporter in self-certification schemes |

What it shows
| Field | What goes in it | Why it matters |
|---|---|---|
| Exporter and consignee | Names and addresses. | Must match the invoice. |
| Description of goods | Items, quantities, marks, HS code. | Must match the commercial invoice. |
| Country of origin | Where goods were wholly obtained or last substantially transformed. | The point of the document. |
| Transport details | Mode, route and vessel, where required. | Some agreements need it. |
| Invoice number and date | Reference to the commercial invoice. | Ties the documents together. |
| Declaration and certification | Exporter declaration and issuer stamp. | Makes it official. |
The certificate must agree with the commercial invoice and the packing list. The wider export set is on shipping documents.
Where it goes wrong
- Origin declared as the country of shipment, not of manufacture.
- Description that does not match the invoice.
- No records to back a preferential claim.
- Expired or late certificates.
- Self-certifying without checking the rules of origin.
- Origin has been worked out under the right rule.
- Production records are kept.
- Description and HS code match the invoice.
- Issuing body or self-certification rules are known.
- Time is allowed for issue.
- Copy is ready for the shipment pack.
