Certificate of Origin Explained
What a certificate of origin certifies, who issues it, the difference between non-preferential and preferential certificates, and why the details must match every other document.

A certificate of origin certifies the country in which the goods were produced. For agricultural commodities that is usually straightforward — the crop grew where it grew — but the document still carries weight, because customs authorities in the importing country use it for tariff classification, for statistical purposes and, where a trade arrangement exists, for preferential duty treatment.
Who issues it
Certificates of origin are typically issued by a recognised chamber of commerce in the exporting country, or by another competent authority designated for the purpose. The exporter applies, supplying the commercial documents and any evidence of origin the issuing body requires, and the certificate is issued against the specific consignment.
Non-preferential and preferential certificates
- Non-preferential
- The ordinary certificate, stating country of origin for general customs purposes. This is what most consignments carry.
- Preferential
- Issued under a specific trade arrangement between the exporting and importing countries, allowing reduced or zero duty where the goods meet the arrangement's origin rules. The form, the rules and the eligibility are set by that arrangement, not by the exporter.
Why the details matter
The certificate has to reconcile with everything else in the document set: the commercial invoice, the packing list and the bill of lading. Product description, quantity, weights, marks, container numbers and consignee details all need to match. A discrepancy that looks trivial — a description worded differently, a weight rounded differently — is exactly what causes clearance delays and, under a letter of credit, document rejection.
Country-of-origin marking on the bags themselves must also be consistent with the certificate. Where bags are marked "Produce of Tanzania", the certificate cannot say something else.
Timing
The certificate is issued against a shipped consignment, so it follows loading rather than preceding it. Where the buyer needs the document set within a defined period — commonly the case under a letter of credit with a presentation deadline — the issuance timeline needs to be built into the shipment plan. Reissuing a certificate after the fact, for example after a change of consignee, is slow and sometimes not possible.
