Certificate of origin against declaration of origin
Both say where goods were produced. The difference is certification: a certificate is stamped by a chamber of commerce, a declaration is your own signed statement. Which you need is decided by the destination and by whoever is paying, not by preference.
If the destination, the buyer or a letter of credit asks for a certificate of origin, self-certifying will not satisfy them — you need the chamber stamp. Where nobody has specified, a declaration is faster, free, and usually enough.
| Certificate of Origin | Declaration of Origin | |
|---|---|---|
| Who certifies | A chamber of commerce, after checking your documents. | You, on your own letterhead. |
| Cost and time | A fee, plus turnaround. Days, sometimes longer. | Neither. Signed and sent. |
| Accepted where | Everywhere, including destinations that require certification. | Where the destination and the buyer accept self-certification. |
| Letter of credit | What a credit naming a certificate expects. | Discrepant if the credit says certificate. |
| Legalisation | Can be legalised by a consulate on top of the stamp. | Generally cannot. |
| Preferential duty | No. Non-preferential only. | No. Non-preferential only. |
Neither one claims a duty preference
This is the mistake that costs money. Both documents are non-preferential: they state origin, but they claim no reduced rate under a trade agreement. A preference claim needs that agreement's own instrument — a USMCA certification for North America, an EUR.1 or origin declaration for EU preferential trade, a Form A under GSP. Presenting a general certificate for a preference claim gets the claim refused, and the duty saving was usually the entire point.
Self-certified does not mean informal
A declaration of origin carries the same exposure as a certificate. You are stating a fact a customs authority relies on, and being wrong is being wrong regardless of who stamped it. The chamber verifies your paperwork is internally consistent; it does not verify where the goods were actually made. That was always your responsibility and it still is.
Some destinations need a third step
Several Middle Eastern markets require consular legalisation on top of the chamber stamp — the certificate goes to the destination country's embassy after the chamber has signed it. That chain takes longer than most people expect and cannot be started after the goods have shipped. If you are shipping somewhere that requires it, find out at quotation stage.
Certifies where goods were produced. Usually stamped by a chamber of commerce and required to claim tariff treatment or satisfy a letter of credit.
A self-certified origin statement made by the exporter, used where a full chamber-stamped certificate of origin is not required.
+How do I know which one my buyer needs?
Ask, and ask specifically. “Certificate of origin” is used loosely to mean either. The question that gets a useful answer is whether it must be stamped by a chamber of commerce.
+Can I issue a declaration if I did not make the goods?
Yes, but you are declaring origin on the basis of what your supplier told you, and you carry the consequence if they were wrong. Get their declaration in writing.
+Does a declaration of origin need to be notarised?
Not normally. If someone asks for notarisation, they are usually reaching for certification, and a chamber-stamped certificate is what they mean.
