Certificate of Origin vs Declaration of Origin: When You Need Which
Both prove where your goods were made, but customs treats them very differently. Here's the practical guide for USMCA, CPTPP, EU-UK TCA, and other free-trade agreements that hinge on origin proof.
Short version. A Certificate of Origin is a standalone document that formally certifies where goods were manufactured, typically issued by a Chamber of Commerce or equivalent authority. A Declaration of Origin is a shorter statement signed by the exporter on the commercial invoice itself or on a separate one-line attachment. Customs treats them differently: a Certificate is the gold standard for preferential duty claims; a Declaration is sufficient for routine non- preferential origin marking.
The four types you’ll meet
- Non-preferential Certificate of Origin — the classic CoO from a Chamber of Commerce. Used for routine origin proof, letter-of-credit transactions, and some restricted-goods entries.
- Preferential Certificate of Origin— issued or endorsed by the exporter’s customs authority. Names the specific FTA the goods qualify under (e.g. EUR.1, A.TR, Form A).
- Origin Declaration on commercial invoice — self-signed statement embedded in the invoice, stating origin and (for preferential claims) the FTA criterion met. Used under USMCA, CPTPP, EU-UK TCA when self-certification is allowed.
- Country-of-origin field on the commercial invoice — the simplest declaration. Just “CN”, “US”, etc. on each line item. Sufficient for most non-preferential shipments.
When you need each
Just the country-of-origin field on the invoice
Routine non-preferential shipments where no FTA benefit is being claimed. Customs uses this to apply the standard MFN duty rate. No chamber stamp, no separate document — just the ISO code on the line items. This covers the majority of B2B and e-commerce shipments.
Standalone non-preferential Certificate of Origin
Required when:
- The buyer’s letter of credit explicitly demands one (banks often do).
- The destination country requires it for specific commodity categories — textiles, foodstuffs, pharmaceuticals.
- The shipper wants formal proof of origin for litigation, insurance, or trade-policy purposes.
Issued by Chambers of Commerce. Most chambers process online applications in 1–2 business days for $25–$100. The certificate carries the chamber’s seal and a registration number.
Preferential Certificate (FTA-specific)
Required when claiming reduced or zero duty under a Free Trade Agreement, and the agreement’s rules require a formal certificate rather than self-certification.
| Agreement | Document | Issuer |
|---|---|---|
| USMCA (US-Mexico-Canada) | Self-certification statement | Exporter / producer / importer |
| CPTPP (Trans-Pacific) | Self-certification statement | Exporter / producer / importer |
| EU-UK Trade and Cooperation Agreement | Statement on origin | Exporter (registered on REX system) |
| EU bilateral FTAs (Korea, Vietnam, Japan, etc.) | EUR.1 movement certificate or REX statement | Customs / exporter |
| Pan-Euro-Mediterranean | EUR-MED certificate | Customs of exporting country |
| GSP (Generalised System of Preferences) | Form A | Designated authority in beneficiary country |
| EU-Türkiye Customs Union | A.TR movement certificate | Customs of exporting country |
Origin declaration on the commercial invoice
Under modern FTAs (USMCA, CPTPP, EU-UK TCA), an exporter can self-certify origin by adding a specific statement to the commercial invoice. No chamber, no customs endorsement. The statement is governed by the FTA’s required wording and must identify:
- Which FTA is being claimed
- Which origin criterion the goods meet
- The producer (if different from exporter)
- The exporter’s authorised representative signature / printed name
Example USMCA wording on a commercial invoice:
“I certify that the goods described in this document qualify as originating goods under the rules of origin of the USMCA. The goods originate in the United States and meet criterion B. Authorised signature: [name], [title], [date].”
The cost of getting it wrong
Three failure modes:
- Claiming preferential origin without proof. Customs disallows the claim, charges full MFN duty, and may assess penalties.
- Wrong origin on the country-of-origin field. Even on non-preferential shipments, declaring the wrong origin country (where goods were warehoused vs. manufactured) is misrepresentation. See the customs invoice mistakes post for context.
- Self-certifying without qualifying.Under USMCA, self-certification means the signer is legally responsible for the truth of the statement. Saying the goods qualify when they don’t exposes the certifier to civil and criminal penalties.
FAQ
Is a Certificate of Origin always required?
No. A standard Certificate of Origin is required only when the destination country, an importer's bank, or a buyer's contract specifically asks for one — most commonly for non-preferential origin proof or letter-of-credit transactions. Preferential certificates (USMCA, EUR.1, EUR-MED) are required only when claiming reduced or zero duty under a specific FTA.
Can I just write 'Made in [country]' on the commercial invoice?
Yes — that's a non-preferential origin declaration and it's sufficient for most shipments where no FTA is being claimed. The country of origin field on the commercial invoice is what customs uses for non-preferential duty assessment. A separate Certificate of Origin is only needed when a higher-stakes proof is required.
Who issues a Certificate of Origin?
Non-preferential certificates are typically issued by Chambers of Commerce in the exporting country. Preferential certificates (EUR.1, EUR-MED) are issued or endorsed by the customs authority. Self-certification is allowed under some agreements (USMCA, CPTPP) — the exporter signs their own statement on commercial documents.
What's the cost of getting a Certificate of Origin?
Non-preferential certificates from a Chamber of Commerce typically cost $25–$100 per shipment depending on the chamber, with same-day or 1–2 day turnaround. Preferential certificates are usually free but take 2–5 days. Self-certification under USMCA / CPTPP costs nothing — you write the statement on your commercial documents.
