Short answer
A certificate of origin is a form, on paper or electronic, in which a government authority or an empowered body expressly certifies that the goods it covers are considered originating under the applicable rules of origin (World Customs Organization, Guidelines on Certification of Origin). In practice, chambers of commerce issue many of them. It is one kind of proof of origin, not the only kind, and an importing customs authority asks for it only when it needs it.
Who searches this: a buyer, exporter or procurement officer who has been asked for a “certificate of origin” or “country of origin certificate” and needs to know what the document is, who issues it and whether the shipment needs one. This page covers the general, non-preferential document used in trade. It does not cover vehicle certificates of origin, which answer a different question.
Definition and scope: certificate, self-issued certificate and declaration
The WCO guidelines separate several documents that people often lump together. “Proof of origin” is the umbrella term: a document or statement, on paper or electronic, that serves as prima facie evidence that the goods satisfy the origin criteria under the applicable rules of origin. It includes three forms.
| Form of proof | Who certifies origin (WCO wording) |
|---|---|
| Certificate of origin | The government authority or body empowered to issue it expressly certifies that the goods are considered originating under the applicable rules of origin. |
| Self-issued certificate of origin | A specific form in which the producer, manufacturer, exporter or importer certifies origin. |
| Declaration of origin | A statement on the commercial invoice or another document by the producer, manufacturer, exporter or importer. |
This is why the search variants overlap. “Certificate of country of origin”, “country of origin certificate” and “origin of certificate” usually point to the first row. A supplier who says it will “declare” origin on the invoice is offering the third row, which is a different document with a different issuer.
How a certificate of origin is issued
The International Chamber of Commerce states that certificates of origin are issued by chambers of commerce around the world. Its Certificates of Origin Guidelines, produced by the ICC World Chambers Federation, cover the issuing procedures for non-preferential certificates, the determination and verification of origin, the chambers’ involvement with preferential certificates, and digitalization. The revised edition introduces the International Certificates of Origin Accreditation Chain, created in 2012. ICC also notes that chambers offer digital application, issue and verification.
The practical point for a buyer is that the issuer is an authority or accredited body in the exporting country, applying the origin rules of that country. That has a consequence covered below under misunderstandings.
Preferential and non-preferential origin
The WCO guidelines distinguish preferential from non-preferential proofs of origin. This page concerns the non-preferential case, the general origin document that is not tied to a trade agreement. For a worked example of agreement-based certification, see USMCA rules of origin.
When is a certificate of origin required?
The WCO gives three limits that most how-to articles omit. They are guidance to customs administrations, so what a given country demands is set by that country.
- Not by default. As a general rule, non-preferential proofs of origin should not be required for goods on which no specific trade policy measure applies (Guideline 14).
- Only for named purposes. A non-preferential proof may be required only for the measures provided for in Article 1(2) of the WTO Agreement on Rules of Origin (Guideline 15).
- Not to set customs value. A proof of origin shall not be required solely to determine the customs value of the goods (Guideline 16). Customs value rests on the transaction value, the price actually paid or payable, and an origin document gives no assurance about price.
The WCO adds that possession or presentation of proof of origin is generally required only when the importing country’s customs authority asks for it, for instance for origin marking, and recommends requesting it case by case when deemed necessary.
A checklist for buyers asked for, or offered, an origin document
Each item follows from the sourced statements above.
- Ask which form is meant: a certificate issued by an authority or chamber, a self-issued certificate, or a declaration on the invoice.
- Ask who requires it: the importing customs authority, a contract, or a letter of credit. The WCO ties the customs requirement to the importing authority.
- Check that the document covers the goods on the shipment, since a certificate certifies that “the goods to which the certificate relates” are originating.
- Do not expect the document to settle price or customs value (Guideline 16).
- For marking questions on imported devices, read country of origin marking for imported medical devices, because marking and certification are separate.

Common misunderstandings
It is not proof of price or customs value
Guideline 16 states that proof of origin is not to be required solely to determine customs value, because it says nothing about the price paid or payable.
A non-preferential certificate is not binding on the importer’s customs
The WCO notes that a non-preferential proof of origin can merely serve as an indication of origin according to the rules applicable in the exporting country. The importing customs authority may not treat it the same way.
It is not a quality or safety approval
The definitions above concern origin under rules of origin only. A certificate of origin says where goods are considered to originate; it does not state that a product meets quality, safety or regulatory requirements.
“Made in” marking is a separate matter
Origin marking on a product is a customs marking rule; the certificate is a document. See the marking guide linked above.
FAQ
What is a certificate of origin?
A form, paper or electronic, in which an empowered authority or body certifies that the goods it covers are considered originating under the applicable rules of origin (WCO).
What is the difference between a certificate of country of origin and a country of origin certificate?
None in substance; both phrases name the same kind of document. The distinction that matters is who certifies it: an authority or chamber, the company itself (self-issued), or a declaration on the invoice.
Who issues a certificate of origin?
Chambers of commerce around the world issue them, according to the ICC, under ICC guidelines and the accreditation chain it introduced.
Is a US certificate of origin a specific form?
Rules depend on the importing country’s customs authority and on the destination’s requirements; no single US form applies to every shipment. For USMCA, see the linked guide on USMCA rules of origin.
Do I always need one to import goods?
No. The WCO guidance is that non-preferential proofs should not be required where no specific trade policy measure applies, and are requested case by case when needed.
