Why do you need a CUSMA certificate of origin?
Last updated 3 October 2026
Quick answer
Because the claim rests on it. Under CUSMA, an importer claims preferential tariff treatment based on a certification of origin, and must have a valid one in its possession when it makes the claim. (CUSMA Articles 5.2 and 5.4)
This guide explains what the document is for. It does not tell you whether your goods qualify — that is the certifier’s determination, not ours.

CUSMA gives goods that count as “originating” under its rules access to preferential rates of duty when they move between Canada, the United States and Mexico. The claim for those rates is based on a certification from the exporter, producer or importer stating that the goods qualify as originating, and on what basis. (CUSMA Article 5.2)
In Canada, CBSA puts it plainly: to claim CUSMA preferential tariff treatment, importers must have the CUSMA certification of origin in their possession at the time of importation. The preferential treatments are the United States Tariff (UST) and the Mexico Tariff (MXT). (CBSA overview)
What does the importer have to do?
When an importer claims CUSMA treatment, the agreement requires it to:
- make a statement in the import documentation, based on a valid certification, that the good qualifies as originating;
- have the certification in its possession when it makes that statement;
- give customs a copy of the certification on request;
- promptly correct the import documents and pay any duties owing if it has reason to believe the certification is based on incorrect information.
The agreement says an importer who promptly makes that correction and pays is not to be penalized for the incorrect statement. (CUSMA Article 5.4)
In Canada, CBSA notes that an importer who falsely declares that it holds proof of origin, or claims preferential treatment on a false declaration, contravenes section 153 of the Customs Act and is liable to sanctions under section 160. (CBSA D11-4-2)
Can customs check a certificate of origin?
The importing country’s customs administration can verify a claim, by written request or questionnaire to the importer, exporter or producer, or by a visit to the exporter’s or producer’s premises. (CUSMA Article 5.9) That is why the signed statement on every certification says the certifier “assume[s] responsibility for proving such representations”, and why the agreement requires records to be kept.
What if the certificate has a mistake?
Customs is not to reject a certification for minor errors or discrepancies that do not create doubts about the correctness of the import documents. If a certification is illegible, defective on its face, or not completed according to the chapter, the importer gets at least five working days to provide a corrected copy. (CUSMA Article 5.7) A certification with all nine data elements present, from the start, avoids that exchange.
When is a certificate of origin not required?
The agreement lets each country waive the requirement for low-value importations: a certification is not required if the value does not exceed US$1,000, or any higher amount the importing country sets. It also allows waivers, but not for a series of importations arranged to get around the rules. (CUSMA Article 5.5)
Canada’s threshold is higher. CBSA does not require a certification of origin where the value for duty does not exceed CAD$3,300, with conditions. The importer must still keep records showing the goods meet the rules of origin, and those shipments can still be verified. (CBSA overview; CBSA D11-4-2) For shipments into the United States or Mexico, check with that country’s customs administration.
What if you didn’t have it at the border?
CBSA says that when CUSMA came into force it extended the time to claim CUSMA preferential tariff treatment after the fact: importers have four years from the date the goods were accounted for, rather than one year. (CBSA overview) Talk to a customs broker about how that applies to a specific entry.
Does the exporter have to provide one?
The agreement does not force an exporter or producer to complete a certification for anyone. (CUSMA Article 5.3.4) But a buyer who wants to claim CUSMA treatment needs a certification in hand (outside the low-value exception above), and if the exporter or producer will not provide one, the buyer can only rely on certifying the goods itself, on the basis of its own information and documents. (CUSMA Articles 5.3.3 and 5.4)
