USMCA certificate of origin: the 9 data elements, blanket period and thresholds
Under the USMCA there is no official certificate of origin form. To claim preferential duty, the importer needs a certification of origin completed by the importer, exporter or producer, in any format, that contains nine minimum data elements. It can be on the invoice, can cover identical goods shipped over up to 12 months and is valid for four years.

How a USMCA claim works
The importer claims preference at entry. In the US this is done on the entry summary by putting "S" or "S+" before the HTSUS subheading of each originating good, and the certification must be in the importer's possession when the claim is made. CBP may ask for a copy, and the importer is responsible for the truth of the claim.
A certification can be completed by the importer, exporter or producer. An exporter that is not the producer may rely on the producer's written representation that the good is originating. It must be signed and dated by an authorised person; electronic and digital signatures are accepted. The US accepts certifications in English, French or Spanish; for Canada the CBSA lists English or French.
The nine minimum data elements (Annex 5-A)
- 1. Certifier type: whether the certifier is the exporter, producer or importer
- 2. Certifier: name, title, address (including country), telephone number and email address
- 3. Exporter: name, address, email and phone, if different from the certifier (not needed if a producer certifies and does not know the exporter)
- 4. Producer: name, address, email and phone, if different from the certifier or exporter; "Various" or an attached list for several producers, or "Available upon request by the importing authorities" for confidentiality
- 5. Importer: name, address, email and phone, if known
- 6. Description and HS tariff classification of the good to the 6-digit level, plus the invoice number for a single shipment if known
- 7. Origin criteria under which the good qualifies, as set out in Article 4.2
- 8. Blanket period, if the certification covers multiple shipments of identical goods (up to 12 months)
- 9. Authorized signature and date, with the statement "I certify that the goods described in this document qualify as originating and the information contained in this document is true and accurate" and the rest of the Annex 5-A text
Thresholds, records and late claims
The agreement lets each country skip the certification for low-value imports of at least USD 1,000. The US does not require a copy for non-commercial imports or commercial imports whose originating goods are worth USD 2,500 or less, and Canada sets CAD 3,300 for value for duty; both can still ask for one if shipments are split to avoid the rule. Mexico had up to three years and six months after entry into force to accept certifications completed by the importer.
US importers must keep the certification and supporting records for at least five years from importation, and Canada asks for six years. If no claim was made at entry, a US importer can claim the preference and a refund within one year after the date of importation. Even when a good qualifies, other US duties can still apply; see Triplicate's note on US import duties.
Step by step
- Confirm the good's HS code and the USMCA rule of origin (origin criterion) it meets.
- Decide who certifies: the importer, exporter or producer, based on who has the origin information.
- Write the nine data elements on the invoice or a separate document, add the certification statement, sign and date it.
- Use a blanket period of up to 12 months for repeated identical goods, and give the importer the certification before entry.
- Keep the origin records (five years in the US, six in Canada) and correct any claim promptly if the information turns out wrong.
Documents you usually need
- USMCA certification of origin (nine data elements, any format)
- Commercial invoice
- Producer's written representation, if the exporter is not the producer
- Bill of materials and cost records supporting the origin criterion
- Transit and transshipment records, if the goods passed through a non-party
Common problems and how to avoid them
What to do: Explain that USMCA has no prescribed form; provide the nine data elements and the certification statement on the invoice or a separate document.
What to do: Add the HS classification to at least 6 digits so it matches the importer's tariff line.
What to do: Limit the blanket period to 12 months and to identical goods; issue a new certification for new products.
What to do: Supply a corrected certification; the agreement gives the importer not less than five working days to do so.

Common questions
Is there an official USMCA certificate of origin form?
No. Any format is accepted, including the commercial invoice, as long as it has the nine minimum data elements and the certification statement. CBP Form 434 is no longer in use.
Who can sign a USMCA certification of origin?
The importer, exporter or producer of the good. A responsible official or authorised agent with knowledge of the facts signs and dates it, and electronic signatures are accepted.
How long is a USMCA certification valid?
Four years from the date it was completed. A single certification can cover one shipment or identical goods over a blanket period of up to 12 months.
Do I need a certification for a small shipment?
Not for US commercial imports with originating goods worth USD 2,500 or less, or Canadian imports with value for duty up to CAD 3,300, unless shipments are split to avoid the rule. Records proving origin must still be kept.
Can I claim USMCA after the goods have been imported?
Yes. In the US the importer can make a post-importation claim and request a refund within one year after the date of importation.
