USMCA Certificate of Origin: 9 Required Data Elements

If you ship goods between the U.S., Mexico, and Canada and claim duty-free treatment under the United States-Mexico-Canada Agreement (USMCA), the certification of origin you provide must contain nine specific pieces of information. Miss one, and U.S. Customs and Border Protection (CBP) can deny the preferential tariff claim and re-assess the duty at the most-favoured-nation rate.

Unlike the old NAFTA form, USMCA does not prescribe a fixed format. The nine required data elements — listed in Annex 5-A of the agreement — can appear on a commercial invoice, a separate certification document, or any other shipping paper, as long as all nine are present and the description is detailed enough to identify the originating good.

This guide walks through each of the nine elements, what they mean in practice, and what to verify before the July 1, 2026 Joint Review, when the three governments will decide whether to extend the agreement for another 16 years.

What is the USMCA certification of origin?

The USMCA certification of origin is a written or electronic statement, made by the importer, the exporter, or the producer, that a good qualifies for preferential tariff treatment under the agreement. According to USMCA Chapter 5 (Origin Procedures) and Annex 5-A, the certification does not need to follow any prescribed form. It only needs to contain the nine minimum data elements that prove the good is originating and meets the rules of origin in USMCA Chapter 4.

This is the central change from NAFTA. NAFTA required a specific Certificate of Origin form (CBP Form 434). USMCA dropped that form and replaced it with a data-element rule. The certification can sit on the commercial invoice, on a packing list, on a separate sheet of paper, or be transmitted as an electronic record. What matters is that the data is there, that it is accurate, and that the certifier can support the claim if CBP asks.

What are the nine minimum data elements in Annex 5-A?

The nine data elements listed in USMCA Annex 5-A form the basis of any valid certification. Each element answers one specific question — about the goods, the parties, or the certifier — and they must all be present for the certification to be complete. The following list mirrors the order of Annex 5-A.

1. Certifier of the certification of origin. Indicate whether the certifier is the importer, the exporter, or the producer.
2. Certifier details. The certifier's name, title, address (including country), telephone number, and email address.
3. Exporter details. The exporter's name, address (including country), email, and telephone number. If the certifier is the producer and does not know the exporter, this element can be omitted.
4. Producer details. The producer's name, address (including country), email, and telephone number. If the same as the exporter or certifier, the certification may state "Same as exporter" or "Various" with appropriate confidentiality protections.
5. Importer details. The importer's name, address (including country), email, and telephone number, if known.
6. Description and HS classification of the good. A description detailed enough to relate it to the good covered by the certification, together with the Harmonized System tariff classification at the six-digit level.
7. Origin criterion. The preference criterion (A, B, C, or D) under which the good qualifies, as defined in USMCA Article 4.2.
8. Blanket period. If the certification covers multiple shipments of identical goods, the period during which it applies (no longer than twelve months).
9. Authorized signature and date. The certifier signs, certifies that the information is true and accurate, and assumes responsibility for proving the claim if asked.

Who can sign a USMCA certification of origin?

USMCA permits three parties to certify origin: the importer, the exporter, or the producer. This is wider than NAFTA, which restricted certification to the exporter or the producer. The change shifts both responsibility and audit exposure to whichever party signs.

If the producer certifies, the producer must have direct knowledge that the good meets the relevant rule of origin in Chapter 4. If the exporter or the importer certifies without being the producer, that party should obtain a written representation from the producer or have other reliable information to support the claim. CBP, the Canada Border Services Agency, and Mexico's Servicio de Administración Tributaria can each audit the certifier of record under USMCA Article 5.9.

How long is a USMCA certification of origin valid?

A USMCA certification of origin is valid for four years from the date it was signed. For shipments of identical goods, a blanket period of up to twelve months may be used. One certification then covers every qualifying shipment that falls within that twelve-month window, and data element 8 in Annex 5-A captures the period.

After four years, the certification must be re-issued. If material information changes within the validity period — such as the producer, the rule of origin used, or the product description — a new certification should be prepared. According to USMCA Article 5.8, the importer must also retain the certification and supporting records for at least five years from the date of importation.

What happens if a data element is missing?

If CBP finds that a certification is incomplete or that a required data element is missing, it can deny the preferential tariff treatment and assess the most-favoured-nation (MFN) duty rate, along with any applicable Section 301 tariffs and merchandise processing fees. CBP can also issue a CF-28 Request for Information to verify the origin claim. If the response is unsatisfactory, the case can escalate to a CF-29 Notice of Action that formally rate-advances the entry and demands payment of the additional duty.

Repeated or material errors can trigger a more formal origin verification under USMCA Article 5.9, which may include written questionnaires, requests for production records, or visits to the producer's facility. Civil penalties under 19 USC 1592(c) for false claims can reach two times the unpaid duties for negligence, four times for gross negligence, and the domestic value of the goods for fraud. None of these outcomes require the importer to have intended the error — negligence is enough.

How should exporters prepare for the July 2026 Joint Review?

Under Article 34.7 of USMCA, the United States, Mexico, and Canada will begin a joint review of the agreement on July 1, 2026 — the sixth anniversary of entry into force. The three governments will decide whether to extend USMCA for another sixteen years, to 2042; to commit to annual reviews; or to allow the sunset path that would end the agreement in 2036. The Congressional Research Service product R48787 walks through the procedural steps the review will follow.

Regardless of the political outcome, every USMCA certification on file becomes a record that customs authorities may audit during and after the review period. The recommended action, repeated across trade bar and customs advisory practice, is consistent: audit existing certifications now. For each qualifying good, confirm that all nine Annex 5-A elements are present, that the origin criterion is supportable with a bill of materials and any required regional value content calculation, and that any Chinese-origin content has been correctly tracked. Fix gaps before July 1, when verification activity is expected to rise.

USMCA Annex 5-A pre-review checklist

Is the certifier identified as importer, exporter, or producer?
Are the certifier, exporter, producer, and importer details all complete (where applicable)?
Is the description detailed enough to identify the good, with a six-digit HS classification?
Is the origin criterion (A, B, C, or D) named and supportable with documentation?
Is the blanket period (if used) within twelve months?
Is the authorized signature and date present?
Are supporting records — bill of materials, supplier statements, manufacturing records — retained for five years from the date of importation?

USMCA shifted origin certification from a fixed government form to a data-element rule. That made the rule more flexible — and more demanding. The nine elements in Annex 5-A are the floor, not the ceiling. With the July 2026 Joint Review approaching, the certifications signed today are the records the review will inspect tomorrow.
