How to Fill Out a Certificate of Origin: USMCA and Generic

Key Points

• USMCA requires no prescribed form; instead, the certification must contain nine specific data elements listed in 19 CFR Part 182.
• Only three parties may certify USMCA origin: the importer, the exporter, or the producer of the good.
• A blanket certification may cover multiple shipments of identical or similar goods over a period of up to 12 months; if an entry date falls outside that period, the claim is invalid.
• All supporting records must be retained for five years from the date of certification.
• A generic (non-preferential) certificate of origin, typically issued by a chamber of commerce, serves commercial and letter-of-credit purposes and does not by itself confer a duty preference.

A certificate of origin is the document that tells CBP and foreign customs authorities where a good was made, and in a trade-agreement context it is the foundation of a preferential duty claim. For USMCA, the certification is a self-prepared statement containing nine mandatory data elements rather than a fill-in form. For commercial transactions outside any trade agreement, a generic certificate issued or countersigned by a chamber of commerce satisfies buyers and banks. The links in this article go to the primary documents: the regulations, CBP guidance pages, and the official tariff schedule itself. Read the source.

What a certificate of origin does and when you need one

A certificate of origin serves two distinct functions that are easy to conflate.

• Preferential origin claim. Under a free trade agreement such as USMCA, the certification is the legal basis for claiming a reduced or zero duty rate. CBP may deny the preference, assess the full duty, and impose penalties if the certification is wrong or unsupported.
• Non-preferential (commercial) origin declaration. Many buyers, banks processing letters of credit, and foreign customs authorities require a document showing country of origin even when no duty preference is claimed. This is the generic certificate.

You need a preferential certification whenever you are claiming a trade-agreement rate at entry or filing a post-entry claim for a refund. You need a generic certificate whenever your buyer's contract or a letter of credit requires one.

The USMCA certification: no form required, nine data elements required

Unlike the old NAFTA Certificate of Origin (CBP Form 434), USMCA has no prescribed form. 19 CFR Part 182 and the CBP USMCA Implementation Instructions specify that any document, including a commercial invoice, a letter, or a standalone statement, qualifies as long as it contains the nine minimum data elements. CBP's USMCA guidance page confirms this and provides a sample format for reference.

Using a template is perfectly fine. What is not fine is omitting an element or completing one incorrectly.

Field-by-field guide to each USMCA data element

1. Certifier's name, title, and contact information

Identify the individual signing the certification: full legal name, job title, company name, address, telephone, and email. This is the person who stands behind the claim and whom CBP will contact during a verification.

2. Certifier's capacity

State explicitly whether the certifier is acting as the importer, exporter, or producer of the good. Do not leave this blank or write a vague phrase such as "authorized representative." CBP needs to know which party is making the legal representation and under what knowledge base.

3. Exporter's name and contact information

Provide the full legal name, address, and contact details of the exporter. If the certifier is the exporter, this field is still required; do not simply cross-reference field 1. If the exporter is unknown at the time of certification, note that clearly.

4. Producer's name and contact information

Provide the full legal name, address, and contact details of the producer. When there are multiple producers, you may list each one or use the statement "Available upon request" if you have a confidentiality concern. Leaving this blank entirely is a common error that invites a CBP verification request.

5. Importer's name and contact information

Provide the full legal name, address, and contact details of the importer. If unknown at time of export (for example, when the goods will be sold in transit), note that it is unknown.

6. Description of the good

Describe the good in enough detail that CBP can connect it to the HTS classification and the rule of origin. A description like "parts" is insufficient. A description like "hydraulic pump assemblies used in agricultural equipment" gives a verifier enough context.

7. Six-digit HTS classification

Provide the six-digit Harmonized System (HS) subheading for the good. Use the USITC Harmonized Tariff Schedule to verify the classification. If the tariff-shift rule of origin depends on a chapter or heading change, the six-digit code is the starting point for that analysis. A wrong code means applying the wrong rule of origin, which makes the entire certification defective.

8. Origin criterion

This is the most legally significant field. USMCA defines several origin criteria; you must select and state the one that actually applies to the good. The principal criteria are:

• A, The good is wholly obtained or produced entirely in the USMCA territory.
• B, The good satisfies the applicable tariff classification change, regional value content, or other rule of origin in Annex 4-B of the Agreement.
• C, The good is produced entirely in the USMCA territory exclusively from originating materials.
• D, The good qualifies under the de minimis or other specific provisions.

Stating "B" when the good has not actually undergone the required tariff shift or does not meet the regional value content threshold is a false certification. This is among the leading causes of denied claims and CBP penalty actions.

9. Authorized signature and date

The certification must be signed, physically or electronically, by an authorized representative of the certifying party. The date of the signature is the date of certification, not the shipment date. Both must appear.

Blanket certification period

A single certification may cover multiple shipments of identical or similar goods for a blanket period of up to 12 months. State the start and end date clearly (for example: January 1, 2025 through December 31, 2025). Every entry claiming preference under that certification must have an entry date that falls within the stated period. An entry dated outside the blanket window has no valid supporting document and the preference claim will be denied.

Who may certify and what that means in practice

Only the importer, exporter, or producer may certify USMCA origin. Each has a different knowledge base and a different legal exposure.

• Producer certification is typically the most reliable because the producer performed the manufacturing and has direct knowledge of the inputs, costs, and transformation. A producer certification given to an exporter or importer for their use is called a "producer's statement" or "producer's declaration."
• Exporter certification is common in supply chains where the exporter has obtained a producer's declaration and is vouching for it. The exporter must have a reasonable basis for the claim.
• Importer certification is permissible but shifts the entire evidentiary burden to the importer, who may not have direct access to production records. Importers who self-certify should obtain a written producer's declaration and keep it with the certification file.

Customs brokers and freight forwarders are not listed parties and may not sign a USMCA certification in their own name. They may assist in preparing the document, but the legal certifier must be the importer, exporter, or producer. See the CBP USMCA page for additional guidance on certifier responsibilities.

Record-keeping obligations

Under 19 CFR Part 182, every party who completes or relies on a USMCA certification must retain all records supporting that certification for five years from the date of certification. This includes:

• The signed certification itself
• Bills of materials and cost records supporting the regional value content or tariff-shift analysis
• Supplier declarations or producer statements relied upon
• Any correspondence with CBP related to a verification

CBP may initiate an origin verification at any point within that five-year window. Failure to produce records is treated as a failure to substantiate the claim.

The generic certificate of origin for non-preferential purposes

When no trade-agreement preference is being claimed, a "generic" or "commercial" certificate of origin is still often required. Common scenarios include:

• A letter of credit that requires a certificate of origin as a shipping document
• An import permit in the destination country that requires proof of origin
• A buyer's internal procurement requirement

A generic certificate is typically prepared by the exporter on company letterhead and then submitted to a local chamber of commerce for notarization or countersignature. The chamber verifies the identity of the signatory, not the accuracy of the origin claim; factual responsibility stays with the exporter.

What the generic certificate typically contains

• Exporter name, address, and contact information
• Importer or consignee name and address
• Country of origin of the goods
• Description of the goods, quantity, and value
• Invoice number and date
• Exporter's declaration and signature
• Chamber stamp or countersignature, if required

A generic certificate does not substitute for a USMCA certification and does not by itself entitle the importer to a preferential rate. Conversely, a valid USMCA certification does not eliminate the need for a generic certificate if the buyer's contract independently requires one.

Common mistakes that get a claim denied

Wrong origin criterion

Selecting criterion A (wholly obtained) for a good that contains third-country inputs, or selecting criterion B without running the tariff-shift or regional value content analysis, is a substantive error. CBP verifications frequently find this as the primary defect. If the good does not actually qualify under the stated criterion, the preference will be denied and back duties will be assessed.

Blanket period that does not cover the entry date

A blanket certification valid through June 30 does not cover a July 5 entry. Every entry that claims preference must fall within the stated blanket dates. Customs brokers should cross-check entry dates against the blanket period as a routine pre-entry quality-control step.

Producer who cannot support the rule of origin

When an importer or exporter certifies based on a producer's declaration, and that producer cannot later provide cost records, bills of materials, or supplier declarations to support the tariff-shift or regional value content claim, the certification collapses. The certifier's reliance on the producer does not insulate the importer from liability for the back duties.

Missing or vague data elements

Omitting the certifier's capacity, writing an incomplete product description, or providing a four-digit HTS heading instead of a six-digit subheading are all defects that give CBP grounds to reject the claim outright. CBP may, at its discretion, allow correction, but it is not required to do so.

Certifier lacks authority or knowledge

A purchasing agent who has not reviewed the production records, or an administrative assistant who signs without authorization, creates a certification that cannot be substantiated. The certifier must have actual knowledge of, or a reasonable basis for, the origin claim.

What importers should do

• Before filing a USMCA preference claim, verify that your certification contains all nine required data elements, names the correct origin criterion, and that the entry date falls within the blanket period.
• Obtain a written producer's declaration with supporting cost or bill-of-materials data before self-certifying as an importer; do not certify based solely on a supplier's verbal assurance.
• Retain the signed certification and all supporting records for five years and organize them so they can be produced quickly in the event of a CBP verification.
• For commercial or letter-of-credit purposes, work with your local chamber of commerce to understand their countersignature requirements before the shipment date, since turnaround times vary.
