USMCA Certificate of Origin: How to Claim Your Section 122 Exemption Before July 2026

# USMCA Certificate of Origin: How to Claim Your Section 122 Exemption Before July 2026

The Section 122 universal import surcharge is sitting at 15% through July 24, 2026. For most importers that is a hard cost passed straight into landed price. But goods that qualify under USMCA — the United States–Mexico–Canada Agreement — are exempt. Zero Section 122. Zero base MFN. Zero reciprocal layer.

The catch is documentation. CBP has been tightening USMCA certification audits since the Section 122 carve-out was published in February 2026, and a Certificate of Origin missing any of the nine required data elements is grounds for retroactive duty assessment plus a 10% record-keeping penalty. With roughly 80 days left on the Section 122 window, importers from Canada and Mexico should treat their certifications as the highest-leverage paperwork on the desk.

Here is what your Certificate of Origin must include, the rules-of-origin tests your goods have to pass, and the verification triggers CBP is using right now.

Why USMCA Documentation Matters More in 2026 Than It Did in 2025

USMCA has been in force since July 1, 2020, but for most of that period the difference between claiming preferential treatment and not claiming it was the base MFN rate — typically 0% to 6.5% on the categories most importers move across the Mexico and Canada borders. That made USMCA paperwork a nice-to-have for some shippers and an outright skip for others.

That math broke on February 24, 2026. The Section 122 surcharge took effect at 10% and was raised to 15% two days earlier than its effective date. USMCA-qualifying goods are explicitly carved out of Section 122 in the February 24 proclamation. Goods from Canada and Mexico that do not qualify under USMCA are subject to the full 15%.

So the gap between a properly certified shipment and a non-certified shipment from the same origin is no longer 3% — it is 15% to 21% depending on the product's MFN rate. On a $250,000 shipment of furniture from Mexico, the difference is roughly $37,500 in duty. That is the math driving the renewed CBP attention.

The Nine Required Data Elements

USMCA does not require a specific form. The certification can be a standalone PDF, a statement on the commercial invoice, or an electronic record — but it must contain all nine of the data elements specified in Annex 5-A of the agreement. CBP rejects certifications that are missing any element, and the rejection triggers a duty re-assessment at the non-USMCA rate.

The nine required elements:

1. Importer, Exporter, or Producer Certification of Origin — clearly identify which party is signing. Any of the three can certify, but the role must be stated. 2. Certifier's name, title, address (including country), telephone, and email. 3. Exporter's name, address (including country), telephone, and email — if different from the certifier. 4. Producer's name, address (including country), telephone, and email — if different from the certifier and exporter. "Various" is acceptable when there are multiple producers. 5. Importer's name, address, and country — if known. 6. Description of the goods — sufficient to relate them to the goods covered by the certification, plus the HTS classification to at least the six-digit (subheading) level. 7. Origin criterion — A, B, C, or D, indicating which USMCA rule of origin the goods qualify under. 8. Blanket period — if the certification covers multiple shipments of identical goods, specify the dates (maximum 12 months). 9. Authorized signature, certification date, and the required certification statement — the exact statement is published in the Annex 5-A and must be included verbatim.

The two elements that get rejected most often are the HTS code (importers commonly list the 10-digit US classification when the certifier should list the agreed-upon six-digit subheading) and the origin criterion (importers select B when the goods actually qualify only under C, or vice versa).

The Four Origin Criteria Explained

A. Wholly Obtained or Produced: Goods entirely grown, mined, or produced in one or more USMCA countries. Cattle raised in Mexico, lumber milled in Canada from Canadian trees, and avocados grown in Mexico all qualify under Criterion A.

B. Produced from Originating Materials Only: Every input is itself USMCA-originating. A Mexican-made cabinet built entirely from Mexican-cut wood, Mexican-made hinges, and Mexican-finished hardware qualifies under Criterion B even though it has been transformed in production.

C. Tariff Shift and/or Regional Value Content: This is the criterion that covers most manufactured goods. Non-originating inputs are allowed if (i) they undergo a tariff classification change specified in the product-specific rules of origin, or (ii) the finished good meets a regional value content (RVC) threshold — typically 60% transaction value or 50% net cost, depending on the product and the calculation method.

D. Specifically Listed Goods: A small set of goods, primarily certain auto parts and aerospace components, qualify only when produced from materials of HTS chapters specifically listed in the rules of origin annex. Most importers will never use Criterion D.

If your goods are manufactured in Mexico or Canada from any meaningful share of non-USMCA inputs (Chinese steel, Asian electronics components, etc.), Criterion C is the test. Get the product-specific rule of origin from Annex 4-B of the USMCA text, and run the tariff shift or RVC calculation yourself — do not rely on a supplier's word that the goods qualify.

The Auto Industry Has Stricter Rules

Passenger vehicles, light trucks, and core auto parts have their own rules of origin in USMCA Article 4.4, and they are stricter than the general Criterion C tests:

- Regional Value Content must reach 75% under the net cost method (up from 62.5% under NAFTA), phased in to its current level. - Labor Value Content (LVC) requires that 40% of passenger vehicle value (45% for light trucks) be produced by workers earning at least USD 16/hour. - Steel and Aluminum Purchasing: 70% of the steel and aluminum a vehicle producer buys must be North American.

Auto parts importers should be running the LVC and steel/aluminum tests every model year — these have been the single largest source of CBP USMCA verifications in 2025 and 2026.

How CBP Is Verifying USMCA Claims in 2026

CBP's verification authority under USMCA is broader than under NAFTA. Verifications can include:

- Written information requests to the importer, exporter, or producer. - Verification visits to the production facility in Mexico or Canada (with the producer's consent). - Records inspection of the producer's bills of materials, supplier invoices, and labor records.

In 2026, CBP has been issuing significantly more CF-28 Requests for Information targeting USMCA claims, particularly on:

- Furniture and wood products from Mexico — the top-volume USMCA category. - Auto parts from both countries. - Apparel from both countries — including verification that yarns and fabrics meet the yarn-forward rule. - Steel products from Mexico — particularly downstream products that may use Chinese-origin coil.

If you receive a CF-28 on a USMCA claim, you have 30 days to respond with the underlying documentation. Failure to respond — or a response that does not substantiate the claim — results in retroactive duty assessment at the non-USMCA rate, which now includes the 15% Section 122 surcharge on top of base MFN.

The Five-Year Records Rule

Both the importer and the certifier (whether that's the exporter or producer) must keep records supporting the USMCA claim for five years from the date of importation. Required records include:

- The Certification of Origin itself. - Bills of materials and product specifications. - Supplier invoices for all inputs (originating and non-originating). - Production records that link inputs to finished goods. - For RVC calculations: cost accounting records sufficient to verify the calculation. - For LVC and steel/aluminum compliance (auto industry): payroll records and supplier purchasing records.

This is not theoretical. CBP has assessed millions of dollars in retroactive duty on importers who could not produce supporting records — even where the goods almost certainly did qualify — because the documentation was incomplete.

Common Rejection Triggers

Based on CBP rulings and verification outcomes published in 2025 and the first quarter of 2026, the most common reasons USMCA claims are rejected:

1. HTS classification errors on the certification — listing the 10-digit US classification when the certifier should list the six-digit subheading. 2. Wrong origin criterion — selecting Criterion B when the goods contain non-originating inputs (Criterion C territory). 3. Missing certifier identification — the certification doesn't clearly state whether the importer, exporter, or producer is signing. 4. No supporting BOM — the importer cannot produce the bill of materials linking finished goods to originating inputs. 5. RVC method confusion — switching between transaction value and net cost methods in the same audit period without disclosure. 6. Blanket certifications without identical goods — using a single 12-month certification to cover materially different products. 7. Steel and aluminum traceability — for products subject to the auto industry steel/aluminum rule, an inability to trace to North American mill origin.

What to Do This Week

If you are importing from Canada or Mexico and have not audited your USMCA documentation since January 2026, do four things:

1. Pull a recent Certificate of Origin for each major SKU and check it against the nine required data elements. If any are missing, request a corrected certification before the next entry. 2. Confirm the origin criterion for each product line. If you have been claiming Criterion B, verify that no non-originating inputs are entering the supply chain — Criterion B has zero tolerance for non-originating materials. 3. Run a sample RVC calculation on at least one Criterion C product. If you cannot reproduce the supplier's calculation from documents in your file, the documentation is not adequate. 4. Confirm five-year records retention for entries already filed. CBP can verify any entry within five years; an importer's strongest defense is the underlying paperwork.

The Section 122 surcharge is scheduled to expire July 24, 2026, but Treasury has signaled it intends to replace the temporary surcharge with permanent expanded Section 301 and Section 232 coverage. USMCA carve-outs are likely to remain — meaning the value of clean USMCA documentation will not disappear with Section 122.
