The United States-Mexico-Canada Agreement (USMCA) allows qualifying goods to enter duty-free on MFN base rates, and USMCA-qualifying goods are also exempt from the Section 122 tariff (per the April 2, 2026 proclamation). But USMCA does NOT eliminate Section 232 tariffs (50% on articles wholly of steel/aluminum, 25% on derivative products after the April 6, 2026 restructuring). And many products fail to qualify because they don't meet the rules of origin. This playbook walks through the qualification process with real examples, common mistakes, and the exact steps to determine if your product qualifies.
What USMCA Actually Eliminates (and What It Doesn't)
USMCA eliminates MFN base duties on qualifying goods from Canada and Mexico. MFN base duties are the standard tariff rates in the Harmonized Tariff Schedule — typically 0-20% depending on the product. USMCA-qualifying (CUSMA-qualifying) goods are also EXEMPT from the Section 122 tariff under the April 2, 2026 proclamation. However, USMCA does NOT eliminate: Section 232 tariffs (after the April 6, 2026 restructuring, 50% on articles wholly of steel/aluminum and 25% on derivative steel/aluminum products, plus 25% on autos — these are national security tariffs, not trade agreement tariffs), or AD/CVD duties. So for steel/aluminum, the rate is 50% Section 232 on wholly-of articles or 25% Section 232 on the full customs value of derivatives (Section 122 does not stack on the metal content), regardless of USMCA status.
The Three Rules of Origin Tests
To qualify for USMCA, your product must meet at least one of three tests. Test 1 — Wholly Obtained: The product is entirely grown, produced, or manufactured in North America (US, Canada, or Mexico) using only North American materials. Examples: Canadian maple syrup, Mexican avocados, US-grown wheat. Test 2 — Tariff Shift: The product undergoes sufficient transformation in North America. The HTS classification of the finished product must differ from the HTS classification of any non-North American inputs at a specified level (chapter, heading, or subheading). Example: Chinese fabric (HTS Chapter 52) sewn into a finished shirt (HTS Chapter 62) in Mexico qualifies for tariff shift. Test 3 — Regional Value Content (RVC): A specified percentage of the product's value must originate in North America. The threshold varies by product — automobiles require 75% RVC, while many manufactured goods require 50-60%.
Example: Auto Parts from Mexico — Qualifying vs Non-Qualifying
Qualifying scenario: A brake assembly manufactured in Mexico. Mexican-made brake pads (40% of value), US-made calipers (25% of value), Mexican labor and overhead (20% of value), Chinese steel (15% of value). Regional Value Content: 85% North American. USMCA auto parts threshold: 75%. Result: QUALIFIES. Duty: 0% — USMCA-qualifying goods are exempt from Section 122 and the MFN base duty is eliminated (assuming the part is not Section 232-covered). Non-qualifying scenario: The same brake assembly but with Chinese brake pads (50%), Chinese calipers (20%), Mexican assembly only (15%), Chinese steel (15%). Regional Value Content: 15% North American. Result: DOES NOT QUALIFY. Duty: MFN base rate + 10% Section 122; if the part is Section 232-covered it is instead 25% Section 232 (Section 122 does not stack on Section 232 auto parts). The difference can be 10-25% in additional duties.
Example: Food Products from Canada
Canadian food exports generally qualify easily if the product is wholly grown or raised in Canada. Canadian beef, maple syrup, canola oil, pulses, and seafood — all wholly obtained in Canada — qualify for USMCA and enter duty-free (USMCA-qualifying goods are exempt from both the MFN base duty and the Section 122 tariff). But processed foods using non-North American ingredients may not qualify. Example: A Canadian company packages Thai shrimp in Canada. The shrimp originates in Thailand, and repackaging alone does not constitute sufficient transformation. This product does NOT qualify for USMCA despite being exported from Canada. The shrimp would face MFN duty + Section 122 + potentially AD duties (Thailand shrimp has an active AD order).
Certificate of Origin Requirements
Unlike NAFTA, which required a specific government form, USMCA allows the exporter, producer, or importer to self-certify origin. The certification must include: the certifier's name, title, and contact information; the exporter and producer information; a description of the goods and their HTS classification; the origin criterion met (wholly obtained, tariff shift, or RVC); the certification period (can cover multiple shipments of identical goods up to 12 months); and a signature and date. Keep the certification and all supporting documentation for at least 5 years. CBP can audit USMCA claims and demand proof of qualification.
Common Mistakes That Disqualify Products
Mistake 1: Assuming any product from Canada or Mexico automatically qualifies. It doesn't — the product must meet rules of origin, which means substantial North American content or transformation. Mistake 2: Transshipment. Routing Chinese goods through Mexico does not make them Mexican. The product must undergo substantial transformation, not just pass through. Mistake 3: Failing to meet the product-specific rule. Each HTS code has its own origin rule — some require tariff shift at the chapter level, others at the heading or subheading level. Check the USMCA Annex 4-B for your specific product. Mistake 4: Not maintaining documentation. CBP audits are becoming more frequent. Without proper records, you lose the USMCA preference and owe back duties plus penalties. Mistake 5: Forgetting that Section 232 still applies. While USMCA-qualifying goods are exempt from the Section 122 tariff (per the April 2, 2026 proclamation), Section 232 metal and auto tariffs are NOT covered by USMCA and apply regardless of qualification.
What Happens If You Don't Qualify
If your product from Canada or Mexico does not qualify for USMCA, it is treated as a standard import. You pay: MFN base duty (varies by product, typically 0-20%) + Section 122 (10%) + Section 232 if applicable (50% on steel/aluminum, 25% on autos — Section 122 does not stack on the metal content of a Section 232 article). For most manufactured goods, failing to qualify adds 5-20% in MFN base duties on top of Section 122. For auto parts, the penalty is steeper — the 25% Section 232 auto tariff applies in full to non-qualifying parts. Work with a customs broker to classify your product and verify USMCA eligibility before relying on preferential rates.
Key Takeaway
USMCA can save you 5-20% on MFN base duties for qualifying goods from Canada and Mexico, and qualifying goods are also exempt from Section 122 — but USMCA does not eliminate Section 232 tariffs. Qualifying requires meeting specific rules of origin — not just shipping from a USMCA country. Use the decision tree above and check the product-specific rules in USMCA Annex 4-B for your HTS code. When in doubt, consult a customs broker.
