CBP and CBSA verify USMCA preference claims through audits and verification requests. Documentation must support: rules-of-origin qualification, Certificate of Origin validity, supporting BOM analysis, and supplier certifications. Failed verification results in retroactive duty plus AMPS (Canada) or Section 1592 (U.S.) penalties.
This guide covers USMCA Verification – Responding to CBP and CBSA Audits. USMCA (called CUSMA in Canada) provides preferential tariff treatment for goods qualifying under specific rules of origin among the United States, Mexico, and Canada.
In 2026, USMCA-qualifying goods are also exempt from Section 122 – making qualification work directly value-creative for cross-border trade.
Verification triggers
Random selection, risk targeting (high-volume USMCA preference claims, anomalous patterns), or industry-wide verification campaigns.
Documentation expected
Certificate of Origin, BOM analysis, supplier certifications, RVC calculations, plant-level wage records (for autos), origin documentation for traced components.
Response timeline
Both agencies set short response windows (30 days typical). Extensions available for complex requests.
Failed verification consequences
Retroactive duty (full MFN plus Section 122 plus Section 232/301 where applicable), interest, and penalties. Pattern of failures triggers broader audit.
Frequently asked questions
How does USMCA differ from NAFTA?
USMCA replaced NAFTA in July 2020. Key differences include stricter auto rules of origin (75% RVC vs 62.5%), Labor Value Content rules, and updated rules for digital trade, IP, and dispute settlement.
When does USMCA come up for review?
The 2026 review is now narrowly scoped to U.S.-Mexico production and non-market inputs. The agreement continues; specific provisions may be updated.
Are USMCA goods exempt from Section 122?
Yes. USMCA-qualifying goods are exempt from the Section 122 surcharge. This is the central commercial advantage in 2026.
How do I know if my product qualifies?
USMCA qualification depends on rules of origin specific to your HS classification. We run RVC stress-tests as a fixed-fee engagement.
What does USMCA qualification work cost?
Per-product RVC stress-test: $4,500-$8,500. Multi-product engagements priced by SKU count.
