USMCA Tracing Rules for Auto Components

USMCA tracing rules require auto Tier 1/2 suppliers to trace specific components back through the supply chain to determine origin. Traced materials list (engines, transmissions, axles, etc.) must be qualified separately. Without tracing, the entire material counts as non-originating.

This guide covers USMCA Tracing Rules for Auto Components. 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.

Traced materials list

Engines, transmissions, axles, batteries, body parts, suspensions, and others are listed. Each must trace back to USMCA-qualifying production.

Tracing computation

Each traced component’s origin determines its contribution to the finished vehicle’s RVC. Non-traced foreign components count as non-originating in full.

Supplier certifications support tracing

Tier 2 and Tier 3 suppliers must provide supplier-level certifications to support OEM tracing.

Tracing failure consequences

Without proper tracing documentation, the entire component value counts as non-originating. RVC math fails; vehicle does not qualify.

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.
