At the first joint review of the United States-Mexico-Canada Agreement on July 1, 2026, the United States did not agree to extend it for a new 16-year term. The agreement governs nearly $2 trillion in annual trade and remains in force, but the three countries now hold a joint review every year. Unless all three confirm an extension, it terminates on July 1, 2036.
Companies that moved production to Mexico to avoid Section 301 duties on Chinese goods face heightened scrutiny. CBP is actively investigating transshipment and substantial transformation claims. Documentation gaps that used to be routine now carry real legal exposure.
Section 301, Section 232, and AD/CVD duties can stack on the same shipment. If you're not auditing every layer, you're almost certainly overpaying, or under-declaring and exposing yourself to penalties.

If you're manufacturing in or sourcing from Mexico, you need a broker who understands USMCA preferential treatment claims, rules of origin requirements, and country-of-origin compliance. Most generalist brokers file entries but don't verify whether your USMCA claims will survive a CBP audit.
USMCA rules of origin determine whether a product qualifies for preferential duty rates when imported from Mexico or Canada. Each product has specific requirements — tariff shift rules, regional value content thresholds, or both. False or unsupported preferential claims carry penalties and retroactive duty assessments.
Potentially, but only if your products meet USMCA substantial transformation requirements. Simply assembling Chinese components in Mexico does not eliminate Section 301 liability. CBP is actively investigating transshipment schemes and weak transformation claims. Your origin documentation must be defensible.

The agreement remains in force, and the three countries now hold a joint review every year. Unless all three confirm an extension, it terminates on July 1, 2036. Importers should keep auditing their current USMCA claims and follow each annual review.
