Intro
For the past several years, importers have been navigating a trade environment shaped by tariffs, shifting sourcing strategies, and growing pressure to build more resilient supply chains. Now, another major milestone is approaching: the 2026 review of the United States-Mexico-Canada Agreement (USMCA).
While the review is not automatically a renegotiation, it introduces uncertainty around the future of North American trade—and uncertainty is something importers can’t afford to ignore.
Here’s what businesses should be watching.
What is the 2026 USMCA review?
USMCA includes a built-in six-year review process. In 2026, the United States, Mexico, and Canada will evaluate how the agreement is performing and determine whether to extend it for another 16 years. If the countries do not agree to an extension, the agreement remains in effect but enters annual reviews until its scheduled expiration in 2036.
Although the review is intended to assess the agreement, many trade experts expect broader discussions around manufacturing competitiveness, rules of origin, labor standards, and regional supply chain security.
Why importers should pay attention now
Even before any formal changes are announced, uncertainty influences business decisions.
Many companies are already reassessing where they source products, how they structure supplier relationships, and whether their current import strategy will remain cost-effective over the next several years.
Waiting until policy changes are finalized often leaves businesses reacting instead of planning.d.
Nearshoring remains a strategic conversation
Mexico continues to play a growing role in North American manufacturing and distribution. Companies looking to reduce transit times, diversify away from Asia, or improve supply chain resilience continue to explore nearshoring opportunities.
At the same time, the USMCA review may place additional attention on regional manufacturing requirements and rules of origin. Businesses that currently rely on complex global supply chains should evaluate whether their sourcing strategy would continue to qualify for USMCA benefits if enforcement becomes stricter. Recent discussions have included stronger origin requirements and increased scrutiny of transshipment through Mexico.
Documentation matters more than ever
No matter what comes out of the 2026 USMCA review, customs compliance will remain a critical part of cross-border trade. Companies that maintain complete, organized documentation are generally better positioned to respond to audits, support preferential duty claims, and adapt if enforcement priorities change.
Country-of-origin documentation
Country of origin determines whether a product may qualify for USMCA preferential treatment, but it also plays a role in broader customs compliance. Importers should maintain accurate origin records for every product they import and ensure those records are supported by documentation from their suppliers. Incomplete or inconsistent origin records can create delays during customs reviews and make it more difficult to substantiate duty claims.
Supplier certifications
USMCA qualification depends on more than simply sourcing from Canada or Mexico. Importers should ensure they have current supplier certifications and supporting documentation demonstrating that products satisfy the agreement’s rules of origin. Reviewing these certifications regularly helps identify gaps before they become compliance issues.
Bills of materials and rules of origin
Many products qualify for USMCA based on where their components originate and how they’re manufactured. Bills of materials should clearly support applicable rules of origin and provide sufficient detail to demonstrate compliance if Customs requests additional information. As sourcing strategies evolve, these records should evolve as well.
Customs classifications
Accurate tariff classification remains one of the foundations of customs compliance. Product classifications influence duty rates, admissibility requirements, and eligibility for preferential treatment. As product lines change or regulations evolve, importers should periodically review classifications to confirm they remain accurate.
Audit trails for duty claims
Preferential treatment under USMCA should always be supported by clear documentation. Importers should be able to demonstrate how a product qualified, when supporting documentation was received, and how decisions were made throughout the import process. Well-maintained audit trails make it significantly easier to respond to Customs inquiries while reducing compliance risk.
Don’t assume today’s strategy will work tomorrow
Many businesses are asking whether they should diversify suppliers, increase sourcing from Mexico, or redesign portions of their supply chain.
There isn’t a universal answer.
The right strategy depends on your products, tariff exposure, supplier network, and long-term growth plans. What is clear is that businesses with greater supply chain visibility will be better positioned to adapt as trade policy evolves.
