The U.S. Chamber joined 68 other business organizations in a letter calling on USTR to conduct “structured, substantive, and ongoing engagement with U.S. business, manufacturing, and agricultural stakeholders” during the U.S.-Mexico-Canada Agreement (USMCA) joint review intended to conclude on July 1. The letter reads in part:
“U.S. production and supply chains are built on trillions in long-term investment, which have been refined over years to be highly efficient to comply with USMCA’s rigorous framework. Material changes to USMCA requirements or rules of origin could lead to multi-year supply chain disruptions at significant cost to companies invested in America, raise consumer prices, and erode North American competitiveness.
“It is therefore imperative that proposals, including rules of origin, be clear, implementable, recognize manufacturing and production realities, and minimize trade disruptions. To this end, we respectfully request structured,
substantive, and ongoing engagement with U.S. business, manufacturing, and agricultural stakeholders on any proposals.”
In the Fervors of July: As required under the agreement, the first joint review of the USMCA will take place on July 1, 2026, to determine whether there is tripartite concurrence to extend the agreement for another 16 years, modify it, or conduct annual reviews. In the meantime, the administration is engaged in bilateral negotiations with Mexico and Canada. While none of the three parties appear interested in a broad renegotiation the agreement’s 34 chapters, Greer recently said the U.S. may seek to “tack on” separate protocols for Canada and Mexico “to fix some of the gaps.”
Chamber Advocacy: The U.S. Chamber continues to underscore the importance of strengthening the USMCA by ensuring full compliance from all three parties, preserving the agreement’s trilateral character, and holding fast to the basic institutional framework of the pact. This effort includes outreach to the administration as well as key congressional committees and the offices of lawmakers representing states with significant economic ties to the USMCA.
In parallel, the Chamber’s U.S.-Mexico Economic Council and U.S.-Canada Business Initiative are holding regular dialogues with senior government officials in both countries. These interactions highlight the deep integration of North American economies and business communities, while also encouraging both governments to proactively address investment‑climate concerns ahead of the 2026 review.
