Dear Ambassador Greer,
On behalf of the undersigned associations and organizations, we commend you and your team for running a transparent and inclusive hearing last fall ahead of this year’s 2026 review of the United States-Mexico-Canada Agreement (USMCA).
At the hearing, officials heard unanimous agreement on the significance of USMCA’s rules-based framework and how critical the agreement is to U.S. competitiveness and export success. This broad-based support was underscored in a December 1, 2025, letter to you from more than 500 U.S. national, state, and local organizations.
Reflecting this broad consensus, we write to convey our strong support for extending USMCA and urge USTR’s sustained and meaningful engagement with U.S. business, manufacturing, and agricultural stakeholders throughout the review and until the agreement is renewed for a full 16-year term.
We share the Administration’s objective of a more secure, resilient, and prosperous United States. As the United States’ largest export markets and primary sources of indispensable inputs, Mexico and Canada are foundational to our economic strength and resilience. Consequently, modifications to USMCA’s rules or substantive new proposals have the potential to reshape American competitiveness at home and abroad.
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.
We stand ready to work constructively with USTR toward a positive outcome that extends the USMCA, ensures the agreement’s full implementation, resolves irritants, and restores the predictability and certainty in North American trade that will enable businesses to accelerate their long-term supply chain and investment decisions while avoiding undue cost pressures.
We strongly support concurrent efforts to resolve tariff and non-tariff barriers and to ensure existing USMCA commitments are fully implemented and adhered to. Maintaining duty-free treatment for USMCA-compliant goods throughout this process is an indispensable prerequisite for North American stability. To strengthen the U.S. manufacturing and industrial base, we urge the Administration to avoid imposing any new duties on Canada or Mexico and to restore duty-free trade.
We remain committed to strengthening these vital North American partnerships, committed to this process, and committed to a renewed and truly trilateral USMCA.
Sincerely,
