USMCA Revamp and Continued Tariffs
U.S. Trade Representative Jamieson Greer announced on 26 May 2026 that tariffs on imports from Canada and Mexico will remain in place while the United States-Mexico-Canada Agreement (USMCA) undergoes its first mandatory review, scheduled for 1 July 2026. Greer said the United States will keep “tariffs as long as we have a giant trade deficit” and will use the review to push for “rules of origin … that enhance U.S. content” and for coordinated external tariffs that limit non-North-American goods entering the region.
Background & Context
The USMCA, which replaced NAFTA on 1 July 2020, contains a 16-year term with a built-in review clause. The Trump administration has pursued a protectionist agenda, reinstating Section 232 steel and aluminum duties and imposing sectoral tariffs on autos, steel, aluminum, copper and wood. The administration frames these measures as necessary for “national security” and for reshoring U.S. manufacturing.
Key Figures & Groups
- Jamieson Greer, U.S. Trade Representative.
- President Donald Trump, U.S. President.
- Mark Carney, Canadian Prime Minister (as cited).
- Claudia Sheinbaum, President of Mexico.
- Greg Stanton, U.S. Representative from Arizona.
- Pete Hoekstra, U.S. Ambassador to Canada.
- Canadian auto-industry representatives and Mexican exporters of automobiles, computers and minerals.
Timeline
- 26 May 2026: Greer speaks at a Council on Foreign Relations event, outlining tariff policy.
- 25-26 May 2026: First formal bilateral talks begin in Mexico City with Mexican officials; Canada has not yet entered negotiations.
- 1 July 2026: USMCA review period opens, triggering a ten-year cycle of annual reviews if the 16-year extension is not secured.
Data & Statistics
- U.S. goods-trade deficit fell >30 % to $202.1 billion in the most recent year, but the deficit with Mexico rose 15 % to $196.9 billion.
- The trade-deficit metric used by the administration has declined 24 % since April 2025.
- Mexico’s April 2026 exports reached $72 billion (up 33 % YoY); 80 % of its imports were intermediate goods for assembly.
- Mexico’s auto sector employs ?800,000 workers; computer-equipment assembly employs ?60,000.
- Canadian steel imports from the United States face a 25 % counter-tariff, despite a domestic shortage of certain grades.
Official Statements & Responses
Greer emphasized that “rules of origin … will be talked about … to enhance U.S. content” and that “external tariff coordination … will reduce Chinese products entering U.S. supply chains through Canada and Mexico.” He added that “for national-security reasons, I want our supply chain sourced from this hemisphere.”
Canada’s Mark Carney called for the United States to lower sectoral tariffs on autos, steel, aluminum, copper and wood in exchange for deeper integration.
Rep. Greg Stanton warned that Trump’s “massive tariffs” threaten the ability to modernize the USMCA.
Ambassador Pete Hoekstra described Canada’s retaliatory measures as “totally unfair” and said the United States will not negotiate tariff relief for alcohol bans.
Criticism & Opposition
Canadian officials view the U.S. stance as retaliatory, noting that Canada has already reduced many counter-tariffs and abandoned its digital services tax. Canadian auto manufacturers anticipate stricter content rules that could raise production costs. Canadian steel producers argue that U.S. counter-tariffs on steel raise costs without strengthening domestic steel capacity. Mexican exporters warn that U.S. tariffs are pushing Mexico’s export profile toward low-value assembly rather than higher-value manufacturing.
On-the-Ground Impacts
Mexico’s export mix has shifted: light-vehicle shipments have stagnated while computer-equipment exports surged 144 % in 2025, reflecting a move toward products less affected by U.S. tariffs. Canadian coffee exporters report a 40 % drop in U.S. sales after the 2025 “fentanyl” tariffs, despite a Supreme Court ruling that later limited the duties.
Conflicting Reports & Gaps
Greer asserts that tariffs will remain until the trade deficit is resolved, while Canadian officials expect the United States to lower sectoral tariffs as part of any USMCA renewal. No specific timetable for tariff adjustments has been disclosed, and the precise content of the forthcoming “rules of origin” revisions remains undefined.

What’s Next
The formal USMCA review begins on 1 July 2026, with bilateral talks slated to continue with Mexico and, later, Canada. Negotiators are expected to discuss tighter rules of origin, coordinated external tariffs, and sector-specific content requirements. The outcome will determine whether preferential tariff treatment persists or if the United States moves toward a longer series of annual reviews.
