Trump Wants Half of Every North American Vehicle Made in U.S., Reuters Reports

North America’s auto industry was built around the idea that a vehicle could be assembled in one country from parts made across all three. The Trump administration now wants to redraw that map. Reuters reports that U.S. negotiators have proposed requiring vehicles seeking preferential treatment under the U.S.-Mexico-Canada Agreement to contain 82% North American value, including at least 50% produced in the United States.

That distinction matters: the proposal is not literally a rule that half of each vehicle must be physically assembled on American soil. It is a U.S.-specific content requirement measured by value. Even so, it would represent a dramatic change for automakers, parts suppliers and communities whose factories have operated as one regional production system for decades. With the 2026 trade review beginning, the demand has become one of the clearest tests of whether North American manufacturing remains integrated—or becomes increasingly divided by national borders.

What the 50% Demand Actually Means

Under the proposal described by Reuters, a car or light truck would need 82% regional content to receive the most favourable treatment available under a revised trade pact. Within that total, at least 50% of the vehicle’s value would have to come specifically from the United States. The calculation could include qualifying parts, materials and production activity, but Reuters reported that the precise formula had not yet been publicly explained. That uncertainty is important because a vehicle’s “content” is an accounting measure, not a simple count of components.

The proposal was presented during U.S.-Mexico negotiations, with Canada left outside that round of talks. Reuters also reported that the version discussed did not provide a clear way to count Canadian content toward the new U.S.-specific threshold. For a Canadian engine plant, stamping operation or battery supplier, that omission could be more consequential than the rise from 75% to 82%. A part made in Ontario could still be North American, yet do little to help an automaker satisfy a rule requiring half of the vehicle’s value to originate in the United States.

Why This Would Be a Major Break From Today’s Rules

CUSMA, known as USMCA in the United States, already contains detailed automotive rules of origin. Passenger vehicles and light trucks generally need 75% North American regional value content to qualify for preferential treatment. The agreement also includes labour-value rules requiring 40% of a passenger vehicle and 45% of a light truck to be produced in qualifying high-wage facilities, along with separate requirements covering steel, aluminum and important vehicle components.

Those rules were designed to encourage production within the three-country region rather than in lower-cost markets elsewhere. The Trump administration’s proposal would go further by creating a national requirement inside a regional agreement. That is the central shift. The existing system treats qualifying Canadian, Mexican and American production as parts of one North American pool. A 50% U.S.-specific floor would rank those contributions differently, giving automakers a stronger incentive to replace Canadian or Mexican sourcing with American production even when the existing supplier is already operating inside the free-trade zone.

Why Washington Is Pushing for More U.S. Content

The administration has framed the proposal as a way to reduce trade deficits, strengthen American supply chains and reverse the decline of U.S. manufacturing. Reuters reported that U.S. and Mexican officials broadly agree that the region must address falling U.S. content in vehicles, growing use of Asian components and concerns that goods from outside North America could gain preferential access through transshipment or limited processing. The disagreement is less about whether supply chains should be secure than about where the new production should be located.

For Trump, automotive manufacturing also carries unusual political and economic weight. Assembly plants, engine factories and parts operations support networks of logistics firms, tool-and-die shops and local service businesses. A stricter content rule offers a visible promise: more factories, investment and paycheques inside the United States. The harder question is whether the policy would create enough new American capacity to offset the higher costs and disruption caused by shifting work away from established facilities elsewhere in North America. Moving production on paper is much easier than recreating a mature supplier network in practice.

Canada Has Far More at Stake Than Vehicle Exports

Canada produced more than 1.3 million vehicles in 2024, while its automotive sector contributed $16.8 billion to national GDP. The industry directly employed more than 125,000 people and indirectly supported roughly 427,000 additional jobs, according to federal figures. Automotive trade with the United States totalled approximately $152 billion that year, showing why a change in content rules would reach well beyond assembly lines in Windsor, Oshawa, Oakville, Alliston and Cambridge.

More than 90% of Canadian-made vehicles and about 60% of Canadian-made auto parts are exported to the United States. That dependence turns a technical trade formula into a question about the future of entire communities. A transmission plant does not quickly find a replacement market, and a smaller supplier built around one automaker’s specifications cannot easily redirect its output overseas. Even factories that remain open could face lower volumes if manufacturers decide Canadian content makes it harder to meet the proposed U.S. threshold. The risk is not necessarily an immediate shutdown; it is the gradual loss of new models, tooling contracts and future investment.

Mexico’s Role Makes the Equation Even More Complicated

Mexico is a major global vehicle-production hub and an export platform closely connected to the U.S. market. Its plants assemble vehicles for American, European and Asian brands, while suppliers produce wiring systems, electronics, seats, engines and other components used across the continent. Lower production costs have helped attract investment, but Mexico’s value to automakers also comes from manufacturing scale, transportation links and decades of supplier development. Replacing that network would require much more than relocating final assembly.

The supply chain is not a neat path from one factory to another. Canadian officials have said that vehicles and their components can cross the Canada-U.S. border seven to nine times before final completion. Similar back-and-forth trade connects American and Mexican plants. A component may be formed in one country, machined in another and installed elsewhere. A rule that rewards U.S. value more heavily could force companies to trace and reorganize each stage. That may produce more American sourcing, but it could also weaken the efficiency that has allowed North American factories to compete with production systems in Europe and Asia.

Automakers Would Face Three Difficult Choices

If the proposal becomes policy, manufacturers would broadly have three options: shift sourcing and production into the United States, continue existing supply arrangements and pay the applicable tariff, or change where certain models are built and sold. None is simple. New factories require years of planning, large capital commitments and reliable access to workers, land, energy and suppliers. Paying tariffs may be cheaper for some lower-volume models, while high-volume pickup trucks and sport utility vehicles could justify deeper supply-chain changes.

The current rules have already altered corporate decisions. The U.S. International Trade Commission found that manufacturers reported sourcing changes made specifically to comply with USMCA requirements, including 19 changes involving engines. It also found that most compliance-related sourcing changes increased production costs. Major automakers including General Motors, Ford, Toyota and Tesla have urged the administration to extend the trade pact, arguing that it is important to American auto production. Their position reflects a basic industry reality: U.S. factories often depend on Canadian and Mexican inputs, just as Canadian and Mexican plants depend on American components.

Consumers Could Pay Part of the Bill

Stricter content rules can support domestic parts production, but they do not make the underlying costs disappear. The U.S. International Trade Commission concluded that the existing USMCA auto rules increased activity among American parts and materials producers while slightly reducing several performance measures for U.S. light-vehicle manufacturers. Its modelling also found a slight increase in average U.S. vehicle prices, while its industry survey showed that most sourcing changes made to satisfy the rules raised production costs.

A 50% U.S.-specific requirement would be more demanding than the existing regional structure, so the direction of the pressure is easier to identify than its exact size. Automakers could absorb some expenses, negotiate lower prices from suppliers, remove features or pass increases to buyers. Dealers could then face a familiar problem: higher monthly payments tend to reduce demand, particularly among households already extending loan terms to afford a new vehicle. The impact would vary by model because a truck assembled in Michigan with a heavily American supply chain may be much closer to compliance than a crossover assembled in Mexico from components sourced across several continents.

The Proposal Is Also Leverage in a Larger Trade Fight

The auto demand is arriving as the three countries enter the six-year review built into CUSMA. Reuters reported that the Trump administration is expected to decline an immediate 16-year extension on July 1, beginning annual reviews and leaving the agreement scheduled to expire in 2036 unless the countries later reach a deal. That does not end free trade immediately, but it creates a long period in which investment decisions may be made under a cloud of uncertainty.

Washington is negotiating formally with Mexico while Canada has, so far, been kept outside those rounds. That structure gives the United States leverage to develop terms with one partner and later present them to the other. Canada can resist a U.S.-specific content rule, seek recognition for its integrated high-wage production or offer concessions elsewhere in the trade relationship. The outcome will determine more than tariff treatment. It will signal whether the next era of North American manufacturing is based on shared regional scale or a competition in which each country tries to pull factories, parts contracts and investment away from its neighbours.
