The fastest-growing fault line in North American trade is no longer confined to cars, steel or aluminum. Artificial-intelligence infrastructure is moving into the centre of the debate as Washington presses Mexico for tighter rules governing the origin of chips, servers and other AI hardware entering the United States.
The discussions arrive at an unusually fractured moment. Mexico and the United States are actively negotiating changes around supply chains and market access, while Canada-U.S. trade negotiations have remained suspended since August. The proposed AI measures are not a continental AI safety regime. Instead, they would use trade rules to encourage more North American production and make it harder for goods containing large amounts of foreign content—particularly content Washington associates with China—to qualify for preferential treatment. That could reshape an AI supply chain that has expanded far faster than many policymakers expected.
Washington Is Turning AI Hardware Into a North American Trade Issue
The immediate development is a U.S. effort to convince Mexico to accept tighter rules for artificial-intelligence hardware moving across the southern border. The Wall Street Journal reported on September 16 that American negotiators want limits on how much non-North American content can be used in products such as servers and chips while still benefiting from favourable trade treatment. The proposal is aimed primarily at reducing opportunities for Chinese companies or Chinese-origin components to reach the American market through production or assembly in Mexico. No final regional-content percentage or compliance timetable has publicly been agreed.
That makes this less a debate about how AI models should behave and more a debate about where the machines powering them are built. A server rack headed from a Mexican manufacturing plant to a U.S. data centre may contain processors, boards, memory, power systems and other components sourced from several countries. Under tougher origin requirements, manufacturers could have to document more of that supply chain and potentially replace some overseas components with North American alternatives. Washington is effectively asking whether the trade rules written for an earlier manufacturing era can be adapted to the enormous build-out of AI infrastructure now underway.
Mexico’s AI-Hardware Boom Explains Why Washington Is Paying Attention
Mexico has quietly become one of the most important assembly and export platforms supporting America’s AI infrastructure expansion. According to the Wall Street Journal, AI-related hardware exports from Mexico to the United States reached roughly $83 billion during the first half of 2026, surpassing automobiles as Mexico’s leading export category to the U.S. That is a remarkable shift for a trade relationship traditionally associated with cars, pickup trucks, appliances and agricultural products.
The trend did not appear overnight. Federal Reserve researchers reported earlier in 2026 that U.S. demand for AI-related goods had driven large increases in exports from Mexico, Taiwan and Vietnam. Mexico stood out because its AI-related exports were overwhelmingly headed to the United States. Brookings separately noted that Mexican exports of automatic data-processing equipment—including servers, motherboards and data-centre components—had already exceeded $79 billion over the 12 months ending in November 2025. For companies building hyperscale data centres, Mexico offers proximity to the U.S. market and an established manufacturing base. For Washington, however, that same success raises a strategic question: how much of the value inside those products actually originates within North America?
The Auto Industry Provides Washington’s Template
Rules of origin are hardly new to North American manufacturers. USMCA already uses them extensively to determine whether products qualify for preferential trade treatment, with the automotive sector providing the clearest example. Passenger vehicles and light trucks generally must meet a 75% North American regional-value-content requirement under the agreement. Manufacturers consequently spend significant time tracing where engines, transmissions, electronics and other components originate before certifying a vehicle.
The emerging AI proposal would apply a similar philosophy to a very different industry. Instead of asking how much of a vehicle was produced inside North America, trade officials could increasingly ask where the processors, printed circuit boards, servers and related electronics inside AI systems came from. That would potentially give North American component suppliers a stronger commercial incentive while making sourcing decisions more complicated for Mexican manufacturers dependent on Asian supply networks. Importantly, Washington has not publicly established an AI-hardware threshold matching the automotive industry’s 75% rule. The comparison is therefore about the policy mechanism rather than a confirmed percentage. What is clear is that origin rules have become a broader U.S. industrial-policy tool, not merely an automotive technicality.
China Is at the Centre of the U.S. Concern, but the Supply Chain Is Global
Washington has increasingly framed USMCA negotiations around preventing countries outside the agreement from receiving its benefits without making enough of the product inside North America. U.S. Trade Representative statements throughout 2026 repeatedly referred to reducing dependence on outside suppliers, strengthening regional manufacturing and addressing what the U.S. calls “free-riding” by non-parties. Negotiators began discussing strengthened rules of origin and economic security months before AI hardware emerged publicly as the latest target.
The challenge is that modern AI equipment comes from deeply international supply chains. Federal Reserve researchers found that Mexico’s growing AI manufacturing industry imports important technology inputs from abroad, with Taiwan playing a significant role in the wider AI supply chain. Washington’s concern is particularly focused on China, but rewriting origin requirements can affect companies with suppliers across Asia, not only Chinese manufacturers. Taiwanese contract manufacturers, electronics producers and component suppliers with Mexican operations could therefore face additional documentation or sourcing requirements. That distinction matters because restricting Chinese circumvention and requiring substantially more North American content are related but not identical policies. The broader the rule becomes, the more companies could have to redesign procurement networks that developed around global specialization.
Mexico Has Reasons to Cooperate—and Reasons to Resist
Mexico enters these talks with substantial incentives to reach an accommodation with Washington. More than 80% of Mexican exports go to the United States, according to Reuters, and President Claudia Sheinbaum’s government has been seeking relief from American tariffs affecting automobiles, steel and aluminum. Reuters reported on September 11 that the two governments were moving quickly toward a possible interim trade arrangement, with Chinese investment and automotive content among the American demands being discussed. U.S. and Mexican officials had already committed to a fourth bilateral negotiating round in Washington during September.
Mexico has nevertheless resisted measures that could weaken the advantages that made USMCA attractive in the first place. In the auto negotiations, Mexican officials have opposed explicit requirements for a fixed share of U.S.-made content, even while showing willingness to discuss ways to increase regional production. Similar tension surrounds AI hardware. Mexico can strengthen enforcement against tariff circumvention without necessarily accepting every U.S. proposal governing where manufacturers buy their components. The country has also imposed higher tariffs on numerous imports from economies with which it lacks trade agreements, including China, and Economy Minister Marcelo Ebrard said affected Chinese imports fell sharply during the first five months of 2026. Mexico is therefore already adjusting its trade posture, but it still wants room to develop its own manufacturing strategy.
Canada Is Watching From a Very Different Negotiating Position
The contrast with Canada is becoming increasingly difficult to ignore. Prime Minister Mark Carney suspended Canada-U.S. trade negotiations on August 21 after saying last-minute American demands made the emerging arrangement uneconomic and unacceptable to Ottawa. Canada recalled its negotiating team, and the dispute subsequently broadened into retaliatory tariffs and additional trade restrictions. By September 15, Carney was still describing renewed engagement as something that could happen when conditions for a mutually beneficial partnership returned rather than announcing a resumption of formal negotiations.
Mexico, meanwhile, has remained at the table. Reuters reported that the failure of the Canadian negotiations increased the urgency surrounding the U.S.-Mexico discussions. Mexican officials have emphasized continued dialogue while pursuing tariff relief, and U.S. officials have used those bilateral meetings to address manufacturing, investment screening, rules of origin and economic security. That does not mean Canada has left USMCA or that Mexico can rewrite the trilateral agreement alone. It does mean that important ideas about the future architecture of North American trade are currently being developed through an active U.S.-Mexico channel while the equivalent Canada-U.S. channel is suspended. For Canadian businesses, that sequencing matters even before any rules become legally binding.
USMCA Has Not Disappeared, but Its Review Has Changed the Negotiating Dynamic
The legal position is more stable than the political headlines sometimes suggest. USMCA entered into force in 2020, and its first mandatory six-year joint review took place on July 1, 2026. The United States declined to approve a new 16-year extension in the agreement’s current form. That decision did not terminate USMCA. The agreement remains in force, with additional annual reviews now required unless the three governments eventually agree to extend it.
What has changed is the negotiating environment around it. U.S. and Mexican officials began bilateral discussions months before the formal July review, covering economic security, industrial rules of origin, steel, aluminum, autos, labour and agriculture. USTR has repeatedly said it wants the benefits of the agreement to accrue primarily to its three member countries. Artificial-intelligence hardware now fits naturally into that agenda because it combines manufacturing, technological leadership and national-security concerns. Yet any major permanent change to USMCA itself would ultimately involve all three parties. Bilateral discussions can produce tariff arrangements, regulatory cooperation and negotiating templates, but Canada remains part of the continental agreement. The unresolved question is whether Washington and Mexico are effectively designing proposals that Ottawa will later be asked to consider.
The AI Fight Could Eventually Pull Canada Back Into the Conversation
Canada has significant reasons to pay attention even while broader trade negotiations remain suspended. Ottawa is trying to expand domestic AI infrastructure and reduce strategic dependence on foreign technology. On September 15, Carney highlighted new Canadian investment commitments involving AI companies and data-centre infrastructure while describing AI as one of the strategic capabilities around which Canada wants greater autonomy. That domestic push means rules governing North American AI hardware could eventually intersect with Canadian ambitions in semiconductors, electricity, data centres, critical minerals and advanced manufacturing.
The unanswered questions are substantial. Washington has not announced a final threshold for North American content in AI equipment. Mexico has not publicly accepted the reported proposal. Canada is not currently participating in the same active bilateral negotiating process, and the three countries have not announced a trilateral AI-hardware agreement. What is visible, however, is a shift in what North American trade policy now covers. Twenty years ago, arguments about continental production centred heavily on cars. In 2026, the same debate is moving toward the servers and chips supporting artificial intelligence. If those products become subject to stricter regional-content rules, Canada will eventually have to decide how closely its own AI industrial strategy should be tied to a more tightly controlled North American technology supply chain.
