Commerce Secretary Lutnick’s resistance to cutting the 25 percent auto and 50 percent metals tariffs has stalled a bilateral deal Mexico City believed was close, complicating the USMCA review calendar
WASHINGTON, OCTOBER 19, 2026
A bilateral tariff agreement that Mexican officials described as weeks away has run into opposition from inside the American cabinet, according to reporting that circulated through the weekend, leaving the largest trading relationship in North America without a settlement and pushing an already crowded USMCA review calendar further toward the end of the year.
The obstacle, as described in a Wall Street Journal account relayed by Mexican outlets on October 16 and 17, is Commerce Secretary Howard Lutnick. The reporting holds that Lutnick has resisted meaningful reductions in the two tariff lines Mexico cares most about: the 25 percent Section 232 duty on Mexican automobiles and the 50 percent duty on steel, aluminum and the finished goods made from them. Both programs are administered by the Commerce Department. Officials on both sides of the border have publicly denied that the talks have stalled.
The denials have not quieted the story, in part because Mexican Economy Minister Marcelo Ebrard spent Friday, October 16, telling the Chamber of Deputies that a reduction remains likely. He said Mexico would “surely achieve” lower tariffs on steel and cars “in the coming weeks or months,” and that discussions continue daily. He also said that Lutnick had never told him directly that he opposed lowering the duties.
Background: how the rates got here
The two tariff programs at the center of the dispute were built separately and have converged on Mexico by different routes.
The automotive duty originates in the Section 232 national security investigation into automobiles and automotive parts, an authority first exercised in this policy cycle in 2025 and progressively broadened since. The 25 percent rate on Mexican vehicles applies alongside a regional-content mechanism that reduces the effective burden for producers who can document qualifying North American inputs. That mechanism is why Ebrard can accurately describe the sector’s average payment as below 10 percent while the headline rate reads 25.
The metals duty has a longer history and a steeper trajectory. Section 232 tariffs on steel and aluminum, originally set at 25 and 10 percent respectively in the previous decade, were raised to 50 percent in this cycle and extended to a growing list of derivative products. A June 2026 proclamation further adjusted the aluminum, steel and copper programs, and the Bureau of Industry and Security proposed in August to expand coverage to additional downstream goods. The practical effect for Mexico is that a 50 percent rate now attaches not only to primary metal but to a wide range of manufactures containing it.
A third element shapes the backdrop without being formally part of the talks. The President said on August 24 that Section 232 tariffs on cars, trucks, parts and steel would rise to 50 percent on January 1, 2027. No implementing detail has been published, and the statement was made in the context of the breakdown with Canada rather than the Mexican negotiation. But it establishes a deadline of sorts. A Mexican deal concluded before year end locks in relief ahead of a scheduled escalation; a deal that slips past January 1 negotiates against a higher baseline.
## What Mexico is asking for
Mexico’s central demand is a ceiling. Mexican negotiators want no automaker shipping from Mexico to pay more than 15 percent, the rate the United States applies to South Korean vehicles. The framing is deliberate: it casts the request not as a concession but as parity with an Asian competitor that does not share a border, a continental supply chain or a ratified trade agreement with the United States.
Mexican press accounts differ on the detail. Expansión has reported that Mexico wants to preserve the existing model-by-model discount tied to regional content, applying the 15 percent cap on top of it. El Universal has reported a simpler cut from 25 percent to 15 percent regardless of regional content. The two structures produce materially different outcomes for individual assembly plants, and no deal text has been published.
Ebrard has made a point of noting that the headline rate overstates what Mexican exporters actually pay. Regional-content treatment, he told lawmakers, already keeps the automotive sector’s average payment well below 10 percent. He has put the share of Mexican exports entering the United States duty free at between 82 and 85 percent, and the average effective tariff on Mexican exports at roughly 3 to 3.2 percent.
Independent modelling broadly supports the shape of that claim while complicating the comfort it offers. Global Trade Alert’s US tariff estimates put the modelled average applied rate on Mexican goods at about 6.6 percent as of October 19, against roughly 503 billion dollars of 2024 American imports from Mexico. The gap between that figure and Ebrard’s is a question of methodology and weighting rather than a dispute about direction.
Where the pain actually sits
The country-level average is the least useful number in this negotiation, and the modelling itself carries an explicit warning to that effect. Tariff treatment for a USMCA partner is bimodal: goods that qualify under the agreement’s rules of origin largely enter free, and goods that do not are exposed to the full Section 232 and emergency tariff stack. Averaging the two produces a figure that describes no actual shipment.
The chapter detail shows where the money is. Chapter 87, vehicles, accounts for about 27.2 percent of American imports from Mexico by value, roughly 136.6 billion dollars in 2024, at a modelled average of 11.5 percent. Chapter 84, machinery, is another 21 percent at about 6.6 percent average. Chapter 85, electrical equipment, is 17.3 percent of trade at roughly 3.7 percent.
Within vehicles, the individual lines carry the weight. Passenger cars with spark-ignition engines above 1,500cc, the single largest automotive line at about 26.1 billion dollars, are modelled at 14.3 percent. Goods vehicles are near 13 percent. A second passenger car line of about 12.3 billion dollars sits near 12.9 percent. Each of these figures reflects the base schedule plus Section 232, emergency and Section 301 layers combined.
Those are the numbers a 15 percent cap would be measured against, and they explain why the cap matters less as a headline than as a floor-and-ceiling structure. If the average Mexican vehicle already clears near 13 or 14 percent after regional-content adjustment, a flat 15 percent cap applied without that adjustment could in principle raise costs for the best-qualified producers while lowering them for the worst. That is the ambiguity the two Mexican press accounts have failed to resolve, and it is not a drafting technicality. It determines which plants win.
What Mexico has already put on the table
Mexico has not come empty-handed. The government agreed to suspend for five years its own 10 percent tariff on imported parts and components used in vehicle assembly, a concession aimed directly at the economics of cross-border manufacturing. The measure lowers input costs for assembly operations in Mexico, many of which are owned by American and American-allied manufacturers, and it removes an irritant that American negotiators had raised repeatedly.
Mexican officials have also made clear that tariff relief is their top trade priority, ahead of the procedural questions surrounding the agreement’s review. That ordering is itself a negotiating position: it signals that Mexico is prepared to be flexible on process in exchange for movement on rates.
The cabinet split
The reporting describes a division inside the American side that is unusual mainly for being visible. Trade Representative Jamieson Greer leads the negotiations with Mexico. Lutnick does not, but the tariffs at issue are administered by his department and were imposed on national security grounds, which gives Commerce both institutional standing and a stake in the outcome. The Journal account describes tension between the two officials.
Lutnick’s reported position rests on domestic industry warnings that tariff cuts would harm American producers and cause layoffs. That argument has particular force in steel and aluminum, where the 50 percent rate has been credited by domestic producers with supporting utilization rates and new investment, and where any reduction for a neighboring producer with lower energy and labor costs is read as a direct competitive threat.
The Journal noted that this is the second occasion on which Lutnick has disrupted advanced negotiations with a North American partner, a reference understood in both capitals to point at Canada, where talks collapsed in August and where 50 percent tariffs on roughly 20 billion dollars of Canadian goods took effect on August 22.
Ebrard has pressed the point directly. He raised tariffs with Lutnick at a G20 innovation meeting earlier in the cycle, and Mexican accounts of that encounter describe it as pointed rather than productive.
The Canada comparison
Mexican negotiators have watched the Canadian experience closely, and the comparison informs both their urgency and their caution.
Talks between Washington and Ottawa broke down in August. The Canadian prime minister suspended negotiations, 50 percent American tariffs on roughly 20 billion dollars of Canadian goods took effect on August 22, and Canada published a retaliation list of 874 tariff lines covering about 27.6 billion dollars of American imports, effective September 8. The administration followed with further measures in September, including import restrictions and changes to the scope of tariffs imposed under Section 338, a rarely used authority that permits duties of up to 50 percent and that applies regardless of whether goods qualify under USMCA.
The Trade Representative confirmed subsequently that no talks with Canada were underway. The episode demonstrated two things that Mexico City has internalized. The first is that the American side is willing to let a North American negotiation fail. The second is that the Section 338 authority exists and can be applied to a USMCA partner without regard to the agreement’s own tariff commitments, which means that qualifying under the rules of origin is not, by itself, protection.
That second point is the reason Mexican officials have been careful to keep the tone cooperative even while pressing publicly for relief. Ebrard’s statement that Lutnick never told him directly of any opposition reads, in that light, less as a factual correction than as a decision not to personalize the dispute.
## The USMCA calendar
The bilateral talks do not sit in isolation. The United States-Mexico-Canada Agreement is under review, and the Office of the United States Trade Representative moved the process to its next stage in early October, publishing a request for public comments in the Federal Register on October 5 ahead of the 2027 joint review. The Small Business Administration’s Office of Advocacy flagged the comment solicitation to its constituency on October 15.
The administration decided earlier in the cycle against seeking a straightforward renewal of the agreement, opting instead for an annual review process. That choice converted what was designed as a periodic confirmation into a recurring negotiation, and it is the reason the bilateral tariff talks and the review calendar have become entangled. Finalizing a bilateral deal would, in the Mexican reading, clear the way for substantive discussion of the agreement’s renewal.
Ebrard has said a fourth round of USMCA talks must take place before the end of 2026, though no date has been set. Market expectations for a formal extension this year are low. The prediction market Polymarket priced a formal 2026 USMCA extension at 8.5 percent as of 3:30 a.m. Eastern on October 17, though the market is thin and addresses the pact rather than the steel and automotive tariffs at the center of the bilateral talks.
Stakeholder positions
American automakers occupy an awkward position. Most of the vehicles entering the United States from Mexico are built by companies headquartered in the United States, Japan, Korea or Germany, and the tariff is therefore substantially a tax that American manufacturers pay on their own production. Industry groups have supported relief while avoiding public criticism of the administration, a posture that has characterized the sector’s approach to tariff policy since 2025.
Domestic steel and aluminum producers have taken the opposite line with considerably less restraint. Their argument is that the 50 percent rate is working, that capacity utilization and investment have responded, and that carving out a low-cost neighbor would reopen the import channel the measure was designed to close. The expansion of Section 232 coverage to additional derivative products, proposed by the Bureau of Industry and Security in August with comments due August 27, reflects the same view: that the program’s weakness is leakage through downstream goods rather than excessive stringency.
Mexican industry has been more unified. The automotive cluster across Guanajuato, Querétaro, Nuevo León and Coahuila is deeply integrated with American production, and firms on both sides of the border have made the same argument to both governments: that components cross the frontier multiple times before final assembly, and that a tariff applied at each crossing compounds in a way that no single rate expresses.
The derivative-product problem
Running underneath the headline negotiation is a technical question that will shape outcomes regardless of what rate the two governments settle on: which goods count as covered.
The Section 232 metals programs apply to primary steel and aluminum and to a list of derivative products that has expanded repeatedly. Each expansion captures goods that were previously importable at ordinary rates, and each expansion is announced through a Federal Register process that many importers do not monitor. The August proposal from the Bureau of Industry and Security, with comments due August 27, continued that pattern.
For Mexican exporters the derivative list is more consequential than the headline rate, because Mexico’s shipments to the United States are concentrated in manufactured goods rather than primary metal. A furniture component, an electrical enclosure or a vehicle part containing steel can fall inside or outside the list depending on classification decisions that are not always intuitive and that have, in practice, varied.
The adjustment made earlier in 2026 to apply duties to the full customs value of certain derivative articles, rather than only to the metal content, compounded the effect. A product with modest steel content but a high finished value can carry a duty burden out of proportion to the metal it contains. Importers who classified under the earlier content-based approach and have not revisited their entries since are exposed.
This is also where a bilateral deal could prove narrower than it appears. An agreement that reduces headline rates on steel and automobiles while leaving the derivative-inclusion process untouched would deliver less relief than the headline suggests, because Commerce would retain the ability to expand coverage administratively. Mexican negotiators are reported to be aware of this. Whether the point has been conceded in the draft is unknown.
## Economic impact
The scale of the relationship is what makes the standoff consequential. American imports from Mexico ran to roughly 503 billion dollars in 2024, making Mexico the largest single source of American goods imports. A change of ten percentage points in the automotive rate, applied across 136 billion dollars of vehicle trade, moves numbers large enough to register in national accounts.
For American consumers, the automotive tariff is among the most directly felt of the measures imposed since 2025. Vehicle prices respond to input costs with a lag, and the 25 percent rate has been in place long enough for that lag to have run. Relief at 15 percent would ease pressure on a category that occupies an outsized place in household budgets and in inflation expectations.
For American manufacturers of steel-intensive goods, the calculation runs the other way. Firms buying Mexican steel inputs at a 50 percent duty have been absorbing costs that their foreign competitors do not face, and some have responded by moving final assembly offshore, the outcome the tariff was intended to prevent. The derivative-product expansion proposed in August was aimed at that leakage, and it illustrates the structural difficulty: each extension of coverage creates a new margin at which production can relocate.
The uncertainty itself carries a cost that neither side’s public arguments capture well. Capital expenditure decisions in automotive assembly run on five to seven year horizons. A tariff rate that may be 25 percent or 15 percent depending on an unresolved cabinet dispute is not a number a plant investment committee can underwrite. Several North American programs have reportedly been deferred rather than cancelled, which registers as nothing in trade statistics and as a great deal in industrial capacity five years out.
What importers should do now
The practical guidance for American importers is specific.
Rules of origin documentation is the highest-value work available. Because treatment is bimodal, the difference between a qualifying and a non-qualifying shipment is the difference between near-zero and a double-digit rate. Firms that have not recently audited their regional value content calculations, their tracing of non-originating materials and their supplier certifications are leaving money on the table under the tariffs currently in force, regardless of how the negotiation ends.
Scenario planning should be built around the structure of a cap rather than its headline. Importers should model both versions reported in the Mexican press: a 15 percent ceiling applied on top of existing regional-content discounts, and a flat 15 percent replacing them. Firms with strong regional content may find the second version worse than the status quo.
Comment participation in the USMCA review is open and underused. The Federal Register notice published October 5 is the formal channel through which importers can put sectoral detail on the record, and the record is what the review process will draw on. Small and mid-sized importers in particular have historically been underrepresented in these dockets relative to their exposure.
Finally, firms should watch the Commerce Department rather than only the Trade Representative. The reporting this week makes the point that the tariffs at issue are Commerce instruments, and that the department’s view carries weight independent of the negotiating track. Section 232 inclusion decisions, derivative-product expansions and exclusion determinations all run through Commerce, and all will continue to move whether or not a bilateral deal is signed.
Outlook
Both governments insist the talks are alive. Ebrard’s public confidence, expressed as recently as Friday, is either a negotiating posture or an accurate reading of where the American interagency process will land, and from outside it is not possible to distinguish the two.
What can be said is that the structural obstacle described in the reporting is real and is not resolved by denial. Section 232 tariffs were imposed on national security grounds, which gives the Commerce Department a defensible basis for resisting reductions that other agencies might trade away for commercial gains. Until that question is settled inside the American cabinet, Mexico’s 15 percent cap remains an ask rather than an offer.
