Mexico has signed a US-led pledge against state-backed overproduction in cars and batteries, siding with Washington ahead of a trade review.
Mexico has joined the United States and 13 other economies in a pledge to tackle car overcapacity and similar overproduction. The Office of the US Trade Representative (USTR), Washington’s trade negotiating office, announced the signatories on Wednesday, 7 October.
For US readers, it matters because Mexico is the largest source of US goods imports and a major base for American carmakers. It also aligns Mexico with a core US priority before the 2027 review of the USMCA, the North American trade pact.
What Mexico Signed
The text is a joint ministerial statement on structural excess capacity and production, published by USTR. It says trade ministers discussed the issue at the G20 trade meeting in Milwaukee, Wisconsin, on 30 September and 1 October.
The signatories are Argentina, Australia, Canada, the European Union, France, Germany, India and Italy. Japan, South Korea, Mexico, Poland, Türkiye, the United Kingdom and the United States complete the list.
Other G20 members, among them Brazil, China, Indonesia, Russia and Saudi Arabia, did not sign. The statement does not name any country as a source of excess capacity.
The ministers named five sectors of concern: cars and electric vehicles, batteries, chemicals, foundational semiconductors and solar panels. They pledged to work in new sector platforms, starting with those five.
The statement calls on all countries to end “non-market policies and practices” that distort markets. Jamieson Greer, the US Trade Representative, said the problem would “cripple domestic industries” if left unchecked.
Senior officials of the signatories met on the sidelines of the OECD Trade Committee to begin the work, USTR said.
Why Car Overcapacity Matters to Mexico
Cars top the list, and that is where Mexico has already acted alone. A decree in Mexico’s official gazette on 29 December 2025 set a 50% tariff on imported passenger cars, including electric ones.
The rate applies to countries without a trade agreement with Mexico, which includes China, and took effect on 1 January 2026. Expansión, a Mexican business magazine, reported that the car tariff rose from 20%.
The new statement adds a group frame to such national steps. It says individual efforts work better if concerned countries “cooperate, share information, and take complementary action.”
Economy Secretary Marcelo Ebrard, Mexico’s trade minister, attended the Milwaukee meeting. From Milwaukee, he told a virtual news conference that Mexico coordinates steel overcapacity talks at the OECD, the daily El Economista reported.
Ebrard said tracing where steel is made comes first. “If you cannot identify that, it makes no sense to talk about controlling overcapacity,” he said.
The USMCA Review Backdrop
The signing comes as Washington prepares the next review of the USMCA. On 2 October, USTR opened public comments for the 2027 joint review, with a deadline of Tuesday, 12 January 2027.
On 1 July, USTR said the US did not agree to renew the pact in its current form; it remains in force. El Economista, citing the Bank of Mexico, reported on Tuesday that annual reviews would follow.
Mexico is itself one of 16 economies in a US probe into excess capacity, opened by USTR on 11 March. The probe falls under Section 301, a US trade law that can lead to tariffs.
Trade flows show why Mexico is careful. Its exports to the US rose 18.3% to US$419.3 billion from January to August, Census Bureau data cited by El Economista show.
Mexico’s share of US goods imports reached a record 17.4% in that period. China’s share fell to 7.6% from 9.5% a year earlier.
What It Means for You
For investors in US carmakers with Mexican plants, such as GM and Ford, the pledge points to continued shielding from subsidised imports. It does not add any new duty on its own.
For importers and shoppers, nothing changes yet. The statement sets no tariff, quota or deadline beyond technical talks before December.
For anyone tracking the USMCA, Mexico is backing an issue the US made a key priority of its G20 presidency. Public comments to USTR on the review close on 12 January 2027.
What Is Not Known
It is not known what the new sector platforms will do, or when. The statement commits signatories to explore “complementary” actions but names no measures.
It is also unclear whether Mexico will extend its tariff approach to batteries, chemicals or solar panels. The statement does not say how each signatory will act at home.
It is not known whether signing will ease Mexico’s position in the Section 301 probe. USTR’s 7 October release does not mention that investigation.
What Comes Next
Officials are due to meet at technical level before December 2026 to draft terms of reference and share data. The group has invited other countries, inside and outside the OECD, to join.
USTR has said it will publish the date of a public hearing on the USMCA review later. The pledge itself changes no tariff today.
