Mexico’s rapidly expanding inventory of Chinese-made heavy trucks has emerged as a significant impediment in its ongoing efforts to secure relief from US tariffs. Washington is increasingly pressing for assurances that its southern neighbor is not inadvertently becoming a conduit for Chinese manufacturers to access the North American market, according to sources familiar with the matter.
The value of Mexican imports of Chinese trucks has surged dramatically, ballooning more than sevenfold over a six-year period. This substantial increase has ignited concerns among both local Mexican manufacturers and US authorities. Concurrently, the number of Chinese truck companies operating within Mexico has also seen a significant rise, now totaling approximately 23. This development creates fresh tension as Mexican negotiators seek to alleviate US trade barriers that have adversely impacted one of the country’s most integrated export industries.
USMCA Review Highlights Geopolitical Tensions
This dispute strikes at the core of the US-Mexico-Canada Agreement (USMCA) review process, specifically questioning Mexico’s ability to convince Washington of its alignment against China while simultaneously safeguarding its own domestic manufacturers from inexpensive imports and maintaining crucial access to its largest export market. American negotiators are particularly worried that Chinese vehicles and components could enter Mexico and subsequently benefit from North American supply chains, complicating Mexico’s pursuit of relief from US tariffs on medium- and heavy-duty trucks and parts.
Mexican truck manufacturers are advocating for a two-pronged solution: they are requesting higher domestic tariffs on Chinese vehicles, alongside a US approach that recognizes Mexican-made trucks as an integral part of the North American industrial base, rather than perceiving them as a competitive threat. Existing tariffs for heavy trucks imported into Mexico currently range from 5% to 20%, but manufacturers are seeking duties of as much as 50% on heavy vehicles from countries lacking free-trade agreements with Mexico, primarily China.
Bilateral Talks and Economic Pressures
The issue is expected to be a central topic in a third round of bilateral talks between Mexico and the US, commencing Tuesday in Mexico City. The US has indicated that the trade pact will not be renewed in its current form, though it remains in force as the three nations continue negotiations over various disputes, including automobiles, steel, supply chains, and China’s role in North America. US Trade Representative Jamieson Greer is slated to attend these discussions. Greer’s office stated that issues to be discussed will include “steel and aluminum and derivative products, automobiles, economic security, labor, agriculture and electronic payment services.” The Mexican Economy Ministry, responsible for USMCA negotiations, declined to comment on the matter.
Washington imposed 25% tariffs on medium- and heavy-duty trucks and parts in November 2025. While USMCA-qualifying vehicles may see this levy applied only to the value of non-US content, according to USTR’s 2026 autos report, the broader trade environment remains challenging. Mexico’s heavy-vehicle industry is already under considerable pressure. Official data indicates that output fell 13% year-on-year in the first half of 2026, with foreign shipments declining by 14.5%. The US absorbed a significant 92.3% of these sales, underscoring the sector’s acute vulnerability to shifts in American trade policy.
Domestically, Mexican manufacturers contend that Chinese rivals are undercutting them with low-cost vehicles, often with opaque reporting practices. They have specifically argued that some Chinese units are entering Mexico at declared customs values significantly below market prices, thereby distorting competition and diminishing the appeal of locally produced trucks. Notable Chinese manufacturers and brands with documented heavy-truck or bus operations in Mexico include Yutong Bus Co., BYD Co., and FAW.
The ongoing negotiations represent a critical juncture for Mexico, as it navigates the complex interplay of its trade relationships with both the United States and China, seeking to protect its vital export industries while addressing Washington’s deepening concerns over North American economic security and supply chain integrity.
