Mexico's proposed third round of tariffs has not yet landed, but the direction is clear: textiles, apparel fabrics, and garments are again designated as key controlled categories. Combined with two rounds of tariffs already in effect since 2026, China's cost advantage in the Latin American market is being systematically eroded. For export enterprises with profit margins typically between 4% and 8%, this is not a simple tax increase but a prelude to a restructuring of the entire North American supply chain.
Cumulative Tariff Effect: Costs Multiply
In January 2026, Mexico converted temporary tariffs into permanent regulations, imposing 10% to 50% duties on 1,463 tariff lines. Textile rates rose to 25%-35%, garments up to 45%, covering imports worth $52 billion. In April, additional tariffs of 5%-35% were applied to 185 tariff lines, again hitting apparel, footwear, and textile accessories. After two rounds, the comprehensive tax rate for Chinese textiles entering Mexico has become significantly higher than that for other origins.
If the third round materializes, even a modest increase would be a heavy blow to enterprises already near the break-even point. Public industry data show that in 2024, China accounted for over 30% of Mexico's textile and apparel imports, with a large share being low-margin, high-volume basic products. Every percentage point increase in tariffs could directly translate into order losses.
Dual Drivers Behind the Policy: Geopolitics and Domestic Protection
Mexico's move is not an isolated incident. External pressure stems from U.S. concerns over "origin laundering"—Asian textiles transiting through Mexico to enter the North American market duty-free under USMCA. Washington has been pressing Mexico to tighten import management, and Mexico is aligning its trade policy to gain leverage in the annual review of the agreement.
Domestically, the Sheinbaum government's "Plan Mexico" prioritizes import substitution in textiles, with local industry associations calling for stronger restrictions to protect employment. However, Mexico's textile chain is incomplete; many garment factories rely on Chinese fabrics and chemical fiber inputs. Tariffs raise input costs, which also increase production costs for local garment makers—a contradiction that may constrain the policy's extremes.
Industrial Transmission: From Customs to Orders
Beyond tariffs, Mexico has intensified origin verification, cracking down on false declarations. Higher inspection rates increase risks of port detention and cargo seizure, raising logistics time and capital costs. Past reliance on transshipment or gray customs channels has been blocked, increasing compliance costs.
For buyers, tariff uncertainty directly alters ordering decisions. Many Mexican garment factories source Chinese greige fabrics for processing. When fabric tariffs rise, they may shift to alternatives from Vietnam or India, or demand price concessions from Chinese suppliers. This means Chinese exporters face not only profit compression but also the risk of losing market share.
