Background and Context

On Thursday, China’s Ministry of Commerce launched an investigation into new tariffs that Mexico plans to impose on products from countries without existing trade agreements. This move comes as Mexico’s President Claudia Sheinbaum’s administration proposed the maximum tariff allowed by the World Trade Organization (WTO) on 1,463 product classifications across 17 strategic sectors. This initiative is part of Mexico’s 2026 Economic Package, which requires legislative approval in 2025.

Impact and Key Changes

The proposed tariffs will affect $52 billion worth of imports (8.6% of total foreign purchases), and they are part of Mexico’s Program for Protection of Strategic Industries. For instance, the tariffs on imported vehicles will rise to 50%, up from a current range of 15-20%. Meanwhile, tariffs on imported auto parts will increase to a range of 10-50%, from the current 0-35%.

China’s Investigation Details

According to a statement, the Chinese government will conduct this investigation following relevant provisions of China’s Foreign Trade Law and the Ministry of Commerce’s Regulations on Investigating Barriers to Foreign Trade.

  • Product Categories Affected: Specific product categories impacted include automobiles and parts, textiles, clothing, plastics, steel, home appliances, aluminum, toys, furniture, footwear, leather goods, paper and cardboard, motorcycles, and glass.
