US Chassis Makers Win Trade Case Against Mexico, Thailand, Vietnam Imports
Event summary
- USITC ruled May 20, 2026 that Mexican, Thai, and Vietnamese chassis imports injured domestic producers
- Commerce will impose antidumping duties up to 186.84% and countervailing duties up to 76.91%
- Orders follow 2025 petition by US Chassis Manufacturers Coalition
- Duties will compound existing Section 232 steel tariffs on chassis imports
- Coalition to monitor for duty evasion and circumvention
The big picture
This decision marks the latest chapter in a decade-long trade battle for US chassis manufacturers, following similar cases against Chinese imports. The high duty rates signal growing protectionism in US manufacturing sectors dependent on steel inputs. The compounding of duties with existing Section 232 tariffs creates significant cost pressures for chassis importers and their customers in the logistics industry.
