Customs
$32.37 duties hit some chassis imports from Mexico
Thailand and Vietnam have their own rates, including much higher margins for some producers. U.S. Customs will collect cash deposits on covered entries, which can raise landed costs quickly.
New antidumping orders put fresh border costs on certain chassis and subassemblies from Mexico, Thailand and Vietnam. For importers, the immediate impact is at customs, but the price pressure can spread to manufacturers and other downstream buyers.
- New duties start June 18, 2026
- Covered imports include chassis and related subassemblies
- Mexico, Thailand and Vietnam each have their own order
- Importers and downstream buyers may absorb the added cost
- At the federal Commerce Department, importers bringing chassis and related subassemblies from Mexico, Thailand and Vietnam into the United States now have a new cost to build into their math
At the federal Commerce Department, importers bringing chassis and related subassemblies from Mexico, Thailand and Vietnam into the United States now have a new cost to build into their math. The antidumping duty orders took effect June 18, 2026, so the extra border charge starts immediately for covered entries.
Commerce said it was acting on affirmative final determinations from both Commerce and the U.S. International Trade Commission, or ITC. The ITC found that a U.S. industry was materially injured by less-than-fair-value imports from the three countries, and Commerce issued one order each for Mexico, Thailand and the Socialist Republic of Vietnam.
The cost shows up at customs
The practical effect is simple: U.S. Customs and Border Protection will collect cash deposits on covered imports, turning the trade ruling into a real line item at the border. For importers, customs brokers and manufacturers that rely on these parts, that can raise landed costs before the chassis ever reaches a warehouse or assembly line.
Those costs do not stop with the importer of record. Once duties are built into pricing, downstream buyers can feel them in the equipment or products built around the covered parts, even if they never handle the chassis themselves.
How broad the net runs
The scope is not limited to one finished product. Commerce says the orders cover chassis and subassemblies, whether finished or unfinished, assembled or unassembled, and include parts such as frames, running gear and assemblies that connect to the chassis frame.
The notice also says some processing in a third country does not take a product out of scope, while individual components entered and sold by themselves are not covered. For importers of the covered chassis and subassemblies, that means added border costs that can follow the part far down the supply chain.
