U.S. Puts Antidumping Duties on Chassis from Mexico, Thailand, and Vietnam
Estimated reading time: 4–6 minutes
On June 18, 2026, the U.S. Department of Commerce put antidumping duties on chassis from Mexico, Thailand, and Vietnam. This decision comes after finding that these countries sold chassis in the United States at less-than-fair-value prices. This means they were sold for less than it costs to make them.
Commerce’s Determinations
The Department of Commerce found that many companies were selling chassis for prices that hurt U.S. businesses. They published these findings on April 23, 2026. This was a part of a bigger investigation on whether trading practices were fair.
International Trade Commission Involvement
On June 8, 2026, the U.S. International Trade Commission (ITC) agreed with the Commerce Department. They said the U.S. industry was being hurt by cheap chassis coming from these countries. This allowed the Commerce Department to set up duties or extra taxes on these products.
Details of the Chassis Orders
Chassis are frames or trailers used to carry containers. They can be used on roads, ships, or trains. This decision covers all chassis coming from Mexico, Thailand, and Vietnam, whether finished or not.
Implementation Dates
Antidumping duties affect chassis entries that were brought into the U.S. after September 29, 2025. The duties can now be assessed on any chassis that is still in customs or has not been settled yet.
Rates of Duties
Different companies in Mexico, Thailand, and Vietnam will have different duty rates. For example, in Thailand, Dee Siam Manufacturing Co., Ltd. will face duties of 72.85%. Companies from Mexico have a general rate of 32.37%. For Vietnam, all concerned exporters must pay a 186.84% duty.
Custom Procedures
The Department of Commerce will direct the U.S. Customs and Border Protection (CBP) to collect these extra taxes. They need to keep a watch on the entries until further notice. For some time, starting from March 28, 2026, some imports were not charged duties, but that has now changed after this release.
Annual Inquiry Service Lists
The Department of Commerce will maintain a list each year of all parties interested in these orders. People who want to be on this list must sign up within 30 days of the order being published. This helps ensure everyone follows the new rules effectively.
Final Details
This step is a significant move to protect U.S. businesses from unfair competition. By applying these duties, the U.S. aims to ensure fair trading and to support its industries. The rules will affect how companies bring chassis into the country from Mexico, Thailand, and Vietnam.
The order and all its details can be found published in the Federal Register under Volume 91, Number 117. This measure shows a strong commitment to maintaining a level playing field for U.S. companies and ensuring fair prices in the market.
