On October 28, 2026, the US Department of Commerce issued antidumping and countervailing duty orders covering box semitrailers and their components from China. The orders set an antidumping cash deposit rate of 129.73% and a countervailing duty rate of 134.75%, for a combined rate of 264.48%.

The combined rates represent a substantial additional cost for affected imports. For buyers and suppliers, the immediate question is how that cost will be reflected in transactions and whether purchases remain commercially viable at the resulting price.

Potential effects on sourcing and supply

The orders could influence purchasing decisions for both complete semitrailers and covered components. Higher import costs may lead buyers to reconsider sourcing arrangements, while exporters may face pressure on pricing and demand.

Any broader changes to supply chains will depend on how buyers and suppliers respond. The combined rate indicates the scale of the immediate cost pressure, but it does not by itself establish how trade flows or sourcing patterns will change.
