Commerce Sets Duties on Chinese, Mexican Van Trailers Up to 128.7%
Preliminary findings impose countervailing duties ranging from 1.9% to 128.7% on van-type trailers assembled in China and Mexico, offsetting subsidies the Department of Commerce says undercut U.S. manufacturers.

How much more will Chinese and Mexican trailers cost after the new duties?
The U.S. Department of Commerce published preliminary findings from its investigation into van-type trailers assembled outside the U.S., calculating new countervailing duties to offset subsidies in China and Mexico. Chinese trailers face duties ranging from 82.3% to 128.7%. Trailers imported from Mexico face duties between 1.9% and 1.95%.
The duties apply to van-type trailers, the dry and refrigerated boxes that make up the majority of over-the-road trailer purchases. The Department of Commerce found that both countries were unfairly subsidizing their van trailer industries, giving manufacturers an advantage over U.S.-based builders.
What the duty range means for trailer orders
The 82.3% to 128.7% range on Chinese trailers reflects different subsidy levels across manufacturers investigated by Commerce. A $50,000 Chinese dry van facing the low end of the duty range would carry an additional $41,150 in duties. The same trailer at the high end would add $64,350. Mexican trailers see a narrower band, adding roughly $950 to $975 on a $50,000 unit at the 1.9% to 1.95% range.
These are preliminary rates. Final duties will be set after Commerce completes its investigation and the International Trade Commission rules on whether the subsidized imports caused material injury to the U.S. industry. The timeline mirrors the antidumping case on chassis from Mexico, Thailand, and Vietnam that the ITC finalized earlier this month.
How this stacks with existing tariffs
The countervailing duties land on top of any existing tariffs. Chinese trailers already face Section 301 tariffs that have ranged from 25% to higher levels depending on the product classification and trade negotiations in effect. Mexican trailers entered duty-free under USMCA rules, though the U.S. announced it will skip the July 1 USMCA renewal, triggering rolling reviews of the trade pact.
Fleets that locked in trailer orders from Chinese or Mexican builders before the preliminary duties took effect will see those orders grandfathered at the old rate if they clear customs before Commerce publishes final findings. Orders placed after the preliminary determination will be subject to the new duties at the port of entry.
What this means for U.S. trailer supply
U.S. trailer manufacturers petitioned Commerce to investigate Chinese and Mexican subsidies, arguing that below-market pricing from subsidized imports was undercutting domestic production. The preliminary duties give U.S. builders pricing room, but they do not immediately add trailer capacity to the market. Lead times for new trailers from U.S. plants remain in the 12- to 16-week range for dry vans and longer for refrigerated units, depending on the builder and spec.
Small fleets that relied on lower-cost Chinese or Mexican trailers to stretch capital budgets now face a choice: pay the duty premium, wait for U.S. production slots, or buy used. The used trailer market has tightened as import volume jumped 9.7% in June, pulling more containers and chassis into service earlier than the usual peak season timing.
When the final duties take effect
Commerce will publish final countervailing duty rates after completing its investigation, typically within six months of the preliminary determination. The ITC must then rule on whether the subsidized imports caused material injury to the U.S. trailer industry. If the ITC rules affirmatively, the final duties become permanent. If the ITC rules negatively, the duties are lifted and any collected duties are refunded.
Fleets with trailer orders in process should confirm with their dealers whether the preliminary or final duty rate applies to their specific order based on the customs entry date. The distinction can swing the landed cost by tens of thousands of dollars per unit on Chinese trailers.
