Federal Appeals Court Upholds Trump 10% Tariffs During Legal Fight

A federal appeals court ruled the Trump administration can continue enforcing 10% global tariffs while a legal challenge proceeds. The decision keeps the levies in place for importers of truck parts, chassis, axles, and other equipment sourced from countries subject to the tariff.

Will the 10% tariffs stay in place through the legal fight?

Yes. The appeals court denied a request to block enforcement while the case moves forward. Importers challenging the tariffs must continue paying the 10% levy on covered goods until the court issues a final ruling. No timeline was provided for when the case will conclude.

The ruling affects equipment buyers who import components from any of the countries covered by the global tariff. That includes chassis from Mexico, Thailand, and Vietnam already subject to separate antidumping duties, axles and suspension parts from China, and telematics hardware from Taiwan. Fleets and shops that source aftermarket parts internationally now face the combined cost of existing duties plus the 10% global tariff with no near-term relief.

What this means for cross-border equipment costs

The court decision removes uncertainty about whether the tariffs would be suspended during litigation. Importers who had delayed orders hoping for a stay now know the 10% levy will remain through the appeals process. For fleets that spec Canadian-built tractors or Mexican-assembled trailers, the tariff adds to the cost pressure already created by antidumping duties on chassis from Mexico, Thailand, and Vietnam finalized earlier this month.

Small fleets and owner-operators who buy used equipment are not directly hit by the tariff at purchase, but the levy flows through to parts pricing. Aftermarket suppliers that import brake drums, wheel-end components, or electrical parts from tariff-covered countries typically pass the cost to distributors, who pass it to shops, who pass it to the truck owner at the counter. The appeals court ruling means that passthrough continues with no interruption.

The 10% global tariff sits on top of other trade actions already in force. The Commerce Department recommended duties on Chinese and Mexican van trailers in early June. USTR imposed separate 10% to 12.5% tariffs on 60 countries over forced labor imports. The appeals court decision does not affect those other levies, only the 10% global tariff now confirmed to stay in place during litigation.

What fleets should do now

Fleets that had delayed equipment orders or parts purchases waiting for the court to block the tariff should treat the 10% levy as permanent for planning purposes. The appeals process can take months or longer, and even if the challengers ultimately win, there is no guarantee of retroactive refunds. Importers seeking tariff refunds face a separate legal process at Customs and Border Protection that remains unresolved.

For shops that stock imported parts, the ruling means supplier pricing will not drop in the near term. Distributors who raised prices when the tariff took effect are unlikely to reverse those increases while the levy remains enforceable. Fleets that maintain their own parts inventory should budget for the higher cost on any components sourced from tariff-covered countries.

Cross-border carriers face no direct FMCSA compliance consequence from the tariff itself, but the cost of replacement parts for tractors and trailers that cross into Canada or Mexico will remain elevated. The uncertainty around USMCA renewal adds a separate layer of risk for fleets that depend on cross-border equipment supply chains, but the appeals court ruling addresses only the 10% global tariff, not the trade agreement.

The court provided no written opinion with the ruling, only an order allowing enforcement to continue. The legal challenge will proceed on the merits, but the tariff stays in place until the case concludes.
