A 25% truck tariff is slated for Oct. 1, although official documentation has yet to be published. “We are closely monitoring the situation, but it’s too early to provide a detailed comment,” a Daimler Truck North America spokesperson said Monday by email. Truck manufacturers pointed out that 99% of Class 8 trucks from four OEMs, Daimler Truck North America, International, Paccar and Volvo Trucks North America, are manufactured domestically. When adding in medium-duty manufacturers, including just a handful of other players, the industry assembled 88% of medium-duty and heavy-duty trucks in 2024, Stellantis noted. Truck manufacturers called for new tariffs not to stack on top of existing ones.
