The Trump administration recently announced its intention to impose a 25% tariff on heavy trucks manufactured outside the United States, a measure set to take effect on October 1, 2025. As explained in a post on his Truth Social platform on September 25, the goal is to protect American manufacturers from what he described as unfair foreign competition, thereby strengthening the national industry not only economically but also in terms of security.
In April, the Department of Commerce launched an investigation to assess the potential national security impacts of truck imports. Although Trump’s announcement did not specify which classes of trucks would be affected, this earlier investigation provides some context, suggesting that the tariffs could cover a wide range of vehicles and components within the sector.
A contradiction arises when considering that manufacturers like Peterbilt, Mack Trucks, Freightliner, and Kenworth manufacture both inside and outside the United States, which could result in mixed consequences for the very companies the measure aims to protect. While the intention is to limit the entry of foreign-manufactured trucks, these companies could face complications in their international operations or in sourcing parts produced abroad.

ATA opposes tariff increase on heavy trucks
The legal basis for this measure lies in Section 232 of the Trade Expansion Act of 1962, which grants the government authority to impose tariffs if certain imports are found to pose a threat to national security. However, the trucking industry has openly voiced its opposition.
The American Trucking Associations (ATA) has expressed its rejection of the tariffs since the possibility was first raised. In May, the organization shared concerns over the potential economic repercussions, warning that the measure could further weaken a sector already facing a complex operating environment. According to statements reported by Transport Topics, the ATA stated that there is no evidence that heavy truck imports pose a real threat to national security.
From the ATA’s perspective, imposing tariffs on trucks manufactured in Mexico would be particularly problematic. The association emphasized that truck production in North America is highly integrated, and that restricting imports from a neighboring and trade-partner country like Mexico could be counterproductive. They also highlighted that the trucking industry is extremely competitive and operates on very narrow profit margins, limiting its ability to absorb additional costs.
Finally, the ATA warned that a 25% tariff would significantly increase the price of a new truck. A Class 8 vehicle, which currently costs an average of $170,000, could rise to $224,000 due to the combined impact of the tariff and federal tax. According to the association, this price hike would be unaffordable for most fleets, forcing them to extend the usage cycles of their current trucks. This would, in turn, affect both new vehicle production and parts manufacturing, negatively impacting the broader North American economy.
