President Donald Trump said that all medium and heavy-duty trucks will face a new 25% tariff starting Nov. 1.

Trump made the announcement in a post on Monday on his Truth Social platform writing, "Beginning November 1st, 2025, all Medium and Heavy Duty Trucks coming into the United States from other Countries will be Tariffed at the Rate of 25%. Thank you for your attention to this matter!"

In September, Trump said pharmaceuticals, furniture, and heavy truck  would face new duties on Oct. 1. He has argued that foreign-made heavy trucks and parts are hurting domestic producers that need to be defended.

What does the new tariff mean for the auto industry?

Big picture view:

Mexico is the largest exporter of medium- and heavy-duty trucks to the U.S. Citing government statistics, Reuters noted that imports of larger vehicles from Mexico have tripled since 2019 to around 340,000 now. 

Based on the United States-Mexico Canada agreement (USMCA), medium and heavy-duty trucks move tariff free if roughly 64% of a heavy truck's value originates in the U.S., with parts like engines and axles, raw materials such as steel, or assembly labor.

Reuters reported that tariffs could also affect Chrysler parent company Stellantis, which manufactures heavy-duty Ram trucks and commercial vans in Mexico. Stellantis has requested that the White House not enforce steep tariffs on its Mexican-made trucks. And Volvo is constructing a $700 million heavy-truck factory in Monterrey, Mexico, set to begin operations in 2026.

Citing Treasury Department data released 29, FOX Business noted that the federal government collected $31.3 billion in tariff revenue in September,

Meanwhile, tariff revenues soared from $17.4 billion in April to $23.9 billion in May, before ascending to $28 billion in June and reaching $29 billion in July.
