Trump said the tariffs on heavy trucks were to protect US manufacturers from “unfair outside competition” and that the duties would help lift American companies such as Peterbilt and Mack Trucks.
These firms “will be protected from the onslaught of outside interruptions”, he wrote.
The new levies on kitchen and bathroom cabinets, as well as some other furniture, were in response to high levels of imports, which hurt local manufacturers, the president said.
He added that the US would start charging a 30% tariff on upholstered furniture from next week.
The new duties come as part of an expansion of Trump’s tariff policies, which have targeted both global trading partners and specific industries.
Trump’s sweeping new tariffs on more than 90 countries came into effect in early August, as part of his policies aimed at boosting jobs and manufacturing in the US, among other political goals.
Earlier this year, the US Chamber of Commerce, external urged the White House against introducing new tariffs, arguing that many parts used in truck production are sourced “overwhelmingly” from countries like Mexico, Canada, Germany, Finland and Japan.
The organisation added that these countries are “allies or close partners of the United States posing no threat to US national security.”
Mexico and Canada are among the biggest suppliers of parts for medium and heavy-duty trucks, accounting for more than half of total US imports in the sector last year, said the chamber.
It warned that it is “impractical” to expect many of these parts to be sourced domestically, resulting in higher costs for the industry.
