On October 17, 2025, President Donald J. Trump signed a proclamation invoking Section 232 of the Trade Expansion Act of 1962 to impose tariffs on imports of medium- and heavy-duty vehicles, parts, and buses. The proclamation includes a 25% tariff on medium- and heavy-duty trucks and parts, along with a 10% tariff on buses. This initiative aims to enhance American manufacturing capabilities and address national security concerns linked to reliance on foreign suppliers for essential components of the trucking industry.

The investigation conducted by the Secretary of Commerce under Section 232 indicated that imports of these vehicles and parts pose a threat to national security, as domestic production is vital for military readiness and emergency response. The tariffs are intended to strengthen the U.S. trucking industry’s ability to meet national needs, recognizing that trucks and buses are crucial for transporting goods across the country. Additionally, the proclamation aligns the tariff programs for medium- and heavy-duty trucks and automobiles to streamline the import adjustment process for manufacturers.

President Trump’s administration has previously implemented tariffs and policies aimed at securing critical industries and enhancing domestic manufacturing. The current tariffs are part of a broader effort to ensure that U.S. trade policies align with national interests and mitigate risks associated with offshoring. The Department of Commerce continues to investigate other sectors, highlighting the administration’s ongoing commitment to protecting American manufacturing and economic sovereignty.
