President Donald Trump has announced adjustments to tariffs on steel, aluminum, and copper imports, a move aimed at bolstering U.S. economic activity. In a recent executive order, Trump lowered tariffs on agricultural equipment such as combines and harvesters, as well as heating, ventilation, and air conditioning (HVAC) systems, from 25% to 15%.
Encouraging Use of U.S. Metals
The order also expands the category of industrial equipment subject to a 15% tariff to include mobile industrial equipment like bulldozers and forklifts, provided they are imported from countries with a trade agreement with the United States. Additionally, countries using at least 85% U.S. melted and poured or smelted and cast steel or aluminum by weight may qualify for a reduced 10% duty rate. This initiative is designed to incentivize foreign companies to utilize U.S. metals.
The changes are set to take effect immediately and will remain in place until the end of 2027. Trump stated in his order that these temporary modifications account for the significant role these products play in productive economic activity within the United States.
Background on Tariff Adjustments
Tariffs on copper, steel, and aluminum were initially imposed during Trump’s first term in 2018 under Section 232 of the Trade Expansion Act of 1962, which permits tariffs on imports deemed a threat to national security. These tariffs were renewed in April 2025, with further adjustments made in June 2025, when tariffs on steel and aluminum imports were increased to 50% from 25%.
In April 2026, Trump set a flat 50% rate for goods composed entirely or almost entirely of aluminum, steel, or copper, such as steel coils or aluminum sheets, while derivative products made substantially of these metals were subjected to a 25% tariff rate.
Political Implications
Barry Appleton, a law professor and co-director of New York Law School’s Center for International Law, suggests that the recent tariff adjustments may be politically motivated, particularly in light of the upcoming midterm elections. With farm bankruptcies on the rise and declining farm sentiment, Republican senators have expressed concerns about potential midterm losses in key agricultural states. Appleton believes that the tariff modifications are an attempt by the White House to address these concerns and appeal to the farm belt before voters head to the polls.
