Temporary tariff changes aim to boost investment, manufacturing growth, and domestic metal use
The Trump administration has revised tariffs on a range of agricultural and industrial equipment imports, lowering duties on certain products while creating new incentives for manufacturers that incorporate US-produced steel and aluminum into their operations.
The changes were announced Monday through a presidential proclamation that adjusts existing tariffs on steel, aluminum and copper-related imports. The White House said the measures are intended to support domestic manufacturing, encourage investment and address national security concerns tied to strategic metals.
Under the updated framework, tariffs on agricultural machinery such as combines and harvesters will be reduced to 15% from 25%. The administration is also extending the 15% tariff treatment already available to some industrial equipment to include mobile industrial machinery, including bulldozers and forklifts, when imported from countries covered by qualifying trade agreements.
The proclamation also introduces a preferential 10% duty rate for foreign manufacturers whose capital equipment contains at least 85% US-produced steel or aluminum by weight. To qualify, the metals must be either melted and poured or smelted and cast in the United States.
Impact for Canada?
While Canada was not directly targeted by the measures, the policy could create headwinds for some Canadian exporters. By offering lower tariff rates for equipment made largely with US-produced steel and aluminum, the administration is creating an incentive for manufacturers to source more materials domestically, potentially reducing demand for imported metals and industrial inputs from Canada.
According to the White House, the revised tariff structure will remain in effect through Dec. 31, 2027, as part of a broader effort to stimulate near-term industrial investment.
The administration framed the changes as part of its ongoing Section 232 trade strategy, arguing that tariffs have helped strengthen domestic production of steel, aluminum and copper while protecting industries viewed as vital to national security.
The White House said the United States rose to become the world's third-largest steel producer in 2025, attributing the gain to the administration's tariff policies. It also highlighted planned additions of more than four million tons of crude steelmaking capacity over the next two years, with projects slated for states including West Virginia, Arkansas and South Carolina.
Investment activity has also expanded across the aluminum and copper sectors, according to the administration. The White House pointed to a joint venture between Century Aluminum and Emirates Global Aluminum to construct what it described as the first new aluminum smelter built in the United States in decades. It also cited ongoing expansion efforts by copper producers and processors including Highland Copper, Ivanhoe Electric, Rio Tinto and Wieland.
The administration said maintaining and strengthening the tariff program remains essential to preserving momentum in domestic metals production and ensuring U.S. manufacturers can compete against lower-priced foreign imports.
Brazil targeted
The tariff revisions come as the administration pursues a broader trade agenda across multiple sectors and trading partners. Separately, US trade officials have proposed new duties on a range of Brazilian imports under a separate trade enforcement process. Products already subject to Section 232 national security tariffs, including steel, aluminum and copper, would continue to be covered by those existing measures.
The latest action builds on a series of Section 232 measures implemented during both Trump administrations. The White House said the broader strategy has been used to support domestic manufacturing in industries ranging from metals and automobiles to semiconductors, critical minerals and pharmaceuticals.
The administration also pointed to recent manufacturing data, stating that U.S. manufacturing activity in May expanded at its fastest pace in four years and marked a fifth consecutive month of growth.
