Trump Signs Proclamation on Tariffs
President Donald Trump has enacted a new proclamation that modifies Section 232 of national security tariffs concerning imported steel, aluminum, and copper. This amendment is part of the ongoing adjustments to the “America First” trade policy.
Starting June 8th at 12:01 AM ET, these changes will introduce temporary reductions for specific industrial and agricultural machinery, while also expanding the range of certain heavy metal imports.
The goal of these modifications is to alleviate financial pressures on crucial domestic sectors like agriculture and construction, all while maintaining the protective trade policies currently in place. These adjustments are intended to last until December 31, 2027.
“These tariff changes are temporary and will last until December 31, 2027. This is a long-term investment that will rebuild our nation’s industrial base,” said a White House spokesperson.
Under the new rules, import duties on important agricultural machinery, especially high-capacity equipment like combines and harvesters, will be reduced from 25% to 15%. Additionally, tariffs on HVAC systems and their components will also decrease to 15%.
The Republican administration broadened the definition of industrial equipment eligible for this reduced rate to include large mobile machinery such as bulldozers and forklifts but only for imports from countries with active trade agreements with the U.S.
Meanwhile, raw commodity-grade metals and products primarily made of steel, aluminum, or copper, such as steel coils and aluminum sheets, will continue to face a significant basic customs duty of 50%. For downstream products containing these metals, the general tariff will remain at 25%.
To address what seems to be a trade loophole, the order includes two new metal-derived products—steel racks and aluminum slate—under this 25% tariff category. However, products with 15% or less of steel, aluminum, or copper by weight will still be completely exempt from Section 232 duties.
To promote the use of U.S.-sourced raw materials within global supply chains, the White House has introduced a new 10% preferential tariff rate for foreign manufacturers. This lower rate applies if the imported finished product consists of at least 85% U.S.-sourced metals, specifically steel melted and cast in the U.S., or aluminum and copper processed domestically.
This change marks a shift from the stricter previous standard, which required 95% U.S. metals for full exemption. The Trump administration emphasized that this adjustment is meant to channel private and foreign investments back into the U.S. domestic manufacturing and smelting sectors.
By selectively reducing tariffs on heavy equipment, President Trump seems to be trying to strike a balance between long-term protectionist policies and the pressing economic needs of domestic industries, particularly in the agricultural sector and industrial supply chains.
