U.S. President Donald Trump signed a proclamation amending his Section 232 national security tariffs on some aluminum, steel, and copper imports, according to the White House. The changes are designed to remain in place until December 31, 2027, to spur near-term investments that will rebuild the industrial base of the nation.
Tariff reductions and country exemptions
The newly issued proclamation lowers tariffs on several steel and aluminum derivative products, reducing the rate to 15 percent from 25 percent previously. This reduction applies directly to certain types of agricultural machinery and residential heating, air conditioning, and ventilation equipment.
Additionally, the order makes mobile industrial equipment, such as bulldozers and forklifts, subject to a 15 percent tariff. However, the White House statement noted that this specific rate applies when these goods are imported from trade deal countries that are entitled to such treatment.

Local sourcing incentives and new duties
To incentivize domestic production, the executive order allows foreign companies to qualify for a lower 10 percent tariff. To meet this threshold, the capital equipment of these firms must include at least 85 percent U.S. melted and poured or smelted and cast steel or aluminum by weight.
Conversely, the order expands the tariff scope by adding two new categories of steel and aluminum derivative import products that will now be subject to higher 25 percent duties. These newly restricted categories are steel racks and aluminum lithographic plates.
Implementation timeline
The tariff adjustments are scheduled to take effect for goods imported or withdrawn from bonded warehouses after 12:01 a.m. EST (04:01 GMT) on June 8.
