LOS ANGELES, June 1 (Reuters) – U.S. President Donald Trump on Monday signed a proclamation amending his Section 232 national security tariffs ​on some aluminum, steel and copper ‌imports, the White House said.

• The proclamation lowers tariffs on some steel and aluminum derivative products, including certain types of agricultural machinery and residential heating, ‌air ​conditioning and ventilation equipment to ⁠15% from 25% ⁠previously.

• It makes mobile industrial equipment, such as bulldozers and forklifts, subject to a 15% tariff “when imported from trade deal countries ​that are entitled to such treatment,” the White House said in a statement.

• The ⁠order also allows foreign ⁠companies to qualify for a 10% ​tariff if “their capital equipment includes at least 85% ​U.S. melted and poured or smelted and ‌cast steel or aluminum by weight.”

• The order adds two new categories of steel and aluminum derivative import products that will ⁠be subject to 25% duties: steel racks and aluminum lithographic plates.

• The adjustments will become effective for ⁠goods imported ‌or withdrawn from bonded warehouses ⁠after 12:01 a.m. EST (0401 GMT) on ​June ‌8.

• The changes will remain in ​place until ⁠December 31, 2027 “to spur near–term investments that will rebuild the Nation’s industrial base,” the White House said.
