President Donald Trump said Friday he will unveil new tariffs on imported steel next week and on semiconductor chips the week after, broadening his protectionist trade agenda. Speaking with reporters aboard Air Force One, Trump stated that the duties will start at “a lower rate” to give manufacturers time to shift production to the United States, then climb sharply. He indicated chip tariffs could rise from around 100% to as much as 200% or 300% if companies continue making the components overseas. The administration plans to rely on Section 232 of the Trade Expansion Act of 1962, which allows tariffs on national-security grounds. Trump suggested firms investing in U.S. fabrication plants, including Taiwan Semiconductor Manufacturing Co. and Samsung Electronics Co., might receive exemptions from the highest rates. The announcement comes two months after Washington doubled existing steel and aluminum levies to 50% and as the White House weighs additional sanctions on Russian energy and further duties on Chinese goods. Industry groups warn steep chip tariffs could ripple through electronics, auto and AI supply chains, but Trump argued the phased approach will spur companies to “come in and build” domestically.
