President Donald Trump said the United States will impose a 100% tariff on all imported semiconductors and computer chips, escalating his administration’s effort to shift high-tech manufacturing back to domestic soil. Speaking in the Oval Office alongside Apple Chief Executive Officer Tim Cook, Trump stressed that companies that already build— or have unequivocally committed to build— chip facilities in the United States will not face the duty. He singled out Apple and Nvidia as examples of firms that would be spared under the planned regime. During the event Cook announced Apple will invest an additional $100 billion in U.S. operations over the next four years, lifting the iPhone maker’s cumulative pledge to about $600 billion. Apple said the outlay will expand its supplier network and add manufacturing capacity, including a new glass plant in Kentucky. Details on the timing and legal framework of the tariff were not released. The measure would affect a market that imported an estimated $63.7 billion of semiconductors in 2024, with major suppliers including Malaysia, Taiwan and Vietnam.
