President Donald Trump announced a new 100% tariff on imported semiconductors, but with a major exception: it will not apply to companies that manufacture in the U.S. or have committed to do so. This policy is part of his broader effort to boost domestic manufacturing. He made the announcement as Apple pledged an additional $100 billion investment in the U.S. to avoid the new fees. Trump warned that companies must follow through on their commitments to build factories to maintain the exemption.
