Commerce secretary ordered to report on data‑center chip market by July 1, 2026

President Donald J. Trump issued a proclamation finding that imports of semiconductors, semiconductor manufacturing equipment, and derivative products threaten U.S. national security and directing a two-phase response. Effective January 15, 2026, a 25 percent ad valorem tariff will apply to certain advanced computing chips and derivative products ("Covered Products"), with exemptions for uses that support the U.S. technology supply chain (for example, data centers, R&D, repairs, startups, certain consumer and public-sector uses). The proclamation directs the Secretary of Commerce and the U.S. Trade Representative to negotiate agreements and report back within 90 days, and requires Commerce to monitor imports and provide a data-center market update by July 1, 2026. The administration also left open the possibility of broader tariffs and a tariff-offset program after negotiations conclude.
