President Trump issued Proclamation 11002 imposing a 25% tariff on certain advanced computing chips critical to artificial intelligence, effective January 15, 2026, pursuant to Section 232 of the Trade Expansion Act of 1962 based on claims of national security threats. The tariff targets logic integrated circuits meeting specific technical parameters including defined ranges for Tera Tensor Performance (TTP) and total DRAM bandwidth, such as the NVIDIA H200 and AMD MI325X chips, while exempting imports that support U.S. data centers, research and development, startups, and other domestic technology needs.
The proclamation represents the seventh active Section 232 tariff order, joining existing tariffs on steel, aluminum, passenger vehicles, copper, timber, and truck parts, demonstrating the administration's aggressive expansion of national security trade authority beyond traditional defense applications. The Commerce Department concluded that semiconductors are "essential to the United States' economic, industrial, and military strength" and that insufficient domestic production capacity leaves the country dependent on foreign sources. The proclamation indicates broader tariffs on semiconductors and derivative products may be imposed within 90 days, with an accompanying "tariff offset program" to incentivize domestic manufacturing.
Given the breadth of exemptions for nearly all domestic uses, the 25% tariff appears primarily designed to restrict imports of AI commodities ultimately intended for export to China rather than to address legitimate supply chain vulnerabilities. The action demonstrates the administration's willingness to invoke elastic "national security" justifications to implement industrial policy and trade restrictions through unilateral executive authority, bypassing congressional trade powers and international trade obligations.
