U.S. push to harden chip export controls

Micron is pushing Congress to turn U.S. chip-tool curbs on China into law, a move that would make them harder for any administration to loosen. (reuters.com) Reuters reported on April 22 that Micron, the largest U.S. memory chipmaker, has been lobbying for tighter limits on equipment Chinese memory rivals use to make chips. A House Foreign Affairs Committee panel advanced the MATCH Act the same day. (reuters.com) (foreignaffairs.house.gov) The bill was introduced in the House on April 2 by Rep. Michael Baumgartner, a Washington Republican, with bipartisan cosponsors, and companion legislation was introduced in the Senate by Sens. Pete Ricketts and Andy Kim. The House bill is H.R. 8170, the Multilateral Alignment of Technology Controls on Hardware Act, or MATCH Act. (baumgartner.house.gov) (govtrack.us) (foreign.senate.gov) At issue are deep ultraviolet lithography tools, the machines that project circuit patterns onto silicon wafers like a stencil for chips. The current U.S. system relies heavily on export-control rules written by the Commerce Department, while the proposed legislation would write more of those restrictions into statute. (reuters.com) (govtrack.us) That matters because Commerce rules can be revised by regulators, but a statute takes Congress to change. Reuters reported that one Micron-backed proposal would convert some discretionary controls into mandatory ones, affecting which companies can add manufacturing capacity in China and which firms can join standards-setting work. (reuters.com) Washington has been tightening these controls for years. On December 2, 2024, the Commerce Department said it was adding controls on 24 types of semiconductor manufacturing equipment, 3 software tools, high-bandwidth memory, and 140 Entity List additions tied to China’s semiconductor and military ecosystem. (bis.gov) The MATCH Act is aimed at what lawmakers call gaps between U.S. rules and allied-country rules. Baumgartner’s office said the bill is meant to align U.S. controls with partners, while the House Foreign Affairs Committee said it would require Commerce and State to review which chokepoint tools and Chinese fabs should face tighter restrictions. (baumgartner.house.gov) (foreignaffairs.house.gov) The bill text names Chinese companies including ChangXin Memory Technologies, Semiconductor Manufacturing International Corp., Yangtze Memory Technologies, Huawei, Naura, and Shanghai Micro Electronics Equipment. It says those firms warrant comprehensive controls because of their role in advanced-node chipmaking and China’s military-civil fusion strategy. (govtrack.us) The foreign company most exposed is ASML, the Dutch maker of the world’s most advanced lithography systems. ASML said in its 2025 annual report that total net sales were €32.7 billion, and outside reporting on its 2025 results said China accounted for about a third of sales last year before the company guided lower for 2026. (asml.com) (cnbc.com) (scmp.com) Supporters say the bill closes loopholes and keeps U.S. and allied tools out of Chinese advanced fabs. Critics and affected companies have warned in earlier debates that broader controls can hit sales for American and European equipment makers and complicate coordination with allies whose companies still serve China’s chip market. (foreignaffairs.house.gov) (csis.org) (reuters.com) The immediate question is no longer whether Washington wants tighter chip controls on China; it is whether Congress will lock them in. After the April 22 committee vote, that fight has moved from agency rulemaking into the legislative process. (foreignaffairs.house.gov) (reuters.com)
