Overview
- U.S. Commerce Secretary Howard Lutnick privately pressed ASML executives in meetings in April that he was concerned one of ASML’s extreme ultraviolet (EUV) systems or related transport gear may have reached China.
- ASML has publicly and repeatedly denied any EUV shipments to China and circulated an internal presentation stating there is "no indication of any ASML EUV system in China."
- Senior U.S. officials told reporters they hold evidence pointing to exports of EUV-specific components or specialized transport equipment to China but they have declined to share that evidence with ASML or make it public.
- There is no independent, public confirmation that a complete ASML EUV machine is operating in China, and the dispute currently rests on classified or undisclosed information rather than a public finding.
- The case matters because ASML is the sole maker of EUV systems, which are essential to making the most advanced chips, and a verified breach could tighten export rules, deepen U.S.-EU diplomatic strains, and threaten ASML’s China revenue and compliance standing.
