ASML Holding NV said on June 18, 2026, that it has never shipped an extreme-ultraviolet (EUV) lithography machine or EUV-specific components to China, denying U.S. Commerce Secretary Howard Lutnick’s reported concern that an EUV system may have reached the country.
U.S. Allegation and ASML Response
In April 2026, U.S. Commerce Secretary Howard Lutnick raised concerns in meetings with ASML executives that one of the company’s top-tier EUV systems might be in China, potentially violating export restrictions. ASML issued a categorical denial, stating it has never shipped an EUV machine or any component designed for EUV systems to China.
Following those meetings, ASML circulated a document titled “No indication of any ASML EUV System in China,” which detailed its internal inventory: 314 EUV systems currently operating worldwide, 26 decommissioned, and none located in China.
Some senior U.S. officials believe there is evidence that EUV-related components or transport equipment may have reached China, but no such evidence has been made public. The U.S. Commerce Department and the White House declined to comment, and no formal enforcement action related to an alleged EUV transfer has been reported.
Export Controls and Operational Risks
ASML, the Dutch manufacturer holding a near-monopoly on EUV lithography equipment used for advanced chip production, emphasized technical factors that make an unrecorded transfer unlikely. EUV systems are produced in small quantities, roughly the size of a school bus, weigh about 180 metric tons, and require ongoing maintenance by ASML personnel, which the company says ensures they remain trackable throughout their operational life.
The Netherlands, under sustained U.S. pressure, has refused to license EUV exports to China. U.S.-led export controls have long barred shipment of such systems, forming part of a broader effort to limit China’s access to cutting-edge chipmaking tools. Separately, U.S. lawmakers have proposed the MATCH Act, which would further restrict exports and servicing of certain ASML deep-ultraviolet (DUV) immersion tools to China.
Following initial reports, ASML’s shares declined modestly, reflecting increased geopolitical scrutiny. The company said it regularly engages with governments worldwide, recognizes the national-security rationale behind export controls, and is fully committed to compliance. ASML has previously rejected what it called unfounded rumors of non-compliance, describing them as inaccurate and damaging to its reputation.
This public dispute places ASML at the center of potential enforcement actions and tighter export curbs, increasing near-term policy risks for the chip-equipment maker.
