U.S. Raises Alarm Over Possible ASML EUV Machine in China – Company Denies Any Breach

US Concerns Over Potential EUV Leak to China
Commerce Secretary Howard Lutnick told senior ASML executives in a series of meetings that Washington suspects one of the Dutch firm’s extreme-ultraviolet (EUV) lithography systems may have entered China in violation of U.S.–led export restrictions. EUV tools are the only equipment capable of printing the most advanced semiconductor patterns and have been barred from export to China since the first Trump administration.
Export-Control Background and ASML’s Role
EUV machines, roughly the size of a school bus and weighing about 180 tonnes, are produced in limited numbers and require continuous on-site servicing by ASML staff. The United States has used the Wassenaar Arrangement and subsequent national rules to prohibit their sale to Chinese chipmakers such as Huawei Technologies and SMIC. The Netherlands, where ASML is headquartered, enforces “the strictest” export rules for these tools and has also restricted certain deep-ultraviolet (DUV) lithography equipment.
Key Actors in the Dispute
- Howard Lutnick – U.S. Secretary of Commerce.
- Christophe Fouquet – CEO of ASML Holding NV.
- Sjoerd Sjoerdsma – Dutch Minister for Foreign Trade.
- Senior Trump-administration officials – unnamed senior officials who claim evidence of EUV-related exports.
- U.S. Congress – sponsors a bipartisan bill (the MATCH Act) to align foreign export controls with U.S. standards.
Timeline of Recent Developments
- April 2026 – Lutnick raises the EUV-leak concern in private meetings with ASML leadership.
- April 2026 – ASML circulates an internal briefing titled “No indication of any ASML EUV system in China,” noting 314 operational EUV machines worldwide and none in China.
- June 18 2026 – Bloomberg and Reuters report the U.S. concern; ASML’s shares fall 2.3 % in Amsterdam trading.
- June 19 2026 – U.S. officials decline to disclose evidence; Dutch officials reaffirm strict enforcement.
- April 2026 – Congress advances the MATCH Act, proposing a ban on all ASML DUV shipments to China, which would affect roughly 20 % of the company’s 2026 revenue.
Data on EUV Machines and Market Impact
- 314 EUV systems are in active use globally; 26 have been decommissioned.
- ASML expects ? 20 % of 2026 revenue from permitted DUV sales to China.
- The company’s market capitalization is near $700 billion, and its stock has risen about 80 % year-to-date despite the controversy.
Strategic Significance and Potential Consequences
If a full EUV system were operating in China, it would constitute a major breach of export controls designed to limit Beijing’s access to advanced AI-capable chips. The dispute also highlights the tension between U.S. national-security goals and the commercial interests of a European monopoly that underpins the global semiconductor supply chain.
Official Statements & Responses
- ASML spokesperson: “ASML has never shipped an EUV machine to China nor have we shipped to China any component, module or equipment specially designed to be used in an EUV machine.”
- ASML spokesperson: “We recognize the national security considerations behind export control regulations in the US and the Netherlands, and we’re fully committed to complying with all applicable regulations.”
- Dutch Minister Sjoerd Sjoerdsma: “The system is incredibly robust and the export rules as they currently stand are extremely strict, perhaps the strictest in the entire world.”
- U.S. senior officials (anonymous): claim evidence of ASML exporting EUV-related transport equipment to China, but declined to provide documentation.
Criticism & Opposition from the U.S. Administration
Officials allege that ASML may be prioritising short-term profit over national security, citing earlier shipments of DUV tools that preceded formal controls. They assert that the company has not acted in good faith and that evidence of EUV-related exports exists, though the evidence remains undisclosed.
Conflicting Reports & Evidentiary Gaps
- U.S. claim: evidence of EUV-related components shipped to China.
- ASML denial: no EUV machine or dedicated components have been exported; internal monitoring shows continuous connectivity with all EUV units.
- No public proof of an EUV system operating in China has been presented by either side.

- “ASML regularly engages in transparent and open dialogue with government leaders globally,” — ASML spokesperson
- “Any claim that ASML would or did consciously and willingly break any agreement with the Dutch, the US or any other government is not only factually incorrect but significantly misleading,” — ASML spokesperson
What’s Next
Congress is expected to vote on the MATCH Act, which could extend U.S.-level export restrictions to foreign suppliers and ban all ASML DUV shipments to China. The U.S. may also consider leveraging its $150 million investment in the xLight startup as leverage. Until concrete evidence is disclosed, the dispute will remain a focal point of U.S.–EU trade negotiations and semiconductor-policy debates.
