ASML Denies US Claims of EUV Machine Presence in China
In brief
- ASML confirmed zero EUV machine shipments to China since 2019 export restrictions began
- US Commerce Secretary Howard Lutnick raised concerns about unauthorized transfer during June 2026 meetings
- Each EUV machine costs $150–$400 million with over 100,000 proprietary components requiring ASML maintenance
- US officials provided no concrete evidence supporting the alleged transfer claim
- EUV systems are critical for advanced chip manufacturing in AI, computing, and defense applications
The stakes of semiconductor control
EUV systems are essential for manufacturing the most advanced semiconductor chips, the kind powering AI training clusters, high-performance computing, and military applications. Each machine costs between $150 million and $400 million, contains over 100,000 components, and requires ongoing proprietary maintenance from ASML itself. That combination of cost, complexity, and technical dependency makes EUV technology one of the most tightly controlled assets in global supply chains.
ASML's customer list includes TSMC, Samsung, and Intel, all of which rely on the company's EUV systems to manufacture advanced processors. No other manufacturer exists. That monopoly position makes ASML central to US-China tech competition and the subject of intense diplomatic pressure.
Denial without evidence
No concrete evidence supporting the alleged transfer has been provided by US officials. ASML's statement is unambiguous: the company has shipped zero EUV machines to Chinese clients since 2019. The Dutch government's export ban, enacted under significant US pressure, has held for seven years.
Chinese firms can still acquire older deep ultraviolet (DUV) lithography systems, though even those sales face increasingly rigorous controls. But the jump from DUV to EUV represents a generational leap in chip-making capability—one that ASML says it has not enabled for any Chinese customer.
The geopolitical framing is clear. US officials flagged the concern. ASML denied it. No documents, no intercepted communications, no third-party verification has emerged to bridge that gap. For now, the Dutch chipmaking monopoly stands by its compliance record, and the export controls remain in place.
