Washington tells ASML an EUV tool is in China; ASML counts all 314 and says no

Lutnick alleges EUV-related components and transport gear reached China; ASML insists no system or EUV-specific part was ever delivered, as BIS enforcement looms

Summary

US Commerce Secretary Howard Lutnick has told ASML that an Asml extreme-ultraviolet (EUV) lithography tool, or EUV-related parts, reached China in breach of Dutch and US export controls. The claim surfaced publicly on 18-19 June via Bloomberg and TechCrunch; by 22 June, US officials specified the evidence concerns EUV-compatible components and transport equipment, not a complete machine. ASML rebutted in unusually explicit terms: it delivered neither a complete EUV system nor any component specifically developed for EUV to China, and says all 314 of its installed EUV systems are accounted for. The Netherlands has barred EUV exports to China since 2019. Officials have repeatedly declined to share the evidence, raising the prospect of BIS enforcement, the agency settled with Applied Materials for $252.5M in February over parts routed to Smic.

By the numbers

  • 314, installed ASML EUV systems the company says it can fully account for.
  • 0, EUV machines ASML says it has shipped to China since the 2019 Dutch ban.
  • ~20%, share of ASML's 2026 revenue from previously approved (non-EUV) China sales.
  • $252.5M, BIS penalty on Applied Materials (Feb 2026) for parts routed via Korea to SMIC.
  • 60+, EUV units ASML plans to ship in 2026 (80 in 2027, incl. ~10 High-NA scanners).

Why it matters

A confirmed EUV breach would shatter the central assumption of the chip-control regime, that the single most restricted tool cannot reach China. The component-vs-machine distinction is the whole case: dual-use parts sit in a grey zone the controls were not written for. Unproven, the row still pressures ASML's China revenue and Dutch-US alignment.

What to watch

  • Whether BIS opens a formal enforcement action and finally produces evidence.
  • ASML's response on the next earnings call and any China-revenue guidance cut.
  • Dutch government posture, whether The Hague backs ASML or Washington.
