US Commerce Concerns Over ASML’s EUV Equipment: A Matter of Global Importance
According to Bloomberg, US Commerce Secretary Howard Lutnick recently told senior ASML executives in a series of meetings that he was concerned that one of the Dutch chipmaker’s extreme ultraviolet lithography machines – the EUV systems, which are the only tools on Earth capable of printing the most advanced semiconductor patterns – may have ended up in China. That would be a serious violation of export controls that have prevented ASML from selling EUV to China since the first Trump administration.
It’s a serious claim. Senior administration officials told Bloomberg that they have evidence that ASML has shipped EUV-related components and transportation equipment to China, although they have repeatedly refused to show it – either to Bloomberg or, apparently, to ASML itself. The company says there is no such machine in China and never has been. The Commerce Department did not respond to Bloomberg’s questions about whether it had evidence of an actual EUV system on Chinese soil.
The Strategic Importance of ASML
You might think this isn’t worth paying attention to if you’re not in the chip industry, but it is. ASML is a Dutch company that most people have never heard of, but it is by far the most important company in global AI construction not called Nvidia or one of the hyperscalers. This makes them the only machines on the planet capable of performing EUV lithography – the process of printing the microscopic circuit patterns that define the most advanced chips.
Every cutting-edge processor from TSMC, the manufacturer behind Nvidia and Apple’s chips, relies on ASML tools that the company has invested some two decades and untold billions to develop. There is currently no second provider. That monopoly has made ASML Europe’s most valuable listed company, with a market capitalization that stood at about $700 billion this week, which has surged over the past year due to insatiable demand for AI-driven chips.
Potential Implications of Export Control Violations
It is precisely this magnitude that makes the China issue so important. If even one EUV machine ends up in Chinese hands, it would be one of the most serious violations of the export control system that the US has built in recent years to keep advanced AI capabilities out of Beijing’s military and industrial base.
I sat down with ASML CEO Christophe Fouquet six weeks ago, long before this story broke, and asked him directly about the China question.
Fouquet told me that ASML tracks every machine ever delivered – it is either actively in use with monitored customers or has been dismantled and returned to the company. He said the company built an internal firewall years ago: Employees who can access EUV technology, documentation and training are walled off from those who cannot, and ASML’s China-based employees are intentionally sitting on the wrong side of that wall. He argued that the only reason ASML could build an EUV machine at all is that 80% of it already consists of decades of prior knowledge and that solving the one truly new problem – the production of EUV light itself – alone took 20 years. His broader point seemed to be that you can’t reverse engineer a machine you’ve never had, and no one in China had one.
Commercial Logic and Strategic Calculations
There is also a simpler commercial logic that contradicts the idea that ASML would risk its export license to quietly arm a Chinese customer. ASML does sell older-generation deep ultraviolet equipment to China – the equipment was first shipped a decade ago – but Fouquet specifically called this a protection calculation, not a loophole. The idea, he suggested, is to keep the generation gap wide enough to allow customers to continue doing business – but without creating a future competitor of their own. ASML expects about 20% of its revenue in 2026 to come from already approved sales to China. Risking the EUV ban entirely would jeopardize these revenues and the company’s position as the most valuable monopoly in European industry through a single illegal sale.
None of this proves the claims are false. The government has not yet released its evidence, and it is worth holding off on judgment until it does.
Emerging Technological Competition
The Commerce Department under Lutnick’s leadership agreed late last year to pour up to $150 million in taxpayer money into xLight, a startup developing next-generation light source technology described as a long-term challenge to the core of ASML’s EUV monopoly. xLight’s CEO himself told me last year that the company sees itself as a future partner of ASML rather than a rival, and is building hardware to integrate with ASML’s machines rather than replace them. When I presented this framework to Fouquet in May, he was polite but unconvinced; ASML, he made clear, does not see itself needing xLight’s technology to maintain its lead.
Does this have anything to do with why Lutnick is suddenly pushing ASML over EUV? Nothing public connects the two. It could be completely unrelated. But it’s worth investigating a federal official who is probing a monopoly while his own agency is pouring money into a startup that aims to improve that monopoly’s core technology.
xLight isn’t the only outside bet on the future of lithography. Peter Thiel – long associated with Trump’s political influence – has backed Substrate, a separate startup that is explicitly pursuing its own EUV competitor technology and has ambitions to compete more directly with ASML than xLight intends to.
Legislative Developments and Future Implications
As Bloomberg notes, a bipartisan bill before Congress would go much further than EUV – it calls for an effective ban on all deep ultraviolet (DUV) ASML shipments to China, the less advanced lithography equipment that accounts for about a fifth of the company’s expected sales in 2026. The bill was approved by a key committee in April and the Trump administration has not yet issued a formal statement on it.
