Ahem, ASML, who makes the manufacturing equipment for TSMC is a Dutch company, not a US one.

The UV light source that ASML uses for its lithography machine is technology that was acquired in the 2013 acquisition of San Diego-based Cymber. The tech stack for the advanced light source dates back to the "EUV LLC Initiative," led by DARPA in the mid-1990s.

US origins of the key technology here give the US a veto here regardless of ASML's Dutch headquarters.

Is this an actual thing? Genuinely asking. Not that rules and laws seem to matter anymore to the current US administration anyway

		Yes, the mechanism is effectively EAR/FDPR and you can check (https://en.wikipedia.org/wiki/Extreme_ultraviolet_lithograph...) for more detailed history, but the EUV technology ASML further developed and commercialized (no small feat) was licensed from a US Govt created consortium by which the government maintains their IP rights.

First sale doctrine called, reminded about itself.
