The lede. Everyone treats ASML like a U.S. policy target. It isn't, directly — the U.S. can't order a Dutch company to stop shipping. ASML's EUV machines (used for the most advanced chips) have never been sold to China anyway, blocked since 2019 under Dutch export-licensing rules adopted after sustained U.S. diplomatic pressure, not U.S. law. The real mechanism is the Commerce Department's Foreign Direct Product Rule and its allied-coordination architecture: Washington leans on The Hague, The Hague's Ministry of Foreign Affairs sets ASML's export license list, and that list — not any U.S. statute — decides which older DUV immersion tools ASML can still ship into China. Every ratchet tightens through a bilateral channel, and every loosening (or delay) is a diplomatic event, not a regulatory one. That makes ASML a pure-play bet on the durability of U.S.-Dutch alignment — and a leading indicator for the entire equipment sector, because when Dutch licensing tightens, Beijing accelerates domestic substitution spending that flows straight to ASML's suppliers' rivals and to ASML's own domestic-China competitors' targets.
