Order No. 834 Puts ASML's Service Contracts Under Chinese Law
Order No. 834 authorizes investment bans and import-export restrictions against companies enforcing foreign supply-chain controls on Chinese entities. For ASML, whose Chinese service rounds completed in Q1, the September allied-alignment deadline falls inside the next maintenance window.
China's State Council published Order No. 834 on March 31, authorizing countermeasures against companies that enforce foreign supply-chain restrictions on Chinese entities. As Donald Trump arrived in Beijing on May 13 for a summit with Xi Jinping, the Foreign Ministry named the target. Spokesperson Lin Jian called the MATCH Act "malicious blocking and suppression" of Chinese industry.
The MATCH Act cleared the House Foreign Affairs Committee 36 to 8 on April 22. It names five covered facilities: SMIC, Huawei, Hua Hong, ChangXin Memory Technologies, and Yangtze Memory Technologies, plus all subsidiaries. The bill still requires a full House floor vote and Senate passage before it becomes law; the 150-day allied-alignment clock runs from enactment, not committee approval.
The technical threshold is overlay accuracy at or below 2.4 nanometers, which captures ASML's NXT:1980Fi. SMIC has used that machine through multiple-exposure patterning to produce 7-nanometer chips for Huawei despite prior Dutch export restrictions. Under the bill's terms, any service call, spare-parts shipment, or technical-support visit to a covered facility would require a U.S. government license.
What Is Running
An April 2026 AEI analysis estimates that Chinese entities acquired roughly 90 NXT:1980Fi-class machines in 2024, worth approximately $5 to $7 billion. That represented close to 70 percent of ASML's global DUV immersion output that year. AEI puts China's total DUVi fleet, including machines acquired in prior years, at "several hundred," a cumulative count ASML has never broken out by facility.
Each machine runs on an approximately six-month maintenance cycle. Chinese fabs have sourced grey-market parts and hired independent engineers for subsystem work, but factory-level calibration still requires ASML. Service rounds that completed in Q1 put the next Chinese maintenance window in July, before the September 19 allied-alignment deadline.
Two Clocks
The legislation gives the Netherlands and Japan 150 days, from enactment, to align their export rules with Washington's. Both countries produce semiconductor equipment at scale. If either fails, the Foreign Direct Product Rule applies: any ASML machine built with U.S. components or software becomes subject to U.S. export law, wherever manufactured.
Order No. 834's Article 15 authorizes Chinese regulators to bar a non-compliant company from investing in China and to restrict its import and export privileges. The companion Decree No. 835, signed the same day, adds a Malicious Entities List that can block a firm from Chinese government procurement and impose fines. MOFCOM issued its first blocking order under the related 2021 Blocking Rules on May 2, 2026, establishing a precedent the broader countermeasure regime had not previously produced.
A company complying with the MATCH Act's service ban would satisfy Order No. 834's trigger criteria. Beijing has separately restricted exports of gallium, germanium, antimony, and rare earths, and issued a rule requiring domestic chipmakers to source half of new equipment from Chinese suppliers.
The service-ban provision changes the math on ASML's China exposure. The company reported €2.5 billion in installed-base management revenue in Q1 2026, a global figure not broken out by geography. That denominator, which ASML has not published and no regulator has forced out, is how many of China's "several hundred" DUVi machines sit at the five covered facilities.
ASML's Q2 2026 earnings call, expected in mid-July, arrives eight weeks before the September 19 deadline. Watch the installed-base management line: €2.5 billion in Q1. Any downward revision in Q3 guidance is ASML pricing in the service cliff the Q1 filings left unaddressed.
