On April 2, 2026, a bipartisan group of US lawmakers introduced the Multilateral Alignment of Technology Controls on Hardware Act — the MATCH Act — in both the House and Senate simultaneously. The legislation marks the first time Congress, rather than the White House, has driven semiconductor export controls against China. It closes three critical gaps that have allowed Chinese chipmakers to continue advancing despite years of restrictions: it extends bans from advanced EUV lithography to older DUV immersion systems that ASML still sells at scale, it prohibits the servicing and maintenance of installed equipment at designated Chinese facilities, and it gives US allies 150 days to implement equivalent controls or face unilateral American enforcement. The bill names five Chinese national champions — SMIC, Hua Hong, Huawei, CXMT, and YMTC — applying Entity List-level restrictions to all their facilities, subsidiaries, and affiliates. Co-sponsored by the chairman of the Select Committee on China, Senate leaders from both parties including Chuck Schumer, and endorsed by the Council on Foreign Relations, FDD Action, and the Foundation for American Innovation, the MATCH Act represents the most comprehensive attempt to convert semiconductor equipment from a theoretical chokepoint into an operational one. ASML shares fell on the news — China accounted for 33% of its 2025 revenue.
The MATCH Act closes three gaps that have allowed Chinese chipmakers to continue advancing despite four years of escalating export controls. The first gap is technology scope: existing restrictions block ASML's most advanced extreme ultraviolet lithography systems, but China's largest chipmakers — including SMIC — have continued purchasing older deep ultraviolet immersion lithography tools at scale.[4] SMIC demonstrated 7nm-equivalent chip production using DUV multi-patterning, proving that the technology the controls left unrestricted was sufficient for commercially and militarily relevant semiconductor manufacturing.[10] The MATCH Act extends the ban to DUV immersion systems, closing the technology gap that made the existing controls partially effective at best.
The second gap is servicing. Manufacturing tools are not static machines — they require continuous calibration, parts supply, software updates, and technical support to maintain process stability and yield.[6] Previous controls restricted sales of new equipment but left servicing of installed systems largely intact. The MATCH Act prohibits maintenance, transforming every ASML DUV system already operating in a designated Chinese facility into a depreciating asset. Without servicing, yield degrades, process drift increases, and production capacity erodes within months — not years.[5]
The third gap is allied alignment. US unilateral controls have consistently been stricter than those of the Netherlands and Japan — the only other countries with significant semiconductor equipment industries. This asymmetry created a competitive disadvantage for American firms while allowing allied companies to continue selling to China. The MATCH Act addresses this directly: allies have 150 days to demonstrate equivalent controls, or the Department of Commerce implements restrictions unilaterally using US technology jurisdiction over foreign-made products containing American software, technology, or components.[1][2][3]

The MATCH Act is not an executive order — it is bipartisan legislation with simultaneous introduction in both chambers. In the House, Representative Michael Baumgartner leads with 10 original co-sponsors including Select Committee on China Chairman John Moolenaar, members from both parties, and representation spanning Washington, Michigan, Georgia, Indiana, New York, Maine, New Hampshire, and Virginia.[1] In the Senate, Pete Ricketts and Andy Kim lead with co-sponsors Jim Risch — chairman of the Senate Foreign Relations Committee — and Chuck Schumer, the Senate Democratic Leader.[3] The breadth of sponsorship signals durable political consensus: this is not a partisan initiative that changes with administrations. The bill has been endorsed by the Council on Foreign Relations, FDD Action, the Foundation for American Innovation, and the Institute for Progress — spanning the think tank spectrum from security hawks to innovation policy advocates.[2] The legislative approach matters because it makes semiconductor export controls statutory rather than regulatory, requiring Congressional action to reverse rather than a simple executive pen stroke.
Export controls on chipmaking tools have been critical to maintaining the U.S. lead in AI computing power. By strengthening chipmaking tool controls, the MATCH Act would better preserve U.S. AI leadership over the long term. — Institute for Progress[2]

|---|---|
| Regulatory (D4) Origin · 75 | First time Congress — not the White House — drives semiconductor export controls. Bipartisan House bill (Baumgartner + 10 co-sponsors including Select Committee on China chairman Moolenaar) with Senate companion (Ricketts, Kim, Risch, Schumer). Country-wide prohibition on chokepoint SME. Entity List-level restrictions on SMIC, Hua Hong, Huawei, CXMT, YMTC including all subsidiaries. 150-day ally compliance deadline with unilateral enforcement fallback. Endorsed by CFR, FDD Action, Foundation for American Innovation, Institute for Progress.[1][2][3]Congressional First |
| Operational (D6) Origin · 72 | Servicing ban is the escalation that changes the game. Manufacturing tools require continuous calibration, parts supply, and technical support — without it, process stability degrades within months. The bill restricts not just new sales but maintenance of installed DUV systems. Extends controls from EUV to DUV immersion lithography — the technology China cannot build domestically and sources primarily from ASML with some from Nikon. At SEMICON China 2026, ASML and Applied Materials kept low profiles while domestic Chinese suppliers dominated visibility.[4][5][6]Servicing Chokepoint |
| Revenue (D3) L1 · 70 | ASML shares fell 2.6% on the news. China was ASML's largest market in 2025 at 33% of €32.7B revenue. Company already projected decline to 20% in 2026 before MATCH Act. Analysts estimate DUV immersion tools represent 10-15% of overall ASML sales with China approximately 50% of that segment — a 5% revenue hit that depreciates over time. Lam Research, Applied Materials, KLA, and Tokyo Electron also exposed. Chinese chipmakers posted record revenues in 2025 but face equipment replacement cycle risk.[7][8]33% Revenue Exposure |
| Customer (D1) L1 · 65 | Five Chinese national champions explicitly designated: SMIC (China's largest foundry), Hua Hong (specialty/analog), Huawei (integrated device manufacturer), CXMT (DRAM), YMTC (NAND flash). All subsidiaries and affiliates included. Restrictions cover exports, servicing, and technical support — Entity List-equivalent treatment. These firms have been adapting through stockpiling, DUV multi-patterning innovation, and domestic equipment development, but remain dependent on Western servicing for installed base.[2][3][9]Named Targets |
| Quality (D5) L2 · 58 | China's domestic semiconductor equipment industry is growing rapidly — domestic suppliers dominated SEMICON China 2026. SMIC demonstrated 7nm-equivalent production using DUV multi-patterning. Chinese chipmakers posted record revenues. But quality gap persists: no domestic EUV capability, DUV alternatives lag ASML by years, and servicing loss would degrade existing process stability. The MATCH Act targets the gap between China's ambition and its current dependency.[4][10]Domestic Surge, Quality Gap |
| Employee (D2) L2 · 52 | ASML employs thousands in China for sales and servicing — servicing ban puts these roles at risk. Nexperia's China unit reportedly instructed local employees to disregard Dutch headquarters. Chinese fab workforce faces uncertainty as installed equipment degrades. US semiconductor workforce benefits from reshoring incentives. Bill explicitly aims to ensure 'jobs happen in the United States and allied countries, not China.'[5][11]Cross-Border Workforce Strain |
The MATCH Act does not exist in a vacuum. China deployed its own version of the foreign direct product rule on rare earth materials in October 2025, requiring export licenses for products containing even trace amounts of Chinese-origin rare earths — including those used in semiconductor manufacturing equipment.[8] The one-year Busan agreement that suspended both sides' escalatory measures expires in November 2026. Rare earth concentrate prices have risen over 50% since late 2024, with Baogang Group and Northern Rare Earth announcing 37% price increases for Q4 2025.[11] In January 2026, China halted rare earth exports to Japanese firms in retaliation for Tokyo's Taiwan stance — a preview of the targeted counter-measures available if the MATCH Act passes.[12] At SEMICON China 2026, the floor told the story: ASML and Applied Materials kept low profiles while domestic Chinese suppliers dominated visibility and presence.[4] Chinese chipmakers posted record revenues in 2025 despite existing restrictions. The structural question the MATCH Act poses is whether closing the last loopholes accelerates Chinese self-sufficiency — which is already advancing — or constrains it at the critical DUV threshold where domestic alternatives remain years behind.[10]

Previous export controls focused on blocking new equipment sales. The MATCH Act targets the installed base. Semiconductor manufacturing tools require continuous calibration, parts replacement, and technical support — without servicing, process stability degrades within months. By prohibiting maintenance, the bill turns every ASML DUV system already operating in a Chinese fab into a depreciating asset on a countdown clock. This is the difference between denying new capability and degrading existing capability.
Every previous round of semiconductor export controls was driven by the executive branch — Biden's October 2022 rules, Trump's Affiliates Rule extension. The MATCH Act originates from Congress with bipartisan House and Senate companion bills and Chuck Schumer's co-sponsorship. This means export controls become statutory rather than regulatory, harder to reverse through executive action, and signal to allies and adversaries alike that the chokepoint strategy has durable political consensus.
The bill gives US allies — primarily the Netherlands and Japan — 150 days to demonstrate equivalent controls. If they fail, the Department of Commerce implements restrictions unilaterally using US technology jurisdiction over foreign-made products containing American components. This transforms semiconductor diplomacy from negotiation to deadline. The Netherlands has been cautious in matching US restrictions. Japan has been narrower. Neither has addressed servicing. The MATCH Act forces a choice: align or lose control of the process.
China deployed its own foreign direct product rule (FDPR) on rare earth materials in October 2025, requiring export licenses for products containing even 0.1% Chinese-origin rare earths. The one-year Busan agreement suspension expires November 2026. Rare earth concentrate prices rose 50%+ since late 2024. At SEMICON China 2026, domestic Chinese equipment suppliers dominated floor presence while ASML kept a low profile. The MATCH Act accelerates both the chokepoint tightening and the counter-cascade — the question is which timeline moves faster.
