A bipartisan group of U.S. lawmakers is pushing legislation that would compel the Commerce Department to tighten restrictions on semiconductor equipment sales to China, taking direct aim at tools made by Dutch lithography giant ASML and Japan’s Tokyo Electron. The bill, known as the MATCH Act (Multilateral Alignment of Technology Controls on Hardware Act), cleared the House Foreign Affairs Committee in spring 2026 and has a companion version in the Senate, giving it a foothold in both chambers that single-party proposals rarely achieve.
Sponsors say the measure is designed to close gaps in existing export controls that allow Beijing to acquire machines and components used to fabricate advanced chips with military applications. If enacted, the law would mark the first time Congress has written multilateral chip-equipment restrictions into statute, rather than leaving them to executive-branch rulemaking that can shift from one administration to the next.
What the MATCH Act would require
The House version, H.R. 8170, was co-authored by Rep. Michael Baumgartner, a Washington state Republican, and Rep. Raja Krishnamoorthi, an Illinois Democrat. House Foreign Affairs Committee Chair Brian Mast, a Florida Republican, shepherded the bill through markup and called it a necessary step to ensure allied governments coordinate their restrictions on chip-making tools flowing to China.
“We must ensure that the United States and our allies are on the same page when it comes to keeping advanced semiconductor technology out of the hands of the Chinese Communist Party,” Mast said in a committee press release announcing the bill’s advancement.
A Senate companion bill mirrors the House text and carries its own bipartisan sponsorship, signaling that the effort is more than a messaging exercise from a single committee.
The core mechanism is alignment. Rather than relying solely on unilateral U.S. restrictions, the bill directs the Commerce Department to harmonize American controls with those already adopted by Japan and the Netherlands. Japan announced amended export-control rules for semiconductor manufacturing equipment in May 2023, with the restrictions taking effect in July 2023, covering lithography, etching, and deposition tools. The Netherlands enacted parallel restrictions around the same period, targeting ASML’s most advanced extreme ultraviolet (EUV) lithography systems. But sponsors argue that without a formal legislative framework, loopholes persist. China can exploit intermediaries, purchase older-generation tools that still have military utility, or take advantage of timing gaps between when an ally announces new controls and when the U.S. updates its own rules.
Under the MATCH Act, Commerce would be required to review foreign controls, identify divergences, and update U.S. regulations so that key categories of chip-making equipment are treated consistently across major supplier countries. The bill also mandates regular reporting to Congress, giving lawmakers visibility into how closely American rules track with allied restrictions and where gaps remain.
The policy it builds on
The MATCH Act does not emerge from a vacuum. It layers on top of a series of escalating executive-branch actions that began in October 2022, when the Bureau of Industry and Security (BIS) issued sweeping controls on advanced semiconductor technology destined for China. BIS followed up with additional rounds of restrictions, expanded the Entity List with large-scale additions targeting Chinese firms, and issued guidance to address diversion of restricted technology through third countries. The agency has described these measures as efforts to restrict China’s capability to produce advanced semiconductors for military applications.
What the MATCH Act adds is statutory permanence and a congressional oversight hook. Because BIS controls are regulatory, they can be revised or relaxed by any sitting administration without a vote on Capitol Hill. Writing multilateral alignment into law would make it harder for a future president to quietly loosen restrictions, and the reporting requirements would force the executive branch to explain publicly whenever U.S. rules fall out of step with allied controls.
The bipartisan backing is itself notable. In a Congress where technology policy often fractures along party lines over questions of industrial subsidies and trade, both Republicans and Democrats in the House and Senate have signed on. That cross-party support reflects a hardening consensus that advanced semiconductors sit at the center of strategic competition with China, a rare area where the two parties’ instincts converge.
The stakes for ASML and Tokyo Electron
Neither ASML nor Tokyo Electron has issued a public statement responding to the MATCH Act, but the financial stakes are substantial. ASML reported that China accounted for roughly 29% of its total net sales in 2024, making it the company’s largest market by geography. Tokyo Electron has similarly disclosed significant China-derived revenue. Any tightening of multilateral controls would directly affect their order books, particularly for the mature-node tools that currently fall outside the strictest restrictions.
Both companies have already adjusted their operations in response to earlier rounds of Dutch and Japanese controls. ASML stopped shipping its most advanced EUV systems to China, and Tokyo Electron curtailed certain equipment deliveries. But the MATCH Act could go further by pressuring governments to restrict a broader set of tools, including those used for less cutting-edge chip production that still has defense relevance.
Without official corporate filings or earnings guidance addressing the bill, the precise financial impact is not yet quantifiable. Investors and analysts will be watching for commentary during upcoming quarterly earnings calls, where both companies typically address regulatory developments affecting their China business.
Open questions and risks
Several significant uncertainties hang over the legislation. The White House has not publicly indicated whether it supports the MATCH Act or views it as complementary to existing executive-branch controls. A strong endorsement from the administration could accelerate consideration in both chambers; a cooler reception might leave the bill stalled in committee.
The Senate path forward is particularly unclear. While the companion bill’s introduction demonstrates bicameral interest, no public record of a Senate committee markup or floor scheduling has emerged. Legislative momentum in the House does not guarantee matching progress in the upper chamber, where procedural hurdles and competing priorities routinely stall even popular measures.
There is also a strategic tension the bill’s sponsors have not fully addressed in the public record: whether tighter multilateral controls will accelerate China’s push to build a self-sufficient domestic semiconductor supply chain. Beijing has already poured tens of billions of dollars into homegrown chip-making capabilities, and each new round of Western restrictions strengthens the political case within China for massive state-directed spending on alternatives. The MATCH Act bets that denying China access to the best foreign tools now outweighs the risk of spurring longer-term technological decoupling.
Enforcement presents another challenge. The bill assumes that closer alignment with allies will reduce opportunities for circumvention, but the publicly available text does not spell out new penalties or investigative tools beyond those Commerce already wields. Tracking secondhand equipment sales, shell-company purchases, and transfers routed through third countries that do not share Western concerns about Chinese military modernization remains a persistent weak point in the current regime.
Where the chip-equipment fight goes from here
The MATCH Act represents a legislative attempt to harden and internationalize a policy trajectory that is already well underway. Its strongest evidence base comes from primary government sources: the bill text available through the Government Publishing Office, the House Foreign Affairs Committee’s official press release, and BIS documentation of the executive-branch controls the legislation seeks to reinforce.
What the public record does not yet include is equally important: no classified Commerce Department assessments of current diversion rates, no corporate filings from ASML or Tokyo Electron addressing the bill, and no White House position statement. The gap between clear legislative intent and uncertain real-world outcomes is where the story will develop in the months ahead, as the bill moves (or stalls) through Congress and the companies at its center decide how to respond.
