Export rules reshape chip markets
- U.S. officials said Nvidia has not yet sold H200 AI chips to China, illustrating persistent export frictions. - Lawmakers are pushing the MATCH Act to limit Commerce Department discretion over chip-export controls, including DUV lithography tools. - Combined with Micron’s lobbying for equipment restrictions, policy moves are actively reshaping where advanced hardware can be sold and produced (reuters.com) (tomshardware.com) (telecom.economictimes.indiatimes.com).
Nvidia’s H200 artificial-intelligence chip still has not reached Chinese buyers, even after Washington cleared some sales in January. (usnews.com) Commerce Secretary Howard Lutnick said on April 22 that Chinese companies have not bought the chip because Beijing has not yet allowed the purchases. Reuters reported the Trump administration had given formal approval in January, but shipments were later stalled by disputes over sale terms in both China and the United States. (usnews.com) At the same time, Congress is moving to tighten the rules on the machines used to make chips. The proposed MATCH Act was introduced in the House on April 2 and in the Senate on April 8 as bipartisan legislation aimed at “chokepoint” semiconductor tools that U.S. rivals cannot build on their own. (baumgartner.house.gov) (foreign.senate.gov) The bill reaches beyond Nvidia-style processors to factory gear such as deep ultraviolet immersion lithography machines, which use light to print circuit patterns onto silicon. Reuters reported the draft would restrict those machines nationwide in China and require licenses for foreign companies, including ASML, to service covered equipment at targeted fabs. (taipeitimes.com) Micron has been one of the companies pressing lawmakers to move faster. Reuters reported on April 23 that the U.S. memory-chip maker has argued Washington should do more to slow Chinese memory producers including Yangtze Memory Technologies Corp. and ChangXin Memory Technologies. (taipeitimes.com) That fight is about manufacturing capacity as much as finished chips. The House measure targets facilities tied to ChangXin, Yangtze Memory and Semiconductor Manufacturing International Corp., and a House Foreign Affairs Committee staffer described the broader package of export-control bills as the biggest legislative push since the Export Control Reform Act of 2018. (taipeitimes.com) Supporters of the MATCH Act say current controls leave U.S. companies at a disadvantage when allies do not match them. Senate sponsors said the bill would harmonize export controls with partners, close servicing loopholes and stop front-company workarounds that let Beijing keep buying critical chipmaking gear. (foreign.senate.gov) The result is a chip market shaped less by product demand than by licenses, service contracts and allied coordination. Nvidia’s unsold H200s and Congress’s push to control lithography tools show that access to semiconductors now depends on who can ship them, who can maintain them and which governments agree.
