US President Joe Biden’s administration next month plans to broaden curbs on US shipments to China of semiconductors used for artificial intelligence (AI) and chipmaking tools, several people familiar with the matter said.
The US Department of Commerce intends to publish new regulations based on restrictions communicated in letters earlier this year to three US companies — KLA Corp, Lam Research Corp and Applied Materials Inc, the people said, speaking on the condition of anonymity.

The letters, which the companies publicly acknowledged, forbade them from exporting chipmaking equipment to Chinese factories that produce advanced semiconductors with sub-14 nanometer processes unless the sellers obtain commerce department licenses.
The rules would also codify restrictions in commerce department letters sent last month to Nvidia Corp and Advanced Micro Devices Inc (AMD) instructing them to halt shipments of several AI computing chips to China unless they obtain licenses.
Some of the sources said the regulations would likely include additional actions against China. The restrictions could also be changed and the rules published later than expected.
So-called “is informed” letters allow the department to bypass lengthy rule-writing processes to put controls in place quickly, but the letters only apply to the companies that receive them.
Turning the letters into rules would broaden their reach and could subject other US companies producing similar technology to the restrictions. The regulations could potentially apply to companies trying to challenge Nvidia and AMD’s dominance in AI chips.
Intel Corp and start-ups like Cerebras Systems Inc are targeting the same advanced computing markets. Intel said it is closely monitoring the situation, while Cerebras declined to comment.
One source said that the rules could also impose license requirements on shipments to China of products that contain the targeted chips. Dell Technologies Inc, Hewlett Packard Enterprise (HPE) and Super Micro Computer Inc make data center servers that contain Nvidia’s A100 chip.
Dell and HPE said they were monitoring the situation, while Super Micro Computer did not respond to a request for comment.
A senior department official declined to comment on the upcoming action, but said: “As a general rule, we look to codify any restrictions that are in is-informed letters with a regulatory change.”
A department spokesperson on Friday declined to comment on specific regulations, but reiterated that the department is “taking a comprehensive approach to implement additional actions ... to protect US national security and foreign policy interests,” including to keep China from acquiring US technology applicable to military modernization.
KLA, Applied Materials and Nvidia declined to comment, while Lam did not respond to requests for comment.
AMD did not comment on the specific policy move, but reaffirmed it does not foresee a “material impact” from its new licensing requirement.
The planned action comes as Biden’s administration has sought to thwart China’s advances by targeting technologies where the US still maintains dominance.
“The strategy is to choke off China and they have discovered that chips are a choke point. They can’t make this stuff; they can’t make the manufacturing equipment,” said Jim Lewis, a technology expert at the Center for Strategic and International Studies. “That will change.”
In an update on China-related measures last week, the Chamber of Commerce, a US business lobbying group, warned members of imminent restrictions on AI chips and chipmaking tools.
“We are now hearing that members should expect a series of rules or perhaps an overarching rule prior to the mid-term election to codify the guidance in recently issued [commerce department] ‘is-informed’ letters to chip equipment and chip design companies,” the chamber said.
The group also said the agency plans to add additional Chinese supercomputing entities to a trade blacklist.
Reuters was first to report in July that the Biden administration was actively discussing banning exports of chipmaking tools to Chinese factories that make advanced semiconductors at the 14-nanometer node and smaller.
US officials have reached out to allies to lobby them to enact similar policies so that foreign companies would not be able to sell technology to China that US firms would be barred from shipping, two of the sources said.
“Coordination with allies is key to maximizing effectiveness and minimizing unintended consequences,” Clete Willems, a trade official at former US president Donald Trump’s administration said. “This should favor broader regulations that others can replicate instead of one-off ‘is informed’ letters.”
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, yesterday said its materials management head, Vanessa Lee (李文如), had tendered her resignation for personal reasons. The personnel adjustment takes effect tomorrow, TSMC said in a statement. The latest development came one month after Lee reportedly took leave from the middle of last month. Cliff Hou (侯永清), senior vice president and deputy cochief operating officer, is to concurrently take on the role of head of the materials management division, which has been under his supervision, TSMC said. Lee, who joined TSMC in 2022, was appointed senior director of materials management and
Gudeng Precision Industrial Co (家登精密), the sole extreme ultraviolet pod supplier to Taiwan Semiconductor Manufacturing Co (台積電), yesterday said it has trimmed its revenue growth target for this year as US tariffs are likely to depress customer demand and weigh on the whole supply chain. Gudeng’s remarks came after the US on Monday notified 14 countries, including Japan and South Korea, of new tariff rates that are set to take effect on Aug. 1. Taiwan is still negotiating for a rate lower than the 32 percent “reciprocal” tariffs announced by the US in April, which it later postponed to today. The
MAJOR CONTRIBUTOR: Revenue from AI servers made up more than 50 percent of Wistron’s total server revenue in the second quarter, the company said Wistron Corp (緯創) on Tuesday reported a 135.6 percent year-on-year surge in revenue for last month, driven by strong demand for artificial intelligence (AI) servers, with the momentum expected to extend into the third quarter. Revenue last month reached NT$209.18 billion (US$7.2 billion), a record high for June, bringing second-quarter revenue to NT$551.29 billion, a 129.47 percent annual increase, the company said. Revenue in the first half of the year totaled NT$897.77 billion, up 87.36 percent from a year earlier and also a record high for the period, it said. The company remains cautiously optimistic about AI server shipments in the third quarter,
Nvidia Corp CEO Jensen Huang (黃仁勳) on Thursday met with US President Donald Trump at the White House, days before a planned trip to China by the head of the world’s most valuable chipmaker, people familiar with the matter said. Details of what the two men discussed were not immediately available, and the people familiar with the meeting declined to elaborate on the agenda. Spokespeople for the White House had no immediate comment. Nvidia declined to comment. Nvidia’s CEO has been vocal about the need for US companies to access the world’s largest semiconductor market and is a frequent visitor to China.
