Taiwan Semiconductor Manufacturing Co (TSMC) could face a penalty of US$1 billion or more to settle a US export control investigation over a chip it made that ended up inside a Huawei artificial intelligence (AI) processor, two people familiar with the matter said.
The US Department of Commerce has been investigating the world's biggest contract chipmaker's work for China-based Sophgo, the sources said.

The design company's TSMC-made chip matched one found in Huawei's high-end Ascend 910B AI processor, according to the people, who requested anonymity because they were not authorized to speak publicly about the matter.
Huawei — a company at the center of China's AI chip ambitions that has been accused of sanctions busting and trade secret theft — is on a US trade list that restricts it from receiving goods made with US technology.
TSMC made nearly 3 million chips in recent years that matched the design ordered by Sophgo and likely ended up with Huawei, according to Lennart Heim, a researcher at RAND's Technology and Security and Policy Center in Arlington, Virginia, who is tracking Chinese developments in AI.
The US$1 billion-plus potential penalty comes from export control regulations allowing for a fine of up to twice the value of transactions that contravene the rules, the sources said.
Because TSMC's chipmaking equipment includes US technology, the company's Taiwan factories are within reach of US export controls that prevent it from making chips for Huawei, or producing certain advanced chips for any customer in China without a US license.
Heim said that based on the design, which is for AI applications, TSMC should not have made the chip for a company headquartered in China, especially given the risk that it could be diverted to a restricted entity like Huawei.
Reuters could not determine how the White House is to proceed with TSMC or when the matter would be resolved.
Top officials have said they plan to seek higher penalties for export violations.
A spokesperson for the commerce department declined comment.
TSMC spokesperson Nina Kao (高孟華) said in a statement that the company is committed to complying with the law.
She added that TSMC has not supplied to Huawei since mid-September 2020 and that they are cooperating with the department.
Speaking to reporters in Taipei today, Minister of Economic Affairs J.W. Kuo (郭智輝) said that TSMC is a company that respects laws and regulations, but his ministry has not received any notification about a possible fine and he could not comment further.
No public action has been taken against TSMC.
The department typically issues a "proposed charging letter" to a company it believes has engaged in prohibited conduct.
The letter usually cites the dates alleged contraventions took place, the value and the formula for a civil penalty, and it gives the company 30 days to respond.
Taipei has once again made it to the top 100 in Oxford Economics’ Global Cities Index 2025 report, moving up five places from last year to 60. The annual index, which was published last month, evaluated 1,000 of the most populated metropolises based on five indices — economics, human capital, quality of life, environment and governance. New York maintained its top spot this year, placing first in the economics index thanks to the strength of its vibrant financial industry and economic stability. Taipei ranked 263rd in economics, 44th in human capital, 15th in quality of life, 284th for environment and 75th in governance,
The Sports Administration yesterday demanded an apology from the national table tennis association for barring 17-year-old Yeh Yi-tian (葉伊恬) from competing in the upcoming World Table Tennis (WTT) United States Smash tournament in Las Vegas this July. The sports agency said in a statement that the Chinese Taipei Table Tennis Association (CTTTA) must explain to the public why it withdrew Yeh from the WTT tournament in Las Vegas. The sports agency said it contacted the association to express its disapproval of the decision-making process after receiving a complaint from Yeh’s coach, Chuang
Control Yuan Secretary-General Lee Chun-yi (李俊俋) tendered his resignation last night, admitting that he had misused a government vehicle, as reported by media. His resignation was immediately accepted by the Control Yuan. In a statement explaining why he had resigned, Lee apologized for using a Control Yuan vehicle to transport his dog to a pet grooming salon on May 20. The issue first came to light late last month, when TVBS News reported that Lee had instructed his driver to take the dog to the salon. The news channel broadcast photos that it said were taken by an unnamed whistle-blower, which purportedly showed the
A former officer in China’s People’s Liberation Army (PLA) who witnessed the aftermath of the 1989 Tiananmen Square massacre has warned that Taiwan could face a similar fate if China attempts to unify the country by force. Li Xiaoming (李曉明), who was deployed to Beijing as a junior officer during the crackdown, said Taiwanese people should study the massacre carefully, because it offers a glimpse of what Beijing is willing to do to suppress dissent. “What happened in Tiananmen Square could happen in Taiwan too,” Li told CNA in a May 22 interview, ahead of the massacre’s 36th anniversary. “If Taiwanese students or
