The Office of the US Trade Representative is to hold a hearing tomorrow into older Chinese-made “legacy” semiconductors that could heap more US tariffs on chips from China that power everyday goods from cars to washing machines to telecoms equipment.
The probe, which began during former US president Joe Biden’s tenure in December last year, aims to protect US and other semiconductor producers from China’s massive state-driven buildup of domestic chip supply. A 50 percent US tariff on Chinese semiconductors began on Jan. 1.

The US Department of Commerce in December last year said that two-thirds of US products using chips had Chinese legacy chips in them, and half of US companies did not know the origin of their chips including some in the defense industry.
The hearing comes as US President Donald Trump has called for the repeal of a US$52.7 billion law to boost US chips manufacturing. The CHIPS and Science Act, which the US Congress passed in 2022, has made awards to Intel Corp, Samsung Electronics Co, Micron Technology Inc, Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and others.
The probe is being conducted under Section 301 of the Trade Act of 1974, the same unfair trade practices statute Trump invoked to impose tariffs of up to 25 percent on about US$370 billion worth of Chinese imports in 2018 and 2019.
Separately, Trump softened his stance on Taiwan’s semiconductor industry on Friday, just days after TSMC announced a US$100 billion investment in the US.
Speaking at the White House, Trump reiterated that Taiwan “stole” the US chip industry, but shifted the blame to previous administrations for allowing the computer chip production to move overseas.
“They stole it from us. They took it from us, and I don’t blame them. I give them credit,” Trump said. “I blame the people that were sitting in this seat because they allowed it to happen.”
Previously, Trump had threatened a 100 percent tariff on Taiwan’s semiconductor imports to the US, to encourage domestic chip production.
Trump hailed TSMC’s expansion as a major victory for the US because his government did not have to offer any subsidies, and criticized the CHIPS Act, calling it a waste of money.
He said that TSMC’s investment was driven by concerns over tariffs, rather than US government incentives.

Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) would not produce its most advanced technologies in the US next year, Minister of Economic Affairs J.W. Kuo (郭智輝) said yesterday. Kuo made the comment during an appearance at the legislature, hours after the chipmaker announced that it would invest an additional US$100 billion to expand its manufacturing operations in the US. Asked by Taiwan People’s Party Legislator-at-large Chang Chi-kai (張啟楷) if TSMC would allow its most advanced technologies, the yet-to-be-released 2-nanometer and 1.6-nanometer processes, to go to the US in the near term, Kuo denied it. TSMC recently opened its first US factory, which produces 4-nanometer
GREAT SUCCESS: Republican Senator Todd Young expressed surprise at Trump’s comments and said he expects the administration to keep the program running US lawmakers who helped secure billions of dollars in subsidies for domestic semiconductor manufacturing rejected US President Donald Trump’s call to revoke the 2022 CHIPS and Science Act, signaling that any repeal effort in the US Congress would fall short. US Senate Minority Leader Chuck Schumer, who negotiated the law, on Wednesday said that Trump’s demand would fail, while a top Republican proponent, US Senator Todd Young, expressed surprise at the president’s comments and said he expects the administration to keep the program running. The CHIPS Act is “essential for America leading the world in tech, leading the world in AI [artificial
REACTIONS: While most analysts were positive about TSMC’s investment, one said the US expansion could disrupt the company’s supply-demand balance Taiwan Semiconductor Manufacturing Co’s (TSMC, 台積電) new US$100 billion investment in the US would exert a positive effect on the chipmaker’s revenue in the medium term on the back of booming artificial intelligence (AI) chip demand from US chip designers, an International Data Corp (IDC) analyst said yesterday. “This is good for TSMC in terms of business expansion, as its major clients for advanced chips are US chip designers,” IDC senior semiconductor research manager Galen Zeng (曾冠瑋) said by telephone yesterday. “Besides, those US companies all consider supply chain resilience a business imperative,” Zeng said. That meant local supply would
Servers that might contain artificial intelligence (AI)-powering Nvidia Corp chips shipped from the US to Singapore ended up in Malaysia, but their actual final destination remains a mystery, Singaporean Minister for Home Affairs and Law K Shanmugam said yesterday. The US is cracking down on exports of advanced semiconductors to China, seeking to retain a competitive edge over the technology. However, Bloomberg News reported in late January that US officials were probing whether Chinese AI firm DeepSeek (深度求索) bought advanced Nvidia semiconductors through third parties in Singapore, skirting Washington’s restrictions. Shanmugam said the route of the chips emerged in the course of an
