Chinese companies are buying US chipmaking equipment to make advanced semiconductors, despite a raft of new export curbs aimed at thwarting advances in the country’s semiconductor industry, a report said on Tuesday.
The 741-page annual report, released by the US-China Economic and Security Review Commission, takes aim at the export curbs imposed in October last year by the administration of US President Joe Biden, which seek to bar Chinese chipmakers from getting US chipmaking tools if they would be used to manufacture advanced chips at the 14-nanometer node or below.
With the US Department of Commerce using the 14-nanometer restriction limit, “importers are often able to purchase the equipment if they claim it is being used on an older production line, and with limited capacity for end-use inspections, it is difficult to verify the equipment is not being used to produce more advanced chips,” the report said.

The finding comes as the US scrambles to figure out how Chinese telecoms giant Huawei Technologies Co (華為) produced an advanced 7-nanometer chip to power its Mate 60 Pro smartphone at China’s top chipmaker, Semiconductor Manufacturing International Corp (SMIC, 中芯), despite the export curbs announced last year.
Huawei and SMIC were also added to a trade restriction list in 2019 and 2020, which in theory bars US suppliers from shipping some technology to the companies.
China watchers had theorized that SMIC could have made the chip with equipment obtained prior to last year’s rules, but it had other options for obtaining the equipment from overseas, the report said.
The US plugged a key loophole in its efforts to stymie China’s access to advanced chipmaking tools by convincing allies Japan and the Netherlands, with similarly robust chipmaking equipment industries, to announce their own restrictions on exports of the technology.
However, China stockpiled equipment by taking advantage of the lag between the US’ rules, and Japan and the Netherlands’ similar moves in July and September respectively, the report said.
In the first eight months of this year, China imported US$3.2 billion of semiconductor manufacturing machines from the Netherlands, a 96.1 percent increase over the US$1.7 billion in the same period last year, the report said.
China’s imports of semiconductor equipment from all countries totaled US$13.8 billion in the period, it said.
The report does not outline a specific recommendation to address the gaps in the US rules, but urges the US Congress to request an annual evaluation, to be completed within six months by the US General Accountability Office and later made public, of the effectiveness of export controls on chipmaking equipment to China.
Nvidia Corp’s demand for advanced packaging from Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) remains strong though the kind of technology it needs is changing, Nvidia CEO Jensen Huang (黃仁勳) said yesterday, after he was asked whether the company was cutting orders. Nvidia’s most advanced artificial intelligence (AI) chip, Blackwell, consists of multiple chips glued together using a complex chip-on-wafer-on-substrate (CoWoS) advanced packaging technology offered by TSMC, Nvidia’s main contract chipmaker. “As we move into Blackwell, we will use largely CoWoS-L. Of course, we’re still manufacturing Hopper, and Hopper will use CowoS-S. We will also transition the CoWoS-S capacity to CoWos-L,” Huang said
Nvidia Corp CEO Jensen Huang (黃仁勳) is expected to miss the inauguration of US president-elect Donald Trump on Monday, bucking a trend among high-profile US technology leaders. Huang is visiting East Asia this week, as he typically does around the time of the Lunar New Year, a person familiar with the situation said. He has never previously attended a US presidential inauguration, said the person, who asked not to be identified, because the plans have not been announced. That makes Nvidia an exception among the most valuable technology companies, most of which are sending cofounders or CEOs to the event. That includes
TARIFF TRADE-OFF: Machinery exports to China dropped after Beijing ended its tariff reductions in June, while potential new tariffs fueled ‘front-loaded’ orders to the US The nation’s machinery exports to the US amounted to US$7.19 billion last year, surpassing the US$6.86 billion to China to become the largest export destination for the local machinery industry, the Taiwan Association of Machinery Industry (TAMI, 台灣機械公會) said in a report on Jan. 10. It came as some manufacturers brought forward or “front-loaded” US-bound shipments as required by customers ahead of potential tariffs imposed by the new US administration, the association said. During his campaign, US president-elect Donald Trump threatened tariffs of as high as 60 percent on Chinese goods and 10 percent to 20 percent on imports from other countries.
INDUSTRY LEADER: TSMC aims to continue outperforming the industry’s growth and makes 2025 another strong growth year, chairman and CEO C.C. Wei says Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), a major chip supplier to Nvidia Corp and Apple Inc, yesterday said it aims to grow revenue by about 25 percent this year, driven by robust demand for artificial intelligence (AI) chips. That means TSMC would continue to outpace the foundry industry’s 10 percent annual growth this year based on the chipmaker’s estimate. The chipmaker expects revenue from AI-related chips to double this year, extending a three-fold increase last year. The growth would quicken over the next five years at a compound annual growth rate of 45 percent, fueled by strong demand for the high-performance computing
