US launches trade investigation into Chinese semiconductors amidst escalating tensions
US examines legacy chip imports from China.

The Biden administration has initiated a trade investigation targeting Chinese-made legacy semiconductors, which power everyday goods like cars and telecom equipment. This ‘Section 301’ probe aims to address concerns about China’s state-driven expansion in chip manufacturing, which US officials warn could harm American semiconductor producers. Departing President Joe Biden had already imposed a 50% tariff on Chinese semiconductors, set to take effect 1 January, while tightening export controls on advanced AI and memory chips.
Commerce Secretary Gina Raimondo revealed that Chinese legacy chips account for two-thirds of semiconductors in US products, with many companies unaware of their origin—a finding she called alarming, particularly for the defence industry. US Trade Representative Katherine Tai stated that China’s subsidised chip pricing threatens global competition, enabling rapid capacity growth and undercutting market-oriented producers.
China’s commerce ministry has criticised the probe, calling it protectionist and a potential disruptor to global supply chains. Meanwhile, a public hearing on the issue is scheduled for March, with the probe expected to conclude within a year. The investigation follows the COVID-19 pandemic’s impact on semiconductor supply chains, prompting the US efforts to bolster domestic chip production with $52.7 billion in subsidies.
As the Biden administration transitions to President-elect Donald Trump’s leadership in January, this probe may offer Trump an opportunity to escalate tariffs on Chinese imports, echoing the trade practices he implemented during his prior term. Critics, including the US tech industry, have urged officials to approach the investigation collaboratively to avoid further disruption.
