Taiwan Semiconductor Manufacturing Co. Ltd.TSMC is urged to scrutinize orders to prevent chips reaching sanctioned Chinese firms, increasing compliance burden and risk.
Republican Congressman John Moolenaar, who leads the House Select Committee on China, called on the Trump administration to enforce a rule requiring chip manufacturers to scrutinize orders of advanced chips from companies that could be fronting for untrusted Chinese firms. In a letter dated Thursday to Commerce Department official Jeffrey Kessler, Moolenaar described the measure as critical to preventing China from accessing high-end U.S. chips and preserving America's technological edge, warning that if factories like TSMC determine their chips are not subject to the rules, it would dramatically increase the risk of another export control failure like the one involving Sophgo and Huawei. The letter, not previously reported, signals growing congressional concern, even among Republicans, over the administration's more lenient approach to advanced chips reaching China. The Biden-era rule was unveiled in January 2025 after Sophgo had chips made at TSMC that were later found inside AI processors marketed by heavily sanctioned Huawei, but uncertainty over enforcement grew after the Trump administration said it would not enforce another related chip regulation.

Huawei is the target of the export control enforcement, potentially restricting its access to advanced chips.
Sophgo is cited as a past example of export control failure, and the letter aims to prevent similar issues.
