NEW YORK/SINGAPORE (Reuters) – The U.S. ordered Taiwan Semiconductor Manufacturing Co to halt shipments of superior chips to Chinese language clients which are typically utilized in synthetic intelligence functions beginning Monday (NASDAQ:), in keeping with an individual conversant in the matter.
The Division of Commerce despatched a letter to TSMC imposing export restrictions on sure refined chips, of seven nanometer or extra superior designs, destined for China that energy AI accelerator and graphics processing items (GPU), the particular person mentioned.
The U.S. order, which is being reported for the primary time, comes simply weeks after TSMC notified the Commerce Division that one in every of its chips had been present in a Huawei AI processor, as Reuters reported final month. Tech analysis agency Tech Insights had taken aside the product, revealing the TSMC chip and obvious violation of export controls.
Huawei, on the middle of the U.S. motion, is on a restricted commerce checklist, which requires suppliers to acquire licenses to ship any items or expertise to the corporate. Any license that would assist Huawei’s AI efforts would doubtless be denied.
TSMC suspended shipments to China-based chip designer Sophgo after its chip matched the one discovered on the Huawei AI processor, sources advised Reuters final month.
Reuters couldn’t decide how the chip ended up on Huawei’s Ascend 910B, launched in 2022, seen as probably the most superior AI chip out there from a Chinese language firm.
The newest clampdown hits many extra firms and can enable the U.S. to evaluate whether or not different firms are diverting chips to Huawei for its AI processor.

Ijiwei, a Chinese language media web site masking the semiconductor trade, reported on Friday that TSMC notified Chinese language chip design firms it could droop 7 nanometer or beneath chips for AI and GPU clients starting Nov. 11.
The motion comes as each Republican and Democratic lawmakers have raised considerations in regards to the inadequacy of export controls on China and the Commerce Division’s enforcement of them.
In 2022, the Commerce Division despatched is-informed letters to Nvidia (NASDAQ:) and AMD (NASDAQ:) limiting their capability to export prime AI-related chips to China, and to chip gear makers like Lam Analysis (NASDAQ:), Utilized Supplies (NASDAQ:) and KLA to limit instruments to make superior chips to China.
The restrictions in these letters have been later changed into guidelines that apply to firms past them.
The U.S. has been delayed in updating guidelines on tech exports to China.
