Taiwan Semiconductor Manufacturing Co. (TSMC), the world’s leading contract chipmaker, has severed its relationship with PowerAIR, a Singapore-based company, following concerns over a potential breach of US export controls.

This action was taken after a TSMC chip was found in a Huawei Technologies AI processor, the South China Morning Post (SCMP) reported.
PowerAIR is the second known company implicated in the Huawei case. Last year, TSMC suspended shipments to the Chinese chip design firm Sophgo after discovering that a chip it supplied matched one used in Huawei’s Ascend 910B multi-chip system, according to a Reuters report in October 2024.
Since 2020, Huawei has been under a US-imposed blanket ban, cutting off its access to semiconductor foundries globally. TSMC has maintained that it has not supplied products to Huawei since the sanctions took effect.
In response, Huawei stated that it has not manufactured any chips using TSMC since the implementation of US restrictions.
Sophgo and its affiliate, Bitmain, a bitcoin mining equipment supplier, have denied business relationships with Huawei. TSMC has intensified its client screening procedures to prevent future breaches, tightening scrutiny after the discovery of its chip in Huawei's processor.
