US closes loophole that allowed Chinese-owned subsidiaries located outside China to buy AI chips

The U.S. Bureau of Industry and Security (BIS) recently issued new guidance to close a loophole that previously allowed Chinese-owned subsidiaries located outside China to purchase advanced AI chips. ... Read original →

The U.S. BIS move to close the overseas subsidiary loophole abruptly severs Chinese AI firms’ access to NVIDIA GB200 and AMD MI350x chips, forcing reliance on domestically produced alternatives lagging by at least two generations—crippling large-model training efficiency. This indirectly dampens demand for TSMC’s 3nm/EUV capacity from Chinese-linked entities. Compliance burdens will surge: chipmakers must overhaul KYC protocols, while TSMC faces heightened scrutiny on customer end-use, likely extending supply lead times by over 30%. Strategically, NVIDIA may fast-track 'compliance-optimized' SKUs to retain market share, while domestic players like Huawei Ascend gain temporary tailwinds but lack high-end scalability. Over the next 12–24 months, expect accelerated Chinese investment in sovereign AI silicon stacks and tighter global oversight of shell entities in Southeast Asia—further politicizing semiconductor supply chains.
