US Commerce Department clarifies AI chip export ban applies to Chinese-headquartered firms operating outside China

The Bureau of Industry and Security (BIS) issued guidance on June 1, 2026 confirming that existing licensing requirements for advanced AI chips, including Nvidia's Blackwell GPUs, apply to all subsidiaries and affiliates of China-headquartered companies regardless of where those entities are physically located. The clarification follows the Trump administration's May 2025 repeal of the Biden-era AI Diffusion Framework, a rollback that a former State Department official alleges created an exploitable loophole allowing Chinese firms to procure controlled chips at scale through offshore entities. BIS's own language implicitly acknowledges such shipments occurred by stating that companies that already acquired chips under the loophole are not required to cease using them. For financial institutions, this signals that the effective perimeter of US chip controls is being tightened operationally even as the formal regulatory architecture was loosened, sustaining ambiguity around the true addressable market for US AI semiconductor vendors in China-adjacent channels.
