# Security firm finds 32 export-barred Nvidia B300 GPUs in China Telecom network

*2026-10-23 · Source: [Tom's Hardware](https://www.tomshardware.com/tech-industry/data-centers/illegal-nvidia-blackwell-ultra-b300-gpus-found-inside-state-owned-china-telecoms-network-nvidia-says-chip-smuggling-a-drop-in-the-bucket-insists-smuggling-remains-a-nonfactor)*

A security firm identified 32 Nvidia Blackwell Ultra B300 chips running inside a China Telecom network. It is unclear where the export-restricted hardware is physically located.

**Why it matters:** It is concrete evidence that US export controls on top-end accelerators are leaking, even into a state-owned carrier. That raises the odds of tighter enforcement on resellers and cloud access, which sits alongside China's reported $35B order for export-compliant RTX Pro 5500 chips and the US ban on DeepSeek in federal agencies.

**Topics:** chips, policy
