# Nvidia B300 Chips Found at China Telecom

October 23, 2026 at 04:25 PM

> Israeli firm Lava discovers 32 restricted Nvidia Blackwell Ultra B300 chips in China Telecom's network despite strict U.S. export bans.

Israeli security firm **Lava** has identified 32 **Nvidia** **Blackwell Ultra B300** chips within the network of state-owned **China Telecom**. Using Nvidia's DCGM Exporter tool, which monitors server health, researchers located the hardware despite strict U.S. export bans.

The B300, announced in March 2025, features 50% more memory than the B200 and is restricted to whitelisted buyers. While Nvidia claims diversions are minimal, reports indicate Chinese firms smuggled $1 billion in AI chips during a three-month span in 2025.

This discovery follows the August 2026 indictment of nine individuals in **Taiwan** for illegal B300 exports. As Nvidia develops new tracking tools, the incident highlights ongoing challenges in preventing high-end GPU smuggling to sanctioned Chinese entities.
