Smuggled Nvidia B300 Chips Discovered in China Telecom’s State-Owned Network

A significant breach in U.S. export controls has been uncovered after Israeli security firm Lava identified 32 Nvidia Blackwell Ultra B300 GPUs operating within the network of China Telecom. The discovery is notable because the state-owned telecommunications provider is in a country where these specific high-performance chips are barred from export. The presence of the hardware raises immediate questions about how restricted silicon managed to bypass strict whitelisting protocols that prevent sales to sanctioned parties.

This incident highlights a persistent challenge in regulating the flow of advanced AI hardware. In 2025, reports indicated that Chinese entities smuggled approximately $1 billion worth of Nvidia AI chips into the country over a three-month period. While the B200 series was the primary target at that time, distributors were already positioning themselves to move the newer B300 series as soon as it became available. The current finding confirms that the proliferation of controlled chips into China remains a logistical reality for global markets.

Nvidia has responded to the report by downplaying the impact of the breach, though the company did not dispute Lava’s findings. In a statement, a company spokesperson described the diversion of controlled U.S. products as less than half of one percent in recent court cases. The spokesperson characterized the smuggling as a 'drop in the bucket' compared to the vast amount of domestic compute capacity China already possesses, asserting that the issue is a non-factor given the tens of millions of GPUs in service in approved countries.

The mechanism behind the discovery involves Nvidia’s own DCGM Exporter tool, a software utility used by data center operators to monitor server health and performance. Although designed for internal use, the tool can sometimes be accessed from outside the data center’s network and does not always require password authentication. Lava used this software to pinpoint the specific chips within China Telecom’s infrastructure, although the exact physical location within the company’s network remains unconfirmed. Nvidia has previously acknowledged work on a new tool to help locate its chips, but that solution has yet to be released.

The Blackwell Ultra B300, announced in March 2025, is a critical asset for AI development, offering 50% more memory and FP4 compute capabilities than its predecessor, the B200. Nvidia originally marketed the chip as being 'built for the age of reasoning,' specifically citing advanced large language models like DeepSeek R1. The chip was expected to ship by the end of 2025, and it quickly became a target for illicit trade. In August 2026, nine individuals in Taiwan were indicted for the illegal export of B300 GPUs, a move that followed Supermicro firing several employees after an internal investigation into smuggling activities involving a whitelisted trading firm.

The scarcity of these advanced chips has driven up prices for older hardware, with Nvidia’s A100 servers tripling in value to as much as $82,000 despite being five years old. The intense demand has also led some operators to retool gaming GPUs for AI workloads. As the crackdown on smuggling continues, the discovery within China Telecom serves as a reminder that export controls, while strict, face constant pressure from the high-stakes race for AI computational power.

The next steps involve continued monitoring of the affected network and potential further investigations into the supply chain. Nvidia remains confident that the overall volume of smuggled hardware is negligible compared to the total market size, but the incident underscores the ongoing tension between U.S. regulatory goals and the global appetite for cutting-edge AI infrastructure.
