Restricted Nvidia Chips Found in State-Run Chinese Network

The ongoing tension between U.S. export controls and the rapid expansion of Chinese artificial intelligence infrastructure has produced a new point of contention in the global tech landscape. An Israeli security firm named Lava has announced that it has identified 32 units of the Nvidia Blackwell Ultra B300 GPU within the internal network of China Telecom. This state-owned telecommunications provider serves a vast domestic market, making the discovery of restricted hardware a significant event for observers of the semiconductor trade.

The presence of these specific chips is noteworthy because they are subject to strict U.S. export controls that generally bar their sale to sanctioned parties, including entities in China. According to a report by The Information, these high-performance AI data center chips are only permitted for sale to buyers on a specific whitelist who agree not to divert the hardware to restricted destinations. The discovery by Lava raises immediate questions about the integrity of the current export control mechanisms and how such advanced silicon managed to bypass these regulatory barriers to reach a major Chinese data center.

This incident is not an isolated case of hardware moving against the grain of trade policy. In 2025, reports indicated that Chinese entities had smuggled approximately $1 billion worth of Nvidia AI chips into the country in a span of just three months. At that time, the B200 chips were the primary target of illicit trade, but distributors were already positioning themselves to acquire the newer B300 series as soon as it became available. The current finding underscores that the proliferation of export-controlled chips into China remains a persistent challenge for policymakers and manufacturers alike.

Nvidia has responded to the news with a measured tone, choosing to downplay the significance of the finding without outright denying the facts. A spokesperson for the company told Tom's Hardware that governments, researchers, and media outlets have previously identified only insignificant diversion of controlled U.S. products. The spokesperson noted that recent court cases have shown diversion rates of less than half of one percent, describing this figure as a drop in the bucket compared to the massive amount of domestic compute power China already possesses. The company emphasized that with tens of millions of GPUs in service in approved countries, smuggling remains a non-factor that is effectively blocked by governments on both sides of the globe.

Despite Nvidia's perspective, the exact mechanism by which the B300 chips entered China Telecom's server racks remains unknown. Lava has also not been able to confirm the precise location of the hardware within the company's broader network. However, the firm stated that the chips are definitely present and were identified using Nvidia's own DCGM Exporter tool. This software is typically installed by data center operators to monitor server health and performance. While designed for internal use, the tool can often be accessed from outside the data center's network and does not always require password authentication, a vulnerability that may have facilitated the discovery.

The desire for these specific chips is driven by their considerable technical specifications. Announced in March of last year, the Blackwell Ultra B300 is one of the most powerful data center GPUs available. It offers substantial performance improvements over the previous-generation B200, including 50% more memory and increased FP4 compute capabilities. Nvidia originally marketed the chip as being built for the age of reasoning, highlighting its suitability for sophisticated large language models such as DeepSeek R1. The B300 was expected to ship by the end of 2025, and it quickly became a highly sought-after asset in the AI sector.

The illicit trade of these chips has led to legal consequences for those involved in the supply chain. In August 2026, nine individuals in Taiwan were indicted for the illegal export of B300 GPUs to China. This legal action occurred shortly after Supermicro confirmed that it had dismissed several employees following an internal investigation into smuggling activities. The complex smuggling operations reportedly involved a Taiwanese server trading firm called Flying Tiget Tech, which held whitelisted status for GPU purchases, allowing it to navigate the regulatory landscape more easily than non-whitelisted buyers.

The high demand for Nvidia's latest silicon has also impacted the secondary market for older hardware. A100 servers, which are five years old, have seen their prices triple, with some units costing up to $82,000. This price surge reflects the critical importance of these chips to AI data centers. The ongoing crackdown on smuggling has even led some operators to retool gaming GPUs to handle AI workloads where possible, illustrating the extent to which the industry is willing to adapt to hardware shortages.

Nvidia is aware of the need for better tracking capabilities and has previously confirmed it is developing a tool to locate its chips more effectively. However, this tool has yet to be released. Until such measures are implemented, the gap between regulatory intent and market reality will likely continue to present challenges for both the chipmaker and the governments relying on export controls to manage the flow of advanced technology.
