Smuggled Nvidia Blackwell Ultra B300 Chips Surface in Chinese Telecom Network

For consumers and businesses relying on stable supply chains, the discovery of restricted hardware in a major state-owned network highlights the ongoing friction in the global chip market. Israeli security firm Lava has identified 32 Nvidia Blackwell Ultra B300 graphics processing units within the network of China Telecom. This state-owned telecommunications provider operates across the country, making the presence of these specific chips a significant find given recent trade restrictions.

The B300 chips are currently barred from export to China under U.S. controls. According to a report from The Information, these high-performance units are generally only available to whitelisted buyers who agree not to sell them to sanctioned parties. The appearance of these processors in a Chinese data center raises questions about how the hardware bypassed these strict export rules and ended up in the hands of a major domestic player.

This incident is part of a broader pattern of movement in the chip market. In 2025, reports indicated that Chinese companies smuggled one billion dollars worth of Nvidia AI chips into the country over a three-month period. At that time, the B200 was the most sought-after model, but distributors were already preparing for the arrival of the newer B300 series. The latest findings from Lava confirm that the flow of controlled technology into China remains a persistent challenge for regulators and manufacturers alike.

Nvidia has responded to the news with a measured tone, choosing to downplay the significance of the leak without denying the facts. A spokesperson for the chipmaker told Tom's Hardware that the diversion of controlled products has been found to be less than half of one percent in recent court cases. The company described this amount as a drop in the bucket when compared to the massive amount of domestic computing power China already possesses. With tens of millions of GPUs in service in approved countries, Nvidia maintains that smuggling remains a non-factor that is effectively blocked by governments on both sides of the Pacific.

The exact method used to move the B300 chips into China Telecom's server racks remains unknown. Lava also could not confirm the precise location of the chips within the company's wider network. However, the firm was able to identify the hardware using Nvidia's own DCGM Exporter tool. This software is installed by data center operators to monitor server health and performance. While designed for internal use, the tool can sometimes be accessed from outside the data center network and does not always require password authentication. Nvidia has previously confirmed it is developing a tool to help locate its chips, but that solution has not yet been released.

The B300 is a highly desirable component for AI data centers. Announced in March of last year, the chip offers substantial performance improvements, including 50% more memory and FP4 compute capability than the previous-generation B200. Nvidia marketed the B300 as being built for the age of reasoning, citing advanced language models like DeepSeek R1. The chip was expected to ship by the end of 2025 and quickly became a hot commodity in the market.

The high value of these chips has led to complex smuggling operations. In August 2026, nine individuals in Taiwan were indicted for the illegal export of B300 GPUs to China. This action followed an investigation by Supermicro, which fired several employees after finding evidence of smuggling. The scheme involved a Taiwanese server trading firm known as Flying Tiget Tech, which held the necessary whitelisted status for GPU purchases. This case illustrates the intricate routes that can be used to move restricted hardware.

The scarcity of top-tier chips has also impacted the price of older models. Nvidia's A100 servers, which are five years old, have seen prices triple and can now cost up to $82,000. This surge in demand has even led some operators to retool gaming GPUs to handle AI workloads. As the crackdown on smuggling continues, the market remains in a state of flux, with companies and consumers adapting to the high costs and limited availability of the latest technology.

Looking ahead, the situation remains fluid. While Nvidia insists the impact of smuggling is minimal, the continued discovery of restricted chips in unexpected locations suggests the enforcement challenge is far from over. The release of Nvidia's new chip-location tool may help in the future, but for now, the market is watching closely to see if these leaks will influence future export policies or pricing strategies.
