China Telecom Found Housing 32 Restricted Nvidia B300 Chips

For consumers and industry observers tracking the global semiconductor supply chain, the discovery of thirty-two Nvidia Blackwell Ultra B300 processors within the infrastructure of China Telecom signals a persistent gap in international export controls. These chips, which are subject to strict U.S. regulations, have been confirmed present in the network of the state-owned telecommunications provider, raising fresh questions about the efficacy of current enforcement mechanisms in the region.

The identification of the hardware was conducted by Lava, an Israeli security firm, which utilized Nvidia’s own DCGM Exporter tool to locate the units. This software is typically 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's network and does not consistently require password authentication. Although Lava confirmed the presence of the chips, the exact location within China Telecom’s network remains unknown.

The presence of these specific processors is notable because the B300 series has been barred from export to China under U.S. regulations. Such high-performance GPUs are generally restricted to whitelisted buyers who agree not to sell the hardware to sanctioned parties. The discovery adds to a growing list of incidents where export restrictions have been bypassed, following reports in 2025 that approximately $1 billion worth of Nvidia AI chips were smuggled into China over a three-month period.

Nvidia has responded to the findings with a measured tone, neither fully denying the report nor overstating its impact. A spokesperson for the company stated that recent court cases have shown the diversion of controlled U.S. products to be less than one-half of one percent of the total volume. The spokesperson described this figure as a drop in the bucket compared to the vast amount of domestic compute capacity China already possesses, asserting that smuggling remains a non-factor given the tens of millions of GPUs currently in service in approved countries.

The B300 chip, announced in March 2025, represents a significant leap in performance over its predecessor, the B200. It offers 50 percent more memory and FP4 compute capability, features that Nvidia highlighted as essential for advanced AI reasoning models. The chip was expected to ship by the end of 2025 and quickly became a highly sought-after commodity in the global market.

The difficulty in tracing the B300 chips is compounded by the complex logistics of smuggling. In August 2026, nine individuals in Taiwan were indicted for the illegal export of these GPUs to China. This legal action followed an investigation by Supermicro, which resulted in the dismissal of several employees. The smuggling operation allegedly involved a Taiwanese server trading firm with whitelisted status, illustrating the intricate pathways through which controlled hardware can move.

The high demand for Nvidia’s silicon has had a broader impact on the market, driving up prices for older hardware. A100 servers, which are now five years old, have seen their prices triple, with some units commanding up to $82,000. In some cases, operators have resorted to retooling gaming GPUs to handle AI workloads, highlighting the intense competition for available compute resources.

While the discovery of thirty-two chips in a single major network may appear modest, it underscores the ongoing challenges in monitoring the flow of advanced technology. The incident also highlights the utility of Nvidia’s monitoring tools, even as the company works on a more comprehensive solution to locate its hardware globally. For now, the B300 chips remain in service within China Telecom’s racks, a testament to the continued drive to secure powerful AI infrastructure.
