32 Banned Chips Found in Chinese Telecom

32 Nvidia Blackwell Ultra B300 GPUs have been identified within the infrastructure of China Telecom, a state-owned telecommunications entity. These specific chips are currently barred from export to China under U.S. regulations, creating a significant anomaly in the global semiconductor supply chain. The discovery raises pressing questions about how hardware restricted to whitelisted buyers ended up in a Chinese data center, despite strict controls designed to prevent such transfers.

The presence of these components highlights a persistent loophole in enforcement mechanisms. In 2025, reports indicated that Chinese entities smuggled one billion dollars' worth of Nvidia AI chips into the country over a three-month period. While the B200 model was the primary target at that time, distributors were already positioning themselves for the B300 series. This pattern suggests that the flow of high-performance compute resources into China remains a structural challenge for U.S. export policy.

Nvidia has responded to the findings by characterizing the incident as minor in the broader context of global compute capacity. A spokesperson stated that recent court cases have shown diversion rates of less than half of one percent. The company argued that this volume is a "drop in the bucket" compared to the massive domestic compute infrastructure China already possesses. Nvidia maintains that with tens of millions of GPUs in service in approved nations, smuggling remains a non-factor that is effectively managed by governments on both sides.

The methodology behind the discovery offers a glimpse into potential security oversights. Israeli security firm Lava identified the chips using Nvidia's DCGM Exporter tool, a software utility intended for internal server health monitoring. Although designed for data center operators, this tool can sometimes be accessed from outside the network and may not always require password authentication. It remains unclear exactly where within China Telecom’s network the chips are located or how they were physically installed, though Nvidia has acknowledged it is developing a specific tool to locate its chips, which has not yet been released.

The demand for the B300 is driven by its substantial performance upgrades over the previous generation. Announced in March of last year, the chip offers 50% more memory and FP4 compute capability than the B200. Nvidia marketed it as built for the age of reasoning, specifically citing advanced large language models. The chip was originally expected to ship by the end of 2025, but its status as a hot commodity led to illicit activity. In August 2026, nine individuals in Taiwan were indicted for illegally exporting B300s, following an internal investigation at Supermicro that resulted in employee terminations. The smuggling route involved a whitelisted Taiwanese trading firm named Flying Tiget Tech.

The scarcity of modern silicon has also inflated the value of older hardware. Nvidia’s A100 servers, which are five years old, have seen prices triple and can now command up to $82,000. This price surge has led some operators to retool gaming GPUs for AI workloads as a stopgap measure. As the crackdown on smuggling continues, the tension between export controls and market demand appears to be intensifying, with both legal and illicit channels contributing to the complex landscape of global AI infrastructure.
