Taiwan has taken its most concrete legal step yet in an investigation that’s been building for months, formally indicting nine people, including employees connected to Nvidia and Super Micro Computer, over the alleged illegal export of AI servers to China. Keelung District Prosecutors announced the indictments this week, accusing the group of illegally exporting high-end AI servers in violation of the export controls Washington has placed on Nvidia’s most advanced chips. It’s a significant marker in a case that started as a routine drug investigation and turned into one of the more consequential chip-smuggling probes to hit the global AI supply chain this year.
In their statement, prosecutors said the defendants were “fully aware” that both Nvidia and Super Micro maintain what they described as rigorous internal compliance procedures around exports, but that the group “colluded with one another at various levels for enormous profit,” illegally moving high-end servers out of Taiwan while damaging the country’s international standing and driving up compliance costs for legitimate businesses. Prosecutors did not release the defendants’ full names, following standard practice in Taiwan for cases still working through the legal system, but confirmed the group includes individuals employed by both companies.
The origin story behind this case is almost stranger than the crime itself. The investigation reportedly gained momentum after Taiwan’s Coast Guard, while probing an unrelated gang-related drug smuggling operation, kept noticing repeated references to something called “B300” in intercepted communications between suspects. Investigators initially assumed it was slang for a narcotic. It turned out to refer to one of Nvidia’s high-end AI chip designations, and that discovery redirected the entire investigation toward a completely different kind of contraband.
Once prosecutors pulled that thread, they found evidence pointing to a scheme in which individuals allegedly falsified export documentation for Super Micro servers built around Nvidia’s restricted chips, routing at least one shipment through Japan before it reportedly made its way toward China. Three individuals were detained early on by the Keelung District Prosecutors Office for allegedly forging paperwork tied to those exports, and investigators seized roughly 50 servers connected to the operation. By late June, the number of people under investigation had grown to nine, according to Huang Sheng, head of the Keelung Prosecutors’ Office, up from the three originally suspected, as raids expanded to include the Taiwan offices of Super Micro Computer and two additional tech firms.
The case escalated further in July when prosecutors detained an employee identified by Taiwan authorities as an insider at Nvidia. The individual, named as Zhang Denglong and described as a senior business manager at the company, is accused of forging documents to disguise the transshipment of AI servers destined for mainland China, Hong Kong and Macau. Reuters separately reported that the person detained was an Nvidia employee, and that investigators had searched the company’s Taipei office as part of the widening probe. A second round of searches also touched publicly listed AOpen Inc., with prosecutors questioning AOpen’s general manager along with several Super Micro sales staff.
There’s a direct link between what’s unfolding in Taiwan and a parallel case that’s already made its way through the U.S. justice system. In March 2026, the U.S. Attorney’s Office for the Southern District of New York charged Super Micro co-founder Liao Yixian, along with Taiwan sales manager Zhang Ruicang and a partner-company employee named Sun Tingwei, with export control violations and smuggling offenses. Liao and Sun have appeared before U.S. authorities, though Zhang’s whereabouts remain unknown, and because Taiwanese nationals were implicated in the American case, authorities in Taiwan opened their own investigation to run alongside it.
That U.S. indictment described a scheme in which the trio allegedly diverted roughly $2.5 billion worth of Supermicro servers containing restricted Nvidia GPUs, including banned H200 and B200 models, to China between 2024 and 2025 without the required Commerce Department licenses, using a Southeast Asian intermediary company to disguise the true destination of the hardware and repackaging shipments to strip identifying branding before forwarding them to Chinese buyers.
For Taiwan, this marks the island’s first public crackdown on AI chip diversion after years of pressure from Washington to take a more active enforcement role in curbing China’s access to restricted American technology. That distinction matters. Taiwan sits at the center of the global AI hardware supply chain, both as the home of TSMC, the world’s dominant advanced chip foundry, and as a base for major server assemblers like Super Micro’s local operations and AOpen. Any perception that Taiwanese firms or individuals are being used as a conduit for smuggling restricted chips into China carries real diplomatic and economic weight, particularly given how central Taiwan’s semiconductor industry is to U.S. and allied efforts to keep advanced AI compute out of Chinese hands.
Washington’s export controls on advanced AI chips date back to 2022 and have been tightened repeatedly since, targeting the specific class of high-performance GPUs that Nvidia builds for large-scale AI training and inference workloads. These restrictions have created a persistent gray market pressure point, since the underlying hardware remains extremely valuable to Chinese buyers who are otherwise cut off from purchasing it directly. That pressure has produced a steady stream of related cases well beyond Taiwan, including U.S. prosecutions of individuals accused of routing restricted Nvidia chips through Malaysia, Thailand and Singapore using shell companies and falsified paperwork, underscoring how widespread the smuggling routes around these controls have become.
Neither Nvidia nor Super Micro has been charged as a company in the Taiwan case, and both firms have previously stated they cooperate with export control enforcement and maintain internal compliance programs designed to prevent unauthorized diversion of their products. Nvidia has repeatedly noted in its own regulatory filings that expanding export restrictions represent a material risk to its business, given how central China-adjacent markets have historically been to demand for its data center hardware. Whether these new indictments lead to convictions, and how they might affect Taiwan’s broader relationship with both Washington and Beijing on tech enforcement, will likely take months to play out as the case moves through Taiwan’s court system. Techora will continue following developments in this case as prosecutors release further details.
