China reopens Nvidia probe

Chinese authorities have reopened scrutiny of Nvidia-linked server sales after invoice records pointed to systems built for high-end artificial intelligence chips restricted by the United States. (cloudnews.tech) The records reviewed in China described 276 Super Micro SYS-821GE-TNHR servers and 32 Dell PowerEdge XE9680 servers sold in May and June 2025 to a Shenzhen subsidiary for 632 million yuan, about $92 million. Bloomberg reported the filings came from Shenzhen-based Sharetronic Data Technology, whose shares fell by the daily 20% limit after the disclosures drew attention. (bloomberg.com) The server models matter because Super Micro’s product page says the SYS-821GE-TNHR supports Nvidia HGX H100 and H200 eight-graphics-processor configurations, and Dell’s technical guide lists H100, H200 and H20 options for the XE9680. The invoices do not by themselves prove which chips were installed, but they tie the sales to machines designed for the exact accelerators at the center of export controls. (supermicro.com) (delltechnologies.com) Those controls come from U.S. Commerce Department rules issued on October 7, 2022 and tightened again on October 17, 2023, which restricted advanced computing exports to China. In plain terms, Washington stopped treating only the chip as the controlled item and started policing the computing power that a finished system could deliver. (bis.gov) (cset.georgetown.edu) That is why the reopened Chinese review reaches past Nvidia itself and into the companies that assemble, distribute and resell full server racks. A server is the box that holds processors, memory and networking gear, and for artificial intelligence buyers it is often the practical unit of trade, not the chip sold on its own. (cloudnews.tech) (delltechnologies.com) The timing also overlaps with a new U.S. criminal case. On March 19, 2026, the Justice Department unsealed charges against Super Micro co-founder Yih-Shyan “Wally” Liaw and two others, alleging they conspired to divert U.S.-assembled artificial intelligence servers to China through Taiwan and Southeast Asia in violation of export-control laws. (justice.gov) Sharetronic told Bloomberg it complies with regulations for hardware purchases and has “no business cooperation or relationship” with Super Micro. Super Micro said it had started an independent internal investigation after the U.S. indictment, while Dell said it had no transaction record involving Sharetronic. (bloomberg.com) (cloudnews.tech) The reopened case shows how the trade fight has shifted from single chips to paperwork, model numbers and compatibility lists. In this phase, an invoice for a server that can host an H100 or H200 can draw as much scrutiny as the chip itself. (cloudnews.tech) (supermicro.com)
