China discloses banned Nvidia server imports

A Shenzhen company called Sharetronic told Chinese regulators it had bought about $92 million of servers carrying Nvidia H100 and H200 chips, the same high-end processors the United States has tightly restricted for sales to China. The disclosure surfaced in a filing on April 10, 2026, and the company’s shares fell by the daily 20% limit after the news spread. (bloomberg.com) Those are not ordinary server parts. Nvidia says the H100 is built for giant artificial intelligence training jobs, and the newer H200 carries 141 gigabytes of high-bandwidth memory, nearly double the H100’s capacity, so one rack can do far more work on large language models. (nvidia.com, nvidia.com) The United States started closing this door in October 2023, when the Bureau of Industry and Security expanded export controls on advanced computing chips and the machines that use them. The rule was aimed at keeping top-end artificial intelligence and supercomputing hardware out of China without a license. (bis.gov, cset.georgetown.edu) That is why this filing landed so hard. A company in China did not just hint that restricted chips were circulating in the grey market; it effectively put a dollar figure and product trail into a government disclosure. (bloomberg.com) The timing made it worse. U.S. prosecutors said on March 19, 2026 that three people tied to server maker Super Micro were charged with conspiring to divert cutting-edge U.S. artificial intelligence servers to customers in China, and prosecutors described the scheme as involving massive quantities of servers. (justice.gov, nbcnews.com) Bloomberg reported that Sharetronic said it had no business relationship with Super Micro and complied with hardware rules, but invoices reviewed by Bloomberg showed Super Micro systems containing Nvidia H100 or H200 processors. That leaves buyers, resellers, and financiers arguing over a basic question that used to be simpler: where exactly did each machine come from, and was every transfer legal. (bloomberg.com) This is not a one-off leak. Reuters reported in July 2025 that Nvidia chips worth at least $1 billion were smuggled into China in just three months after Washington tightened controls, with the banned B200, H100, and H200 all showing up in Chinese markets. (reuters.com, finance.yahoo.com) Nvidia has been warning that unauthorized gear creates its own trap. Reuters reported the company said building data centers with smuggled products is inefficient because Nvidia only provides service and support for authorized products, which turns provenance into something closer to a warranty card than a customs form. (reuters.com) So the fight is shifting from “can China still get the chips” to “can anyone prove a server is clean.” A machine with a banned processor can still run, but if the paperwork is shaky, the owner can face regulatory risk, support risk, resale risk, and financing risk all at once. (bloomberg.com, reuters.com) That is why one Shenzhen filing matters beyond one Shenzhen company. It turned a rumor-filled shadow market into a paper trail with names, invoices, chip models, and a price tag, and paper trails are what regulators, prosecutors, insurers, and lenders know how to act on.
