What Happened

Ting-Wei “Willy” Sun, a Taiwan-based contractor linked to Super Micro Computer, pleaded guilty to conspiring to ship servers containing restricted Nvidia AI chips to China, Reuters reported Friday. Sun entered the plea Thursday in U.S. District Court in Manhattan, and a court filing made it public Friday.

He admitted four conspiracy counts: violating U.S. export controls, smuggling goods out of the U.S., defrauding the U.S. and obstructing justice. The Justice Department's March announcement listed three conspiracy charges and did not include obstruction.

The indictment describes Sun as a broker and “fixer.” It accuses him of helping stage dummy servers in December 2025 and of lying to a Commerce Department officer who was inspecting servers that were supposedly in storage but had already been sent to China. Nvidia's B200, H100 and H200 GPUs, and servers containing them, are restricted from sale to China.

Reuters did not report a sentencing date or whether Sun agreed to cooperate. Sun's lawyer declined to comment to Reuters.

The Wider Case

The Justice Department announced the charges on March 19. Besides Sun, 44, it charged Yih-Shyan “Wally” Liaw, 71, of Fremont, California, a co-founder and board member of the server maker, and Ruei-Tsang “Steven” Chang, 53, then the company's general manager in Taiwan, whom the department described as a fugitive. The department's announcement did not name the server maker, which has been identified elsewhere as Super Micro.

Liaw has pleaded not guilty, according to Tom's Hardware. Liaw's lawyer did not respond to Reuters, and Chang's lawyer could not be reached. All defendants are presumed innocent unless proven guilty.

Prosecutors allege that a Southeast Asian company bought about $2.5 billion in servers from the manufacturer in 2024 and 2025, and that the machines were repackaged in unmarked boxes and sent to China under false paperwork naming the buyer as the end user. About $510 million worth went out in roughly three weeks, from late April to mid-May 2025, according to the department. Prosecutors also allege that thousands of nonworking replicas were staged in a warehouse to deceive the manufacturer's compliance team and a Commerce Department inspection.

U.S. Attorney Jay Clayton of the Southern District of New York said in March that the defendants worked through “a tangled web of lies, obfuscation, and concealment.” The export-control conspiracy carries a maximum of 20 years in prison, and the smuggling and fraud conspiracies carry five years each.

Super Micro is not a defendant. It pointed Reuters to earlier statements that the matter has had no impact on its business operations, and it terminated Sun and cut ties with the other defendants earlier this year.

Why It Matters

Export compliance often relies on paper end-user declarations and physical inventory checks, and the alleged scheme defeated both. The case also raises governance questions about who can steer large orders inside a major U.S. server maker. It is one of several 2026 prosecutions over AI server diversion, including a California case involving more than $300 million in servers that The Primary Wire covered Oct. 1.

What to Watch

Key markers include a sentencing date for Sun and any filing showing whether he will testify, proceedings against Liaw and Chang, and whether the Commerce Department's Bureau of Industry and Security, which investigated with the FBI, tightens inspection or end-use verification rules for AI servers.
