A Supermicro contractor has pled guilty to four counts tied to an alleged scheme that shipped roughly $2.5 billion in Nvidia GPU servers to China without a Commerce Department license. Ting-Wei “Willy” Sun entered the pleas on October 9 in a Manhattan federal court, seven months after his initial arrest.

The counts Sun admitted to include conspiracies to violate export controls, smuggle goods, defraud the US, and obstruct justice. His sentencing is scheduled for September 8, 2027.

Who is charged in the Supermicro smuggling case?

Sun was one of three Supermicro workers the US government charged with illegally moving Nvidia GPU servers into China. According to the indictment, Supermicro lacked the required export license for the shipments.

The accused also included Supermicro co-founder Yih-Shyan “Wally” Liaw, who resigned from the company's board of directors after his arrest. In early April, he pled not guilty to the charges in a Manhattan federal court.

How did the alleged scheme work?

Prosecutors describe a multi-step operation designed to disguise the origin and destination of the hardware:

• Defendants repackaged Supermicro servers into unmarked boxes to hide the contents.
• They built “dummy” replica servers to fool audits.
• Surveillance footage shows individuals using a hair dryer to transfer serial numbers from real servers onto the dummies.
• A Southeast Asia-based company served as a “pass-through entity” to move the chips from Taiwan to China via third parties.

The indictment states that the pass-through entity became one of Supermicro's largest customers in 2024, accounting for $99.7 million in revenue in the final quarter of that financial year.

What is Supermicro's position?

No charges have been brought against Supermicro itself. Earlier this year, the company declared it was “committed to protecting our advanced technologies and intellectual property,” and said it had been working “closely with the Taiwanese authorities” to prevent the “illicit diversion of our highly sought-after systems into the restricted China market.”

As a result of that collaboration, authorities seized 50 servers that had been “deceptively acquired after being sold by Supermicro to an authorized reseller,” the company said at the time.

What happened in Taiwan?

Reports emerged in June 2026 that Supermicro's Taiwanese office had been raided. The company responded with an open letter stating that authorities had confirmed Supermicro “is not the target of this investigation.” It also said its Taiwan offices were not raided by any government authorities, contrary to what was “widely misreported.”

The company did confirm a separate fact: four employees in Taiwan were detained for questioning over Supermicro's sale of products to an unnamed technology firm in the country. Supermicro said it cooperated with authorities by providing access to those workers' desks and electronic devices.

Two of the four employees remain detained pending a hearing. The other two have been released on bail.

What comes next?

Sun's guilty plea marks the first conviction-related development among the three charged individuals. Liaw's case remains open after his not-guilty plea in April. The September 2027 sentencing date sets a long runway before the court determines penalties for the four admitted conspiracy counts.
