How the US, Taiwan, and Singapore are cracking down on Nvidia AI chip smuggling to China

Authorities in three jurisdictions are simultaneously pursuing a widening crackdown on the alleged smuggling of Nvidia AI chips into China. In the span of a few days — between late June and early July 2026 — Taiwanese prosecutors raided Super Micro's offices and expanded their probe to nine suspects, Singapore seized a S$55 million luxury bungalow, and the US Commerce Department closed a critical loophole that had let Chinese firms buy restricted chips through foreign subsidiaries.

Here is a breakdown of the latest actions and what they mean for the enforcement of AI-chip export controls across Asia.

Taiwan detains Super Micro employees and expands smuggling probe

Taiwanese prosecutors investigating the alleged illegal export of advanced AI servers to China detained two Super Micro Computer employees in Taiwan, the company confirmed on July 2, 2026. Two other Taiwan-based staff were released on bail .

This follows a coordinated raid on June 29, 2026, in which Taiwanese authorities searched Super Micro's offices and 12 other sites — including the residences of six individuals and three affiliated companies such as Albatron Technology and Chief Telecom . The number of people under investigation in Taiwan has grown from the original three to nine as the probe deepens .

The investigation first became public in May 2026, when Taiwan sought to detain three individuals accused of forging documents to export Nvidia AI servers built by Super Micro to China — the island's first-ever public crackdown on semiconductor smuggling . Prosecutors suspect that at least one shipment was successfully smuggled to China via Japan .

Singapore seizes S$55 million mansion and charges four individuals

On July 1–2, 2026, Singapore authorities seized a luxury "Good Class Bungalow" valued at S$55 million (approximately $42.5 million) in a probe linked to Nvidia AI chip smuggling . A prohibition of disposal order has been placed on the property .

Police additionally seized about S$1 million ($770,000) from bank accounts and charged four individuals — Wei, Lim, Woon, and Li — with additional fraud and money laundering offences . The suspects are key officers of three Aperia Group companies and Luxuriate Your Life .

Four companies were also charged with making false representations. Preliminary investigations indicate that servers from Dell and Super Micro, possibly containing Nvidia AI chips, were sent to Singapore-based companies involved in the scheme . The total value of assets seized across the probe now exceeds S$56 million .

These developments build on a probe that began in late February 2025, when Singapore first charged three men with fraud in a case linked to the movement of Nvidia chips to Chinese AI firm DeepSeek .

US closes the "subsidiary loophole" on May 31, 2026

On May 31, 2026, the U.S. Commerce Department's Bureau of Industry and Security issued guidance that closed a year-old loophole: any company whose ultimate parent is headquartered in China or Macau now requires an export license to receive advanced Nvidia AI chips — regardless of where the purchasing subsidiary is registered .

This rule directly targets Chinese firms that had been routing chip purchases through subsidiaries in Malaysia, Singapore, and the UAE to bypass export controls . Estimates suggest that hundreds of thousands of restricted chips may have been sent to Chinese subsidiaries before the guidance was issued . The guidance is not retroactive; chips already installed in data centers may continue operating .

The US indictment of Super Micro's co-founder

In March 2026, the U.S. Justice Department indicted Super Micro co-founder Yih-Shyan "Wally" Liaw and two other individuals for allegedly diverting at least $2.5 billion worth of Nvidia-powered AI servers to China — the highest-profile U.S. criminal case on AI chip smuggling to date . The indictment charges that Liaw and co-conspirators sold the hardware to an unnamed Southeast Asian company that then repackaged and shipped it to customers in China . Super Micro itself is not named as a defendant and has stated it is cooperating with investigators .

Policy contradiction: US approves H200 exports while enforcement tightens

Adding complexity to the picture, in January 2026, the Trump administration officially approved the export of Nvidia's H200 AI chips to China, reversing a "presumption of denial" policy and allowing case-by-case review . However, China has since banned the import of those same chips , and Nvidia has stated that it has not yet recognized any revenue from approved H200 shipments to China . The situation remains contradictory: the US is simultaneously approving some chip exports, tightening loophole enforcement, and prosecuting alleged smugglers.

Key implications

Multi-jurisdictional coordination is accelerating. The March U.S. indictment, Taiwan's June raids, and Singapore's July asset seizures represent simultaneous actions in three jurisdictions targeting the same alleged smuggling networks. Law enforcement in all three are using forgery, fraud, and money laundering charges where direct export-control violations are harder to prove.

The "subsidiary loophole" is now closed, but enforcement effectiveness will depend on how aggressively licences are denied and how quickly intermediaries devise new routes. Analysts at the Council on Foreign Relations have described the export-control policy as "strategically incoherent and unenforceable" as long as Chinese demand remains high and alternative supply chains can be built through third countries .

Singapore is under heightened scrutiny as a transit hub for AI chips. The seizure of a high-profile luxury asset signals that the city-state is cooperating actively with US- and Taiwan-led enforcement despite its role as a global financial center.

Super Micro is at the center but not yet charged. While none of its corporate entities have been charged in any jurisdiction, the detention of its Taiwan employees and the indictment of its co-founder place the company squarely at the center of the most aggressive AI-chip-smuggling crackdown to date.
