Taiwan’s Keelung District Prosecutors Office stated that the searches were part of an ongoing investigation into the alleged illegal export of Super Micro servers. Authorities also raided Taiwanese data center operator Chief Telecom Inc. and Super Micro distributor Albatron Technology Co., according to the report.

Focus On AI Chip Exports

The latest searches mark an expansion of Taiwan’s first public crackdown on the diversion of AI chips after years of pressure from Washington to strengthen restrictions on China’s access to advanced technology. The U.S. has long limited exports of advanced AI chips to China over concerns the technology could support Beijing's military capabilities.

Taiwan currently does not classify AI chip exports to China as a criminal offense, stated the Bloomberg report, adding that authorities have still warned exporters that such shipments could violate U.S. rules, leaving prosecutors to rely on other local laws when pursuing suspected smugglers. Taipei is now considering making such exports a criminal offense, which would give investigators broader powers to pursue illegal shipments, said the report.

Investigation Builds On Earlier Arrests

The latest enforcement action follows arrests made in May, when authorities detained three individuals accused of falsifying export documents tied to Super Micro servers carrying Nvidia AI chips. The Keelung District Prosecutors Office said the individuals searched during Monday's raids have also been summoned for questioning.

Taiwan is also considering strengthening its AI chip export controls to better align with U.S. restrictions.
