Taiwanese PCB maker Unimicron under investigation for allegedly relabeling China-made boards

Taiwanese prosecutors raided Unimicron's headquarters and a plant on August 28, questioning 14 employees as suspects in an alleged scheme to disguise China-made PCBs as Taiwanese products. The company, a major supplier to Nvidia, Intel, Google, and Amazon, faces potential U.S. tariffs of 40% if the origin fraud is confirmed. Unimicron says it is cooperating and does not expect a material impact on operations.

The August 28 raid targeted Unimicron's Guishan headquarters and a Zhongli plant, with prosecutors questioning 18 individuals total. Bail amounts varied widely, from roughly $473,000 for the PCB general manager down to $9,500 for others, while nine suspects were released without conditions. The alleged violations involve Taiwan's criminal code provisions on forged private documents and false origin labeling.

The probe unfolds against Washington's 40% tariff on goods transshipped to evade duties, a penalty that would fall on American importers.
