Taiwanese prosecutors raided Unimicron's Taoyuan headquarters and Zhongli plant on August 28 following allegations of illegal product relabeling. The company is accused of shipping China-made PCBs to Taiwan and falsely labeling them as Taiwanese products.
Fourteen employees were questioned as suspects, while four others served as witnesses. The PCB general manager, Wang, and deputy general manager, Wu, were released on bails of NT$15 million and NT$12 million for suspected forgery and false labeling crimes.
The probe impacts a key supplier for Nvidia, Intel, Google, and Amazon. U.S. Customs applies a 40% tariff on goods transshipped to evade duties, and the White House has flagged Taiwan as an elevated risk for such illegal activity to bypass China trade rules.
