Taiwan prosecutors have charged executives at Unimicron, the world's top IC substrate maker, with passing off China-made circuit boards as "Made in Taiwan" — bad news for the company and for Taiwan's electronics export reputation.

• Investigators raided Unimicron's headquarters and a second plant and questioned 14 people over boards allegedly shipped from China and relabeled as Taiwanese.
• The head of the printed circuit board division was released on bail set at NT$15 million, his deputy at NT$12 million, with three others — a plant manager, a factory boss, and a sales staffer — posting smaller amounts.
• Prosecutors say the suspicion is strong enough to charge them with forging documents and falsely marking goods, though none were held in custody.
• Origin-washing cases like this matter more now that US tariffs treat Chinese-made goods far more harshly than Taiwanese ones.

Outlook: Prosecutors say they will widen the investigation, so more charges and possible trade fallout for Unimicron are likely.
