Prosecutors in Taiwan have charged senior staff at circuit board maker Unimicron with faking the origin labels on Chinese-made products, a hit to one of Taiwan's biggest electronics suppliers.

• Unimicron is accused of shipping circuit boards made in China back to Taiwan and relabeling them as made in Taiwan.
• Investigators raided the company's headquarters and a second plant, and questioned 14 people including the head of its circuit board division.
• Five, among them the division president, were released on bail, with the largest bond set at NT$15 million.
• The charges include forgery and falsely marking goods, both criminal offenses in Taiwan.
• "Made in Taiwan" labels matter more than ever as US tariffs treat Chinese goods far more harshly than Taiwanese ones.

Outlook: Prosecutors say the investigation will widen, so more employees and possibly other suppliers could be pulled in.
