Taiwanese prosecutors raided Unimicron’s facilities in Taoyuan on August 31, 2026, investigating the world’s second-largest PCB manufacturer for allegedly falsifying the origin of chip substrates supplied to Nvidia and Intel. Suspects were released on bail as authorities examine claims of „origin washing,” where Chinese-made components are misrepresented as Taiwanese to avoid U. S. tariffs. The probe follows heightened U. S. scrutiny of supply chain transparency under the CHIPS Act enforcement framework. Unimicron, a critical supplier of advanced packaging materials for AI chips, faces potential penalties if found guilty of circumventing trade rules. U. S. customs data shows a surge in PCB imports from Taiwan linked to Chinese factories, prompting customs officials to flag inconsistencies in documentation. Industry analysts note that over 60% of Unimicron’s revenue comes from U. S.-based tech firms, making compliance critical.

How Origin Washing Undermines Trade Compliance Origin washing involves rerouting goods through intermediate countries to disguise their true source, often to evade tariffs or sanctions. In this case, prosecutors allege that Unimicron submitted false certificates of origin for PCBs manufactured in mainland China, labeling them as Taiwanese-made. Such practices violate U. S. Customs and Border Protection regulations, which require accurate country-of-origin marking for all imported goods. If proven, the fraud could trigger retroactive duties dating back years, significantly impacting Unimicron’s financials. What Are the Potential Financial Consequences? If U. S. authorities confirm the allegations, Unimicron could face tariffs as high as 40% on affected imports under Section 301 trade actions. This would dramatically increase costs for Nvidia and Intel, potentially disrupting AI chip production timelines.

The company’s stock dropped 12% in after-hours trading following the raid news. Legal experts warn that penalties may include fines, exclusion from U. S. government contracts, and mandatory supply chain audits lasting up to three years. Frequently Asked Questions What specific products are under investigation? The probe focuses on multilayer printed circuit boards and chip substrates used in AI accelerators and data center processors supplied to Nvidia and Intel. How does origin washing violate U. S. trade law? It violates the Trade Agreements Act and customs regulations by providing false origin information to avoid tariffs and gain unfair trade advantages. Could this affect global AI chip supply chains? Yes, as Unimicron supplies over 30% of high-end PCBs for AI hardware, any disruption could delay production for major tech firms reliant on its components.
