Taiwanese prosecutors detained two senior executives of Jiin Ming Industrial Co., a Taipei Exchange-listed drone manufacturer, on suspicion that the company installed banned mainland Chinese semiconductors and camera lenses in unmanned aircraft sold to the military and then submitted false certificates of origin to pass acceptance inspections.
Jiin Ming confirmed in a Monday stock filing that President Chien and Sales Director Chen were detained after overnight questioning. The Taoyuan District Prosecutors Office said the firm and a subsidiary, Ying Sheng International, won multiple defence procurement contracts but allegedly violated rules barring Chinese-made components in military-grade drones.
What investigators allege
According to the prosecutors’ account, Jiin Ming fitted prohibited chips and lenses into delivered aircraft, then used falsified paperwork so military inspectors would approve the platforms. The Justice Investigation Bureau assisted the probe, which centres on national-security procurement rules tightened as cross-strait tensions rise.
After a court hearing in the early hours of 9 October, prosecutors secured two-month detention for Chien and Chen, barring visits and mail. Other individuals questioned were released. The company has not publicly stated how many airframes were involved, which units received them, or whether in-service drones will be recalled for inspection.
Why the case matters for defence supply chains
Taipei has poured budget into domestically built drones while insisting that sensitive electronics cannot come from mainland suppliers. Any proven breach would undermine confidence in acceptance testing and could trigger audits across other unmanned-system vendors.
The detentions land days after Defence Minister Wellington Koo told lawmakers the Coast Guard would lead responses to Chinese maritime militia incursions, with the navy in support—another signal that Taipei is tightening both external deterrence and internal compliance. Investors punished Jiin Ming shares before the opening bell on Monday as traders weighed possible contract cancellations and regulatory penalties.
Next steps
Prosecutors are pursuing National Security Act allegations alongside charges tied to false business records and aggravated fraud involving three or more people. Military officials have not detailed operational impact, but opposition legislators are likely to demand a full inventory of Jiin Ming deliveries and independent testing of components.
If courts uphold the detention, investigators will comb financial records and supplier invoices to trace how Chinese parts entered the production line. The case could also feed Legislative Yuan debate over stiffer criminal penalties for defence contractors that mislabel foreign content—especially as Taiwan expands drone production for island-wide surveillance and coastal defence.
