Quality Policy

To offer a more high-quality, more efficient product, the Nichicon Group has persisted in quality control and has built up an original production management system which enables us to check when, where, which product, and under what situation our products are being made, aiming at zero defectives.

Besides all factories at home and abroad already having obtained the certification of ISO 9000 Series, ISO/TS 16949, the international standard of the auto industry, has been obtained at one overseas and five domestic manufacturing facilities.

Response to Quality Complaints

Nichicon established a system for responding to complaints. Under the system, we understand the information correctly; respond to customers with quick, fair, and proper treatment; feed the information back to the manufacturing process; and prevent a recurrence.
