On November 6th, 1997, we obtained quality management system ISO9001 certification for polycarbonate resin products. In November, 2001, we expanded the target product to all the resins with a scope "Design, Development, Sales, and Production Consignment of Engineering Plastics."

In November, 2002, we obtained ISO14001 certification.

In November, 2004, we integrated ISO9001 and ISO14001, to build an integrated management system, including responsible care, risk management, and internal control. We effectively use it as a business management tool, and put effort on providing products that satisfy all the customers, with continual improvement.
