Quality Management System
we've upgraded to the ISO 9001: 2008 version international quality system.
Customer orientation is one of Sanhao Rubber Company’s guiding principles. Preventing problems and zero defect are our constant pursuit. In order to fulfill the foregoing commitments, we strive to fully implement the following policy:
(1)Good Stuff (2)High Quality (3)High Satisfaction
As a result, our product quality control is extremely strict. In order to boost customers' trust in our products and realize our business philosophy, we have implemented the ISO 9001 quality system since 2007. In 2011, we upgraded to the ISO 9001: 2008 version international quality system. We hope that the quality and service required by this quality assurance model will thoroughly satisfy customers' needs.
