In December, after the on-site guidance and verification by the expert group of certifying authority, our company successfully renewed ISO 9001:2015. Passing through more strict certificate renewal process is the recognition of our existing quality management system and customer service system by the audit institution.



We will continuously optimize and improve our quality management and service to provide customers with better products and service.
