With the joint efforts and cooperation of all departments, our company has been implementing the ISO9001:2015 Quality Management System for half a year, which has promoted our management to a new level. On November 30, 2021, our company successfully passed the ISO9001 Quality Management System certification audit. This certification was verified through on - site audits by an expert audit team from an authoritative third - party certification center, marking that our company's quality management system has been recognized by the third - party certification body. ISO is the English abbreviation of the International Organization for Standardization. Since March 2021, our company has fully launched the introduction and certification work of the ISO9001 Quality Management System. By applying the concepts and standards of the ISO9001 Quality Management System, we have standardized the management of relevant departments such as the Sales Department, General Affairs Department, Marketing Department, Purchasing Department, and Quality Department. This has made our work clearer, the processes more reasonable, and effectively improved the overall work efficiency and management level of the company.
