Quality Control

YST relies on its strict quality control system to provide an important basis for import and export of fluorspar. In Mongolia (the origin), YST owns a fluorspar laboratory where fluorspar is classified according to its content of calcium fluoride and particle size. In the warehouse located at Tianjin Port Free Trade Zone, dedicated personnel will be responsible for orders placed by the clients, ensuring dedicated management of all the links including processing, separation, packaging, weighing, testing, sample retention, vanning and container gate-in. The quality management system enables us to win the recognition of the clients one after another. Third-party inspection companies are welcome to have an on-site inspection.
