Inorganic Industrial Product Testing

Chemical product testing primarily targets categories such as inorganic chemical products, organic chemical raw materials, fine chemicals, polymer synthetic materials, chemical reagents, and additives. In accordance with national, industry, ISO, ASTM, and other standards, it conducts physicochemical analysis, composition determination, impurity control, and hazardous substance testing. It provides third-party testing technical support for chemical raw material incoming inspection, production process quality control, finished product factory inspection, new product research and development, trade customs clearance, and quality dispute determination.
