This service is oriented to chemical raw material manufacturers, traders, and downstream application enterprises, building a testing system covering all indicators of raw materials. Physical and chemical property testing includes purity analysis, component content determination, stability testing, and functional testing such as temperature resistance, acid and alkali resistance, and wear resistance. High-precision testing equipment such as high-performance liquid chromatography, infrared spectrometers, and tensile testing machines are adopted to issue accurate testing reports. Compliance certification services focus on mainstream domestic and foreign market access standards, including China’s national standards (GB), EU REACH regulations, US FDA certification, and RoHS directives. We assist enterprises in completing raw material toxicology testing, environmental indicator testing, and the compilation of Material Safety Data Sheets (MSDS). For trading enterprises, we provide raw material import and export compliance testing to avoid policy risks in cross-border trade; for manufacturing enterprises, we provide ex-factory quality control testing to help enterprises establish standardized quality inspection processes. At the same time, we provide customers with testing result interpretation and rectification suggestions. For example, if the heavy metal content of raw materials exceeds the standard, we will guide enterprises to optimize production processes or adjust raw material procurement channels to ensure that products meet market access requirements.
