What is the difference between MSDS and TDS? MSDS is a comprehensive legal document on the characteristics of chemicals provided by chemical production or marketing enterprises to customers according to legal requirements. It provides 16 items of chemical physical and chemical parameters, flammability and explosion properties, hazards to health, safe use and storage, leakage disposal, first aid measures and relevant laws and regulations. MSDS can be prepared by the manufacturer according to relevant rules. However, in order to ensure the accuracy and standardization of the report, you can apply to a professional organization for preparation.

Differences between MSDS and TDS:

1. The former is the safety instructions, and the latter is the technical instructions.

2. MSDS (Material Safety Data Sheet) refers to the chemical safety instructions, which can also be translated into the chemical safety technical instructions or chemical safety data sheets. It is a document for chemical manufacturers and importers to clarify the physical and chemical properties of chemicals (such as PH value, flash point, flammability, reactivity, etc.) and the possible hazards to the health of users (such as carcinogenesis, teratogenicity, etc.).

3. T.D.S. is the abbreviation of Total Dissolved Solids. The Chinese name is total dissolved solids, which is the total amount of solids dissolved in water. For example, the weight ratio of minerals in water. The dissolved solids in water are mainly calcium and magnesium, and are not measurable pollutants. The unit of measurement is (parts per millions) or mg/L (milligram/liter), which indicates how many milligrams of total soluble solids are dissolved in 1 liter of water.
