The GLOBALLY HARMONIZED SYSTEM standardizes the classification and labeling of chemicals worldwide.
On May 1, 2011, the GHS system was enforced in China. The GHS addresses classification of chemicals by types of hazard and proposes harmonized hazard communication elements, including labels and safety data sheets. It aims at ensuring that information on physical hazards and toxicity from chemicals be available in order to enhance the protection of human health and the environment during the handling transport and use of these chemicals.
The GHS also provides a basis for harmonization of rules and regulations on chemicals at national, regional and worldwide level.
