What is China GHS?

The "Globally Harmonized System of Classification and Labelling of Chemicals (GHS)" is a system created by the UN to address the classification of chemicals by types of hazard and harmonize hazard communication elements, including labels and safety data sheets.
As GHS is non-legally binding in the member countries of the United Nations, many countries and regions have published their own regulations or standards to implement GHS.

For example, the GHS criteria were introduced into Europe via the Regulation (EC) No 1272/2008 on the Classification, Labeling and Packaging of substances and mixtures (CLP).
In China, GHS Standard consists from mandatory (GB) and voluntary (GB/T) national standards.

China GHS covers the requirements for Classification, Labelling and Packing as well as Safety Data Sheets of hazardous chemicals since May 01, 2011. China defines "hazardous chemicals" in the State Council Decree 591, a supreme legislation on hazardous chemicals management and the primary legal base of China GHS enforcement.
Hazardous chemicals listed in the Catalogue of Hazardous Chemicals will be subject to extra requirements, for example, product licenses, operation licenses, safe use permits, etc.
