The China new chemical substance notification requires the data submission based on tonnage band. The notifiers should classify the new chemical substances based on hazard class and category (and divisions) standardized by the government concerning the physical hazard, health hazard and environmental hazard, namely the hazard classification should be consistent with provisions in the 26 China GB standards.

The Chinese government published 26 national standards known as the “Safety rules for classification, precautionary labeling and precautionary statements of chemicals” (GB 20576‐2006 to GB 20599‐2006, GB 20601‐2006 and GB 20602‐2006) in 2006 in order to advance the progress of China GHS implementation. The 26 standards define the hazard criteria of each hazard class and other requirements such as hazard statements and pictograms. China is updating the current 26 GHS-related national standards to 28 standards by adding the “aspiration hazard” and “ hazard to the ozone layer”, aiming to be in line with the 4th edition of UN GHS.

The Hazard Classification Sheet for New Chemical Substances contains three aspects of physical hazard, health hazard and environmental hazard. According to the 26 China GB standards, there are 16 sectors of physical hazards, 9 of health hazards and 1 of environmental hazards as below.
