According to the Regulations on the Safety Management of Hazardous Chemicals, hazardous chemicals refer to those highly toxic chemicals and other chemicals that are toxic, corrosive, combustion, combustion-supporting, etc., and are harmful to the human body, facilities and the environment. According to the Announcement of the General Administration of Customs [2020] No. 129 on Issues Concerning the Inspection and Supervision of Import and Export of Hazardous Chemicals and Their Packaging, the Customs has implemented a strict inspection system for the import and export of hazardous chemicals listed in the National Catalogue of Hazardous Chemicals (the latest version). At present, we are using the 2015 version of the Catalogue of Hazardous Chemicals. This version is very detailed in defining and classifying hazardous chemicals.
Hazard Disclosure Labels
Hazardous chemical labels, which are "warning lights" attached to chemical packaging, are a combination of words, pictograms and codes, like a guardian, always reminding people to pay attention to safety. It must comply with GB15258 and GB30000 series standards, and contain at least six contents, including chemical identification, pictograms, signal words, hazard statements, precautionary instructions and business identification. Each of them has its own role to play and work together to ensure safety. This label acts like a responsible guide to give us clear and timely help no matter what problems we encounter when using chemicals. Therefore, we must use it in accordance with the regulations so that its value can be fully realized.
