The process of hazardous chemicals needs to be very careful for the import and export of goods and related enterprises. We believe that our business friends may have some confusion about the hazardous chemical classification and identification report.

So why do you need to classify and identify hazardous chemicals? What is the role of the hazardous chemical classification and identification report? The following is a detailed explanation for you.

▌Background

The full name of the hazardous chemical classification and identification is the identification and classification of physical hazards of chemicals, and the specific regulations were adopted by the General Office of the State Administration of Work Safety on June 24, 2013.

Since September 1, 2013, the "Management Measures for the Identification and Classification of Physical Hazards of Chemicals" has been in effect since September 1, 2013, which clearly explains how hazardous chemicals should be classified, what classifications are available, and the penalties for violating the regulations, so as to ensure the safety and compliance of cargo transportation.

Hazardous chemical classification and identification is based on the characteristics of the chemical (compound, mixture or monomers) itself, according to the relevant standards, to determine whether it is a hazardous chemical, and delineate the possible categories of danger, through a detailed division to complete the classification is the basis of chemical management.

▌Assessment Process

If it is determined to be a dangerous chemical, then it is time to classify and identify the danger of the chemical and judge and assess the danger of the chemical, generally in accordance with the following process.

The existing chemical substances can be compared with the two standards of "List of Dangerous Goods" (GB12268-90) and "Classification and Marking of Commonly Used Dangerous Chemicals" (GB13690-92) to determine their hazard categories and items.

For new chemicals, firstly, literature should be searched and literature data should be used for preliminary assessment and analysis of danger, and then targeted experiments should be conducted; while for those without literature data, comprehensive tests on physical and chemical properties, toxicology, ecology and environment should be conducted, and then based on the Classification and Marking of Commonly Used Dangerous Chemicals (GB13690-92) and Classification and Numbering of Dangerous Goods ( GB6944-86) two standards for classification.

▌Experimental methods and items

Test methods and items need to refer to the UN Recommendations on the Transport of Dangerous Goods.

For the hazard classification of mixtures the above classification procedures and methods are applicable For the hazard classification of mixtures, mixtures are listed in the "List of Dangerous Goods" (GB12268-90) and "Classification and Marking of Commonly Used Dangerous Chemicals" (GB13690-92) with fewer types and literature data.

Some information shows that there is summation of acute toxicity data of mixtures, which can be extrapolated according to the magnitude of concentration of hazardous components when it is difficult to get test data.

In the customs clearance of import and export goods, we will use the hazardous chemical classification identification report, and need to do the territorial commodity inspection when importing, and need to provide the dangerous package certificate when exporting, and the production of dangerous package certificate needs to use the hazardous chemical classification identification report, and also need to issue GHS labels and MSDS of products, which are indispensable for import and export trade! As a professional chemical import and export trade regulations compliance consulting organization, we provide relevant supporting services for the majority of chemical trade and other enterprises, and have a professional team deeply engaged in regulatory research, with le standard to continue to focus on the global chemical regulations of various countries!

Due to the epidemic, customs supervision has been greatly strengthened in recent years, so we hope that all related enterprises will pay attention to it and avoid unnecessary losses due to the inability to meet the compliance in import and export trade!
