    The "General Principles of Identification Standards for Hazardous Wastes" stipulates that the identification procedures of hazardous wastes shall be carried out in the order of solid waste identification, inventory identification, identification standard identification method and expert identification method, as shown in Figure 1-2

    The expert identification method is used as a supplement to the list appraisal and standard appraisal to make up for the shortcomings of the list appraisal and standard appraisal methods.


    1.


    At present, the country has not issued a unified working procedure.


    (1) Authentication entrustment

    The entrusting party entrusts the identification unit to carry out identification work in written form, and at the same time provides technical information such as raw and auxiliary materials, technological processes, physical and chemical properties and relevant content involved in the environmental impact assessment related to the solid waste to be identified


    (2) Preliminary screening of attributes

    According to the "General Principles of Identification Standards for Solid Wastes", the steps for identifying the solid waste attributes of the identified objects are shown in Figure 1-3

    In 2010, in response to the “Request for Instructions on How to Define Hazardous Wastes and Products” (Luhuanhan [2010] No.


    2.


    If the identified object is solid waste, the identification agency shall determine whether the identified object is included in the current "National Hazardous Waste List"


    After comparing the list, the identified objects are listed as hazardous wastes and do not need to be identified for hazardous characteristics;

    Although the identified objects are not included in the inventory, but may have hazardous characteristics, they need to pass the hazardous waste standard identification method, and determine their hazardous characteristics through sampling, testing and analysis;

    The identified objects are not listed in the list.
