If a mixture contains some hazardous chemicals, does that mean the substance itself is a hazardous chemical?

Don’t say it has to be followed strictly; what’s needed is a basis. I’ve summarized it; if you think it’s incorrect, feel free to reply. According to the Catalogue of Hazardous Chemicals (2015 edition), hazardous chemicals are defined as highly toxic chemicals and other chemicals that possess properties such as toxicity, corrosivity, explosiveness, flammability, or oxidizing ability, and that pose risks to human health, facilities, and the environment. For example: if a mixture contains a very low level of hazardous chemicals, such as 1%, then the mixture as a whole may not possess properties such as toxicity, corrosivity, explosiveness, flammability, or oxidizing ability, and it will pose no threat to humans, facilities, or the environment. (Can this be authenticated by a third-party agency?) ) Then this mixture does not belong to hazardous chemicals. Conversely, it is a hazardous chemical; if the owner does not agree, you can ask him to have it tested. China adopts a catalog system for the management of hazardous chemicals; those listed in the Catalog are subject to stringent regulation through measures such as administrative permits, in accordance with the relevant laws and regulations. For mixtures and hazardous chemicals not listed in the Catalogue, in order to fully understand the hazardous properties of such chemicals within China, the country has implemented a registration system as well as a identification and classification system for hazardous chemicals. Enterprises are required to carry out identification and classification in accordance with the \"Administrative Measures for the Identification and Classification of Physical Hazards of Chemicals\" (Order No. 60 of the State Administration for Work Safety) and other relevant regulations. If a substance is identified as a hazardous chemical, it must be registered in accordance with the \"Administrative Measures for the Registration of Hazardous Chemicals\" (Order No. 53 of the State Administration for Work Safety), so as to fully comprehend the hazards associated with those chemicals from the outset and ensure their safe use.
Whether the mixture constitutes a hazardous chemical depends on whether it contains components such as flammable and explosive substances, hazardous chemicals, or radioactive materials that can pose a threat to human safety and property. The \"Work Safety Law of the People’s Republic of China\" and the \"Regulations on the Safety Management of Hazardous Chemicals\" provide detailed provisions.
What was said upstairs is correct; after all, anything that poses a threat to society and the environment should be classified as a hazardous chemical.
According to the regulations on hazardous chemicals, this should also be classified as a hazardous chemical. . In any case, whether it is a hazardous chemical or not is determined according to the legal criteria of whether it is flammable, explosive, corrosive, or radioactive
There is no basis for this; according to Order No. 60 of the State Administration for Work Safety, titled \"Administrative Provisions on the Assessment and Classification of the Physical Hazards of Chemicals\", the following chemicals shall undergo assessment and classification of their physical hazards: (1) Chemicals that contain one or more components listed in the Catalogue of Hazardous Chemicals, but whose overall physical hazards have not yet been determined； (II) Chemicals not listed in the Catalogue of Hazardous Chemicals, for which physical hazards have not yet been determined ； (III) Chemicals intended for scientific research or product development, with an annual production volume or usage amount exceeding 1 ton, and for which the physical hazards have not yet been determined. The chemicals you mentioned require this to be done.
Thank you for the reply, but this refers to physical hazards, and it seems a bit incomplete to me.

According to Article 5 of Document No. An Jian Zong Tang Guan San (2015) 80, titled “Notice from the General Office of the Work Safety Administration on Issuing the Implementation Guidelines (Trial) for the Hazardous Chemicals Catalogue (2015 Edition),” mixtures whose main components are all hazardous chemicals listed in the Catalogue, and whose combined mass or volume ratio of these components is 70% or more (with exceptions for those that do not meet the criteria for being classified as hazardous chemicals), can be regarded as hazardous chemicals and should be managed accordingly. When handling relevant safety permits, the safety supervision authorities shall indicate the trade name of the mixture as well as the content of its main components. Article 6 states that for mixtures whose main components are all hazardous chemicals listed in the Catalogue, but whose combined mass or volume ratio is less than 70%, or for chemicals whose hazardous properties have not yet been determined, the manufacturing or importing enterprises shall conduct assessments and classifications in accordance with the “Measures for the Assessment and Classification of the Physical Hazards of Chemicals” (Order No. 60 issued by the Work Safety Administration) and other relevant regulations. If such substances meet the criteria for being classified as hazardous chemicals, they shall be registered in accordance with the “Measures for the Registration of Hazardous Chemicals” (Order No. 53 issued by the Work Safety Administration); however, no additional safety permit procedures are required. In summary, if the concentration of hazardous chemicals is 70% or higher, it is considered a hazardous chemical; if it is below 70%, assessments must be carried out in accordance with relevant regulations.
