Let me simply explain how to tell the difference: 1. First of all, chemical products all come with an MSDS, and by referring to item 14 of the MSDS, which provides information on cargo transportation, it is possible to determine whether such goods are ordinary goods or hazardous materials. 2. What if there is no MSDS or the MSDS is not very accurate? At this time, it is necessary to use the CSA NO to locate the MSDS for the goods; it can be searched on chemical websites, and in about 90% of cases it can be found. 3. What if the goods are a mixture and there is no separate CAS number, or it cannot be found on the website? If this product is a mixture, it is possible to look up its information using the CAS numbers of its main components; this way, an accurate result can be obtained. If, however, nothing is known about the details of the product at all… ； It is recommended to provide samples and send them to a chemical research institute or a reputable institution for testing the transportation conditions of the goods. By mastering the first two points, you can basically solve 80 to 90 percent of the problems. An MSDS (Material Safety Data Sheet) is a technical document regarding the safety of chemicals; it can also be referred to as a chemical safety sheet or a chemical safety data sheet. It is used by chemical manufacturers and importers to describe the physicochemical properties of chemicals (such as pH value, flash point, flammability, reactivity, etc.). And a document on the potential hazards to the user’s health (such as cancer, birth defects, etc.). In Europe**, the Material Safety Data Sheet/SDS is also known as the Safety Data Sheet/SDS (Safety Data Sheet). The International Organization for Standardization (ISO) uses the SDS terminology, whereas the United States, Canada, Australia, and many countries in Asia use the MSDS terminology. An MSDS is a comprehensive legal document that chemical manufacturing or selling companies are required by law to provide to their customers, detailing the characteristics of the chemicals. It provides sixteen items of information, including the physicochemical properties of chemicals, their flammability and explosiveness, health hazards, safe use and storage, handling in case of leaks, first aid measures, as well as relevant laws and regulations. The MSDS can be prepared by the manufacturer in accordance with relevant regulations. However, to ensure the accuracy and standardization of the report, it is possible to request a professional agency to prepare it. An MSDS is a tool used by chemical manufacturing and supply companies to provide users with basic information on hazards (including transportation, handling and disposal, storage, and emergency procedures). It is stipulated that an MSDS must contain sixteen sections. 1 Chemical product and company identification mainly indicates information such as the name of the chemical product, the name of the manufacturing company, address, postal code, phone number, emergency contact number, fax number, and email address. 2 Composition/information on ingredients: Indicates whether the chemical is a pure substance or a mixture. For pure chemicals, their chemical name or trade name and common name should be provided. For mixtures, the concentration or range of concentrations of the hazardous components shall be given. Whether it is a pure chemical or a mixture, if it contains hazardous components, a Chemical Abstracts Service registry number (CAS number) should be provided. 3 Hazard Summary: This section provides a brief overview of the most significant hazards and effects associated with this chemical, including information on hazard categories, routes of exposure, health hazards, environmental hazards, and fire/explosion risks. 4 First-aid measures refer to the simple procedures for self-rescue or mutual rescue that need to be taken at the scene when workers are accidentally injured, including first-aid measures for eye contact, skin contact, inhalation, and ingestion. 5 Fire-fighting measures mainly refer to information on the physical and chemical hazards associated with chemicals, suitable fire extinguishing agents, unsuitable fire extinguishing agents, and individual protective equipment for firefighters. This includes details such as hazardous properties, fire extinguishing agents and methods, as well as precautions for using them. 6 Emergency response to leaks (accidental release measures) refer to the simple and effective emergency actions, precautions, and elimination methods that can be employed at the scene in the event of a chemical leak, including emergency procedures, protection for emergency responders, environmental protection measures, and methods for eliminating the hazard. 7 Handling and storage refers mainly to information on the handling and safe storage of chemicals, including safety precautions during handling operations, as well as conditions and precautions for safe storage. 8 Exposure controls/personal protection refer to the protective methods and measures taken to safeguard workers from the hazards of chemicals during the processes of producing, handling, transporting, and using such chemicals. These include: maximum allowable concentration, engineering controls, respiratory protection, eye protection, body protection, hand protection, and other protective requirements. 9 Physical and chemical properties describe information related to the appearance and physical and chemical characteristics of chemicals, including: appearance and state, pH value, boiling point, melting point, relative density (water=1), relative vapor density (air=1), saturated vapor pressure, heat of combustion, critical temperature, critical pressure, octanol/water partition coefficient, flash point, ignition temperature, explosion limits, solubility, main uses, and other specific physical and chemical properties. 10 Stability and Reactivity: This section provides information on the stability and reactivity of chemicals, including stability, incompatible substances, conditions to be avoided to prevent contact, polymerization hazards, and decomposition products. 11 Toxicological information provides data on the toxicity of chemicals, including acute toxicity under various exposure conditions (LD50, LD50), irritancy, sensitization, subacute and chronic toxicity, as well as mutagenicity, teratogenicity, and carcinogenicity. 12 Ecological information primarily describes the environmental and ecological effects, behavior, and fate of chemicals, including biological effects (such as LD50), biodegradability, bioaccumulation, environmental migration, and other harmful environmental impacts. 13 Disposal refers to the safe methods for dealing with chemically contaminated packaging and chemicals that are no longer useful, including the disposal methods and precautions involved. 14 Transport information refers mainly to the requirements for the packaging and transportation of chemicals domestically and internationally, as well as the classification and numbering of transportation regulations. This includes: hazard material numbers, packaging categories, packaging markings, packaging methods, UN numbers, and precautions for transportation. 15 Regulatory information mainly refers to the legal provisions and standards related to chemical management. 16 Other information primarily provides additional data that is important for safety, including: references, date of form completion, department that filled out the form, and the unit responsible for data verification.
