The classification of chemicals is an important task, but it has not been given the attention it deserves. This is evidenced by the lack of sufficient materials for classification. It becomes quite difficult without a proper classification table to easily choose from millions of available products. The article below is a compilation and an overview from Cường Thịnh Chemical Company that we would like to share with our customers. Please refer to it!
1. Chemical Classification According to Circular 04/2012/TT-BCT:
Chemicals are classified according to the Ministry of Industry and Trade regulations.
According to Article 5 of Circular 04/2012/TT-BCT by the Ministry of Industry and Trade, chemicals are classified into various levels, including: material hazards, health hazards to humans, and environmental hazards. Specific information is as follows:
-
Material Hazards:
- Explosive substances
- Flammable gases
- Flammable aerosols
- Oxidizing gases
- Compressed gases
- Flammable liquids
- Flammable solids
- Self-reactive substances
- Flammable liquids
- Flammable solids
- Self-heating solids
- Self-heating compounds
- Compounds that release flammable gases when in contact with water
- Oxidizing liquids
- Oxidizing solids
- Organic peroxides
- Corrosive to metals.
-
Health Hazards to Humans:
- Acute toxicity
- Skin corrosion
- Eye damage
- Respiratory or skin sensitizers
- Germ cell mutagenicity
- Carcinogenicity
- Reproductive toxicity.
-
Environmental Hazards:
- Water environment
- Effects on the ozone layer.
2. Classification of Industrial Chemicals by Purpose:
Basic chemicals produced in large quantities: Industrial chemicals are commonly categorized into three types: basic chemicals, specialty chemicals, and consumer chemicals.
- Basic Chemicals: These are compounds produced in large quantities. They are primarily used in the chemical industry and other industries. These mixtures are derived from petroleum and are called petrochemicals, polymers, and basic inorganic chemicals.
- Specialty Chemicals: These industrial chemicals are used to protect crops, in paints, printing inks, and pigments. They are also widely used in the textile, paper, and engineering industries. Some examples of specialty chemicals are adhesives, cleaning materials, cosmetic additives, construction materials, food additives, fragrances, industrial gases, lubricants, and polymers.
- Consumer Chemicals: These are end products that serve consumer purposes. This category includes cleaning products, soaps, synthetic chemicals for hygiene, cosmetics, and perfumes.
3. Classification of Chemicals by the Degree of Chemical Bond:
Chemicals are simply a combination of various substances.
- Pure Chemicals: These are chemicals that do not form bonds with other substances or are not contaminated. Examples include diamond (carbon), gold, table salt (sodium chloride), and refined sugar (sucrose). These are rarely encountered in pure form, as they typically exist as mixed compounds.
- Synthetic Chemicals: Synthetic chemicals can be understood as the combination of several different substances to create a new compound. They contribute to the development of the food and pharmaceutical industries. They enhance color, flavor, and texture in food. In pharmaceuticals, various substances are combined to treat different disorders.

4. Classification of Chemicals by Specific Applications:
Chemicals used in pharmaceutical preparation: Due to their excellent characteristics and adaptability, chemicals are applied in many important sectors of social life, including:
- In biochemical research
- In the food and pharmaceutical industries
- In environmental treatment
- In agriculture
- In geochemistry
- In forensic science
