- Textile and Footwear Industry: Vietnam is a global production center for textiles, garments and footwear, and requires a large amount of chemical products such as dyes, auxiliaries and adhesives.
- Electronic manufacturing industry: The production of semiconductors and batteries relies on high-purity chemicals (such as etching agents, electroplating solutions, etc.).
- Water Treatment and Environmental Protection: The demand for industrial wastewater treatment has driven the use of flocculants (such as PAC) and phosphates (such as trisodium phosphate).
- Agriculture and Feed: There is a large demand for fertilizers, pesticides and feed additives (such as calcium hydrogen phosphate).
- processing: -grade phosphates (such as trisodium phosphate) are used for anti-corrosion, pH regulation, etc.
Rely heavily on imports: Vietnam's domestic chemical production capacity is limited. About 70% of its chemical raw materials need to be imported (mainly from China, South Korea and Japan).
China is the largest supplier: Due to its price advantage and geographical proximity, China accounts for over 40% of Vietnam's chemical imports (such as phosphate, aluminium sulfate, etc.).
Popular imported categories:
- Basic chemicals (soda ash, sulfuric acid)
- Water treatment chemicals (PAC, polyferric chloride)
- (citric acid, phosphate)
Opportunity:
- The Vietnamese government is promoting industrialization (the "Industrial Development Plan 2030"), and the demand for chemical industry continues to grow.
- The tightening of environmental protection regulations has driven up the demand for green chemicals, such as phosphorus-free water treatment agents.
Challenge:
- Localized competition: Some Vietnamese enterprises have begun to invest in chemical production (such as the Vinachem Group).
- Trade barriers: Vietnam imposes anti-dumping duties on certain chemical products (such as HFC refrigerants made in China).
