Dithionites and sulphoxylates; of sodium

HS code 283110 covers the production and trade of dithionites and sulphoxylates, specifically those of sodium. These compounds are essential chemical agents used in a variety of industries, including textile processing, paper manufacturing, and water treatment. As a key component in many industrial processes, the global market for dithionites and sulphoxylates is substantial and continues to grow in line with the expanding needs of the manufacturing sector.

The production of dithionites and sulphoxylates of sodium typically involves the reduction of sulfur dioxide (SO2) in the presence of a reducing agent, such as sodium hydrosulfite. This process is carried out under controlled temperature and pressure conditions to ensure the desired chemical reactions take place. The resulting sodium dithionite or sodium sulphoxylate is then purified and prepared for distribution to various end-use industries.

The main inputs required for the production of HS code 283110 products include sulfur dioxide, sodium hydroxide or other reducing agents, and energy sources to power the manufacturing equipment. Specialized processing machinery, such as reactors, filters, and drying units, are also essential for the efficient production of these chemicals. Additionally, strict quality control measures and environmental compliance protocols are necessary to meet industry standards and regulations.

The primary outputs of HS code 283110 are sodium dithionite and sodium sulphoxylate, which find widespread application in various industries. These compounds are commonly used as reducing agents, bleaching agents, and antioxidants in textile processing, paper manufacturing, and water treatment applications. The outputs of HS code 283110 may be further processed or incorporated into the production of other chemical products, such as 283090 Sulphides; polysulphides, whether or not chemically defined and 283220 Sulphites; thiosulphates.
