Carbonates; disodium carbonate

HS v2017 Code: 283620

About carbonates; disodium carbonate

HS code 283620 covers the classification of disodium carbonate, a widely used chemical compound that plays a crucial role in various industries. As a key component in the production of glass, detergents, and water treatment, disodium carbonate, also known as soda ash, is an essential commodity in the global economy. Its versatility and high demand make it an important player in the broader chemical industry.

Production process

Disodium carbonate is primarily produced through the Solvay process, a well-established industrial technique. This process involves the reaction of ammonia, carbon dioxide, and brine (sodium chloride solution) to create sodium bicarbonate, which is then calcined (heated) to produce the final product, disodium carbonate.

Production inputs

The main inputs required for the production of disodium carbonate include sodium chloride (brine), ammonia, and carbon dioxide. Additionally, the process requires specialized equipment such as reaction vessels, evaporators, and calcination furnaces to facilitate the various stages of production.

Production outputs

The primary output of HS code 283620 is disodium carbonate, which is widely used in the manufacturing of 281512 (Sodium hydroxide (caustic soda)) and 281511 (Sodium hydroxide in aqueous solution (soda lye or liquid soda)) as well as in the production of 701000 Glass and glassware, 340220 Washing and cleaning preparations, and 281990 Inorganic chemicals n.e.c..
