Carbonates; disodium carbonate

HS v2022 Code: 283620

About carbonates; disodium carbonate

HS code 283620 covers the classification of disodium carbonate, a widely used industrial chemical compound. Disodium carbonate, also known as soda ash, is a key ingredient in the production of glass, detergents, and various other chemical products. As a versatile and essential material, the disodium carbonate industry plays a crucial role in supporting a diverse range of manufacturing and industrial sectors, contributing significantly to the global economy.

Production process

Disodium carbonate is primarily produced through the Solvay process, a multi-step chemical reaction involving the interaction of ammonia, carbon dioxide, and brine (sodium chloride solution). The key steps involve the conversion of sodium chloride to sodium bicarbonate, followed by the calcination of the sodium bicarbonate to produce the final disodium carbonate product.

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, filtration systems, and calcination furnaces. Energy sources, such as natural gas or electricity, are also essential for powering the various stages of production.

Production outputs

The primary output of HS code 283620 is disodium carbonate, which is then consumed by a wide range of industries. Some of the major consumers of disodium carbonate include the 281511 (Sodium hydroxide (caustic soda)) industry, the 320530 Colours for retail sale industry, and the 252310 Cement clinkers industry. Disodium carbonate is also used in the production of 283630 (Sodium hydrogencarbonate (sodium bicarbonate)) and various other chemical products.
