Carbonates; potassium carbonate

HS v2022 Code: 283640

About carbonates; potassium carbonate

HS code 283640 covers the classification of potassium carbonate, a vital chemical compound with a wide range of industrial applications. Potassium carbonate is an important inorganic salt that plays a crucial role in various manufacturing processes, from the production of glass and ceramics to the formulation of detergents and pharmaceuticals. As a key component in the chemical industry, potassium carbonate's global demand continues to grow, reflecting its importance in the broader economy.

Production process

Potassium carbonate is typically produced through the reaction of potassium hydroxide and carbon dioxide. This process involves the neutralization of potassium hydroxide with carbon dioxide, resulting in the formation of potassium carbonate. The reaction is carried out in specialized industrial facilities, where the raw materials are carefully measured, mixed, and processed to ensure the desired purity and quality of the final product.

Production inputs

The primary inputs for the production of potassium carbonate include potassium hydroxide, a source of carbon dioxide (such as flue gas or industrial waste streams), and various energy sources to power the manufacturing process. Additionally, specialized equipment, such as reactors, filtration systems, and drying units, are essential for the efficient and reliable production of potassium carbonate.

Production outputs

The primary output of HS code 283640 is potassium carbonate, which finds application in a wide range of industries. Potassium carbonate is used in the production of 281512 Potassium hydroxide for various chemical processes, as well as in the manufacture of 281820 Aluminium oxide, 252310 Cement clinkers, and 284700 Peroxoborates (perborates.
