Carbonates; potassium carbonate

HS v2017 Code: 283640

About carbonates; potassium carbonate

HS code 283640 covers the classification of potassium carbonate, a vital chemical compound used in a wide range of industries. Potassium carbonate, also known as potash, is an essential raw material for the production of various chemicals, glass, and ceramics. It plays a crucial role in the manufacturing of soaps, detergents, and other household products, as well as in the agricultural sector as a fertilizer. The global potassium carbonate market is expected to grow steadily in the coming years, driven by the increasing demand from various end-use industries.

Production process

Potassium carbonate is primarily produced through the chemical reaction between potassium hydroxide and carbon dioxide. The process typically involves the neutralization of potassium hydroxide with carbon dioxide, resulting in the formation of potassium carbonate. This reaction can be carried out using various methods, including the Solvay process, the Leblanc process, or the ammonia-soda process. The specific production techniques may vary depending on the scale of operation and the desired purity of the final product.

Production inputs

The main inputs required for the production of potassium carbonate include potassium hydroxide, carbon dioxide, and various energy sources (such as electricity or steam) for the chemical reaction and purification processes. Additionally, specialized equipment, such as reactors, evaporators, and crystallizers, are necessary to ensure efficient and high-quality production.

Production outputs

The primary output of HS code 283640 is potassium carbonate, which is then used as a raw material in the production of various other chemicals, such as 283620 Disodium carbonate and 283630 (Sodium hydrogencarbonate (sodium bicarbonate)). Potassium carbonate is also used in the manufacturing of glass, ceramics, and certain types of fertilizers. Additionally, it finds applications in the production of soaps, detergents, and other household products.
