Chlorides; of calcium

HS v2022 Code: 282720

About chlorides; of calcium

HS code 282720 covers the classification of calcium chloride, a widely used industrial chemical with a diverse range of applications. As a key component in various manufacturing processes, calcium chloride plays a vital role in the global economy, contributing to the production of numerous consumer and industrial goods. Its versatility and importance make it an essential commodity in international trade and logistics.

Production process

Calcium chloride is primarily produced through the reaction of limestone (calcium carbonate) with hydrochloric acid. This process involves the neutralization of the acid by the limestone, resulting in the formation of calcium chloride and carbon dioxide. The resulting solution is then purified and concentrated to obtain the desired form of calcium chloride, which can be in the form of pellets, flakes, or powder.

Production inputs

The main inputs required for the production of calcium chloride include limestone, hydrochloric acid, and energy sources for the manufacturing process. Additionally, specialized equipment, such as reactors, evaporators, and drying systems, are necessary to facilitate the chemical reaction and purification stages.

Production outputs

The primary output of HS code 282720 is calcium chloride, which finds applications in various industries, including 282720 Chlorides; of calcium, 283329 Inorganic compounds, n.e.c.; including distilled or conductivity water and water of similar purity, and 284700 Peroxides; of sodium or potassium. Calcium chloride is used as a desiccant, a de-icing agent, a concrete additive, and in various chemical processes.
