Chlorides; of calcium

HS v2017 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, the global calcium chloride market plays a vital role in supporting industries such as construction, oil and gas, and chemical production, contributing significantly to the broader economy.

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 with the limestone, resulting in the formation of calcium chloride and carbon dioxide. The calcium chloride solution is then purified and concentrated through evaporation, crystallization, and drying techniques to obtain the desired product form.

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 units are necessary to facilitate the various stages of production.

Production outputs

The primary output of HS code 282720 is calcium chloride, which finds applications in a wide range of industries. It is commonly used as a desiccant, a deicing agent, a concrete additive, and a water treatment chemical. The calcium chloride produced under this code may be further processed or consumed by industries classified under other HS codes, such as 283640 Calcium carbonates, 281511 (Sodium hydroxide (caustic soda)), and 251010 Natural calcium phosphates and natural aluminium calcium phosphates, among others.
