Chlorides; of magnesium

HS v2022 Code: 282731

About chlorides; of magnesium

HS code 282731 covers the classification of magnesium chlorides, an important chemical compound with a wide range of industrial applications. Magnesium chloride is a key component in various manufacturing processes, playing a crucial role in the production of other chemicals, construction materials, and even food products. As a versatile and widely-used substance, the global trade and production of magnesium chlorides are significant, contributing to the broader chemical and industrial sectors.

Production process

Magnesium chloride is typically produced through the reaction of magnesium oxide or magnesium hydroxide with hydrochloric acid. The process involves the dissolution of the magnesium-based raw material in the acid, followed by the evaporation of water to crystallize the magnesium chloride. Depending on the desired purity and application, the resulting crystals may undergo further purification steps, such as recrystallization or ion exchange.

Production inputs

The primary inputs for the production of magnesium chloride include magnesium oxide or magnesium hydroxide, which serve as the source of magnesium, and hydrochloric acid, which is used to facilitate the chemical reaction. Additionally, the production process may require various types of equipment, such as reactors, evaporators, and crystallizers, as well as utilities like water and energy sources.

Production outputs

The primary output of HS code 282731 is magnesium chloride, which finds applications in a wide range of industries. Magnesium chloride is used in the production of 282739 Other chlorides, 283329 Other inorganic bases, and 283329 Other inorganic bases. It is also used in the construction industry as a de-icing agent, in the food industry as a coagulant, and in various other applications, such as in the production of textiles, pharmaceuticals, and agricultural products.
