Sulphates; of magnesium

HS v2022 Code: 283321

About sulphates; of magnesium

HS code 283321 covers the classification of magnesium sulphates, a group of important inorganic compounds with a wide range of industrial and commercial applications. Magnesium sulphates are essential raw materials for various industries, including agriculture, pharmaceuticals, and water treatment, making them a crucial component of the global chemical supply chain.

Production process

Magnesium sulphates are typically produced through the reaction of magnesium oxide or magnesium hydroxide with sulphuric acid. The resulting solution is then crystallized, filtered, and dried to obtain the final product. Depending on the specific application, different hydration levels (anhydrous, monohydrate, or heptahydrate) may be produced.

Production inputs

The main inputs required for the production of magnesium sulphates include magnesium-containing raw materials, such as 251910 Magnesium oxide or 281511 Magnesium hydroxide, as well as sulphuric acid. Additionally, energy sources, water, and specialized equipment for crystallization, filtration, and drying are necessary for the manufacturing process.

Production outputs

Magnesium sulphates produced under HS code 283321 have a wide range of applications. They are used as fertilizers, as well as in the production of 300490 Medicaments, 282520 Magnesium chloride, and 283525 Copper sulphates. The output of this industry is an essential input for various other industries, making it a crucial component of the global chemical supply chain.
