Sulphates; of magnesium

HS v2017 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 chemical manufacturing, making them a crucial component of the global import/export trade ecosystem.

Production process

Magnesium sulphates are typically produced through the reaction of magnesium oxide or magnesium hydroxide with sulphuric acid. The resulting solution is then evaporated and crystallized to obtain the desired magnesium sulphate compound, which can take various forms such as heptahydrate (Epsom salt) or anhydrous magnesium sulphate.

Production inputs

The main inputs required for the production of magnesium sulphates include magnesium-containing raw materials (such as magnesite or seawater), sulphuric acid, and energy sources for the evaporation and crystallization processes. Additionally, specialized equipment like reactors, evaporators, and crystallizers are necessary for the efficient manufacture of these compounds.

Production outputs

Magnesium sulphates produced under HS code 283321 have a wide range of applications, including use as fertilizers 310520 Mineral or chemical fertilizers, nitrogenous, as a source of magnesium in pharmaceuticals 300490 Medicaments, and as a desiccant in various industrial processes 380610 Rosin and resin acids, and derivatives thereof. The output of this industry is often consumed by other industries classified under different HS codes, highlighting the interconnectedness of the global trade landscape.
