Kieserite, epsomite (natural magnesium sulphates)

HS code 253020 covers the natural mineral salts known as kieserite and epsomite, which are both forms of magnesium sulfate. These naturally occurring compounds are important industrial and agricultural minerals, with applications ranging from fertilizers and water treatment to pharmaceutical and personal care products. As a key source of magnesium, the 253020 industry plays a vital role in supporting various sectors of the global economy.

Kieserite and epsomite are typically extracted from natural mineral deposits through mining operations. The raw ore is then processed to remove impurities and refine the magnesium sulfate content. This may involve techniques such as crushing, screening, flotation, and chemical treatment. The purified magnesium sulfate is then dried and packaged for distribution to end-users.

The primary inputs for the 253020 industry are the natural mineral deposits containing kieserite and epsomite. Mining equipment, energy sources, and water are also essential resources required for the extraction and processing of these magnesium sulfate compounds. Depending on the level of refinement needed, the industry may also rely on various chemical reagents and additives to purify the final product.

The main outputs of the 253020 industry are the refined kieserite and epsomite products, which are then consumed by a variety of downstream industries. These include the 310000 fertilizer industry, where magnesium sulfate is used as a nutrient and soil conditioner, as well as the 282000 chemical industry, where it is utilized in water treatment, pharmaceuticals, and personal care products. The 253020 industry also supplies magnesium sulfate to other industries, such as 239000 construction materials and 201000 food and beverage.
