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 natural magnesium sulfates are important industrial minerals with a wide range of applications, from agriculture and pharmaceuticals to water treatment and industrial processes. As a key source of magnesium, this industry plays a vital role in supporting various sectors of the economy.

Kieserite and epsomite are naturally occurring minerals that are extracted from deposits found in the earth's crust. The production process typically involves mining the raw material, crushing and screening it to the desired particle size, and then processing it to meet the specific requirements of the end-use application. In some cases, further refining or chemical processing may be required to produce a higher-purity product.

The main inputs for the 253020 kieserite, epsomite industry are the natural mineral deposits containing the magnesium sulfate. Mining equipment, energy sources, and labor are also essential inputs for the extraction and processing of these materials. Depending on the end-use application, additional inputs such as water, chemicals, or specialized machinery may be required.

The primary outputs of the 253020 kieserite, epsomite industry are the refined and processed forms of magnesium sulfate, which are used in a variety of applications. These include 310520 fertilizers, 283329 other inorganic chemicals, 284700 pharmaceutical products, and 282520 magnesium oxide, hydroxide and peroxide. The industry also produces various grades and forms of the mineral salts to meet the specific needs of different industries.
