About natural magnesium carbonate (magnesite); fused magnesia; dead-burned (sintered) magnesia, whether or not containing small quantities of other oxides added before sintering; magnesium oxide, pure or not

HS code 2519 covers a range of magnesium-based products that are essential raw materials for various industries. Magnesium carbonate, also known as magnesite, is a naturally occurring mineral that is mined and processed for use in a variety of applications. Fused magnesia and dead-burned magnesia are produced through high-temperature processing of magnesite, and magnesium oxide is a versatile compound derived from these materials. These products play a crucial role in industries such as 6815 Manufacture of non-metallic mineral products, 2311 Manufacture of flat glass, and 2320 Manufacture of refractory products.

Production process

The production of the products covered under HS code 2519 involves several key steps. Magnesite is mined from natural deposits and then crushed, ground, and purified to obtain high-quality magnesium carbonate. Fused magnesia is produced by heating magnesite in an electric or fuel-fired furnace, which causes the material to melt and then solidify into a dense, crystalline structure. Dead-burned magnesia is created by heating magnesite to even higher temperatures, typically around 1,700°C, which results in a material with superior refractory properties. Magnesium oxide is obtained by further calcining magnesite or other magnesium-containing materials.

Production inputs

The main inputs required for the production of HS code 2519 products are magnesite, the primary raw material, as well as energy sources such as electricity or fossil fuels to power the high-temperature processing. Specialized equipment, including crushers, grinders, and furnaces, is also essential for the various production stages. Additionally, the industry may require small quantities of other mineral additives to achieve specific product characteristics.

Production outputs

The products covered under HS code 2519 are used as raw materials in a wide range of industries. Magnesite and fused magnesia find applications in the manufacture of 6815 non-metallic mineral products, such as refractory bricks, insulation materials, and cement. Dead-burned magnesia is primarily used in the production of 2320 refractory products, which are essential for high-temperature industrial processes. Magnesium oxide, in its pure form or as a component of other compounds, is utilized in the 2311 flat glass, 2013 inorganic chemical, and 2012 organic chemical industries.
