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, fused magnesia, and magnesium oxide are all included under this code, reflecting their importance as key industrial inputs. These materials find widespread application in sectors such as construction, steel production, and chemical manufacturing, making them an integral part of the global economy.

Production process

The production of the goods covered by HS code 2519 typically involves a few key steps. Natural magnesium carbonate (magnesite) is extracted from mineral deposits and then processed through calcination, where it is heated to high temperatures to drive off carbon dioxide, leaving behind magnesium oxide. Fused magnesia is produced by melting magnesium oxide at extremely high temperatures, while dead-burned (sintered) magnesia is created by heating magnesium oxide to the point of partial fusion. Magnesium oxide, in its pure or impure form, can also be produced directly from magnesite or other magnesium-rich sources.

Production inputs

The main inputs required for the production of goods under HS code 2519 are magnesium-bearing raw materials, such as magnesite, dolomite, and seawater. Specialized high-temperature furnaces and kilns are also essential for the calcination, fusion, and sintering processes involved. Additionally, energy sources, such as natural gas or electricity, are needed to power the production facilities.

Production outputs

The outputs of the industries covered by HS code 2519 include a range of magnesium-based products, such as 2519 (Natural magnesium carbonate (magnesite)), 2519 Fused magnesia, 2519 (Dead-burned (sintered) magnesia), and 2519 Magnesium oxide, pure or not. These materials are then consumed by various downstream industries, including 6815 Articles of stone or of other mineral substances, 7201 Pig iron and spiegeleisen in pigs, blocks or other primary forms, and 2816 Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides, of strontium or barium.
