About dolomite, whether or not calcined or sintered; including dolomite roughly trimmed, or merely cut by sawing or otherwise into blocks or slabs of rectangular (including square) shape; dolomite ramming mix

HS code 2518 covers a range of dolomite products, a mineral that plays a crucial role in various industries. Dolomite is a type of sedimentary rock composed of calcium magnesium carbonate, and it is widely used as a raw material in construction, metallurgy, and chemical manufacturing. The dolomite industry is an essential component of the broader mining and mineral processing sector, contributing to the global economy through its diverse applications.

Production process

The production of dolomite products under HS code 2518 typically involves a series of extraction, processing, and refinement steps. Dolomite is primarily mined from natural deposits, either through open-pit or underground mining techniques. The extracted dolomite is then crushed, screened, and sorted to achieve the desired particle size and purity. Depending on the end-use application, the dolomite may undergo further processing, such as calcination (heating to high temperatures) or sintering (fusing the particles together).

Production inputs

The main inputs required for the dolomite industry under HS code 2518 include the raw dolomite mineral, which is the primary resource. Additionally, the industry relies on specialized mining and processing equipment, such as excavators, crushers, and kilns. Energy sources, such as electricity or fossil fuels, are also essential for powering the various stages of production. Labor, transportation, and logistics infrastructure are other significant inputs that enable the efficient extraction, processing, and distribution of dolomite products.

Production outputs

The dolomite products covered under HS code 2518 have a wide range of applications. The primary outputs include crushed or cut dolomite blocks, slabs, and powders. These dolomite materials are used as a flux in steel production 7201 Pig iron and spiegeleisen in pigs, blocks or other primary forms, as a filler in the production of 3824 Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries, and as a raw material in the manufacture of 2523 Cement. Dolomite is also utilized in the production of 3102 Mineral or chemical fertilizers, nitrogenous, 3105 Mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus and potassium; other fertilizers, and various other chemical products.
