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

HS code 2518 covers dolomite, a type of sedimentary rock composed primarily of the mineral dolomite. Dolomite is a versatile material with a wide range of industrial applications, making it an important commodity in the global economy. This code encompasses dolomite in various forms, including calcined, sintered, and roughly trimmed or cut into blocks or slabs.

Production process

The production of dolomite typically involves mining the raw material from dolomite deposits. The extracted dolomite may then undergo various processing steps, such as crushing, screening, and sorting, to produce the desired size and purity. Depending on the intended use, the dolomite may also be subjected to calcination or sintering, which involves heating the material to high temperatures to alter its chemical and physical properties.

Production inputs

The primary input for the dolomite industry is the raw dolomite rock, which is extracted from natural deposits. Additionally, the production process may require various types of machinery and equipment, such as mining equipment, crushers, and kilns for calcination or sintering. Energy sources, such as electricity or fossil fuels, are also essential inputs for the processing and manufacturing of dolomite products.

Production outputs

The main outputs of the dolomite industry include various forms of processed dolomite, such as crushed dolomite, dolomite powder, and dolomite blocks or slabs. These dolomite products find applications in a wide range of industries, including 2523 Quicklime, slaked lime and hydraulic lime, 6801 (Setts, curbstones and flagstones, of natural stone (except slate)), and 6810 (Building or monument stone, worked, and articles thereof, other than goods of heading 6801; mosaic cubes and the like, of natural stone (including slate), whether or not on a backing; artificially colored granules, chippings and powder, of natural stone (including slate)).
