Industrial diamonds, unworked or simply sawn, cleaved or bruted; pumice stone; emery; natural corundum, natural garnet and other natural abrasives

cpc code 1632 covers a diverse range of natural abrasive materials, including industrial diamonds, pumice stone, emery, and natural corundum and garnet. These materials play a crucial role in various manufacturing and processing industries, serving as essential inputs for cutting, grinding, polishing, and other abrasive applications. The global demand for these natural abrasives is driven by their unique physical properties, such as hardness, durability, and ability to remove material efficiently, making them indispensable in a wide range of industrial sectors.

The production of the materials covered under cpc code 1632 typically involves extraction, sorting, and processing. Industrial diamonds are mined from kimberlite and lamproite deposits, then sorted, graded, and sometimes cut or polished to meet specific requirements. Pumice stone is quarried from volcanic deposits and may undergo further crushing or sizing to produce the desired grades. Emery, natural corundum, and natural garnet are also mined from their respective geological sources and may undergo various processing steps, such as crushing, screening, and beneficiation, to refine the product and remove impurities.

The main inputs required for the production of the materials covered under cpc code 1632 include the raw geological deposits, mining and extraction equipment, and processing machinery. Depending on the specific material, additional inputs such as cutting or polishing tools, sorting and grading equipment, and packaging materials may be necessary. Energy sources, such as electricity or fuel, are also essential for powering the various production and processing stages.

The outputs of the industries covered under cpc code 1632 are primarily the various types of natural abrasive materials, including industrial diamonds, pumice stone, emery, natural corundum, and natural garnet. These materials are then consumed by a wide range of industries, such as 1622 Construction materials, 1711 Manufacture of pulp, paper and paperboard, 2599 Manufacture of other fabricated metal products n.e.c., and 2822 Manufacture of lifting and handling equipment, where they are used for cutting, grinding, polishing, and other abrasive applications.
