Emery, natural corundum, natural garnet and other natural abrasives, whether or not heat-treated

HS code 251320 covers a range of natural abrasive materials, including emery, natural corundum, and natural garnet. These materials are widely used in various industries, from construction and manufacturing to jewelry and gemstone processing. They play a crucial role in shaping, polishing, and refining a diverse array of products, contributing to the overall efficiency and quality of industrial processes.

The production of natural abrasives under HS code 251320 typically involves the extraction, processing, and refinement of these materials from their natural sources. Emery, corundum, and garnet are mined from deposits around the world, and then undergo various stages of crushing, screening, and grading to produce the desired particle sizes and specifications. In some cases, the materials may also be subjected to heat treatment to enhance their abrasive properties.

The main inputs required for the production of natural abrasives under HS code 251320 include the raw mineral deposits, mining and processing equipment, and energy sources to power the various stages of production. Depending on the specific application, additional inputs such as specialized packaging or transportation infrastructure may also be necessary.

The primary outputs of the industry covered by HS code 251320 are the various grades and forms of natural abrasives, including emery, corundum, and garnet. These materials are then consumed by a wide range of industries, such as 282010 Aluminium oxide, 680610 Slag wool, rock wool and similar mineral wools, and 711590 Other articles of precious metal or of metal clad with precious metal, where they are used for tasks like polishing, grinding, and surface preparation.
