About millstones, grindstones, grinding wheels, etc without frameworks, for grinding, sharpening, polishing, etc and parts thereof, natural stone, agglomerated natural or artificial abrasives or of ceramics

HS code 6804 covers a range of abrasive tools and equipment used for grinding, sharpening, polishing, and other surface finishing applications. These products are essential for a variety of industries, including construction, manufacturing, and mining, where they are used to shape, smooth, and refine materials. The global market for these products is driven by the ongoing demand for high-quality, durable, and efficient tools and equipment across diverse sectors.

Production process

The production of the items covered under HS code 6804 typically involves a combination of natural and synthetic materials. Natural stone, such as granite or sandstone, is often used as the base material, which is then shaped and bonded with abrasive grains, such as silicon carbide or aluminum oxide, to create the desired grinding or polishing surface. Alternatively, these abrasive materials can be combined with a ceramic or resin binder to form synthetic grinding wheels or discs. The final products are then subjected to various finishing processes, such as balancing, truing, and dressing, to ensure optimal performance and safety.

Production inputs

The main inputs required for the production of items under HS code 6804 include natural stone, such as 2506 Quartz and 2516 Granite, as well as synthetic abrasive materials like 2849 Silicon Carbide and 2818 Aluminum Oxide. Additionally, manufacturers require specialized machinery, such as grinding and polishing equipment, as well as binders, adhesives, and other materials to assemble the final products.

Production outputs

The products covered under HS code 6804 are primarily used as tools and equipment for various surface finishing and material processing applications. These include 8460 Machine-tools for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal or cermets, 8461 Machine-tools for planing, shaping, slotting, broaching, gear cutting, gear grinding or gear finishing, sawing, cutting-off and other machine-tools working by removing metal or cermets, and 8462 (Machine-tools (including presses) for working metal by forging, hammering or die-stamping; machine-tools (including presses) for working metal by bending, folding, straightening, flattening, shearing, punching or notching; presses for working metal or metal carbides, not specified above). The outputs of this industry are essential for a wide range of manufacturing and construction activities.
