HS Code for Diamond millstones
View full HS code detailsDiamond millstones and grinding wheels are classified under HS code 6804.21. This heading covers millstones, grindstones, grinding wheels, and similar articles without frameworks, specifically those made of agglomerated synthetic or natural diamond. The classification is determined by the abrasive material that performs the work on the surface of the tool. In this case, the presence of diamond as the abrasive agent dictates the use of 6804.21. These articles are typically manufactured by bonding diamond grit with various agents such as resin, metal, or vitrified bonds. They are essential in industries requiring high-precision cutting, grinding, and polishing of extremely hard materials like stone, glass, ceramics, and certain alloys. It is important to note that this heading excludes tools that have a permanent framework or handle, as those are generally classified in Chapter 82 as tools or parts of tools.
