6804.23.00.00 - Of natural stone

This HTS category, 6804.23.00.00, specifically covers millstones, grindstones, grinding wheels, and similar articles intended for grinding, sharpening, polishing, trueing, or cutting. It also includes hand sharpening or polishing stones and their parts, all of which are exclusively manufactured from natural stone. The "natural stone" component is the defining characteristic for classification within this heading.

Unlike its sibling categories, this classification does not include articles made from agglomerated synthetic or natural diamond (6804.21.00) or those composed of other agglomerated abrasives or ceramics (6804.22). The critical distinction lies in the primary material: only articles fashioned entirely from stone quarried from the earth, such as granite, marble, or sandstone, fall under this specific sub-heading.

As a leaf node, 6804.23.00.00 does not have further subdivisions. Therefore, classification into this category relies solely on confirming that the article in question is designed for abrasive purposes and is made entirely of natural stone, with no other primary constituent materials present. Examples include sharpening stones fashioned from slate or basalt, and rough-hewn millstones made from hard igneous rocks.
