HS Code for Natural stone grinding wheels

Natural stone grinding wheels are classified under HS code 6804.23. This classification is determined by the material composition and the intended function of the article as defined in the Harmonized System. Heading 6804 encompasses millstones, grindstones, grinding wheels, and similar items without frameworks, used for grinding, sharpening, polishing, trueing, or cutting. Subheading 6804.23 specifically isolates those products made of natural stone. Unlike synthetic alternatives, these wheels are shaped directly from naturally occurring stone blocks, such as sandstone, granite, or lava stone. The classification follows General Interpretative Rule (GRI) 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since the product is a grinding wheel made of natural stone, it fits precisely into the description provided by 6804.23. The absence of a framework is a key requirement for this heading; if the stone were mounted on a complex mechanical frame, it might be classified as part of a machine in Chapter 84. However, for the stone component itself or simple wheels used for manual or mechanical sharpening, 6804.23 remains the primary code. The material must be natural stone and not agglomerated natural stone powder, which would fall under a different subheading.

Products Included

Common Misclassification

Natural stone grinding wheels are frequently confused with HS code 6804.22, which covers grinding wheels made of agglomerated synthetic or natural abrasives. The distinction lies in whether the wheel is cut from a single block of natural stone (6804.23) or formed by bonding abrasive grains together with a binder (6804.22). Additionally, they may be confused with HS code 6805, which covers natural or artificial abrasive powder or grain on a base of textile material, paper, or paperboard. 6805 is for flexible abrasives, whereas 6804 is for rigid wheels and stones.
