HS code for Whetstones: 6804.30

Stones, hand sharpening or polishing stones, of natural stone, agglomerated natural or artificial abrasives or ceramics, with or without parts of other materials.

Classification of whetstones under HS 6804.30

The classification of whetstones under HS code 6804.30 is determined by the General Rules for the Interpretation (GRI) of the Harmonized System. Specifically, Chapter 68 encompasses articles of stone, plaster, cement, or similar materials. Heading 6804 is dedicated to millstones, grindstones, grinding wheels, and similar articles, without frameworks, for grinding, sharpening, polishing, trueing, or cutting. Subheading 6804.30 specifically isolates hand sharpening or polishing stones. These items are characterized by their use in manual sharpening processes, where the stone is held in the hand or the tool is manually drawn across the stone. The material composition can vary from natural stone to agglomerated natural or artificial abrasives, or even ceramics. The classification remains consistent regardless of whether the stone is mounted on a simple base or has parts of other materials, provided it remains a hand-operated sharpening tool. The technical distinction is that these stones are not power-driven and are intended for manual finishing of edges on tools, knives, or other implements.

Codes often confused with 6804.30

Common mistake. Whetstones are frequently misclassified under HS code 6805.10, which covers natural or artificial abrasive powder or grain on a base of woven textile fabric. While both involve abrasives, 6805 refers to flexible coated abrasives like sandpaper, whereas 6804 refers to rigid stones. Another common error is using 8205.59, which covers other hand tools. However, because 6804 specifically names sharpening stones, GRI 1 dictates that the more specific heading takes precedence over a general tool category.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
