Classification of polishing stones under HS 6804.30
Polishing stones are classified under HS code 6804.30. This heading covers hand sharpening or polishing stones made of natural stone, agglomerated natural or artificial abrasives, or ceramics. These items are distinct because they are designed for manual use rather than being mounted on a machine. The classification includes stones used for honing, sharpening, or polishing surfaces by hand. The materials used are typically bonded abrasives like silicon carbide or aluminum oxide, or natural stones like Arkansas stone. The code 6804.30 specifically excludes items that are essentially abrasive powder coated onto paper or fabric (which fall under 6805) and also excludes millstones or grinding wheels designed for mechanical use.

Codes often confused with 6804.30
Common mistake. A frequent error is classifying these under 6804.22, which is for grinding wheels and similar articles intended for use on machines. The distinction lies in whether the item is a hand tool or a machine component. Another misclassification occurs with 6805.10, which covers abrasive cloth; polishing stones are solid blocks, not flexible coated abrasives. Additionally, pumice stones used for cosmetic purposes are often incorrectly placed here but should be in 3304.

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).
