Product classification
HS code for Abrasive grinding wheels: 6804.22
Millstones, grindstones, grinding wheels and the like, of other agglomerated abrasives or of ceramics.
Classification of abrasive grinding wheels under HS 6804.22
Abrasive grinding wheels are classified under HS code 680422. This code falls under Heading 6804, which encompasses millstones, grindstones, grinding wheels, and similar articles without frameworks, used for grinding, sharpening, polishing, trueing, or cutting. Subheading 680422 specifically identifies those made of agglomerated abrasives or ceramics. The classification logic relies on the fact that these wheels are produced by bonding abrasive grains (like corundum or silicon carbide) with a binder, such as vitrified ceramic, resin, or rubber. This distinguishes them from wheels made of natural stone (680410) or those using diamond abrasives (680421). The absence of a framework is a critical requirement; if the wheel is permanently mounted on a machine-specific frame or axle, the classification might shift, though most standard replaceable grinding wheels remain within 680422. These items are essential in precision engineering, tool sharpening, and industrial manufacturing processes.

Codes often confused with 6804.22
Common mistake. The most frequent misclassification occurs with HS code 680421, which is specifically for wheels made of synthetic or natural diamond. Using 680422 for diamond wheels is a common compliance error. Another area of confusion involves HS code 8207, which covers interchangeable tools for hand tools or machine tools. While 8207 includes many cutting and drilling tools, heading 6804 is more specific for articles made of agglomerated abrasives used for grinding. Furthermore, small mounted points or stones with shanks are sometimes incorrectly classified under 680422 when they should be evaluated against the specific dimensions and shanks defined in other subheadings or headings depending on their primary function.
Top exporters and importers of HS 680422 (the code used for abrasive grinding wheels), 2025

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).
