HS Code for Abrasive grinding wheels

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.

Products Included

• Vitrified bonded grinding wheels
• Resinoid bonded snagging wheels
• Ceramic-bonded abrasive wheels
• Bench grinder wheels for metal sharpening
• Reinforced cutting-off wheels (non-diamond)

Common Misclassification

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.

FAQ

What is the HS code for grinding wheels?

The standard HS code for grinding wheels made of agglomerated abrasives (other than diamond) or ceramics is 680422.

Are diamond cutting wheels classified here?

No, diamond cutting wheels are classified under HS code 680421 because they utilize precious or semi-precious abrasive materials.
