HS Code 6804.22 – Millstones, grindstones, grinding wheels and the like; of other agglomerated abrasives or of ceramics

HS code 6804.22 is the 6-digit subheading for millstones, grindstones, grinding wheels and the like, of other agglomerated abrasives or of ceramics. It is used for aluminum oxide grinding wheels, silicon carbide grinding wheels, ceramic abrasive discs, vitrified grinding wheels and resinoid grinding wheels.

What HS 6804.22 covers

This category encompasses a vast range of millstones, grindstones, grinding wheels, and similar tools made from other agglomerated abrasives (e.g., aluminum oxide, silicon carbide) or ceramics. These are the workhorses of industrial grinding and finishing, used extensively across various manufacturing sectors for shaping, sharpening, deburring, and finishing metals, wood, plastics, and composites. Their versatility comes from the wide array of abrasive types, grit sizes, and bonding agents available, allowing for tailored solutions for different materials and desired finishes. Major importers are countries with robust industrial bases, including automotive, metalworking, woodworking, and general manufacturing. Exporters are typically nations with strong chemical and materials industries, capable of producing high-quality synthetic abrasives and ceramic bonds. Trade is driven by industrial production levels and technological advancements in abrasive materials.

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).
