HS Code for Diamond grinding wheels

6804.21 Millstones, grindstones, grinding wheels and the like; of agglomerated synthetic or natural diamond
View full HS code details

Diamond grinding wheels are classified under HS code 6804.21. This code is designated for millstones, grindstones, grinding wheels, and similar articles without frameworks, used for grinding, sharpening, polishing, trueing, or cutting, made of agglomerated synthetic or natural diamond. While diamonds themselves are categorized in Chapter 71, once they are bonded or agglomerated into a specific tool shape like a wheel, they move to Chapter 68, which covers articles of stone, plaster, cement, asbestos, mica, or similar materials. The sub-heading 6804.21 specifically identifies those where the abrasive part consists of diamond. This classification is based on the function of the article as an abrasive tool and its material composition. The wheels may be bonded with resin, metal, or vitrified materials, but as long as the active abrasive component is diamond, 6804.21 remains the correct classification. This includes wheels used for precision grinding in the automotive, aerospace, and tool-making industries.

Products Included

  • Resin-bonded diamond grinding wheels
  • Metal-bonded diamond wheels
  • Vitrified diamond wheels
  • Diamond honing stones
  • Diamond cutting discs (without frameworks)

Common Misclassification

A common misclassification occurs with HS code 8207, which covers interchangeable tools for hand tools or machine tools. However, 6804 specifically excludes tools with a working part of diamond if they are not agglomerated wheels or stones. Another error is using 7105, which is for the diamond dust itself before it has been manufactured into a wheel. Furthermore, if the wheel has a permanent framework or is part of a specific machine, it might be confused with Chapter 84 machinery parts.
