About HS Code 680421
This HS code covers high-performance millstones, grindstones, grinding wheels, and similar abrasive tools made from agglomerated synthetic or natural diamond. These tools are at the forefront of precision grinding and cutting technology, essential for working with extremely hard materials such as ceramics, carbides, glass, stone, and advanced alloys. The diamond abrasive provides unparalleled hardness and cutting efficiency, making these tools indispensable in industries requiring high precision and material removal rates. Major importers are typically countries with advanced manufacturing sectors, including automotive, aerospace, electronics, and construction. Exporters are often nations with strong R&D capabilities in materials science and advanced manufacturing. Key considerations in trade include diamond concentration, bond type, and tool geometry, which dictate performance and application.
Products Under This Code
Diamond grinding wheels, diamond cutting discs, diamond polishing pads, diamond honing stones, diamond saw blades, diamond core bits, diamond files
Real World Examples
Norton Abrasives diamond wheels, Tyrolit diamond cutting discs, 3M Cubitron diamond abrasives, Bosch diamond saw blades
Common Misclassification
Easily confused with 680422 (other agglomerated abrasives) or 680423 (natural stone abrasives) if the diamond component is overlooked. The 'agglomerated synthetic or natural diamond' is the defining characteristic.
Products Classified Under 6804.21
Trade Overview
China, Germany, the USA, and Japan are major producers and exporters, with global manufacturing hubs being key importers.
