Last updated: July 2026 dataGrinding wheels and similar tools bonded with synthetic resins (6804221000) or other agglomerated abrasives and ceramics (6804224000, 6804226000) are precision-engineered consumables central to metalworking, aerospace component finishing, and automotive manufacturing. The US schedule distinguishes resin-bonded wheels from ceramic-bonded and other agglomerated types, a split that affects both classification and duty treatment. Austria leads US supply under this heading, followed by China and Germany — a sourcing mix that means importers should monitor Section 301 exposure on Chinese-origin wheels while evaluating European alternatives. Correct classification hinges on the bonding matrix and intended abrasive application, making product specification documentation essential at entry.
