Last updated: August 2026 dataAbrasive finishing machine tools for deburring, polishing, and surface conditioning of metal and sintered carbide — not classifiable as grinding, honing, or lapping machines — serve a broad range of end uses from automotive body panels to medical device components. Germany and France lead US imports in this residual category, which also draws supply from China. The US schedule provides nine 10-digit lines segmented by NC status, condition, and value threshold, mirroring the structure used for honing and lapping machines. Because this heading is explicitly 'not elsewhere specified,' importers must first confirm the machine does not fit a more specific abrasive-finishing heading before classifying here.

Machines designed primarily for deburring sharp edges, vibratory finishing bowls, belt-finishing machines for surface conditioning, and robotic polishing cells for metal parts are typical examples. The key is that these machines are not designed to achieve the dimensional accuracy or geometric correction that defines grinding (846012–846029) or honing/lapping (846040). If a machine's primary function is cosmetic or edge-quality finishing rather than dimensional stock removal, 846090 is the appropriate heading.
When a machine and its functional attachment are imported together as a complete unit, they are generally classified as a whole based on the principal function of the combined system. If the deburring function is primary, the entire unit would be classified under 846090. If the attachment is sold separately as a spare or accessory, it may be classified independently. A licensed customs broker should be consulted to confirm the appropriate treatment based on the specific invoice and technical documentation.
