8464.20.01.20 - Other

This HTS classification, 8464.20.01.20, specifically covers "Other" grinding or polishing machines used for working stone, ceramics, concrete, asbestos-cement, or similar mineral materials, as well as for the cold working of glass. It encompasses a broad range of machinery designed for surface finishing operations on these materials, where the primary function is to alter the surface by abrasive action, smoothing, or imparting a shine.

This category is distinct from its sibling, 8464.20.01.10, which is exclusively reserved for glass-working machines. While both deal with grinding and polishing, 8464.20.01.20 is broader, encompassing a wider array of mineral-based materials beyond just glass. Therefore, if a machine is intended for working stone or ceramics, even if it can also work glass, it would fall under this "Other" classification.

As this is a leaf node, there are no further subcategories. The classification is determined by the material being worked and the primary function of grinding or polishing, differentiating it from other machine tools for mineral materials that might involve cutting, drilling, or shaping without a primary focus on surface finishing. Examples include machines for polishing granite countertops, grinding concrete floors, or shaping ceramic tiles through abrasive action.
