8464.90.01.20 - Other

This HTS category, 8464.90.01.20, encompasses machinery designed for working mineral materials other than glass, specifically those used for stone, ceramics, concrete, or asbestos-cement. These machines are intended for operations like cutting, grinding, polishing, drilling, or shaping these hard mineral substances. The key defining characteristic is the material being worked, which excludes glass, and the mechanical nature of the processing.

This classification is distinct from its sibling, 8464.90.01.10, which specifically covers glass-working machines. While both fall under the broader category of machinery for working mineral materials, the focus on glass in the sibling category creates a clear demarcation. Therefore, any machine primarily designed for processing materials such as granite, marble, tile, brick, or cementitious composites would fall under this "Other" designation, provided it is not a glass-working apparatus.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Classification under 8464.90.01.20 relies on the definitive identification of the material being processed and the machine's function. If a machine can work multiple types of materials, its classification will generally be determined by the material that is the primary focus of its design and intended use, or by the most specific material if the machine is equally capable with several.
