6805.30.50.00 - Other

This HTS category, 6805.30.50.00, encompasses abrasive materials applied to a base that is not textile, paper, or paperboard. The "other materials" base is broad and can include a variety of substances, such as plastics, rubber, or composite materials. The key characteristic is the presence of abrasive particles adhered to a backing that falls outside the more specifically defined categories. These products are typically manufactured for polishing, grinding, or finishing surfaces.

This classification is distinct from its sibling category, 6805.30.10.00, which specifically covers articles wholly or partly coated with abrasives that are presented in pre-defined forms like sheets, strips, disks, belts, or sleeves. While both involve abrasive coatings on a base, 6805.30.50.00 captures those with non-standard backing materials or those not specifically shaped into the forms enumerated in the sibling category.

As this is a leaf node, there are no further subcategories. Therefore, classification into 6805.30.50.00 depends on identifying the specific "other material" used as the base and confirming that the product's primary function is abrasive, without fitting into more specific headings within Chapter 68 or other chapters. Examples might include abrasive-coated sponges or flexible abrasive pads made with synthetic resin binders and non-woven fabric backings, where the backing is not textile.
