6813.20.00.25 - Other

This HTS code, 6813.20.00.25, classifies "Other" friction materials and articles thereof, not mounted, which are specifically designed for use in brakes, clutches, or similar mechanisms. These articles are characterized by their composition, which includes asbestos, other mineral substances, or cellulose, and may also incorporate textile or other materials. This designation applies to items that do not fall under more specific subheadings within the broader category of friction materials.

The primary distinction for this category lies in its exclusion from more narrowly defined applications. While sibling category 6813.20.00.20 specifically addresses articles intended for use in civil aircraft, this code encompasses all other non-mounted friction materials with the specified mineral or cellulose base that are not designated for aircraft. The "Other" designation signifies a residual category for articles not otherwise specified at this level of detail, provided they meet the general criteria of being friction material, containing asbestos or other mineral substances or cellulose, and are not mounted.

As this is a leaf node, there are no further subcategories. Therefore, classification within 6813.20.00.25 relies on a careful assessment of the material composition and intended application, ensuring that the item is a friction material, not mounted, and not specifically covered by other, more precise HTS codes within the 6813 heading, particularly those for civil aircraft applications. Examples could include general automotive brake pads or clutch facings not intended for aviation use.
