6813.89.00 - Other

This HTS category, 6813.89.00, encompasses friction materials and their articles, not mounted, which are used for brakes, clutches, or similar applications. The defining characteristic of this classification is that these friction materials are not asbestos-based and are not specifically brake linings or pads. They are composed of other mineral substances or cellulose, and may incorporate textile or other materials to achieve desired friction properties.

Distinguishing this category from its sibling, 6813.81.00, is crucial. While 6813.81.00 exclusively covers brake linings and pads, this code (6813.89.00) applies to a broader range of friction articles that, while fulfilling a similar function, are not explicitly designated as brake linings or pads. This could include clutch facings, other types of friction segments, or specially shaped friction components for various industrial or automotive uses, provided they meet the material composition requirements and are not asbestos-containing.

Within this "Other" designation, further subdivisions exist to refine classification. The subcategory 6813.89.00.10 specifically addresses articles intended for use in civil aircraft, further specifying that their basis must be mineral substances. The remaining items falling under this general classification, but not meeting the specific criteria for aircraft use, are directed to the 6813.89.00.50 subcategory. This hierarchical structure allows for precise identification based on end-use and material composition beyond the initial broad categorization.
