6813.81.00.10 - Articles for use in civil aircraft, with a basis of mineral substances

This HTS category, 6813.81.00.10, specifically covers friction material articles designed for use in civil aircraft. These articles are characterized by having a primary composition of mineral substances, excluding asbestos. The "civil aircraft" designation is a crucial differentiator, indicating that these friction materials are intended for use in aircraft operated for commercial, private, or non-military purposes. Examples include brake pads and linings specifically engineered to meet the rigorous performance and safety standards of aviation.

This classification is distinguished from its sibling, 6813.81.00.50, which encompasses "Other" friction materials not containing asbestos, but not specifically designated for civil aircraft use. The key difference lies in the intended application and the stringent requirements associated with aircraft components. While both categories deal with non-asbestos friction materials, 6813.81.00.10 targets a niche within the broader category, focusing solely on articles for civil aviation.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is precise, and any friction material article not meeting the criteria of being for civil aircraft and having a basis of mineral substances (not asbestos) would fall under a different HTS code, likely the sibling category 6813.81.00.50 or another relevant heading depending on its composition and intended use. The focus remains on the material composition and the specific end-use in civil aviation.
