6813.20.00.10 - Articles for use in civil aircraft

This HTS classification, 6813.20.00.10, specifically covers friction materials designed for use in civil aircraft. These friction articles, whether in the form of sheets, rolls, strips, segments, discs, washers, or pads, are not mounted and are intended for applications such as brakes or clutches. Crucially, the primary distinguishing characteristic of this category is that the friction material has a basis of asbestos or other mineral substances or cellulose, and it is explicitly designated for incorporation into civil aircraft.

The distinction from sibling category 6813.20.00.15, "Other," is vital for accurate classification. While both categories fall under friction materials containing asbestos and intended for brakes or clutches, 6813.20.00.10 is reserved exclusively for those articles destined for civil aircraft. Any other friction material fitting the general description but not intended for civil aircraft would be classified under the broader "Other" category.

As this is a leaf node, there are no further subcategories. The classification is complete once the article meets the criteria of being a friction material (sheets, rolls, etc., for brakes/clutches), containing asbestos or other mineral substances/cellulose, and specifically intended for use in civil aircraft. This strict specification ensures that components critical to aviation safety and regulation are correctly identified and accounted for within the customs framework.
