8807.90.90.15 - For use by the Department of Defense or the United States Coast Guard

This HTS subcategory, 8807.90.90.15, specifically identifies parts and accessories designated for use by the Department of Defense (DoD) or the United States Coast Guard, when such parts are not specifically provided for elsewhere in heading 8807 and are intended for aircraft covered by headings 8801, 8802, or 8806. This classification is critical for distinguishing military or coast guard specific aircraft components from those intended for general civil aviation use.

Unlike its sibling category, 8807.90.90.30, which broadly covers "Other" parts of aircraft not otherwise specified, this designation hinges on the intended end-user. The crucial determining factor for classification under 8807.90.90.15 is the explicit and documented requirement that the part is to be incorporated into or used in conjunction with aircraft operated by the DoD or US Coast Guard. This often involves specialized materials, specifications, or certifications that differentiate them from civilian counterparts.

As a leaf node, this classification does not have further subdivisions. The scope is limited to the specific end-use by these governmental entities. Therefore, classification into this subcategory requires verification of the intended application and the procuring or operating authority. The general principle remains that parts for aircraft of headings 8801, 8802, or 8806, falling under the broad "other" classification of 8807.90, are routed to this specific code when exclusively designated for the Department of Defense or the United States Coast Guard.
