8807.30.00.15 - For use by the Department of Defense or the United States Coast Guard

This HTS subcategory, 8807.30.00.15, specifically classifies parts designed for use in civil aircraft that are *not* for use by the Department of Defense or the United States Coast Guard. This designation is crucial for determining the applicable duty rates and import regulations, as it carves out a distinct category for components intended for general aviation, commercial airlines, and other non-military or non-coast guard aviation applications. The parts falling under this code are those that integrate into the structure, propulsion, or operational systems of airplanes, helicopters, or unmanned aircraft.

This classification is distinguished from its sibling category, 8807.30.00.30 ("Other"), by its explicit restriction to parts for civil aircraft and the exclusion of those designated for military or coast guard use. While both categories fall under "Other parts of airplanes, helicopters or unmanned aircraft," the "For use by the Department of Defense or the United States Coast Guard" designation at 8807.30.00.15 provides a specific exclusion for components intended for government aviation entities. Therefore, if a part is intended for use in a commercial airliner, it would fall under 8807.30.00.15, whereas a part for a military transport aircraft would be classified differently.

As this is a leaf node, there are no further subcategories. Classification at this level is determined by the intended end-user and the civil application of the aircraft into which the part will be incorporated. Importers must ensure they have accurate documentation confirming the civil aviation purpose of the parts to correctly apply this HTS code.
