8807.10.00.15 - For use by the Department of Defense or the United States Coast Guard

This HTS category, 8807.10.00.15, specifically covers propellers, rotors, and parts thereof that are designated for use by the Department of Defense or the United States Coast Guard. This distinction is crucial, as it separates these components from those intended for civilian aviation applications. The classification hinges on the intended end-user, ensuring that military and Coast Guard aviation equipment is correctly identified for customs purposes.

Distinguishing this category from its sibling, 8807.10.00.30 (Other), is primarily based on the stated end-user. While both cover propellers, rotors, and parts thereof, the "Other" category would encompass items not specifically designated for the Department of Defense or Coast Guard. This implies that items for general commercial aviation or private aircraft would fall under the "Other" sibling.

As this is a leaf node, there are no further subcategories. The classification is complete at this level, focusing solely on the specific end-use by the Department of Defense or the United States Coast Guard for propellers, rotors, and their associated parts.
