9014.20.80.40 - For use in civil aircraft

This HTS classification, 9014.20.80.40, specifically covers navigational instruments and appliances intended for use in civil aircraft. This includes a broad range of devices essential for aviation navigation, such as gyroscopic instruments, air data computers, attitude indicators, and other specialized equipment designed to aid pilots in determining position, course, and altitude within the civil aviation sector. The key differentiator for this category is its explicit designation for use in civil aircraft, distinguishing it from similar instruments that might be designed for military aviation or other transportation modes.

While the immediate sibling category, 9014.20.80.80, also falls under "Other" navigational instruments and appliances, this distinction typically hinges on specific end-use or, in some cases, less common or specialized applications not exclusively tied to civil aircraft. This specific code ensures that instruments designed and manufactured for the rigorous requirements and certifications of civil aviation are correctly identified.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, the classification relies on accurately identifying instruments that are functionally and contextually designed and marketed for civil aircraft operations, differentiating them from general-purpose navigation equipment or those solely intended for other specialized fields.
