9014.90.20.80 - Other

This HTS subheading, 9014.90.20.80, covers "Other" parts and accessories for direction finding compasses and other navigational instruments and appliances, specifically those not classifiable under the sibling category of parts for use in civil aircraft. This designation is a residual category, intended to capture any remaining parts and accessories that fall within the scope of Chapter 90 but do not fit into more specific classifications. Examples of items that might be classified here include repair components for non-aviation compasses (such as handheld, marine, or automotive compasses), spare parts for sextants, gyroscopic navigators, or other precision navigational apparatus not explicitly designed or designated for civil aircraft use.

The key differentiator for this subheading lies in its exclusion of parts specifically intended for civil aircraft applications, which are separately classified under subheading 9014.90.20.40. While both subheadings pertain to parts and accessories of navigational instruments, the intended application dictates the classification. Therefore, when classifying a part, it is crucial to ascertain whether its primary design and intended use is for integration into an aircraft navigation system or for a broader range of navigational applications.

As this subheading represents a terminal node within the HTS structure, there are no further subcategories. Classification within 9014.90.20.80 depends on the specific part or accessory's nature and its relationship to the broader category of navigational instruments and appliances, excluding those designated for civil aviation.
