Instruments & Appliances for Aeronautical or Space Navigation (Excluding Compasses)

To claim Civil Aircraft Agreement treatment, the importer typically must provide a signed end-use certificate or equivalent documentation confirming the article is for incorporation into or use on a civil aircraft. CBP may also require the aircraft's registration or a manufacturer's declaration. The claim is made at entry on the CBP Form 7501 by citing the appropriate special program indicator.

When a physical instrument or appliance performs the navigation function and software is merely an enabling component, classification remains under 9014.20. However, if the article is essentially a general-purpose computer running navigation software with no dedicated navigation hardware, it may fall outside Chapter 90 entirely. CBP's functional-unit and essential-character analysis governs; a binding ruling is advisable for hybrid hardware-software navigation products.
