Last updated: August 2026 dataAirframe structural components, avionics, landing gear assemblies, and other aircraft parts not elsewhere classified form a broad and commercially active import category that feeds both MRO (maintenance, repair, and overhaul) operations and new-aircraft production. FAA airworthiness traceability requirements apply regardless of whether parts are destined for installation or inventory, and many items also require export-license review under EAR or ITAR before they can be re-exported. The 'NESOI' designation signals that classification into this code requires ruling out all more specific six-digit alternatives first.

'Not elsewhere specified or included' means this code is a residual catch-all: a part should be classified here only after confirming it does not fit a more specific heading such as aircraft engines (336412) or guided missile parts (336419). Misuse of residual codes is a common audit finding and can trigger CBP penalty proceedings.
The formal entry process is the same, but MRO shipments often involve goods that were previously exported for repair and are returning to the US. In those cases, importers may be able to claim duty relief under HTS Chapter 98 provisions for American goods returned, provided the parts were originally of US origin and the repair was performed abroad. Documentation of the original export is essential to support the claim.
