Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specific turbopropeller casings or gearboxes
Named parts like casings classify separately from complete engines.
If for unmanned aircraft systems (UAS)
Spacecraft or UAS engines may shift to other aircraft categories.
If industrial ground-based applications
Non-aircraft gas turbines of similar power use different subheadings.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Include type certificate data sheet from FAA to substantiate aircraft turbine classification
• Separate gearbox and propeller components if imported disassembled to avoid parts headings
• Comply with BIS export controls; file EEI for shipments over $2,500
