Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If parts specifically of turbojets
Even rough castings distinguish aircraft turbojet vs nonaircraft turbine parts.
If bulk castings not turbine-specific
General cast iron sanitary or machinery castings exclude gas turbine principal use.
If for semiconductor wafer processing machines
If end-use shifts to semiconductor equipment, Chapter 84 machines of 8479 may apply per notes.

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
• Request supplier certification of 'not advanced beyond cleaning/machining for location' per statistical notes
• Check for risers/gates fully removed; incomplete cleaning risks 8411.99.1080 reclassification
• Use ISF filings early due to high-value energy equipment scrutiny
