Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for gas turbine use
Rotor designed for gas rather than steam turbines falls under gas turbine parts heading.
If imported as part of a complete pump assembly
Gears and rotors for pumps are classified separately from turbine rotors.
If unfinished or semi-machined
Only fully finished rotors for final assembly qualify; others go to general parts.

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
• Verify rotor dimensions and balance certification to meet ASME standards for steam turbine parts
• Include detailed engineering drawings and material specs (e.g
• high-strength alloys) in documentation
• Avoid misclassification as unfinished by ensuring all machining and balancing is complete
