Machined Steam Turbine Rotor for Industrial Power Generation
A precision-machined rotor designed for steam turbines used in industrial power plants, cleaned and machined solely to remove casting fins, gates, sprues, and risers. This allows precise location in finishing machinery without further advancement. It falls under HTS 8406.90.60.00 as a semi-finished part of steam turbines limited to basic post-casting cleanup.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for gas turbine use rather than steam
Gas turbine rotors classified under Chapter 84 heading 8411 for turbojets/turboprop/turbofan parts.
If further machined with grooves or keyways
More advanced rotors with functional features like balancing grooves fall under 8483 as finished machine parts.
If imported in rough cast state before any machining
Uncleaned cast iron/steel rotors are castings under Chapter 73, not turbine parts until cleaned/machined.

Import Tips & Compliance
• Verify machining does not exceed cleaning for fins/gates/sprues or location fixturing to avoid reclassification as finished parts under 8406.90.10
• Provide foundry certifications and machining logs proving limited processing to comply with HTS note restrictions
