Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for spark-ignition reciprocating engines
Rotors for aircraft or other engines classify under 8407, not steam turbines.
If not specifically identified for steam turbines
Unspecified steel forgings or stampings default to Chapter 73 articles.
If designed for gas turbine derivations
Certain gas turbine parts share similarities but head under 8411.

Import Tips & Compliance
• Certify end-use for marine propulsion to support 8406 classification; general rotors risk 8483
• Ensure no balancing or profiling beyond sprue removal per ISO machining standards
• Avoid bulk packaging that suggests sets; ship as individual components
