Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of steel rather than cast iron
Material change from cast iron excludes it from the 8411.91.10 subheading.
If assembled with vanes into complete stator assembly
Assembled gas turbine components classify separately from rough cast parts.
If for stationary industrial gas turbines
Non-aircraft turbine applications fall under general cast iron articles in Chapter 73.

Import Tips & Compliance
• Include foundry test reports showing only permitted machining to prevent duty reassessment
• Label clearly as 'aircraft turbine part' with OEM part number for CBP verification
• Avoid bulk packaging that suggests industrial use, which could trigger alternative classification
