Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If air/liquid pumps
Hubs principally for pumps classify separately from turbines.
If open-die forged castings
Products combining casting/forging go to Chapter 73 provisions.
If semiconductor testing machines
Turbine-derived parts for chip testing equipment per statistical notes.

Import Tips & Compliance
• Hub bore must remain rough; any finish machining shifts classification
• Balance set documentation if imported with impellers
• ITAR check if military turbine application suspected
