Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If automotive castings
Cast iron castings for motor vehicles separate from stationary turbine bases.
If aircraft gas turbine parts
All aircraft turbine castings, even rough, classify distinctly from nonaircraft.
If parts of semiconductor processing machines
Bases for wafer fab equipment using gas turbines shift per Chapter 84 statistical notes.

Import Tips & Compliance
• Oversize shipments require ACE eManifest; coordinate port capabilities for massive castings
• Verify no internal webbing machined—pure rough exterior qualifies
• Section 301 exclusions may apply; check USTR lists for turbine castings
