Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of steel rather than cast iron
Steel gas turbine parts in rough condition classify separately from cast iron provisions.
If for general industrial fans or blowers
Cast iron scrolls not dedicated to gas turbines go to Chapter 73 machinery castings.
If parts of steam turbines instead
Similar castings for steam turbine inlets fall under 8406, differentiated by engine type.

Import Tips & Compliance
• Provide engineering drawings showing minimal machining to qualify for cast-iron rough part rate
• Avoid common pitfall of over-machining in supplier country; specify 'rough casting only' in POs
• Pair with gas turbine invoice line to establish principal use for tariff purposes
