Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not cast iron, e.g., aluminum or advanced processing
Non-cast-iron or further machined parts of turbojets are in broader parts categories.
If specifically for spark-ignition reciprocating engine parts
Similar housings for piston engines fall under Chapter 84 spark-ignition provisions, not gas turbines.
If retail packaged as replacement auto parts
Iron castings for vehicles packaged for retail shift to Chapter 73 vehicle-specific articles.
