Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in non-semiconductor vacuum pumps
Compressor parts for general air/vacuum pumps (not dedicated to semiconductor processing) classify under the parent pump heading.
If classified as part of complete semiconductor machine
Parts of unclassified semiconductor manufacturing machines fall under 8479, but isolated compressor housings remain in Chapter 84.
If imported as unfinished aluminum castings
Unmachined aluminum castings are classified by material rather than function until they become identifiable compressor parts.
