Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If integral to saw blade assembly
Parts directly incorporating saw blades classify as saw tool parts rather than vacuum compressor components.
If for liquid pumps in slicing coolant systems
Compressor housings for gas systems stay in 8414; liquid pump parts move to 8413.
If imported as rough castings
Unfinished cast iron products classify by material until machined to compressor housing specifications.
