Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not hand-operated, e.g., solenoid actuated
Automatically controlled valves for semiconductor processing fall under other valves provisions, excluding hand-operated and check types.
If for semiconductor manufacturing equipment specifically
Parts of valves dedicated to semiconductor wafer fab equipment may classify under specialized statistical suffixes.
If considered pipe fittings rather than valve parts
Tube or pipe fittings of steel without valve function shift to Chapter 73 headings.
