Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If parts of semiconductor manufacturing machines broadly
If not pump-specific, may fall under general semi machine parts.
If classified as control boards
Standalone controller panels go to Chapter 85 boards.
If for vacuum gauge integration in testing
Process control instruments classify in Chapter 90.
