Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as integral sensor components rather than complete mechanism
Individual parts classify separately from assembled auxiliary machinery in the same heading.
If when functioning primarily as industrial sensors independent of textile stop action
Measuring/evaluating instruments classify in 9031 if having individual functions beyond simple stopping.
If for the electrical control boards within the stop motion
Control panels/boards for electric machinery shift to Chapter 85 if not textile-specific.
