Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the insulating liner dominates as flexible plastic tubing
Primarily plastic conduit tubing shifts to Chapter 39 artificial gut/reservoir classification.
If for unlined galvanized steel threaded fittings
Base metal articles without insulation classify under Chapter 73 other steel products.
If assembled with electrical contacts or terminals
Fittings with integral electrical components become parts of connection apparatus in 8538.
