Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used as oil well tubing
Tubing for insertion into wells is classified under 7306.30 based on specific oilfield drilling application.
If welded rather than seamless
Welded line pipes (electric resistance or other) fall under 7304.29 provisions.
If cut to short lengths for fittings
Tube or pipe fittings of alloy steel are under heading 7307 when shaped for connections.
