Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cut/manipulated into fittings
Welded steel tube fittings for general use classify under 7307, not raw tubes.
If of other alloy steel shapes (non-circular)
Non-circular welded profiles shift to 7306.60 regardless of use.
If imported with roasted mineral residues
Special provisions for steel tubes containing roasting residues classify differently.
