Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not stainless steel
Welded iron/steel pipes (non-stainless) with thick walls go to 7306.30.
If as parts of chemical machinery
End-use in reactors or machinery may reclassify to Chapter 84/85 parts.
If non-circular cross-section
Welded profiles of other shapes (not circular) fall under 7306.90.
