Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electric resistance welded (ERW)
ERW line pipes use a different welding process, classified under 7304 for seamless-like properties.
If imported in coils or not fully tubular
Welded tubes other than line pipe or casing, over 406.4 mm, go to 7306.19 if not pipeline-specific.
If over 609.6 mm diameter
This subheading caps at 609.6 mm; larger pipes have separate provisions.

Import Tips & Compliance
• Ensure supplier provides dimensional certificates confirming external diameter stays within 406.4-609.6 mm
• For bulk shipments, segregate by grade to prevent mixing with alloy steel lots triggering higher duties
