Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is submerged arc welded (SAW) longitudinally
Submerged arc welded pipes are classified separately under 7305.11.00 when the weld is longitudinal.
If the pipe is welded by a method other than submerged arc or longitudinal
Other welding methods for large-diameter circular pipes fall under this alternative.
If the external diameter is 406.4 mm or less
Smaller welded pipes of iron or steel are classified under heading 7306.

Import Tips & Compliance
• Ensure the pipe's external diameter exceeds 406.4 mm and that the weld is longitudinal, as this determines classification under 7305.31.00
• Have mill test certificates ready to confirm the alloy steel composition for the CBSA
• Verify whether anti-dumping or countervailing duties apply to the specific country of origin
