Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is submerged arc welded (SAW) longitudinally
Longitudinally submerged arc welded pipes are classified under 7305.11.00.
If the pipe is seamless rather than welded
Seamless pipes of circular cross-section are classified under heading 7304.
If the external diameter is 406.4 mm or less and of alloy steel
Smaller welded alloy steel pipes fall under heading 7306.
