Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pipe is seamless rather than welded
Seamless line pipe of iron or steel falls under heading 7304, which covers seamless tubes and pipes.
If the external diameter is 406.4 mm or less
Smaller-diameter welded line pipe is classified under heading 7306, which covers other tubes and pipes with smaller dimensions.
If the pipe is longitudinally submerged arc welded
Longitudinally welded line pipe is specifically provided for under subheading 7305.11, which is more specific than the 'other' category.
