Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically for oil or gas pipeline use
Pipes not designated as line pipe for oil/gas pipelines are classified under other seamless alloy steel tubes.
If welded rather than seamless
Welded line pipes of alloy steel fall under Chapter 73 heading for welded tubes, not seamless.
If made of stainless steel alloy
Stainless steel variants are separated into their own subheading within the line pipe category.
