Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of alloy steel rather than nonalloy
Alloy steel variants (e.g., with chromium >1.5%) shift to 7304.59 headings based on material composition.
If welded instead of seamless
Welded line pipes for oil/gas pipelines fall under Chapter 73 heading 7306 for welded tubes.
If outside diameter 219.1 mm or larger
Larger OD seamless line pipes are classified in separate statistical suffixes within the same subheading.
