Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of alloy steel
Alloy steel seamless tubes shift to 7304.51 regardless of dimensions due to material composition.
If welded instead of seamless
Welded pipes of nonalloy steel fall under Chapter 73 heading 7306, even with similar dimensions.
If wall thickness 12.7 mm or greater
Thicker wall tubes in same OD range classified under different statistical breakouts within 7304.39.
