Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wall thickness under 12.7 mm
Same OD range but thinner walls shift to lighter casing subheading in the same chapter.
If welded rather than seamless
Welded steel pipes for oil/gas drilling fall under Chapter 73 heading for welded tubes, not seamless.
If made from alloy steel
Alloy steel composition (e.g., chrome-moly) changes from nonalloy steel classification.
