Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wall thickness less than 12.7 mm
Thinner-walled casing stays in the same casing category but moves to the subheading for walls under 12.7 mm.
If welded instead of seamless
Welded casing, tubing, or drill pipe for oil/gas drilling falls under Chapter 73 heading 7306 for other tubes/pipes.
If made of alloy steel
Alloy steel versions (with specific alloying elements exceeding nonalloy limits) classify under 7304.59 for alloy steel casing.
