Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If OD 114.3 mm to 285.8 mm
Smaller diameter casing (4.5-11.25 inches) uses the prior OD subheading even with identical wall and threading.
If used for structural line pipe rather than drilling
Same pipe specs but designated for pipeline transport classify under heading 7307 for line pipe.
If made from carbon steel, not alloy
Non-alloy steel versions of identical casing geometry fall under carbon steel casing provisions.
