Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having threaded connections exceeding specified limits
Casing with significant threading classified differently from plain-end pipe.
If sold as tube fittings or couplings
Shorter lengths or specialized end fittings classify as fittings rather than casing pipe.
If cold-drawn/hardened construction
Specific manufacturing process (cold-drawn) moves to 7304.41 subheading.
