Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel version
N80 with alloy elements like chromium moves to alloy steel casing in 7304.29.
If sold as individual components
Uncoupled tubing or separate couplings classify under different subheadings for other steel types.
If fully assembled into drilling rigs
If imported as part of a complete drilling machine, it becomes a parts classification in Chapter 84.
