Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for structural/non-drilling use
Pipes not specifically for oil/gas drilling classified as other welded/structural under 7306.
If other casing not fitting diameter specs
Catch-all for non-specified diameter seamless casing/tubing.
If galvanized for corrosion protection
Surface treatment like galvanizing moves to coated pipes in 7306.50.
