Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having wall thickness of 12.7 mm or more
Heavy wall casing for high-pressure applications exceeds thin-wall specification.
If imported in continuous lengths >18m without couplings
Uncoupled welded line pipe may classify differently from standard API casing.
If fitted with welded fittings for threading
Casing with attached fittings or connections becomes tube/pipe fittings.

Import Tips & Compliance
• Submit hydrostatic test reports showing pressure ratings suitable for oil/gas service
• Document plain end or threaded configuration clearly, as accessories may affect classification
• Check for anti-dumping duties on Chinese-origin casing; provide country of melt and manufacture
