Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If internally clad with corrosion alloy
Lined riser pipes for sour service classify under 7305.
If with buoyancy modules attached
Complete riser assemblies become drilling rig parts.
If imported installed on floating structures
Piping integral to oil platforms/rigs may classify as floating structures.
