Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy content below de minimis thresholds
Insufficient alloying elements classify as cold-drawn carbon steel tubing.
If hot-finished rather than cold-drawn
Finishing method determines specific statistical reporting within carbon steel.
If cut and threaded for fittings
Threaded pipe ends change classification from tubes to pipe fittings.
