This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If round billet for extrusion
Billets for pipe-making are semi-finished, not primary ingots.
If already extruded to tube
Finished seamless pipes of alloy steel classify under Chapter 73.
If tool steel composition
Specific C/Cr ratios per note (e) require tool steel headings.
