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 free-cutting alloy steel
Steels with added lead/sulfur for machinability classify under 7228.40 instead of tool steel.
If non-alloy steel composition
Lacking alloy elements for tool steel note, it falls to nonalloy cold-finished bars in Chapter 72.
If angles, shapes, or sections
Specific profiles beyond simple bars/rods move to 7228.60 categories.

Import Tips & Compliance
• Provide detailed chemical analysis confirming O1 meets tool steel manganese/carbon thresholds to CBP upon entry
• Declare exact cold-forming process; any heat treatment beyond may shift to different headings
