Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If any cold-forming applied
Cold-formed tool steel bars regardless of composition go to 7228.50.
If non-alloy base composition
Lacking alloy elements above de minimis classifies as nonalloy bars.
If clad or coated surface
Metal coating constitutes 'further worked' per chapter note.

Import Tips & Compliance
• Bright bars must prove no cold drawing; hot-rolled microstructure documentation needed
• 'Further worked' note excludes even light polishing; stay within hot-rolled tolerance
• Batch testing recommended; single heat variation can trigger full re-analysis
