Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If concrete reinforcing with ribs/grooves
Deformed bars for concrete reinforcement use 7214 per specific Chapter 72 note (c).
If in coils rather than straight lengths
Cold-formed bars in coils classify under 7213 for coiled products.
If machined into finished articles like bolts
Finished metal articles beyond simple bars move to Chapter 73.

Import Tips & Compliance
• Include chemical analysis certificate showing lead (0.15-0.35%) and sulfur levels defining free-cutting properties
• Specify cross-sectional dimensions accurately; hexagonal shapes must still meet 'bars and rods' criteria
• Avoid declaring as 'tool steel' if elements don't match Chapter 72 note (e) definitions
