Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated with zinc other than electrolytic or hot-dip
Alternative zinc coating processes (not electrolytic/hot-dip) use different subheadings.
If alloy steel composition
Alloy steels (specified elements per Chapter 72 notes) classify in Chapter 72 heading 7225.
If imported as part of complete HVAC assembly
Assembled into finished HVAC equipment moves to Chapter 84 machinery classification.

Import Tips & Compliance
• Document plating method; electrolytic produces smoother finish than hot-dip
• Confirm carbon content <0.6% for nonalloy classification with chemical analysis
• Avoid classifying pre-cut lengths over certain dimensions that may be considered fabricated articles
