Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fabricated into duct structures
Assembled/complex fabricated steelwork shifts from flat products to Chapter 73.
If clad with other metal besides zinc
Coating material specificity—non-zinc cladding uses different subheading.
If painted, varnished, or plastic-coated
Alternative coatings beyond zinc plating classify separately.

Import Tips & Compliance
• Coating must cover entire surface; spot-plating risks uncoated classification
• Width includes any adhesive backing if integral—measure total dimension
