Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sheets have a paint or plastic coating in addition to the aluminum-zinc layer
This covers flat-rolled products painted, varnished, or coated with plastics, which would apply if the organic coating is significant.
If the sheets are less than 600 mm wide after processing
For narrower flat-rolled products of iron or non-alloy steel, plated or coated with aluminum-zinc alloys.

Import Tips & Compliance
• Verify the steel sheets are over 600 mm wide and that the aluminum-zinc coating is applied to both sides, as is typical for HVAC-grade material
• Provide a mill certificate indicating the coating weight (e.g
• AZ150) and steel grade for CBSA verification
• If the sheets are cut to specific duct sizes, ensure they are not further worked (e.g
• folded or punched) beyond simple cutting, as this could change classification
