This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the Z-purlins are cold-formed from non-alloy steel
Cold-formed angles, shapes, and sections of iron or non-alloy steel are classified under heading 7216.
If the purlins are part of a prefabricated building structure
Prefabricated structural components for buildings are classified under 7308 when they form part of a complete structure.

Import Tips & Compliance
• Confirm the Z-purlins are welded, not cold-formed, to fall under 7301.20.00; cold-formed sections may be classified elsewhere
• Keep records of the welding process and steel grade
• Verify if the punched holes affect classification—they do not, as punching is allowed under the heading
