Cold-Formed C-Purlin Channel
A cold-formed C-shaped structural channel made from flat-rolled nonalloy steel, used in metal building frameworks for roofs and walls. It falls under HTS 7216.91.00.90 as a cold-formed angle, shape, or section, not further worked, distinguishing it from hot-rolled or U-shaped profiles. These purlins provide support for roofing materials in construction applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hot-rolled rather than cold-formed
Hot-rolled angles, shapes, and sections fall under different subheadings based on production method.
If assembled into structural steel framing
Fabricated structures from these profiles are classified by end-use in Chapter 73.
If subjected to further working like coating or painting
Surface treatments such as coating move products to 'further worked' categories per Chapter 72 notes.

Import Tips & Compliance
• Verify cold-forming process documentation to distinguish from hot-rolled products under 7216.61
• Provide mill test certificates confirming nonalloy steel composition to avoid alloy steel headings
• Check for any surface treatments that could reclassify as 'further worked' under 7216.92
