Cold-Formed Sigma Profile
Sigma-shaped cold-formed section from nonalloy steel flat-rolled products, used in solar panel racking systems. Falls under HTS 7216.91.00.90 as other cold-formed shapes, not further worked. The unique sigma geometry provides enhanced load distribution.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for alloy steel versions
High-strength requirements shift to alloy steel angle/shape headings.
If pre-assembled into solar frames
Fabricated assemblies classified by function rather than component shapes.
If considered flat-rolled with slight forming
Minimal forming might keep classification in flat-rolled Chapter 72 headings.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide engineering drawings showing profile shape to confirm 'other shapes' status
• Test for alloy elements if steel appears unusually strong to avoid 7228 misclassification
• Declare exact forming temperature records to distinguish from hot-rolled processes
