Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solid T-shaped cross-section
Solid non-rectangular profiles of alloys go to 7604.29.30, excluding hollows.
If shaped like plates/sheets after processing
If flattened or processed beyond extrusion, may classify under clad or other aluminum plates.
If sold as set with fittings
Cloth, grill, netting or fencing with profiles classifies under 7616.91 if assembled.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Submit detailed engineering drawings showing hollow cross-section to avoid reclassification as solid T-bars
• Certify non-alloyed content under 99% aluminum per subheading note (a) to stay in alloy category
