6061-T6 Aluminum Hollow Square Profile
A hollow square profile extruded from 6061-T6 aluminum alloy, commonly used in structural frameworks and machinery components. It qualifies under HTS 7604.21.00.90 as it is a hollow profile of aluminum alloys, not specifically rectangular or hollow for specific uses. The alloy composition exceeds pure aluminum limits with magnesium and silicon additions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solid rectangular cross-section
Solid profiles of aluminum alloys fall under 7604.29, excluding hollow forms.
If further machined into finished articles
Machined or fabricated aluminum products beyond simple profiles classify as other articles in 7616.
If assembled into welded tubes/pipes
Welded hollow sections of aluminum alloys for structural use move to iron/steel chapter equivalents if applicable, but primarily material-based.

Import Tips & Compliance
• Verify alloy composition certificate showing aluminum predominance and other elements exceeding 1% total to confirm 7604 classification
• Provide mill test reports for dimensional specs to distinguish hollow profiles from bars/rods under 7604.21
• Avoid common pitfall of declaring as solid profiles which shift to 7604.29; ensure clear cross-section documentation
