6061-T6 Aluminum Hollow Square Profile from Mexico

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.

Import Tips

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
