6061-T6 Aluminum Hollow Square Profile from China
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
