7608.20.00/6061 Aluminum Alloy Round Tube/China

6061 Aluminum Alloy Round Tube from China

Seamless round tubing made from 6061 aluminum alloy, commonly used in structural applications like frames and supports. It falls under HTS 7608.20.00 as it is a tube of aluminum alloys, where aluminum predominates but alloying elements like magnesium and silicon exceed non-alloyed limits. Typical outer diameter ranges from 0.5 to 6 inches with wall thicknesses from 0.035 to 0.5 inches.

Import Tips

• Verify alloy composition certificate showing aluminum >50% with Fe+Si >0.1% or other elements >1% to confirm 7608.20.00 classification

• Provide mill test reports (MTRs) documenting chemical analysis and mechanical properties to avoid reclassification as non-alloyed aluminum

• Ensure accurate dimensional specs in entry docs; tubes vs pipes distinguished by use (pressure vs structural)
