Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not heat-treatable per statistical note 7
Non-heat-treatable alloys like 5000 series go under other hollow aluminum alloy profiles.
If further manufactured into tubes or pipes
Hollow profiles worked into tubes for fluid conveyance change to Chapter 76 tube headings.
If imported as part of an assembly for machinery
Articles of aluminum n.e.s. apply if not qualifying as simple extruded profiles.

Import Tips & Compliance
• Verify alloy composition meets statistical note 7 for heat-treatable industrial alloys (e.g
• 6061 series) with mill test certificates
• Ensure profiles are extruded hollow shapes; solid bars shift to 7604.29
• Declare exact temper (e.g
• T6) and dimensions to avoid misclassification as tubes under 7608
