Import Tips
• > Verify that the product is a profile, not a tube or pipe, by ensuring it does not have a uniform wall thickness with concentric cross-sections
• Document the alloy composition to confirm it is an aluminum alloy, not pure aluminum
• If the profile is cut to length with no further working, it remains classifiable under this item
