Import Tips & Compliance
• > Verify the product is a profile, not a tube or pipe, by checking the cross-section definition in Note 9(e)
• Provide alloy composition documentation to confirm it is an aluminum alloy
• If the profile is used in machinery frames, ensure it is not further worked into an article of another heading
