More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the profile is made of non-alloy aluminum
Hollow profiles of non-alloy aluminum are classified separately from those of aluminum alloys.
If the product meets the definition of tubes or pipes
Tubes and pipes of aluminum alloys are classified under heading 7608, not 7604.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• > Ensure the product is classified as a profile, not a tube or pipe, by confirming it does not meet the definition of tubes/pipes in Section XV Note 9(e)
• Provide a mill certificate showing the 6061-T6 alloy composition to support classification as an aluminum alloy
• Verify the profile is "hollow" with a uniform cross-section to avoid reclassification
