Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains >0.1% Fe+Si or alloying elements
Exceeds unalloyed purity limits per chapter note (a), shifting to aluminum alloys heading.
If imported as part of refrigeration equipment
Specific end-use in heat exchangers classifies under machinery parts, not generic tubes.
If shaped into specific profiles beyond tube form
Hollow bars/profiles differ from round tubes/pipes; form dictates Chapter 76 heading.

Import Tips & Compliance
• Obtain mill test certificate confirming aluminum purity ≥99% and no alloying elements exceed note limits (Fe+Si ≤0.1%)
• Ensure accurate measurement of tube dimensions; misclassification as 'alloyed' common pitfall if certifications missing
• Declare as 'other' non-aircraft tubes; provide end-use documentation to avoid reclassification
