Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in coil form or unfinished tubes
Aluminum tubes of aluminum alloys are in 7608 if not fabricated into fittings.
If made of copper instead of aluminum
Copper tube/pipe fittings are classified under Chapter 74, separate from aluminum.
If for industrial nails or similar profiles
Non-fitting aluminum profiles like threaded rods go to 7616, not pipe-specific fittings.

Import Tips & Compliance
• Include detailed engineering drawings showing threaded design for tube/pipe use to support classification
• Test for pressure ratings and certify compliance with ASTM B88 or similar standards for import verification
• Avoid bulk packaging misclassified as scrap; ship as finished fittings with individual packaging
