Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unwrought or semi-fabricated
Unworked aluminum alloys in bar/rod form before machining into fittings are in 7604.
If steel flanges or flanged fittings
Iron/steel pipe flanges shift to 7307, material determines chapter.
If parts of pumps or compressors
Fittings designed exclusively for machinery parts fall under Chapter 84 end-use.

Import Tips & Compliance
• Document size compatibility with standard tubes (e.g
• 1/2" to 3/4") to prove pipe fitting purpose
• Obtain supplier affidavits confirming aluminum content >99% or alloy specs per chapter notes
• Beware of sets with tubes; classify as sets under GRI 3 if not solely fittings
