Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from copper-zinc base alloys (brass)
Brasses, where zinc predominates over other elements (per note a), go to 7411.21.
If imported as complete heat exchanger assembly
Assembled units with tubes function as heat exchangers, classified by end-use in Chapter 84.
If cut to length as tube fittings/parts
Short lengths prepared as components for assembly classify as copper fittings, not tubes.

Import Tips & Compliance
• Label as 'refined copper' with chemical analysis; impure copper shifts to 7411.21
• Avoid bundling with fittings; sets may classify under 7412 or as parts
