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 with selective surface powder coating
Surface-worked copper bars/tubes for heat transfer move to 7415 nail/pipe category.
If assembled into complete solar collectors
Finished solar thermal collectors classify under Chapter 84 heat exchange machinery.
If copper-nickel alloys for seawater resistance
Cupronickel alloys (note (d)) use different subheading than refined copper.

Import Tips & Compliance
• Declare uncoated status if absorber coating absent; solar energy end-use may qualify incentives
• Pitfall: classifying absorber-coated tubes as 'worked' under 7412
