Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of copper-zinc base alloys (brass tubing)
Brass refrigeration tubing with zinc > other elements but <5% nickel classifies under alloy subheading per note (a).
If imported as parts of air conditioning machines
Pre-bent or flared tubes for specific AC units are classified by function in Chapter 84 machinery parts.
If very thin-walled and considered copper wire rather than tube
Extremely thin tubes resembling flattened wire fall under other copper articles if not qualifying as pipes/tubes.

Import Tips & Compliance
• Include HVAC-specific certifications like UL or NSF to demonstrate end-use and prevent reclassification as general pipe
• Document wall thickness and temper (e.g
• annealed) matching ACR tubing standards to confirm 'other' tube status
