Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unwrought alloy
Unwrought Cu-Ni forms (not drawn into wire) stay in 7404 before working.
If formed into tubing
Drawn Cu-Ni tubing for heat exchangers is pipes under Chapter 73.
If coated with non-metal like varnish
Non-metallic coatings (e.g., enamel) keep it in uncoated subheading but watch for metal plate shift.

Import Tips & Compliance
• Certify Zn ≤1% and Ni predominance to qualify under note (d); excess Zn shifts to nickel silver
• Specify drawn wire form; tubes/pipes in 7411 have different rates
• For marine end-use, note ASTM B127 specs but classify by HTS material rules
