Cupro-Nickel 90/10 Unwrought Ingot
Unwrought ingots of 90% copper and 10% nickel alloy, known as cupro-nickel, used primarily for corrosion-resistant applications in marine and desalination equipment. This falls under HTS 7403.29.0110 as a copper-nickel base alloy in unwrought form, containing no more than 1% zinc per chapter definitions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If zinc predominant over nickel
Shifts to copper-zinc base alloys (brasses) per subheading note (a) when zinc exceeds other elements.
If tin predominant with ≥3% tin
Qualifies as copper-tin base alloys (bronzes) under subheading note (b).
If classified as master alloy for remelting
Master alloys of heading 7405 are excluded from 7403, used specifically for alloy production.

Import Tips & Compliance
• Verify alloy composition via certified mill test reports showing nickel predominance and zinc ≤1% to confirm copper-nickel base alloy status
• Ensure documentation specifies 'unwrought' form; wrought products like bars shift to Chapter 74 headings 7404-7419
