Cupro-Nickel C-70600 Rectangular Profile Rod
A rectangular profile rod made from C-70600 cupro-nickel alloy (90% copper, 10% nickel), used in marine and desalination applications for its corrosion resistance. Classified under HTS 7407.29.34.00 as a profile of copper-nickel base alloy, where nickel predominates over other elements and zinc is under 1%. Excludes simpler bars or rods.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains >1% but ≤3% lead
Lead content shifts classification from pure copper-nickel base to leaded copper-nickel-zinc profiles.
If of refined copper without nickel alloying
Pure copper profiles (no significant nickel) fall under refined copper headings, not alloys.
If machined into finished articles or parts
Further worked beyond profiles into specific components moves to Chapter 74 articles.

Import Tips & Compliance
• Verify alloy certification showing nickel >1% and zinc <1% to meet copper-nickel base alloy definition
• Provide mill test reports confirming profile extrusion (not bar/rod) to avoid reclassification
• Watch for anti-dumping duties on certain cupro-nickel from specific origins like Japan
