Cupro-Nickel 70/30 Hollow Profile for Desalination Plant Piping from China
Hollow profile extruded from 70Cu-30Ni alloy for heat exchanger and piping systems in desalination plants, offering superior resistance to seawater corrosion and biofouling. HTS 7407.29.16.10 applies due to copper-nickel base alloy composition (nickel predominates) and hollow profile form. Used in straight lengths for subsequent fabrication into fittings.

Import Tips
• Require supplier certificates specifying exact Ni/Cu ratio (70/30) meeting copper-nickel base alloy definition
• Document profile's constant cross-section and length-to-diameter ratio to distinguish from pipes/tubes under 7411
