Products classified under Tariff item 7409.40.00
Cupro-Nickel 70/30 Plate
Rectangular plate of 70% copper-30% nickel alloy, exceeding 0.15 mm thickness, designed for corrosion-resistant applications in chemical processing. It qualifies as a copper-nickel base alloy (cupro-nickel) plate under tariff item 7409.40.00, as the nickel content exceeds 1% and the alloy is not a copper-zinc or copper-tin base alloy.
Cupro-Nickel 90/10 Sheet
A flat sheet of 90% copper and 10% nickel alloy (cupro-nickel) with thickness exceeding 0.15 mm, used primarily for heat exchanger plates in marine and desalination systems. This product falls under tariff item 7409.40.00 as a copper-nickel base alloy sheet, with nickel content above the 1% threshold for copper-nickel base alloys.
Cupro-Nickel Chemical Processing Sheet
Corrosion-resistant sheet of cupro-nickel for chemical tanks, with thickness exceeding 0.15 mm. It is classified under tariff item 7409.40.00 as a copper-nickel base alloy sheet, given the nickel content is above the threshold for copper-nickel base alloys.
Cupro-Nickel Condenser Tube Sheet
Pre-drilled tube sheet from cupro-nickel 90/10 alloy, thickness >0.15 mm, for heat exchanger assemblies in power plants. Although pre-drilled, it remains classified as a copper-nickel base alloy sheet under tariff item 7409.40.00, as the drilling does not confer the character of a finished article of another heading.
Cupro-Nickel Desalination Plant Plate
Plate for desalination evaporators, made of cupro-nickel alloy, with thickness exceeding 0.15 mm. It falls under tariff item 7409.40.00 as a copper-nickel base alloy plate, given the nickel content is above the threshold for copper-nickel base alloys.
Cupro-Nickel Heat Exchanger Plate
Flat plate of 90/10 cupro-nickel for heat exchangers, thickness >0.15 mm. It is classified under tariff item 7409.40.00 as a copper-nickel base alloy plate, with nickel content exceeding the 1% threshold for copper-nickel base alloys.
Cupro-Nickel Marine Grade Strip
Strip of UNS C70600 cupro-nickel for seawater applications, thickness exceeding 0.15 mm. It falls under tariff item 7409.40.00 as a copper-nickel base alloy strip, with nickel content above the threshold for copper-nickel base alloys.
Cupro-Nickel Power Plant Condenser Sheet
Sheet for power plant condensers, made of 70/30 cupro-nickel, with thickness exceeding 0.15 mm. It is classified under tariff item 7409.40.00 as a copper-nickel base alloy sheet, given the nickel content is above the threshold for copper-nickel base alloys.
