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.

Import Tips & Compliance
• Document that the pre-drilled holes are for assembly purposes and do not transform the sheet into a part of a machine (which would fall under Section XVI)
• Provide the alloy composition and thickness specifications to support classification under 7409.40.00
• Consult a customs broker if the tube sheet is imported with other heat exchanger components
