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. Despite the drilling, it remains classified as a copper-nickel base alloy sheet under tariff item 7409.40.00, as the drilling does not give it the character of a distinct article.

Import Tips & Compliance
• The pre-drilled holes may be considered a working process, but if the sheet remains identifiable as a plate or sheet, it stays in this item
• Document the intended use as a tube sheet to support classification
• Verify that the drilling does not transform the product into a part of a machine, which would fall under Section XVI
