Monel 400 Copper-Nickel Alloy Billets
Monel 400 is a solid-solution nickel-copper alloy in unwrought billet form, ideal for marine and chemical applications due to its resistance to seawater corrosion. The material is cast into basic shapes for hot working or forging. Falls under HTS 7502.20.00.00 as nickel alloys remain nickel-based despite copper content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper content exceeds nickel
Copper-nickel alloys become copper-based under Chapter 74 when nickel <50%.
If after hot-rolling into plate
Once processed beyond unwrought state, moves to Chapter 75 worked forms.
