HS Code for Cupronickel plate

Cupronickel plates are classified under HS code 7409.40. This classification is governed by the General Rules of Interpretation (GRI) and the specific legal notes of Chapter 74, which covers copper and articles thereof. Heading 7409 is dedicated to copper plates, sheets, and strip with a thickness exceeding 0.15mm. The classification further narrows down to subheading 7409.40, which specifically identifies alloys of copper-nickel (cupro-nickel) or copper-nickel-zinc (nickel silver). To be classified here, the copper content must predominate by weight over each of the other elements. If the nickel content were to exceed the copper content, the product would shift to Chapter 75. These plates are typically manufactured through rolling processes and are defined by their flat, non-coiled shape. The material is highly sought after in industrial applications due to its exceptional resistance to biofouling and corrosion, particularly in seawater, making it a standard material for marine engineering and desalination plants. The thickness must be uniform and exceed 0.15mm to distinguish it from foil.

Products Included

• Cupronickel industrial plates
• Nickel silver sheets
• Marine-grade cupro-nickel strips
• Copper-nickel-zinc alloy plates
• Corrosion-resistant copper alloy sheets

Common Misclassification

A frequent error involves confusing 7409.40 with 7410.12. The primary distinction is thickness; products 0.15mm or thinner are classified as copper foil under heading 7410. Additionally, if the alloy contains more nickel than copper by weight, it must be classified under heading 7506 as nickel plates or sheets. Another common mistake is using 7409.11, which is reserved for refined copper rather than copper alloys.

FAQ

What is the HS code for cupronickel plate?

The HS code for cupronickel plate is 7409.40, which covers plates, sheets, and strip of copper-nickel base alloys with a thickness exceeding 0.15mm.

What is the difference between a plate and a foil in HS classification?

In Chapter 74, the distinction is based on thickness. Plates and sheets (7409) must have a thickness exceeding 0.15mm, while foils (7410) are 0.15mm or thinner.
