HS Code for Cupronickel strip

Cupronickel strip is classified under HS code 7409.40 because it falls within the category of copper plates, sheets, and strip with a thickness exceeding 0.15mm. The classification is determined by the metallurgical composition of the alloy, specifically copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). According to the General Rules of Interpretation (GRI) and the Chapter 74 notes, these products must be of a thickness that distinguishes them from copper foil. The material is typically produced through rolling processes and is used in applications requiring high corrosion resistance, such as marine hardware or electrical components. The 7409.40 subheading specifically isolates these alloys from refined copper or other copper-tin (bronze) and copper-zinc (brass) alloys, ensuring that the specific physical properties of the nickel-containing alloy are accounted for in trade statistics and tariff applications.

Products Included

Common Misclassification

A frequent error involves misclassifying these items under HS code 7410.12 or 7410.22. These codes are reserved for copper foil, which is defined as having a thickness not exceeding 0.15mm. If the cupronickel strip is thinner than this threshold, it must move to Chapter 7410. Additionally, if the nickel content by weight exceeds the copper content, the product may be misclassified under Chapter 75 (Nickel and articles thereof), specifically 7506.10 or 7506.20. It is also common to see confusion with HS code 7407.29, which covers bars and rods; however, strips are distinguished by their rectangular cross-section and flat-rolled nature.

FAQ

What is the HS code for Cupronickel strip?

The primary HS code for cupronickel strip with a thickness exceeding 0.15mm is 7409.40.

How is the thickness measured for classification?

Thickness is measured excluding any coating or cladding. If the thickness is 0.15mm or less, the product is classified as foil under HS code 7410 rather than strip under 7409.
