HS Code for Cupro-nickel wire

Cupro-nickel wire is classified under HS code 7408.22. This code is part of Chapter 74, which covers copper and articles thereof. Heading 7408 is dedicated to copper wire, and the subheading 7408.22 specifically identifies wire made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). To be classified here, the product must meet the definition of "wire" provided in the Chapter 74 notes: rolled, extruded, or drawn products, in coils, which have a uniform solid cross-section along their whole length in the shape of circles, ovals, rectangles, or other polygons. The alloy composition is the deciding factor for this subheading; cupro-nickel alloys are valued for their resistance to corrosion, particularly in marine environments, and their electrical conductivity properties, which distinguishes them from refined copper wire or other copper alloys like brass or bronze.

Products Included

• 70/30 Cupro-nickel alloy wire
• 90/10 Cupro-nickel alloy wire
• Nickel silver wire (Copper-Nickel-Zinc)
• Corrosion-resistant marine grade copper-nickel wire
• Electrical resistance wire made of cupro-nickel

Common Misclassification

Cupro-nickel wire is often misclassified under 7408.11 or 7408.19, which are reserved for wire of refined copper (non-alloyed). It may also be confused with 7408.21, which is for copper-zinc base alloys (brass). Furthermore, if the nickel content exceeds the copper content by weight, the product would be classified under Chapter 75 (Nickel) rather than Chapter 74, specifically under 7505.22 for nickel alloy wire.
