HS Code for Lamellar copper powder

Lamellar copper powder is classified under HS code 7406.20. This classification is part of Chapter 74, which covers copper and articles thereof. Heading 7406 is dedicated to copper powders and flakes. The subheading 7406.20 specifically identifies powders of lamellar structure and flakes. The term "lamellar" refers to the shape of the particles, which are plate-like or flake-like rather than spherical or irregular. These powders are typically produced by ball milling or other mechanical processes that flatten the copper particles. This physical structure is critical for applications such as conductive inks, coatings, and metallic paints, where the overlapping flakes provide superior electrical conductivity or reflective properties. The classification is based entirely on the physical morphology of the copper particles rather than their chemical purity, provided they are predominantly copper.

Products Included

• Copper flakes
• Lamellar copper particles
• Bronze flakes (with high copper content)
• Copper leaf powder
• Conductive copper flake preparations

Common Misclassification

Lamellar copper powder is often confused with HS code 7406.10, which covers copper powders of non-lamellar structure (such as atomized spherical powders). The distinction is purely structural and usually requires microscopic verification. It may also be misclassified under 3212.90 if the powder is dispersed in a medium for use as a pigment, but the pure powder or flake form remains under 7406.20.

FAQ

What is the HS code for lamellar copper powder?

The specific HS code for copper powders of lamellar structure and copper flakes is 7406.20.

What defines a lamellar structure in copper powder?

A lamellar structure means the particles are shaped like thin plates or flakes, which allows them to overlap when applied to a surface.
