HS Code for Laminated copper alloy foil

Laminated copper alloy foil falls under HS code 7410.22. This classification is reserved for foil made of copper alloys, such as brass or bronze, where the thickness of the metal layer does not exceed 0.15mm. The term "laminated" or "backed" indicates that the foil is attached to a supporting material like paper, plastic, or paperboard. This backing is essential for handling very thin foils that would otherwise be too fragile for industrial processes. Copper alloy foils are often chosen for their specific mechanical properties, corrosion resistance, or aesthetic qualities in decorative and technical applications. The classification is determined by two main factors: the chemical composition of the metal (being an alloy rather than refined copper) and the presence of a secondary material layer providing structural support.

Products Included

• Brass foil laminated with plastic for decorative trim
• Bronze foil backed with paper for hot stamping
• Copper-nickel alloy foil with polyester backing for electronics
• Laminated copper alloy shielding for specialized cables

Common Misclassification

This product is often confused with HS code 7410.21, which is specifically for refined copper foil. It is also misclassified under 7410.12, which covers copper alloy foil that is not backed. Importers must verify the metallurgical assay to ensure the copper is indeed an alloy (such as brass) rather than refined copper to avoid using the incorrect sub-heading.

FAQ

What is the HS code for laminated copper alloy foil?

The correct HS code for copper alloy foil that is backed with paper, plastics, or similar materials is 7410.22.

What is the maximum thickness for this classification?

The copper alloy foil layer must not exceed a thickness of 0.15mm, excluding the thickness of the backing material.
