HS Code for Backed copper alloy foil

Backed copper alloy foil is classified under HS code 741022. This code specifically covers "Copper; foil, backed with paper, paperboard, plastics or similar backing material, of a thickness (excluding any backing) not exceeding 0.15mm, of copper alloys." The classification is determined by several key attributes: the primary material being a copper alloy, its form as a foil, the presence of a backing material (such as paper, plastic, or similar), and a specific thickness limitation for the copper alloy foil itself, not exceeding 0.15mm. This precise definition ensures that composite materials featuring thin copper alloy layers with added backing for structural integrity or specific functional properties are correctly categorized.

Products Included

• Copper alloy foil laminated with plastic for flexible printed circuits
• Brass foil (a copper alloy) backed with paper for decorative applications
• Bronze foil (a copper alloy) combined with a polymer film for shielding
• Copper-nickel alloy foil backed with a non-conductive material
• Backed copper alloy foil used in electromagnetic interference (EMI) shielding

Common Misclassification

Common misclassification can occur with HS code 741011, which covers "Copper; foil, not backed, of a thickness (excluding any backing) not exceeding 0.15mm, of refined copper." This code covers *unbacked* foil made of *refined copper*, not copper alloys. The key distinctions for 741022 are both the presence of a backing and the material being a *copper alloy*. Misclassification could occur if the alloy composition or the backing is overlooked. Another potential area of confusion is HS code 741012, "Copper; foil, not backed, of a thickness (excluding any backing) not exceeding 0.15mm, of copper alloys." This code covers *unbacked* foil made of *copper alloys*. The critical difference from 741022 is the *absence* of a backing material. Products with a backing, even if made of copper alloy and within the thickness limit, must be classified under 741022.

FAQ

What is the HS code for Backed copper alloy foil?

The HS code for Backed copper alloy foil is 741022. This code specifically covers "Copper; foil, backed with paper, paperboard, plastics or similar backing material, of a thickness (excluding any backing) not exceeding 0.15mm, of copper alloys."

How does HS code 741022 differentiate between refined copper and copper alloys?

HS code 741022 explicitly specifies "of copper alloys," meaning the metallic foil component must be composed of an alloy where copper is the predominant element, rather than pure or refined copper. Other HS codes (e.g., 741011) are designated for foils made of "refined copper," highlighting this material distinction within the broader copper foil category.
