Last updated: April 2026 dataCopper alloy foil bonded to a backing material — classified under a single 10-digit line, 7410220000 — occupies a specialized niche in flexible circuit assemblies, EMI shielding tapes, and specialty packaging where alloy properties such as spring temper or reduced conductivity are preferred over pure copper. China leads US imports under this heading, followed by Ireland and Germany, a supplier mix that reflects both high-volume manufacturing and precision specialty production in Europe.

If the backing material becomes the essential character of the article — for example, a composite tape where the adhesive or polymer layer predominates — classification may shift to Chapter 39 (plastics) or Chapter 76 (aluminum foil composites) depending on composition. The relative thickness, weight, and commercial function of each layer guide the essential-character analysis under GRI 3.
Backed refined copper foil (7410.21) and backed copper alloy foil (7410.22) are separate HS subheadings and may carry different normal trade relations (NTR) duty rates. Importers should verify the mill certificate confirms alloy content, as misclassifying an alloy product as refined copper — or vice versa — can result in underpayment or overpayment of duties and potential penalties.
