U.S. imports of Unbacked Refined Copper Foil (Not Over 0.15 mm Thick) (HS 741011) totaled $46.5M in August 2026, imported from 23 countries.
Importers of Unbacked Refined Copper Foil (Not Over 0.15 mm Thick) paid $20.1M in duties in August 2026, an average duty rate of 38.53% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataRefined copper foil in its unbacked form — no substrate laminated to the copper layer — is a critical input for printed circuit board (PCB) manufacturing, lithium-ion battery current collectors, and electromagnetic shielding applications. The entire heading resolves to a single 10-digit line, 7410110000, making classification straightforward, though Section 232 tariff exposure on copper articles is a factor importers must evaluate. South Korea dominates US supply, with Malaysia and Taiwan also significant sources, reflecting the concentration of advanced electronics manufacturing in East Asia.

Unbacked foil consists solely of the copper layer with no bonded substrate material. Once the foil is laminated to a dielectric, paper, plastic, or other backing material, it shifts to the backed foil headings (7410.21 or 7410.22). The distinction is critical at entry because the two groups carry different tariff lines and, in some cases, different duty treatment.
The heading covers foil not exceeding 0.15 mm (150 microns) in thickness. Standard PCB-grade electrodeposited copper foil typically runs 9–70 microns, well within this limit. Rolled-annealed foil used in flexible circuits also falls comfortably below the threshold, so thickness is rarely a classification issue for electronics-grade material.
