U.S. exports of backed refined copper foil & copper-clad laminates (not over 0.15 mm thick) (HS 741021) totaled $7.2M in July 2026.
Importers of Backed Refined Copper Foil & Copper-Clad Laminates (Not Over 0.15 mm Thick) paid $2.7M in duties in July 2026 — an effective duty rate of 52% on $5.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataBacked refined copper foil — where the copper layer is bonded to a substrate such as fiberglass-reinforced epoxy — is the foundational material for copper-clad laminates (CCL) used in rigid and multilayer PCB fabrication. The US schedule distinguishes copper-clad laminates (7410213000 series, including double-sided glass-reinforced panels at 7410213040) from general backed refined copper foil (7410213020) and other backed forms (7410216000). Taiwan and Japan are the leading suppliers, consistent with their dominant roles in the global CCL and PCB supply chain.

Copper-clad laminates are rigid composite panels — typically copper foil bonded to a glass-fiber-reinforced resin substrate — classified under the 7410213000 series. General backed foil (7410213020) covers copper foil adhered to flexible or non-rigid substrates. The substrate type, rigidity, and intended PCB application all inform which 10-digit line applies.
Copper-clad laminates sourced from China have been subject to Section 301 tariffs. Given that Taiwan and Japan lead supply under this heading, some importers have shifted sourcing to reduce Section 301 exposure, though origin rules and substantial transformation analysis are essential when laminates undergo further processing before US entry. A licensed customs broker should be consulted for current applicability.
