Polyimide Copper Clad Laminate for Flex PCBs
Flexible copper clad laminate using polyimide film backed with refined copper foil ≤0.15mm thick, designed for flexible printed circuits. The copper provides conductive layers on the polymer backing. Classified under HTS 7410.21.3060 as other backed copper clad laminates of refined copper.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not configured as laminate but simple backed foil
Paper/paperboard-backed copper foil uses different subheading; laminates with plastic backings are distinctly 'copper clad laminates'.
If for bare polyimide film without copper
Unclad polymer films classify under Chapter 39 non-cellular plastic sheets, missing copper foil component.
If copper content <5% of total weight
Low copper composite articles may shift to Chapter 74 other articles if not primarily foil-backed laminate.

Import Tips & Compliance
• Confirm polyimide as the backing material and copper purity as refined; retain supplier certificates for alloy content
• Declare exact thickness measurement method excluding backing to prevent disputes over 0.15mm limit
• Avoid common error of classifying as finished flex PCB; specify as raw clad material only
