FR-4 Copper Clad Laminate Double-Sided
Double-sided copper clad laminate made with FR-4 epoxy resin impregnated glass fiber base, featuring refined copper foil on both sides with thickness not exceeding 0.15 mm. Used primarily as the foundational material for manufacturing multilayer printed circuit boards (PCBs). Falls under HTS 7410.21.3040 due to its plastic-impregnated glass base and copper cladding on both sides.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper clad on only one side
Single-sided copper clad laminates on plastics-impregnated glass base are classified separately within the same subheading.
If made with copper-zinc base alloys (brasses)
Changes to copper alloy heading when base metal is brass rather than refined copper, per chapter subheading note (a).
If imported as finished PCB without exposed copper foil
Completed printed circuit boards shift to plastics chapter based on predominant material and function.

Import Tips & Compliance
• Verify copper thickness excludes backing and does not exceed 0.15 mm; provide lab test reports for customs verification
• Include material composition certificates confirming plastics-impregnated glass base and refined copper alloy compliance
• Avoid misclassification as single-sided by clearly documenting 'copper on both sides' in invoices and packing lists
