Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of copper alloys like brass or bronze
Shifts to copper alloy subheading if zinc or tin meets brass/bronze alloy definitions per chapter notes.
If pre-patterned or etched for specific circuits
Becomes insulated wire/cable or PCB if processed beyond plain foil cladding.
If imported as finished laminate without copper
Plastics sheet heading applies if no copper foil layer present.

Import Tips & Compliance
• Verify copper thickness excluding backing does not exceed 0.15 mm and confirm single-sided configuration via cross-section analysis
• Provide material test reports certifying the base is wholly plastics-impregnated glass (e.g
• FR4) to avoid misclassification
