Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refined copper version >0.15mm
Pure copper thick forms separate from thin alloy foils.
If pre-formed into electrical connectors
Advanced manufacture into electrical apparatus parts moves to Chapter 85.
If plastic coated for electrical insulation
Coatings qualify as backing, changing to backed foil subheading.

Import Tips & Compliance
• Certify phosphorus content as trace (<0.5%) doesn't alter base alloy classification rules
• Ultra-thin foils require special packaging; declare exact gauge tolerance
• Avoid reclassification as 'wire' if wound on small diameter spools
