Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the foil is a part of an electric capacitor rather than an accumulator
Parts of electric capacitors may be classified under heading 8532.
If the foil is a general aluminum foil not specific to energy storage
Aluminum foil may be classified under Chapter 76 if not identifiable as a battery part.

Import Tips & Compliance
• Classify this foil as a battery part, not as a general aluminum foil, to ensure correct duty treatment
• Provide technical documentation showing its etched surface and role as a current collector in supercapacitors
• Note that supercapacitors may be classified under heading 8532—verify if the foil should be classified there instead
