Import Tips
• 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
