Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically etched for capacitors
Unetched rolled aluminum foil of ≥99% purity falls under the not etched/plain subheading.
If printed or patterned beyond etching
Printing or decorative patterns classify as 'other' non-etched/non-capacitor foils.
If for hybrid integrated circuit use
Foil integrated into electronic circuits may shift to Chapter 85 as hybrid circuit parts.
