Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If steel shims instead
Steel shimming foil/strip uses Chapter 73 articles of iron/steel.
If thicker copper shims >0.15mm
Thicker precision strip classifies as copper strip not foil.
If machinery gasket sets including foil
Assembled shim/gasket kits go to Chapter 84 machinery parts.
