Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-flake high-purity copper powder
Atomized spherical copper for same applications classified as general copper powder.
If insulating fittings with copper filler
EMI shielding compounds as finished insulating parts fall under Chapter 85 electrical insulators.
If pickling preparations containing copper flakes
If used in chemical processing compounds, may shift to Chapter 38 preparations.
