Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3801.10Same rate: 35%

If larger particle size for industrial non-battery uses

Graphite over 1 mm average diameter shifts to block/plate forms under different artificial graphite subheading.

2840.30.00Higher: 38.7% vs 35%

If heavily doped resembling perovskite structures

High dopant concentrations creating defined crystal structures may classify as synthetic metal carbides rather than modified graphite.

8545.11.00Same rate: 35%

If pre-coated onto current collector foil

Electrode assemblies with graphite coating become ceramic capacitors or battery electrodes under Chapter 85.
