Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used solely for electroplating decorative finishes
Electrodes specifically for plating aesthetic metal layers have separate statistical reporting separate from industrial electrowinning.
If when part of complete electrowinning centrifuge equipment
Integrated into filtering/centrifuging machinery for metal recovery, classification moves to Chapter 84 machinery.
If primarily functioning as sacrificial anodes
Consumable carbon anodes for corrosion protection in electrolytes classify under inorganic bases and oxides.
