Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If defined platinum compounds like chloroplatinic acid
Chemically defined salts or acids of platinum go under specific compounds subheading.
If supported on carbon as finished catalyst
Catalysts with precious metal on carrier classify as supported catalysts.
If chemical mixture for industrial use
Complex preparations not purely colloidal fall into chemical mixtures.
