Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specific light REE oxide mixtures
La-Ce-Pr-Nd mixtures have dedicated statistical breakout.
If containing cerium oxide impurities
Any cerium shifts out of 'except cerium oxides' subheading.
If surface-coated oxide particles
Coated or prepared forms become chemical preparations.
