This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as individual pure oxides without mixing
Pure, unmixed rare-earth oxides like cerium oxide alone classify under the specific single-compound subheading.
If contains organic stabilizers or additives exceeding incidental levels
Mixtures with significant organic components fall into prepared chemical mixtures rather than pure inorganic Chapter 28.
If consists of other compounds like rare-earth nitrates or mixtures thereof
Only oxide or chloride mixtures qualify here; other rare-earth compounds go to the residual 'other' subheading.
