Alternative Classifications

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

2846.10.00Higher: 5.5% vs Free

If sold as individual pure oxides without mixing

Pure, unmixed rare-earth oxides like cerium oxide alone classify under the specific single-compound subheading.

3824.99Higher: 15% vs Free

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.

2846.90.80Higher: 3.7% vs Free

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.
