Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reduced to metallic mischmetal alloy
Metallic mixtures of rare-earths (not oxides) classify separately under 'other' rare-earth mixtures.
If doped for phosphor/luminophore use
Inorganic luminophores/products used as such excluded from Chapter 28 per Chapter Note 5(d).
If mixed with >20% organic phosphors
Mixtures with organic components become organo-inorganic preparations under Chapter 38.
