About heading 2846

Compounds, inorganic or organic, of rare-earth metals, of yttrium or of scandium, or of mixtures of these metals

Heading 2846 covers inorganic or organic compounds of rare-earth metals, yttrium, and scandium, including mixtures of these metals. The heading first separates cerium compounds from all other compounds. The other part is split by chemical form and composition, mainly rare-earth oxide or chloride mixtures, yttrium bearing materials, rare-earth carbonates, and residual other compounds.
