Compounds, inorganic or organic, of rare-earth metals, of yttrium or of scandium, or of mixtures of these metals
11 declarable lines
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.
Products in this heading
- Cerium oxide polishing powder
- Cerium chloride
- Lanthanum oxide
- Yttrium oxide
- Scandium oxide
- Mixed rare-earth chlorides
- Lanthanum carbonate
- Yttrium bearing concentrate containing 20 to 84% yttrium oxide equivalent
How to choose the right subheading
- Identify the chemical form: oxide, chloride, carbonate, or another compound.
- Check whether the product is a cerium compound; cerium compounds go in 2846.10.
- For non-cerium oxide or chloride mixtures, identify the predominant metal: lanthanum, yttrium, scandium, or other.
- For yttrium bearing materials, check the yttrium oxide equivalent content by weight.
- Use the residual other lines only when no more specific rare-earth compound line applies.
Often confused with
- Heading 2805Cerium metal or mischmetal
Rare-earth metals and alloys are classified in heading 2805, not as compounds.
- Heading 2844Radioactive rare-earth isotopes or their compounds
Radioactive isotopes and their compounds are covered by heading 2844.
- Heading 2852Mercury compounds
Mercury compounds are classified in heading 2852.
- Heading 2853Rare-earth phosphides
Phosphides are classified in heading 2853.
Frequently asked questions
What is the HTS code for cerium oxide?
Cerium oxides are classified under 2846.10.00.10. The general (MFN) duty rate is 5.5%.
What is the duty on mixed rare-earth chlorides?
Mixtures of rare-earth chlorides other than cerium chlorides with yttrium or scandium as the predominant metal are classified under 2846.90.20.82, and the general (MFN) rate is Free. The residual rare-earth chloride mixture line 2846.90.20.84 also has a general (MFN) rate of Free.
How do I classify a lanthanum carbonate mixture?
A mixture of rare-earth carbonates other than cerium carbonate containing lanthanum as the predominant metal is classified under 2846.90.80.70. The general (MFN) duty rate is 3.7%.
