Products classified under HTS 2846.10.00.50
Cerium Oxide (CeO2) Polishing Powder
High-purity cerium oxide powder used for precision polishing of glass surfaces in optical lenses and displays. It falls under HTS 2846.10.0050 as a chemically defined inorganic compound of the rare-earth metal cerium, specifically classified as 'other' cerium compounds. This subheading covers cerium-based polishing agents not elsewhere specified.
Cerium Nitrate Hexahydrate (Ce(NO3)3·6H2O)
Crystalline cerium nitrate used as a catalyst precursor and in specialty glass manufacturing. Classified under HTS 2846.10.0050 as an 'other' inorganic compound of cerium, a rare-earth metal, meeting Chapter 28 definitions for chemically defined compounds. Excludes salts covered in other specific headings like nitrates of heading 2834.
Cerium Acetylacetonate
Organometallic cerium compound used as a precursor in chemical vapor deposition for thin films. It qualifies for HTS 2846.10.0050 as an organic compound of rare-earth cerium, per subheading note definitions linking to Chapter 29 organic compounds. Ideal for electronics and catalysis applications.
Cerium Fluoride (CeF3) Crystals
Synthetic cerium fluoride crystals used in optical coatings and laser components. Falls under HTS 2846.10.0050 as an inorganic cerium compound, distinct from alkali fluorides, per Chapter 28 exclusions and definitions. Not classified as optical elements per note 8(h).
Cerium Iodide (CeI3) Powder
Cerium iodide powder employed as a scintillator material in radiation detectors. Classified in HTS 2846.10.0050 as an 'other' inorganic compound of cerium, adhering to chemically defined criteria and excluding luminophores of heading 3206 per Chapter notes.
Cerium Sulfate Octahydrate
Hydrated cerium(IV) sulfate used in water treatment and as an oxidizing agent. It is an 'other' cerium compound under HTS 2846.10.0050, as sulfates of rare-earths are not covered by general sulfate headings (2833) per Chapter structure.
Cerium Ammonium Nitrate
Double salt of cerium and ammonium nitrate used in organic synthesis as an oxidant. HTS 2846.10.0050 applies as a cerium compound, but note 5 directs certain double salts to 2842; classified here as 'other' per statistical reporting.
Nanocrystalline Cerium Dioxide
Nano-sized CeO2 particles for catalytic converters and UV blockers. Remains under HTS 2846.10.0050 as chemically defined cerium oxide, particle size does not change classification unless prepared (3824).
