Lanthanum-Dominant Rare Earth Carbonate Mixture
A chemically defined mixture of rare-earth carbonates where lanthanum carbonate is the predominant component, used primarily in the production of high-purity rare earth oxides for catalysts and phosphors. This falls under HTS 2846.90.80.70 as it is a mixture of rare-earth carbonates other than cerium carbonate with lanthanum predominant, per Chapter 28 notes on inorganic compounds. It is supplied as a fine white powder for industrial processing.
Lanthanum-Praseodymium-Neodymium Carbonate Mix
Industrial-grade mixture of rare-earth carbonates (La >50%, with Pr and Nd) used in manufacturing permanent magnets and ceramics, meeting Chapter 28 definitions for rare-earth compounds. Classified under HTS 2846.90.80.70 due to lanthanum predominance and exclusion from cerium carbonate mixtures. Typically packaged in 25kg drums for chemical processing.
High-Purity Lanthanum-Cerium-Free Carbonate Blend
Refined mixture of lanthanum-rich rare-earth carbonates (no cerium), applied in optical glass polishing and phosphors, chemically defined per Chapter 28 Note 1. HTS 2846.90.80.70 applies as 'other mixtures of rare-earth carbonates' with lanthanum predominant. Supplied as 99%+ purity powder.
Lanthanum-Dominant Didymium Carbonate Mixture
Didymium carbonate blend with lanthanum as chief component (La/Pr/Nd mix), used in glass coloring and decolorizing agents, fitting Chapter 28 inorganic rare-earth compounds. Under HTS 2846.90.80.70 for non-cerium rare-earth carbonate mixtures. White microcrystalline powder.
Industrial Lanthanum-Rich REO Feedstock Carbonate
Lanthanum predominant carbonate mix serving as feedstock for rare-earth oxide (REO) production in catalysts and alloys. Complies with HTS 2846.90.80.70 as other rare-earth carbonate mixtures excluding cerium. Bulk powder for high-volume import.
Lanthanum-Yttrium Hybrid Carbonate Powder
Specialty mixture where lanthanum carbonate exceeds other RE carbonates including yttrium, used in advanced ceramics and electronics. HTS 2846.90.80.70 due to lanthanum predominance in non-cerium mixtures, per legal subheading notes.
Purified Lanthanum-Neodymium Carbonate for Catalysts
Purified blend of La and Nd carbonates (La > Nd) for automotive catalyst precursors, chemically defined rare-earth compound per Chapter notes. Fits HTS 2846.90.80.70 as lanthanum-predominant non-cerium carbonate mixture.
