Lanthanum-Yttrium Rare Earth Carbonate Mixture
A chemically defined mixture of lanthanum and yttrium carbonates, excluding cerium, used primarily in the production of phosphors for lighting and displays. This falls under HTS 2846.90.80.75 as a mixture of rare-earth carbonates other than cerium carbonate, classified in Chapter 28 for inorganic compounds of rare-earth metals. It meets the criteria for chemically defined compounds per subheading note to 2852.10, but is specifically covered here.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If separated into individual rare-earth carbonates
Individual rare-earth carbonates (e.g., pure lanthanum carbonate) fall under heading 2836 for carbonates of inorganic bases, not mixtures.
If not chemically defined or mixed with organic stabilizers
Mixtures lacking chemical definition or with additives become 'other chemical preparations' in 3824, per Chapter 28 exclusions for organo-inorganic compounds.
If broader 'other' rare-earth compounds without carbonate specification
If the mixture doesn't qualify strictly as carbonates, it shifts to the parent 'other' subheading for rare-earth compounds.

Import Tips & Compliance
• Verify chemical purity and composition via lab analysis to confirm it qualifies as a 'chemically defined' mixture under Chapter 28 notes
• Include certificates of analysis (COA) and safety data sheets (SDS) in documentation, as rare-earth compounds may trigger REACH-like regulations or TSCA reporting
• Avoid misclassification as finished phosphors (3206); ensure import as bulk chemical precursor to prevent duty pitfalls
