Lanthanum-Yttrium Rare Earth Carbonate Mixture from China
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.

Import Tips
• 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
