Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cerium carbonate is included in the mixture
Mixtures containing cerium carbonate shift to 2846.10, the specific subheading for cerium compounds before 'other' categories.
If processed into rare-earth chlorides instead of carbonates
Chlorides, oxychlorides, and fluorides of rare-earths fall under 2827, changing classification based on anion per Chapter 28 structure.
If supplied as a catalyst preparation for industrial use
Rare-earth carbonate mixtures formulated as supported catalysts become 'catalytic preparations' in 3815, not pure compounds.

Import Tips & Compliance
• Declare exact oxide equivalent (REO) content on commercial invoice, as buyers often specify purity levels for magnet production
• Comply with US Rare Earth Element import tracking; retain supplier affidavits confirming no cerium content to match subheading
• Watch for anti-dumping duties on Chinese origins; use HTS lookup tools and consult CBP for binding rulings on mixtures
