Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If including scandium carbonates
Scandium compounds have a dedicated subheading 2846.90.40, pulling mixtures with scandium out of the 'other' carbonate category.
If natural mineral form like bastnasite ore
Natural borates or carbonates (e.g., unrefined rare-earth minerals) fall under Chapter 25, not refined chemicals in Chapter 28.
If adulterated with fillers for retail polishing powders
Admixtures with non-chemical components become 'other preparations' in 3824, excluded from pure compounds by Chapter notes.

Import Tips & Compliance
• Use precise REO assays (e.g
• 99%+ total rare-earth oxides) to support valuation and avoid undervaluation penalties
• For EU/US imports, check for conflict minerals reporting if sourced from certain regions, though rare-earths are exempt from Dodd-Frank
• Bundle with origin certificates; mixtures from China face Section 301 tariffs—calculate accordingly
