Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contaminated or containing additives
Impure mixtures of rare-earth oxides fall under 'other' mixtures rather than pure compounds.
If doped for electronics and cut into wafers
Processed forms like doped discs shift to heading 3818 or chemical preparations per Chapter notes.
If classified as rare-earth carbonate
Carbonates of rare-earths are excluded to heading 2836 per Chapter Note 2.

Import Tips & Compliance
• Verify purity certificate (typically >99.9%) to confirm classification as chemically defined rare-earth oxide per Chapter 28 Note 1
• Provide chemical analysis reports; mislabeling as mixtures can shift to 2846.90.80.00
• Check REACH/ TSCA compliance for environmental handling of rare-earth imports
