Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If manufactured into optical elements like lenses
Finished optical elements from fluorides fall under Chapter 90, not raw chemicals.
If radioactive isotopes incorporated
Radioactive compounds, even fluorides, classify in 2844 per chapter notes.

Import Tips & Compliance
• Provide certificates of analysis confirming single chemical compound status per Chapter 28 notes
• Comply with radiation safety regs if for nuclear use; declare optical grade separately
• Watch for reclassification if doped for electronics, moving to 3818
