Cerium Fluoride (CeF3) Crystals
Cerium Fluoride (CeF3) Crystals are synthetic crystals used in optical coatings and laser components. They are classified under tariff item 2846.10.00 as an inorganic compound of cerium, distinct from alkali fluorides per Chapter 28 notes. The crystals are chemically defined and not excluded by Chapter 28 note 3, as they are not optical elements of Chapter 90.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the crystals are finished optical elements
Optical elements of any material are classified in Chapter 90.
If the product is a mixed rare-earth fluoride rather than pure cerium fluoride
Compounds of mixtures of rare-earth metals fall under the 'other' subheading.

Import Tips & Compliance
• Confirm the crystals are not cut or shaped as optical elements, which would move them to Chapter 90
• Declare the chemical purity and crystalline form on the commercial invoice
• If the crystals are doped for laser use, ensure the doping does not introduce organic components that could affect classification
