Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If artificially crushed to uniform granules
Intentionally sized chemical granules classified as inorganic compounds.
If nes mineral granules not cryolite/chiolite
Same heading but different statistical breakout for other minerals.
If formed into refractory shapes
Refractory bricks containing fluorides classified in Chapter 69.

Import Tips & Compliance
• Provide sieve analysis showing natural granule size distribution
• Include fluoride emission safety data sheets for port handling
• Ensure no thermal treatment; calcined material shifts to Chapter 25 other processed minerals
