Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ground into powder for immediate flux use
Mechanically processed fluoride powders are classified as inorganic chemicals rather than crude minerals.
If Chapter notes prioritize mixtures classifiable in heading 2517 over 2530.
If for use in radioactive processing applications
Salts of specific elements for nuclear uses fall under Chapter 28 salts.

Import Tips & Compliance
• Include mining origin documentation, as Greenland cryolite has unique geological certification requirements
• Test for radioactive impurities common in some deposits to meet U.S. import safety standards
• Avoid common error of declaring as 'refined flux' which shifts classification to Chapter 38
