HTS US: 2826.XX.XXXX
Description
This heading includes a range of fluorine-containing chemical compounds primarily used in industrial applications such as aluminum production, chemical manufacturing, and specialized inorganic processes. The chapter covers:
- Fluorides: Simple salts where fluorine is combined with metals such as aluminum, ammonium, and sodium.
- Fluorosilicates and Fluoroaluminates: More complex salts involving silicon and aluminum with fluorine.
- Other Complex Fluorine Salts: Various synthetic or naturally derived compounds including synthetic cryolite and lithium hexafluorophosphate.
These substances are important as fluxes, catalysts, and intermediates in chemical industries.
