About heading 2826
Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts
Heading 2826 covers inorganic fluorine salts: fluorides, fluorosilicates, fluoroaluminates and other complex fluorine salts. It is split first by type, with a separate line for aluminum fluoride, a group for other fluorides divided by cation (ammonium, sodium, other), a line for synthetic cryolite, and a residual group for fluorosilicates and other complex salts. Most lines carry low or free general (MFN) rates.
