Aluminum Fluosilicate (Al2(SiF6)3) from Mexico

Aluminum fluosilicate (Al2(SiF6)3) is a complex fluorine salt of aluminum, used as a laundry sour and in water fluoridation. Although it contains silicon, it is a fluosilicate, which falls under the subheading 'fluorosilicates, fluoroaluminates and other complex fluorine salts' (2826.90) rather than 2826.12.00, which covers only simple fluorides of aluminum. Therefore, it does not belong under this tariff item.
