Diethylammonium Perfluorooctane Sulfonate
Diethylammonium perfluorooctane sulfonate is a salt of diethylamine and perfluorooctanesulfonic acid. Although the tariff item specifically names diethanolammonium perfluorooctane sulphonate, this product is chemically analogous as an amino-alcohol salt with a perfluoroalkyl chain. It is classified under heading 29.22 as an oxygen-function amino-compound, specifically as a salt of an amino-alcohol.
