About heading 2923

Quaternary ammonium salts and hydroxides; lecithins and other phosphoaminolipids, whether or not chemically defined

Heading 2923 covers quaternary ammonium salts and hydroxides, plus lecithins and other phosphoaminolipids, whether or not chemically defined. It splits first by product family: choline and its salts, lecithins and phosphoaminolipids, two named perfluorooctane sulfonate quaternary ammonium salts, and a residual other group. The lecithin group is further split by pharmaceutical grade and organic status.
