HS-4 · Heading
2923 — Quaternary ammonium salts and hydroxides; lecithins and other phosphoaminolipids, whether or not chemically defined
Chapter 29: Organic chemicals
Plain-language overview
Use HS-4 2923 when importing or exporting quaternary ammonium salts, such as choline salts, or lecithins. For example, if you are shipping a product containing choline chloride for use in animal feed, this code is applicable.
When deciding between the HS-6 lines under this heading, consider whether your product is a specific quaternary ammonium salt or a lecithin. For instance, HS-6 292310 is for choline and its salts, while HS-6 292320 covers lecithins, which are often used in food products.
If your product includes specialized quaternary ammonium compounds like tetraethylammonium perfluorooctane sulphonate, you should use HS-6 292330. In contrast, HS-6 292340 is designated for didecyldimethylammonium perfluorooctane sulphonate, which has distinct applications in industrial cleaning.
For any quaternary ammonium salts or hydroxides not specifically defined in the previous lines, HS-6 292390 is the catch-all category. This is useful if your product doesn’t fit neatly into the other classifications.
