2923.10.00.00 - Choline and its salts

This HTS category, 2923.10.00.00, specifically covers choline and its various salts. Choline is an essential nutrient that plays a vital role in numerous biological functions, including neurotransmitter synthesis and cell membrane structure. It is typically found and classified in this heading as a pure chemical compound or in salt forms such as choline chloride, choline bitartrate, or choline citrate. These products are often used in pharmaceuticals, nutritional supplements, and animal feed.

This classification is distinct from its siblings within heading 2923. While 2923.20 addresses lecithins and other phosphoaminolipids, and 2923.30 and 2923.40 cover specific quaternary ammonium perfluorooctane sulfonates, 2923.10.00.00 is narrowly defined for choline and its direct salt derivatives. The remaining "Other" category, 2923.90.01.00, is reserved for quaternary ammonium salts and hydroxides not otherwise specified.

As this is a leaf node, there are no further subcategories to introduce. Classification within 2923.10.00.00 is determined by the chemical identity of the product as choline or one of its salts. Exporters and importers should ensure that the documentation accurately reflects the chemical composition to facilitate correct classification and customs clearance.
