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.

Frequently asked questions

What is the HTS code for choline chloride?

Choline and its salts are classified in 2923.10.00.00. The general (MFN) rate for that line is 3.7%.

What is the duty on lecithin?

Other lecithins enter under 2923.20.20.50 at a general (MFN) rate of 5%, and certified organic lecithins under 2923.20.20.10 also at 5%. Purified egg phospholipids of pharmaceutical grade for intravenous fat emulsion go in 2923.20.10.00, which is Free.

How do I classify a quaternary ammonium salt that is not choline or a named perfluorooctane sulfonate?
