Use it to classify these goods and to find who trades them.
Goods answering to “Quaternary ammonium salts and hydroxides; lecithins and other phosphoaminolipids, whether or not chemically defined” split into 5 six-digit codes, 292310 through 292390. Each one carries its own customs description, and the exact wording below is what a classification has to match. The heading is number 23 of 42 in Chapter 29, Organic chemicals, which runs to 410 six-digit codes in all.
Six-digit codes under heading 2923
| HS Code | Import–export description |
|---|---|
| 292310 | Quaternary ammonium salts and hydroxides; choline and its salts, whether or not chemically defined |

| 292330 | Quaternary ammonium salts and hydroxides; tetraethylammonium perfluorooctane sulphonate, whether or not chemically defined |
| 292340 | Quaternary ammonium salts and hydroxides; didecyldimethylammonium perfluorooctane sulphonate, whether or not chemically defined |

What HS code 2923 covers
This heading groups two kinds of organic chemicals. The first kind is quaternary ammonium salts and hydroxides. People often call them quats or quaternary ammonium compounds. The second kind is lecithins and other phosphoaminolipids. These are fatty substances that contain phosphorus and nitrogen. Either kind can be chemically defined or not.
The heading belongs to organic chemicals, chapter 29 of the Harmonized System. You may also see it written as HSN code 2923 or HTS code 2923. The name changes from country to country, but the first digits stay the same.
Here is how the digits work. 2923 is the four-digit heading. The six-digit subheadings under it are shared by customs offices around the world. A country can add more digits after those six in its own tariff, so a local code may be longer. Duty and tax rates follow those national extensions, so check the tariff of the country you ship to. If you are unsure which code fits your product, try the HS code classifier.
How to choose the right 2923 subheading
Start with the exact name of your product. Then go down the list in order. Use the catch-all code last. Here is what each code means in plain words.
Lecithin is the easy one. The two sulphonate codes are narrow. They are only for the two named salts. A different quaternary ammonium salt does not belong there, even if it looks similar.
- 292310: choline and its salts
- 292320: lecithins and other phosphoaminolipids
- 292330: tetraethylammonium perfluorooctane sulphonate only
- 292340: didecyldimethylammonium perfluorooctane sulphonate only
- 292390: any other quaternary ammonium salt or hydroxide not named above
HS 2923 vs nearby headings
Many nitrogen compounds sit close to 2923, so mix-ups are common. The key question is the chemical group in the molecule.
Heading 2922 is for amino-compounds that also have an oxygen function. Heading 2929 is a residual heading for other nitrogen-function compounds in the chapter. A quaternary ammonium salt has a nitrogen atom that carries a positive charge and is bonded to four carbon groups. That is the feature that points you to 2923 rather than to 2921.
If your goods match more than one heading, read the legal text of each heading and the chapter notes before you decide.
HS code 2923 import and export data: find buyers and suppliers
A correct code is the key to searching customs data. Once you know your six-digit code, you can look for the companies that move that product across borders. This works for quaternary ammonium salts, choline and lecithin alike.

HS Code 2923: common questions
What is the HS code for choline and its salts?
This applies whether or not the product is chemically defined.
What is the lecithin HS code?
The code covers them whether or not they are chemically defined.
What falls under HS code 292390?
The letters n.e.c. mean not elsewhere classified.
What is the difference between HS 2921 and 2923?
Heading 2921 covers amine-function compounds. Heading 2923 covers quaternary ammonium salts and hydroxides, where the nitrogen atom carries a positive charge, and also lecithins.
What is the difference between a four-digit and a six-digit HS code?
The four-digit code is the heading, such as 2923. The six-digit code is a subheading inside it, such as 292320. Countries often add more digits to the six for their own tariffs.
