HTS US: 2923.XX.XXXX
Description
Heading 2923 encompasses a variety of chemical substances primarily consisting of quaternary ammonium salts and hydroxides as well as lecithins and other phosphoaminolipids. These compounds may be chemically defined or undefined in structure. The substances under this heading have diverse applications ranging from pharmaceutical uses to organic certifications.
The key groups included are:
- Choline and its salts: Vital components often used in nutrition and biochemistry.
- Lecithins and other phosphoaminolipids: Important phospholipids used in food, pharmaceuticals, and cosmetics. This group includes purified egg phospholipids meeting FDA pharmaceutical standards and certified organic lecithins.
- Specific quaternary ammonium salts: Such as tetraethylammonium perfluorooctane sulfonate and didecylmethylammonium perfluorooctane sulfonate, often used in industrial and chemical applications.
Code Hierarchy
- Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)
- Chapter 29: Organic Chemicals
- Heading 2923: Quaternary ammonium salts and hydroxides; lecithins and other phosphoaminolipids, whether or not chemically defined.
- US HTS Code (10-digit):
2923.XX.XXXX– The final digits specify the exact chemical substance or group.
Detailed Breakdown of Subheadings
The 4-digit HS heading 2923 is subdivided into more specific 6-digit and 10-digit codes that identify the exact substances within the category.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2923.10.00.00 | Choline and its salts | Includes pure choline compounds used in dietary supplements and biochemical research. |
| 2923.20 | Lecithins and other phosphoaminolipids: | Phospholipids important in food technology, pharmaceuticals, and nutrition. |
| 2923.20.10.00 | Purified egg phospholipids, pharmaceutical grade meeting requirements of the U.S. Food and Drug Administration, for use in intravenous fat emulsion | Specialized lecithins used in medical applications requiring strict purity standards. |
| 2923.20.20 | Other | General category for lecithins not otherwise specified. |
| 2923.20.20.10 | Certified organic lecithins | Lecithins produced under certified organic standards for use in organic foods and cosmetics. |
| 2923.20.20.50 | Other | Non-organic lecithins and phosphoaminolipids not otherwise classified. |
| 2923.30.00.00 | Tetraethylammonium perfluorooctane sulfonate | Chemical used in specialized industrial and laboratory processes. |
| 2923.40.00.00 | Didecylmethylammonium perfluorooctane sulfonate | Another specialized quaternary ammonium compound for industrial use. |
| 2923.90.01.00 | Other | Catch-all category for other quaternary ammonium salts and hydroxides not specifically listed. |
What is NOT Classified Here?
To ensure accurate classification, the following items are excluded from this heading:
- Non-quaternary ammonium compounds: Chemicals that do not contain the quaternary ammonium structure fall under different chapters.
- Phospholipids other than lecithins and phosphoaminolipids: Other types of phospholipids are classified elsewhere.
- Complex mixtures: Preparations or mixtures containing these substances but mainly consisting of other materials may be classified differently.
Notes
- Regulatory Considerations: Some substances under this heading, like pharmaceutical-grade lecithins, must comply with FDA regulations and standards.
- Duties and Tariffs: Duty rates vary by specific 10-digit code depending on chemical composition and intended use.
- Organic Certification: Certified organic lecithins must meet recognized organic production standards to qualify under the respective subheading.
