HTS US: 2837.XX.XXXX
Description
HTS Code 2837 encompasses a group of chemical substances known primarily as cyanides, cyanide oxides, and complex cyanides. These compounds are widely utilized in industries such as mining, electroplating, chemical synthesis, and pharmaceuticals due to their chemical properties.
The heading includes:
- Simple cyanides: These are salts containing the cyanide ion, such as sodium cyanide, potassium cyanide, and calcium cyanide.
- Cyanide oxides: Though less common, these oxides are related compounds often grouped here for classification purposes.
- Complex cyanides: Compounds where cyanide ions are coordinated with metal ions forming complex salts like potassium ferricyanide.
These substances are generally hazardous and require careful handling and regulation in international trade.

Detailed Breakdown of Subheadings
The heading 2837 is broken down into subheadings based on the chemical composition and type of cyanide compound:
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2837.11.00.00 | Of sodium | Primarily sodium cyanide, widely used in gold mining and electroplating. |
| 2837.19.01 | Other | Includes various cyanides not classified elsewhere under 2837.11 or 2837.20. |
2837.19.01.10 |
Potassium cyanide | Highly toxic salt used in chemical synthesis and metal processing. |
2837.19.01.15 |
Calcium cyanide | Used mainly in mining and as a fumigant. |
2837.19.01.25 |
Other | Miscellaneous cyanides not specified above. |
| 2837.20 | Complex cyanides: | Compounds where cyanide ions are complexed with metals. |
2837.20.10.00 |
Potassium ferricyanide | A common complex cyanide used in photography, blueprinting, and as an analytical reagent. |
2837.20.51.00 |
Other | Other complex cyanide compounds not specifically listed. |
What is NOT Classified Here?
To avoid misclassification, the following are excluded:
- Cyanogen and cyanogen halides – classified separately under other headings.
- Organic cyanides (nitriles) – typically classified under organic chemical chapters.
- Compounds with cyanide functional groups bonded differently that do not form simple cyanide or complex cyanide salts.
Notes
- Hazardous Material Handling: Many cyanides are highly toxic and subject to strict regulations regarding import, export, storage, and transportation.
- Duty Rates: Duty and tariff rates depend on the specific 10-digit HTS code and importing country regulations; certain cyanides may be subject to trade restrictions or require special permits.
- Regulatory Compliance: Importers must comply with chemical safety standards, including documentation and labeling under agencies like OSHA, EPA, and equivalents in other countries.
