HTS US: 2834.XX.XXXX
Description
This heading covers chemical compounds classified as nitrites and nitrates. These substances are salts or esters of nitrous acid and nitric acid respectively, widely used in various industrial, agricultural, and chemical applications. The classification includes:
- Nitrites: Compounds containing the nitrite ion (NO2–), commonly used as preservatives, in chemical syntheses, or as intermediates in manufacturing.
- Nitrates: Compounds containing the nitrate ion (NO3–), frequently used as fertilizers, explosives, and in food preservation.
The heading breaks down these substances by their metal or element association such as sodium, potassium, bismuth, calcium, and strontium.

Detailed Breakdown of Subheadings
The 4-digit heading 2834 is subdivided into nitrites and nitrates based on the associated metal or element as shown below:
| HTS Code | Description | Examples & Notes |
|---|---|---|
| 2834.10 | Nitrites: | Compounds containing the nitrite ion with specified metals. |
| 2834.10.10.00 | Of sodium | Sodium nitrite, extensively used in food preservation and chemical manufacturing. |
| 2834.10.50.00 | Other nitrites | Includes nitrites of metals other than sodium, used in various industrial applications. |
| 2834.21.00.00 | Of potassium | Potassium nitrite, used in fertilizers and chemical industries. |
| 2834.29 | Other nitrates and nitrites: | Nitrates or nitrites of less common metals or elements. |
| 2834.29.05.00 | Of bismuth | Bismuth nitrate or nitrite, used in pharmaceuticals and specialty chemicals. |
| 2834.29.10.00 | Of calcium | Calcium nitrate, commonly used as a fertilizer and in wastewater treatment. |
| 2834.29.20.00 | Of strontium | Strontium nitrate, often used in pyrotechnics and flares. |
| 2834.29.51.00 | Other nitrates or nitrites | Miscellaneous nitrates and nitrites not otherwise specified. |
What is NOT Classified Here?
To avoid misclassification, note these exclusions:
- Organic nitrates or nitrites and related esters are classified under different headings within organic chemicals.
- Compounds where nitrates or nitrites are part of complex formulations or mixtures may fall under other headings depending on the product composition.
- Explosives containing nitrates are classified under Chapter 36.
Notes
- Regulatory Compliance: Import and export of nitrites and nitrates are subject to chemical safety regulations due to their reactive and sometimes hazardous nature.
- Duty Rates: Tariffs can vary based on the specific compound and country of origin; consult the latest USHTS for precise rates.
- Usage Restrictions: Certain nitrates and nitrites may be regulated under environmental or health laws, requiring permits or certifications.
