HTS US: 2832.XX.XXXX
Description
Heading 2832 encompasses sulfites and thiosulfates, which are chemical compounds widely used in industries such as food preservation, water treatment, and photographic processing. These substances are primarily salts derived from sulfurous acid and serve as antioxidants, preservatives, and reducing agents.
The classification divides these compounds into sodium sulfites, other sulfites, and thiosulfates, each with specific chemical compositions and applications:
- Sodium sulfites: Commonly used as preservatives and antioxidants in food and beverages.
- Other sulfites: Includes sulfite salts of other metals beyond sodium.
- Thiosulfates: Salts containing thiosulfate ions, frequently used in photographic fixing and water treatment.

Detailed Breakdown of Subheadings
The 4-digit HS heading 2832 is divided into specific subheadings by the type of sulfite or thiosulfate compound. Below is a full table outlining the 10-digit US HTS codes along with descriptions:
| HS/HTS Code | Description |
|---|---|
| 2832.10.00.00 | Sodium sulfites |
| 2832.20.00.00 | Other sulfites (non-sodium) |
| 2832.30.10.00 | Sodium thiosulfate |
| 2832.30.50.00 | Other thiosulfates |
What is NOT Classified Here?
To avoid improper classification, it is important to note what this heading excludes:
- Sulfite-based organic compounds or complex mixtures that fall under other chemical headings.
- Other sulfur-containing salts such as sulfates and sulfonates, which are classified elsewhere.
- Prepared chemical mixtures or formulations that include sulfites but are not primarily sulfite or thiosulfate compounds.
Notes
- Regulatory Considerations: Import of sulfites and thiosulfates may be subject to chemical safety regulations depending on the country and intended use.
- Customs Duty Rates: Duty rates depend on the exact 10-digit code and country of origin; chemical compounds often have specific tariffs or exemptions.
- Packaging and Labeling: Proper labeling and safety data sheets are required for import/export due to their chemical nature.
