HTS US: 2806.XX.XXXX
Description
This heading includes important inorganic acids used widely across chemical manufacturing, pharmaceuticals, and industrial processes. Specifically, it covers:
- Hydrogen chloride (Hydrochloric acid): A strong, corrosive acid commonly used in chemical synthesis, pH control, and metal processing.
- Chlorosulfuric acid: A highly reactive acid used in sulfonation reactions, manufacture of detergents, and organic synthesis.
Both substances are typically handled as liquids and require careful transportation and storage due to their corrosive nature.
Code Hierarchy
- Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)
- Chapter 28: Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes
- Heading 2806: Hydrogen chloride (Hydrochloric acid); chlorosulfuric acid
- US HTS Code (10-digit):
2806.XX.XXXX– The final digits specify the exact chemical substance.
Detailed Breakdown of Subheadings
The heading 2806 is divided into the following 10-digit subheadings to precisely classify the substances:
| HTS Code | Description | Examples & Notes |
|---|---|---|
| 2806.10.00.00 | Hydrogen chloride (Hydrochloric acid) | Includes all forms of hydrogen chloride, typically aqueous hydrochloric acid solutions used industrially. |
| 2806.20.00.00 | Chlorosulfuric acid | Used as an intermediate in chemical manufacturing, especially in sulfonation and synthesis of organic compounds. |
What is NOT Classified Here?
To prevent misclassification, the following are excluded:
- Other inorganic acids and acid derivatives are classified under different headings (e.g., sulfuric acid under 2807).
- Organic acids such as acetic acid and citric acid fall outside this heading.
- Solutions or mixtures containing these acids but diluted or combined with other substances may be classified elsewhere depending on composition.
Notes
- Safety and Handling: Both hydrogen chloride and chlorosulfuric acid require strict compliance with safety regulations due to their corrosiveness and potential hazards.
- Import Regulations: Importers must ensure documentation complies with environmental and chemical safety standards as enforced by agencies such as the EPA and DOT.
- Tariff Rates: Duty rates vary by country of origin and intended use; consult the latest USHTS for accurate rates.
