HTS Code: 2808 — Nitric Acid and Sulfonitric Acids

This heading encompasses nitric acid and sulfonitric acids, which are highly important inorganic acids widely used in chemical manufacturing, explosives, fertilizers, and other industrial processes.

• Nitric Acid: A strong mineral acid with the formula HNO₃, commonly used as a reagent in the production of fertilizers, explosives, and in metal processing.
• Sulfonitric Acids: Compounds that combine sulfonic acid and nitric acid groups, used in specialized chemical synthesis and manufacturing.

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 2808: Nitric acid; sulfonitric acids.
• US HTS Code (10-digit): 2808.00.00.00 – The full code specifies the exact compound, either nitric acid or sulfonitric acids.

Detailed Breakdown of Subheadings

The 6-digit HS heading 2808 is subdivided into more specific 10-digit HTS codes to differentiate between nitric acid and sulfonitric acids.

What is NOT Classified Here?

To ensure precise classification, note the following exclusions:

• Other inorganic acids such as sulfuric acid, hydrochloric acid, and phosphoric acid are classified under different headings within Chapter 28.
• Organic acids and their salts are classified separately in other chapters.
• Mixtures or solutions containing nitric acid but primarily composed of other substances may fall under different classifications depending on composition.

Notes

• Import Regulations: Nitric acid and sulfonitric acids are subject to regulations due to their potential use in explosives manufacturing. Importers must comply with relevant chemical safety and security laws.
• Duty Rates: Duty rates vary by subheading and country of origin. Chemical imports often attract specific tariffs and may require licensing.
• Handling and Safety: Due to their corrosive and reactive nature, these acids require special handling, packaging, and transport compliance.
