HS Code for Nitric acid

Nitric acid is classified under HS code 2808.00. This heading is unique because it covers both nitric acid and sulphonitric acids. Nitric acid (HNO3) is a highly corrosive mineral acid and a powerful oxidizing agent. In the Harmonized System, Chapter 28 deals with inorganic chemicals. Heading 28.08 is a specific heading that does not have further subheadings in the standard international nomenclature, meaning all concentrations of nitric acid, including fuming nitric acid and aqueous solutions, fall under 2808.00. Sulphonitric acids, which are mixtures of nitric acid and sulphuric acid in varying proportions, are also included here. The classification remains consistent regardless of the concentration of the acid, provided it is not mixed with other substances that would change its character to a preparation classified in another chapter. Nitric acid is a vital industrial chemical used in the production of fertilizers (like ammonium nitrate), explosives, and in the etching and cleaning of metals. Because of its hazardous nature, this HS code is often flagged for safety regulations and transport of dangerous goods (ADR/IMDG) requirements during the customs clearance process.

Products Included

• Aqueous nitric acid solutions
• Fuming nitric acid (red or white)
• Sulphonitric acid (mixtures of nitric and sulphuric acid)
• Concentrated nitric acid (e.g., 68% or 98%)
• Technical grade nitric acid

Common Misclassification

Nitric acid is sometimes confused with HS code 2807.00, which is for sulphuric acid and oleum. While they are both strong mineral acids, they are distinct headings. Another misclassification occurs with 3403, which covers metal-treating preparations; if nitric acid is mixed with inhibitors and surfactants for specific industrial cleaning, it may move to Chapter 34. It should also not be confused with nitrous acid, which is classified under 2811.19.

FAQ

What is the HS code for nitric acid?

The HS code for nitric acid and sulphonitric acids is 2808.00.

Is fuming nitric acid classified differently?

No, fuming nitric acid is classified under the same HS code, 2808.00, as standard nitric acid.
