HS Code for Aqua fortis

Aqua fortis, the historical and commercial name for nitric acid, is classified under HS code 2808.00. This classification is found in Chapter 28, which covers inorganic chemicals, precious metal compounds, and isotopes. Heading 2808 is a specific, single-level heading that encompasses both nitric acid and sulphonitric acids. Nitric acid is a highly corrosive and primary mineral acid. The classification is based on the chemical's molecular identity rather than its intended use. Whether the aqua fortis is used for etching, fertilizer production, or explosives manufacturing, it remains under 2808.00 as long as it is a chemically defined compound. This code also includes sulphonitric acids, which are mixtures of nitric acid and sulfuric acid in various proportions, often used in nitration processes in organic chemistry.

Products Included

• Nitric acid of all concentrations
• Fuming nitric acid
• Red fuming nitric acid (RFNA)
• Sulphonitric acids (mixtures of nitric and sulfuric acid)
• Commercial grade aqua fortis
• Technical grade nitric acid

Common Misclassification

Aqua fortis is occasionally confused with other strong inorganic acids. For instance, hydrochloric acid is classified under 2806.10 and sulfuric acid under 2807.00. Importers must ensure the chemical composition is verified before assignment. Another misclassification occurs with HS code 3824, which covers prepared binders for foundry molds or chemical products and preparations of the chemical or allied industries. However, because nitric acid is a specifically named inorganic acid in Chapter 28, it takes precedence over the general preparations in Chapter 38.
