HS Code for Ammonium nitrate

Ammonium nitrate (NH4NO3) is classified under HS code 2834.29 when it is presented as a separate chemically defined compound for industrial or laboratory use. Heading 2834 covers nitrites and nitrates. The subheading 2834.29 is a residual category for nitrates other than those of potassium (which are 2834.21). The classification logic follows the General Rules for the Interpretation (GRI) of the Harmonized System, identifying the product by its chemical composition as an inorganic salt of nitric acid. It is critical to distinguish between the pure chemical form and the agricultural grade. While Chapter 28 covers separate chemically defined compounds, Chapter 31 covers fertilizers. Therefore, if ammonium nitrate is prepared specifically for use as a fertilizer, or if it is presented in tablets or similar forms or in packages of a gross weight not exceeding 10 kg, it would shift to heading 3102. However, for laboratory reagents, explosives manufacturing precursors, and general industrial applications where the substance is a pure chemical, 2834.29 is the appropriate designation. The substance is highly regulated globally due to its oxidizing properties and its potential use in the manufacture of explosives, making accurate HS code declaration vital for customs compliance and safety protocols.

Products Included

• Chemically pure ammonium nitrate
• Analytical reagent grade ammonium nitrate
• Industrial grade ammonium nitrate (non-fertilizer)
• Ammonium nitrate solutions (aqueous)
• Ammonium nitrate crystals for industrial use

Common Misclassification

The most frequent misclassification occurs with HS code 3102.30, which is specifically for ammonium nitrate used as a fertilizer. Importers must determine the end-use and purity to choose between 2834.29 and 3102.30. Another common error involves HS code 3602.00, which covers prepared explosives. While ammonium nitrate is a major component of explosives like ANFO, the pure chemical itself remains in Chapter 28 unless it has been mixed with fuel oil or other sensitizers to become a prepared explosive.

FAQ

What is the HS code for Ammonium nitrate?

The HS code for pure or industrial ammonium nitrate is 2834.29. If it is intended for use as a fertilizer, the code is 3102.30.

Does the concentration of the solution affect the HS code?

Generally, aqueous solutions of ammonium nitrate remain under 2834.29 as long as they are not specifically formulated as liquid fertilizers, which would fall under 3102.
