HS code for Ammonium nitrate: 2834.29

Nitrates, of other than potassium.

Classification of ammonium nitrate under HS 2834.29

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.

Codes often confused with 2834.29

Common mistake. 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.

Top exporters and importers of HS 283429 (the code used for ammonium nitrate), 2025

In 2025, the largest exporter of HS 283429 (the code used for ammonium nitrate) in UN Comtrade data was China, with 29% of world exports; the largest importer in UN Comtrade data was Germany, with 7.2% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about ammonium nitrate

What is the HS code for Ammonium nitrate?

The HS code for Ammonium nitrate is 283429 (Nitrates; of other than potassium). 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.

How do I classify Ammonium nitrate for customs?

Ammonium nitrate is classified under HS code 283429 — Nitrates; of other than potassium. This is a 6-digit subheading level code.

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.

Which countries are the top exporters of ammonium nitrate (HS 283429)?

In 2025, the top exporters of HS 283429 (the code used for ammonium nitrate) in UN Comtrade data were China ($102M, 29% of world exports), Belgium ($38M) and Poland ($26M). World exports came to about $346M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of ammonium nitrate (HS 283429)?

In 2025, the top importers of HS 283429 (the code used for ammonium nitrate) in UN Comtrade data were Germany ($30M, 7.2% of world imports), the United States ($30M) and France ($25M). World imports came to about $418M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Is the HS code for Ammonium nitrate the same in all countries?

The base HS code 283429 for Ammonium nitrate is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.

What is the NCM code for ammonium nitrate in Brazil?

Brazil splits HS 283429 into 4 NCM codes, so the right one for ammonium nitrate depends on the product's details: 2834.29.10 (Calcium nitrate, 16% nitrogen or less), 2834.29.30 (Aluminium nitrate), 2834.29.40 (Lithium nitrate), 2834.29.90 (Other nitrates).
