Product classification
HS code for Calcium ammonium nitrate: 3102.40
Fertilizers, mineral or chemical, ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances, mixtures thereof.
Classification of calcium ammonium nitrate under HS 3102.40
Calcium ammonium nitrate (CAN) is classified under HS code 310240, which specifically covers "Fertilizers, mineral or chemical; ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances, mixtures thereof." This classification is part of Chapter 31, dedicated to fertilizers, and precisely identifies mixtures where ammonium nitrate is combined with non-fertilizing inorganic substances, most commonly calcium carbonate. CAN is a prime example, valued for its dual nitrogen and calcium content, which provides essential nutrients to plants, and its reduced explosivity compared to pure ammonium nitrate. The code ensures that this specific type of compound fertilizer, designed for agricultural use, is accurately categorized for international trade and regulatory compliance.

Codes often confused with 3102.40
Common mistake. Common misclassifications for Calcium Ammonium Nitrate (CAN) often involve pure ammonium nitrate or other nitrogenous fertilizers. HS code 310230 covers "Ammonium nitrate, whether or not in aqueous solution," which is for pure ammonium nitrate without the addition of calcium carbonate or other non-fertilizing substances. The key distinction is the presence of these inorganic non-fertilizing substances in 310240, which modifies the properties of the ammonium nitrate. Another potential confusion arises with HS code 310290, which covers "Other mineral or chemical fertilizers, nitrogenous, including mixtures not specified elsewhere." While CAN is a nitrogenous fertilizer mixture, 310290 is a residual category for mixtures not specifically described elsewhere. Since 310240 precisely describes ammonium nitrate with calcium carbonate, it takes precedence. Additionally, chemical nitrates not primarily intended for use as fertilizers, such as those under Chapter 28 (e.g., 283429 for other nitrates), would be incorrectly applied, as 310240 specifically targets fertilizer applications.
Top exporters and importers of HS 310240 (the code used for calcium ammonium nitrate), 2025
In 2025, the largest exporter of HS 310240 (the code used for calcium ammonium nitrate) in UN Comtrade data was the Netherlands, with 22% of world exports; the largest importer in UN Comtrade data was Germany, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 310240, not only calcium ammonium nitrate.

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 calcium ammonium nitrate
What is the HS code for Calcium ammonium nitrate?
The HS code for Calcium ammonium nitrate is 310240 (Fertilizers, mineral or chemical; ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances, mixtures thereof). The HS code for Calcium ammonium nitrate is 310240. This code specifically covers mineral or chemical fertilizers consisting of ammonium nitrate mixed with calcium carbonate or other inorganic non-fertilizing substances.
How do I classify Calcium ammonium nitrate for customs?
Calcium ammonium nitrate is classified under HS code 310240 — Fertilizers, mineral or chemical; ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances, mixtures thereof. This is a 6-digit subheading level code.
Why is pure ammonium nitrate classified differently from Calcium Ammonium Nitrate?
Pure ammonium nitrate is classified under HS code 310230. Calcium Ammonium Nitrate (310240) is classified differently because it is a specific mixture of ammonium nitrate with calcium carbonate or other non-fertilizing inorganic substances, which alters its chemical composition, properties, and safety profile compared to the pure compound.
Which countries are the top exporters of calcium ammonium nitrate (HS 310240)?
In 2025, the top exporters of HS 310240 (the code used for calcium ammonium nitrate) in UN Comtrade data were the Netherlands ($622M, 22% of world exports), Belgium ($440M) and Germany ($310M). World exports came to about $2.8B, 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.
