HS Code for Calcium ammonium nitrate

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.

Products Included

• Calcium ammonium nitrate (CAN) in granular or prilled form
• Ammonium nitrate mixed with dolomite
• Ammonium nitrate mixed with limestone
• Ammonium nitrate combined with other inorganic non-fertilizing fillers
• Nitrogenous fertilizers where ammonium nitrate is the primary nitrogen source mixed with calcium

Common Misclassification

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.

FAQ

What is the HS code for Calcium ammonium nitrate?

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.

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.
