HS Code for Nitrogen fertilizer (ammonium nitrate)

Ammonium nitrate fertilizer is classified under HS code 3102.30. Chapter 31 of the Harmonized System is dedicated to fertilizers, and heading 3102 specifically covers mineral or chemical fertilizers that are nitrogenous. Subheading 3102.30 is the specific designation for ammonium nitrate, whether or not it is in an aqueous solution. This classification is used for products intended for soil application to provide nitrogen to plants. The classification remains consistent regardless of whether the ammonium nitrate is in a solid prilled form or a liquid solution, provided it is not mixed with other fertilizing elements like phosphorus or potassium in a way that would move it to heading 3105. The purity and the specific chemical identity as ammonium nitrate are the primary drivers for this classification under GRI 1. This code is essential for monitoring the trade of substances that are both vital for agriculture and subject to strict security regulations due to their potential use in explosives.

Products Included

• Pure ammonium nitrate in prilled or granular form
• Ammonium nitrate in aqueous solution for agricultural use
• High-nitrogen mineral fertilizers consisting of ammonium nitrate

Common Misclassification

Ammonium nitrate (3102.30) is often confused with 3102.40, which covers mixtures of ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances. This is a critical distinction for safety regulations and tariff application. Another frequent error is classifying it under 3105.20 if it is part of a multi-nutrient (NPK) fertilizer; heading 3105 is reserved for fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Furthermore, if the product is not intended for fertilizer use, it might be mistakenly placed in Chapter 28, though Chapter 31 usually takes precedence for this chemical.
