HS Code for Mineral nitrogen fertilizer

Mineral nitrogen fertilizer is classified under HS code 3102.29. This classification is governed by Chapter 31 of the Harmonized System, which is dedicated to fertilizers. Heading 31.02 specifically covers mineral or chemical fertilizers that are nitrogenous in nature. The subheading 3102.29 is a residual category for nitrogenous fertilizers other than those explicitly listed in the preceding subheadings (such as urea, ammonium sulphate, or ammonium nitrate). This code typically includes double salts and mixtures of ammonium sulfate and ammonium nitrate, or other mineral nitrogenous compounds that do not meet the specific criteria for the more common nitrogen fertilizers. To qualify for this code, the product must be a mineral or chemical product used primarily for its nitrogen content to promote plant growth.

Products Included

• Double salts of ammonium sulfate and ammonium nitrate
• Calcium cyanamide containing more than 25% nitrogen
• Mixtures of ammonium chloride and ammonium sulfate
• Other mineral nitrogenous fertilizers not specified in 3102.10 through 3102.21

Common Misclassification

The most frequent misclassification occurs when a fertilizer contains more than one fertilizing element. If the nitrogen fertilizer is mixed with phosphorus or potassium, it must be classified under heading 31.05 (e.g., NPK fertilizers) rather than 31.02. Additionally, pure ammonium sulphate is classified under 3102.21, and urea is classified under 3102.10. Importers must ensure the chemical composition is strictly nitrogenous and does not fit into the more specific subheadings of 31.02 before using 3102.29.
