HS Code for Nitrogen fertilizer blend

Nitrogen fertilizer blends consisting of double salts and mixtures of calcium nitrate and ammonium nitrate are classified under HS code 3102.60. This classification is governed by the General Rules of Interpretation (GRI) 1 and 6, as well as the specific notes for Chapter 31 of the Harmonized System. Heading 3102 specifically covers mineral or chemical fertilizers that are nitrogenous. Subheading 3102.60 is a specific provision for the double salts and mixtures of calcium nitrate and ammonium nitrate. The classification is determined by the chemical composition of the product; for a fertilizer to fall under this code, it must primarily provide nitrogen as a nutrient and specifically contain these two salts in a combined or mixed state. This classification remains applicable regardless of whether the product is intended for direct soil application or for use in fertigation systems, provided it meets the chemical criteria defined in the HS nomenclature. The presence of calcium in this mixture serves as a secondary nutrient, but the primary classification remains under nitrogenous fertilizers because the ammonium nitrate component is the dominant source of nitrogen.

Products Included

• Calcium ammonium nitrate (CAN) mixtures
• Double salts of calcium nitrate and ammonium nitrate
• Granulated nitrogenous fertilizers containing calcium and ammonium salts
• Blended mineral fertilizers where the nitrogen source is exclusively calcium-ammonium nitrate double salts

Common Misclassification

This product is frequently misclassified under HS code 3102.10, which is reserved for Urea, or HS code 3102.30, which covers pure ammonium nitrate. Another common error is classifying these blends under HS code 3105.20 if the exporter mistakenly believes the calcium content qualifies it as a multi-nutrient fertilizer (NPK). However, calcium is not considered one of the three primary fertilizing elements (nitrogen, phosphorus, potassium) for the purposes of heading 3105. Furthermore, if the mixture contains any amount of phosphorus or potassium, it must be moved to heading 3105 entirely.

FAQ

What is the HS code for nitrogen fertilizer blend?
