HS Code for Nitrate phosphate fertilizer

Nitrate phosphate fertilizer is classified under HS code 3105.51. This classification is found within Chapter 31, which is dedicated to fertilizers. Heading 31.05 covers mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium; other fertilizers; and goods of this chapter in tablets or similar forms or in packages of a gross weight not exceeding 10 kg. Subheading 3105.51 specifically addresses those fertilizers that contain both nitrates and phosphates. These are binary fertilizers (NP) that provide two primary nutrients. The classification is determined by the chemical composition of the mixture. This code includes mixtures of ammonium nitrate with calcium phosphates or other phosphate-bearing minerals intended for soil enrichment. The Harmonized System notes for Chapter 31 specify that heading 31.05 includes only fertilizers of a kind used as such and containing, as essential constituents, at least one of the fertilizing elements. For 3105.51, the presence of both nitrogen (in nitrate form) and phosphorus (in phosphate form) is the defining characteristic. This classification is critical for trade statistics and the application of agricultural tariffs and subsidies.

Products Included

Common Misclassification

Nitrate phosphate fertilizer is often misclassified under 3102.30, which is for ammonium nitrate alone. However, if phosphates are added, it must move to 3105. Another common error is using 3105.20, which is for NPK fertilizers. If the mixture contains any amount of potassium, 3105.20 takes precedence over 3105.51. Additionally, pure ammonium phosphate without nitrates would be classified under 3105.40.
