HS Code for UAN fertilizer

UAN (Urea Ammonium Nitrate) fertilizer is classified under HS code 3102.80. This classification is governed by Chapter 31 of the Harmonized System, which covers fertilizers. Heading 3102 is dedicated to nitrogenous mineral or chemical fertilizers. Subheading 3102.80 specifically addresses mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution. This product is a liquid fertilizer typically containing between 28% and 32% nitrogen. The classification is precise because the product is a chemical mixture of two nitrogen sources (urea and ammonium nitrate) stabilized in water. Because it is a specific chemical mixture defined by the HS nomenclature, it takes precedence over more general nitrogenous fertilizer codes.

Products Included

• UAN 28 (28% Nitrogen solution)
• UAN 30 (30% Nitrogen solution)
• UAN 32 (32% Nitrogen solution)
• Aqueous solutions of urea and ammonium nitrate
• Ammoniacal solutions of urea and ammonium nitrate

Common Misclassification

UAN is often misclassified under HS code 3102.10 (pure urea) or HS code 3102.30 (pure ammonium nitrate). However, because UAN is a mixture of both, those codes are incorrect. It is also sometimes confused with HS code 3105, which is for fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Since UAN only contains nitrogen, it must remain in 3102.

FAQ

What is the HS code for UAN fertilizer?

The specific HS code for Urea Ammonium Nitrate (UAN) in aqueous or ammoniacal solution is 3102.80.

Does the nitrogen concentration change the HS code?

No, whether the solution is UAN 28, 30, or 32, it remains under HS code 3102.80 as long as it is a mixture of urea and ammonium nitrate in solution.
