HS Code for Urea fertilizer

Urea fertilizer is classified under HS code 310210 because it is a nitrogenous mineral or chemical fertilizer. According to the General Rules of Interpretation (GRI) and the Chapter 31 notes of the Harmonized System, urea is specifically identified by its chemical composition as a diamide of carbonic acid. When intended for use as a fertilizer, whether or not it is in an aqueous solution, it falls under this specific subheading. The classification is determined by the product's primary function as a soil nutrient provider and its high nitrogen content, typically around 46%. Even if the urea is of technical grade, if it is not put up in specific forms or packings as described in heading 3105, it remains under 310210. The purity of the product does not generally move it out of Chapter 31 unless it is specifically prepared as a reagent or for non-agricultural chemical synthesis in a way that meets other chapter definitions.

Products Included

• Prilled urea for agricultural application
• Granular urea fertilizers
• Urea in aqueous solution (liquid fertilizer)
• Technical grade urea used as a nitrogen source in farming
• Coated urea (e.g., sulfur-coated) intended for slow release

Common Misclassification

Urea fertilizer is frequently confused with HS code 390910, which covers urea resins and amino-resins in primary forms. While both contain urea, 390910 is for plastic polymers and adhesives. Another common error is using HS code 3105, which is reserved for fertilizers containing two or three of the fertilizing elements (nitrogen, phosphorus, and potassium). If urea is mixed with phosphates or potash, it must be moved to 3105. Additionally, pure urea used as a laboratory reagent might sometimes be incorrectly filed under Chapter 29 (Organic Chemicals), but the HS nomenclature specifically directs most urea to 3102.

FAQ

What is the HS code for Urea fertilizer?

The primary HS code for urea fertilizer is 310210, which covers mineral or chemical nitrogenous fertilizers.

Is liquid urea classified differently than solid urea?

No, HS code 310210 specifically includes urea whether or not it is in an aqueous solution, meaning both liquid and solid forms share the same code.
