HS Code for Nitrogen fertilizer

The classification of nitrogenous fertilizers under HS code 3102.90 is determined by the chemical composition of the product and its specific exclusion from other more specific subheadings within heading 3102. Heading 3102 is dedicated to mineral or chemical fertilizers that provide nitrogen, a primary nutrient for plant growth. Subheading 3102.90 serves as a residual category for products that do not meet the specific criteria of the preceding subheadings, such as urea (3102.10), ammonium sulfate (3102.21), or mixtures of ammonium nitrate with calcium carbonate (3102.40). This classification is strictly guided by General Interpretative Rule (GIR) 1, which prioritizes the terms of the headings and any relative Section or Chapter Notes. Chapter 31 Note 2 defines the substances that fall under heading 3102. For a product to be classified here, it must be a mineral or chemical nitrogenous fertilizer, whether or not pure, or a mixture of such products. The \"other\" designation in 3102.90 is crucial for innovative fertilizer blends or less common nitrogenous compounds that are not explicitly listed elsewhere. It is important to note that if the fertilizer contains other primary nutrients like phosphorus or potassium in significant quantities, it may be moved to heading 3105. The classification also considers the physical form, such as tablets or similar forms, or in packages of a gross weight not exceeding 10 kg, which might shift the classification to 3105.10.

Products Included

• Calcium cyanamide containing not more than 25% by weight of nitrogen
• Mixtures of ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances
• Double salts and mixtures of calcium nitrate and magnesium nitrate
• Other nitrogenous mineral or chemical fertilizers not specified in 3102.10 through 3102.80

Common Misclassification

A frequent error is classifying these products under 3102.10 (Urea) if the product contains urea but is actually a mixture. Another common mistake is using 3105.20 (NPK fertilizers) when the product only contains nitrogen but is mistakenly thought to be a complex fertilizer. Additionally, if the nitrogenous fertilizer is packaged for retail sale in small quantities (under 10kg), it must be classified under 3105.10 regardless of its chemical composition.

FAQ

What is the HS code for nitrogen fertilizer?

The HS code is 3102.90 for nitrogenous fertilizers that are not urea, ammonium sulfate, or other specifically named compounds.

Can 3102.90 include liquid fertilizers?

Yes, provided they are nitrogenous mineral or chemical fertilizers and do not fall under the specific liquid category of 3102.80, which is reserved for mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution.
