HS Code for Nitrogen phosphorus fertilizer

Nitrogen phosphorus fertilizers that do not fall under the specific categories of nitrates or phosphates are classified under HS code 3105.59. This classification is based on Chapter 31, Note 4, which dictates that fertilizers containing two or three of the fertilizing elements (nitrogen, phosphorus, and potassium) are to be classified in heading 3105. Since this product contains both nitrogen and phosphorus but lacks potassium, it is categorized as a binary fertilizer. Subheading 3105.59 serves as a residual category for "other" mineral or chemical fertilizers containing these two elements that are not specifically mentioned in other subheadings like 3105.30 (diammonium phosphate) or 3105.40 (monoammonium phosphate). The classification process involves verifying that the product is a mineral or chemical fertilizer and that the nitrogen and phosphorus are either chemically bonded or physically mixed in a way that provides both nutrients to plants. This code is essential for tracking the trade of specialized agricultural inputs that provide a balanced nutrient profile for specific soil requirements.

Products Included

• Binary nitrogen-phosphorus (NP) mineral fertilizers
• Chemically combined nitrogen and phosphorus compounds (excluding pure phosphates)
• Blended NP fertilizers in granular or powder form
• Other mineral fertilizers containing N and P not elsewhere specified

Common Misclassification

The most common misclassification occurs with HS codes 3105.30 and 3105.40. These codes are specifically for diammonium phosphate (DAP) and monoammonium phosphate (MAP), respectively. If the product is a pure or commercially pure ammonium phosphate, it must be classified there rather than in the general 3105.59 category. Additionally, if the fertilizer contains even a trace amount of potassium intended as a nutrient, it must be classified under 3105.20 as an NPK fertilizer. Confusion also arises with 3103.11, which is for superphosphates, but that code is only for fertilizers containing only phosphorus as a primary nutrient.

FAQ

What is the HS code for nitrogen phosphorus fertilizer?

The HS code for nitrogen phosphorus fertilizers, other than specific nitrates and phosphates, is 3105.59.

Can organic fertilizers be classified under this code?

No, HS code 3105.59 is strictly for mineral or chemical fertilizers. Animal or vegetable fertilizers, whether or not mixed together or chemically treated, are classified under heading 3101.
