HS Code for Phosphorus potassium fertilizer

Fertilizers containing both phosphorus and potassium are classified under HS code 3105.60. This classification is governed by Chapter 31, which deals with fertilizers. Heading 3105 is reserved for mineral or chemical fertilizers containing two or three of the fertilizing elements: nitrogen, phosphorus, and potassium. Specifically, subheading 3105.60 is used for fertilizers that contain only phosphorus and potassium, commonly known as PK fertilizers. These products are typically mixtures of chemical compounds or complex fertilizers produced by chemical reaction. The classification is determined by the presence of these two specific macronutrients and the strict absence of nitrogen. If nitrogen were present, even in small amounts, the product would be reclassified under 3105.20. This code is crucial for the agricultural trade, allowing for the precise tracking of nutrient blends used in soil management and ensuring compliance with agricultural standards regarding nutrient density and composition.

Products Included

• PK (Phosphorus-Potassium) binary fertilizers
• Liquid phosphorus-potassium blends
• Granulated PK fertilizer mixtures
• Potassium phosphate compounds used as fertilizer
• Blends of superphosphates and potassium chloride

Common Misclassification

This code is frequently confused with 3105.20, which is for NPK fertilizers containing nitrogen. It is also often misclassified under 3103 (purely phosphatic) or 3104 (purely potassic) if the user fails to recognize the multi-nutrient nature of the blend. Another error is using 2835 for pure chemical phosphates not intended for fertilizer use.

FAQ

What is the HS code for PK fertilizer?

The HS code for fertilizers containing the two elements phosphorus and potassium is 3105.60.

What if the fertilizer contains a small amount of nitrogen?

If nitrogen is present, the fertilizer must be classified under 3105.20 (NPK) rather than 3105.60.
