Product classification
HS code for Phosphorus potassium fertilizer: 3105.60
Fertilizers, mineral or chemical, containing the two fertilizing elements phosphorus and potassium.
Classification of phosphorus potassium fertilizer under HS 3105.60
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.

Codes often confused with 3105.60
Common mistake. 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.
Top exporters and importers of HS 310560 (the code used for phosphorus potassium fertilizer), 2025

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
