Product classification
HS code for Nitrogen phosphorus fertilizer: 3105.59
Fertilizers, mineral or chemical, containing the two fertilizing elements nitrogen and phosphorus, other than nitrates and phosphates.
Classification of nitrogen phosphorus fertilizer under HS 3105.59
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.

Codes often confused with 3105.59
Common mistake. 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.
Top exporters and importers of HS 310559 (the code used for nitrogen phosphorus fertilizer), 2025
In 2025, the largest exporter of HS 310559 (the code used for nitrogen phosphorus fertilizer) in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was Brazil, with 34% of world imports.

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).
