About HS Code 310559
This HS code covers mineral or chemical fertilizers containing the two fertilizing elements nitrogen and phosphorus, but specifically excludes those where nitrogen is exclusively in nitrate form and phosphorus is exclusively in phosphate form (covered by 310551). This 'other' category encompasses a broad range of N+P compounds, such as urea ammonium phosphate, ammonium polyphosphate, and various N-P blends where nitrogen might be in urea or ammonium form. These fertilizers are vital for balanced plant nutrition, supporting vegetative growth and root development. Global trade is extensive, with major agricultural economies both importing and exporting these diverse formulations. Key players include countries with robust fertilizer industries like China, the United States, and Russia, supplying markets in Brazil, India, and Southeast Asia. The specific chemical forms of N and P dictate their release rates and suitability for different soil conditions and crops.
Products Under This Code
Urea ammonium phosphate, ammonium polyphosphate, NPK fertilizers (without potassium) where N is not nitrate, liquid N-P fertilizers, starter fertilizers, sulfur-coated urea phosphate
Real World Examples
UAN + APP blends, MicroEssentials S10, Nutrien ESN + MAP blends, AgroLiquid Pro-Germinator, PhosAgro NPK (without K)
Common Misclassification
This 'other' category can be confused with specific N+P fertilizers like DAP (310530) or MAP (310540) if the exact chemical form isn't specified, or with NPK fertilizers (310520) if potassium is also present.
