About HS Code 310540

This HS code covers ammonium dihydrogenorthophosphate, known as Monoammonium Phosphate (MAP), and mixtures of MAP with diammonium hydrogenorthophosphate (DAP). MAP is a crucial phosphatic fertilizer, offering a high concentration of phosphorus and a moderate amount of nitrogen. It is highly water-soluble, making it ideal for starter fertilizers, drip irrigation, and foliar applications, particularly in early growth stages to support root development and flowering. Global trade in MAP is substantial, driven by its versatility and effectiveness across diverse agricultural systems. Major producers include countries with significant phosphate rock reserves and ammonia production, such as China, the United States, and Morocco. Importers are widespread, with large agricultural economies like Brazil, India, and various European nations being key consumers. The trade dynamics are influenced by global crop demand and fertilizer market trends.

Products Under This Code

Monoammonium Phosphate (MAP) granular, MAP powder, water-soluble MAP, MAP-DAP blends, liquid MAP solutions, foliar MAP fertilizers

Real World Examples

Haifa MAP, Grow More MAP, ICL MAP, PhosAgro MAP, Nutrien MAP

Common Misclassification

Frequently confused with diammonium phosphate (DAP, 310530) due to their similar roles as phosphatic fertilizers; the key difference lies in their N:P ratio (MAP is typically 11-52-0, while DAP is 18-46-0).

EU Regulatory Requirements

This product falls under the Carbon Border Adjustment Mechanism (CBAM). Importers to the EU must declare embedded carbon emissions and purchase CBAM certificates.
