Fertilizers, mineral or chemical; diammonium hydrogenorthophosphate (diammonium phosphate)

HS v2022 Code: 310530

About fertilizers, mineral or chemical; diammonium hydrogenorthophosphate (diammonium phosphate)

HS code 310530 covers the classification of diammonium hydrogenorthophosphate, commonly known as diammonium phosphate (DAP). This fertilizer is a crucial input for the agricultural industry, playing a vital role in enhancing crop yields and supporting global food production. As a widely traded commodity, the production and trade of diammonium phosphate are integral to the broader economy, connecting various industries and supply chains.

Production process

Diammonium phosphate is primarily produced through a chemical reaction between ammonia and phosphoric acid. The process typically involves the neutralization of phosphoric acid with ammonia, resulting in the formation of diammonium phosphate crystals. The crystals are then dried, granulated, and sometimes coated to improve their physical properties and storage characteristics.

Production inputs

The production of diammonium phosphate requires several key inputs, including ammonia, phosphoric acid, and various other chemicals and minerals. Specialized equipment, such as reactors, granulators, and drying systems, are also essential for the manufacturing process. Additionally, the industry relies on a reliable supply of energy, water, and transportation infrastructure to support the efficient production and distribution of this vital fertilizer.

Production outputs

Diammonium phosphate is a widely used fertilizer, primarily consumed by the agricultural sector. It is often blended with other nutrients, such as nitrogen and potassium, to create complex fertilizer formulations. The output of HS code 310530 may be further processed or combined with other 310540 (Fertilizers, mineral or chemical; ammonium dihydrogenorthophosphate (monoammonium phosphate)) or 310560 Fertilizers, mineral or chemical; ammonium nitrate, whether or not in aqueous solution to create a diverse range of fertilizer products.
