Phosphates; of potassium, whether or not chemically defined

HS v2017 Code: 283524

About phosphates; of potassium, whether or not chemically defined

HS code 283524 covers potassium phosphates, which are essential inorganic compounds used in a variety of industrial and agricultural applications. As a key source of phosphorus and potassium, these compounds play a crucial role in the production of fertilizers, detergents, and other chemical products that support global food production and industrial processes. The demand for potassium phosphates is closely tied to the growth of the agricultural and manufacturing sectors, making this industry an important contributor to the broader economy.

Production process

Potassium phosphates are typically produced through the reaction of phosphoric acid and potassium hydroxide or potassium carbonate. The resulting solution is then evaporated and crystallized to obtain the desired potassium phosphate compound, which may be further processed or refined depending on the specific application. Advanced production techniques often involve the use of continuous crystallization and centrifugation to improve yield and product quality.

Production inputs

The main inputs required for the production of potassium phosphates include phosphoric acid, potassium hydroxide or potassium carbonate, and various energy sources such as electricity or steam. Specialized equipment, such as reactors, evaporators, and crystallizers, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and quality control.

Production outputs

The primary outputs of HS code 283524 are various forms of potassium phosphates, including monobasic, dibasic, and tribasic potassium phosphates. These compounds find widespread use in the production of 310000 Fertilizersand 340000 Soap, organic surface-active agents, washing preparations, lubricating preparations, artificial waxes, prepared waxes, polishing or scouring preparations, candles and similar articles, modelling pastes, 'dental waxes' and dental preparations with a basis of plasteras well as in the formulation of 283000 Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes.
