Fertilizers, mineral or chemical; potassic, potassium sulphate

HS code 310430 covers the classification of potassium sulphate, a vital mineral fertilizer used extensively in agriculture. As a key source of potassium, this fertilizer plays a crucial role in supporting plant growth and development, making it an essential input for the global food production industry. The potassium sulphate market is closely tied to the broader agricultural sector, with demand fluctuating based on factors such as crop yields, soil conditions, and farming practices around the world.

Potassium sulphate is primarily produced through chemical processing methods. The main production technique involves reacting potassium chloride with sulphuric acid to create the potassium sulphate compound. This process may also involve additional steps such as crystallization, drying, and granulation to obtain the desired product specifications. Manufacturers utilize specialized equipment and carefully controlled reaction conditions to ensure consistent quality and purity levels.

The key inputs required for the production of potassium sulphate include potassium chloride, sulphuric acid, and various processing aids such as water and energy sources. Potassium chloride serves as the primary raw material, while sulphuric acid is used to facilitate the chemical reaction. Manufacturers also rely on specialized machinery, including reactors, crystallizers, and drying equipment, to transform the raw materials into the final potassium sulphate product.

The primary output of HS code 310430 is potassium sulphate, a mineral fertilizer that is widely used in agriculture to supplement potassium levels in soils. This fertilizer is often blended with other nutrients, such as nitrogen and phosphorus, to create comprehensive fertilizer formulations. The potassium sulphate produced under this code may be consumed by various 310510 Fertilizers, mineral or chemical; nitrogenous, 310520 Fertilizers, mineral or chemical; phosphatic, and 310560 Fertilizers, mineral or chemical; containing the two or three fertilizing elements: nitrogen, phosphorus and potassium codes, as well as by the broader agricultural industry.
