Nitrates; of potassium

HS code 283421 covers the classification of potassium nitrates, a vital inorganic compound with a wide range of industrial and agricultural applications. As a key component in the production of fertilizers, explosives, and various chemical processes, potassium nitrates play a crucial role in supporting global food production, infrastructure development, and industrial growth. This code sits within the broader category of inorganic chemicals, a sector that is integral to the functioning of many industries across the global economy.

Potassium nitrates are typically produced through the neutralization of nitric acid with potassium hydroxide or potassium carbonate. The resulting solution is then evaporated and crystallized to obtain the final potassium nitrate product. This process can be further refined to achieve higher purity levels, depending on the intended end-use application.

The main inputs required for the production of potassium nitrates include nitric acid, potassium hydroxide or potassium carbonate, and energy sources for the evaporation and crystallization processes. Specialized equipment such as reactors, evaporators, and crystallizers are also essential for the efficient manufacture of this inorganic compound.

Potassium nitrates produced under HS code 283421 are primarily used as a fertilizer, an oxidizing agent in explosives, and a component in various chemical processes. The outputs of this industry are often consumed by other industries, such as 310000 Fertilizers and 360100 Propellent powders, explosives, which rely on potassium nitrates as a key raw material.
