Fertilizers, mineral or chemical; potassic, potassium chloride

HS code 310420 covers the classification of potassium chloride, a vital mineral fertilizer used globally to enhance agricultural productivity. As a key component of many fertilizer blends, potassium chloride plays a crucial role in supporting the growth and development of a wide range of crops, making it an essential input for the agricultural industry worldwide.

Potassium chloride is primarily produced through the mining and processing of natural mineral deposits. The raw material is extracted from underground salt mines or solution mining operations, where it is dissolved in water and then crystallized through evaporation. The resulting potassium chloride crystals are then dried, refined, and sometimes granulated to meet the specific requirements of the fertilizer industry.

The main inputs required for the production of potassium chloride include the raw mineral deposits, energy sources for mining and processing, and water for the dissolution and crystallization processes. Specialized mining and processing equipment, such as excavators, crushers, and evaporation tanks, are also essential for the efficient extraction and refinement of the final product.

Potassium chloride produced under HS code 310420 is a widely used fertilizer, primarily consumed by the agricultural sector 310510 Fertilizers, mineral or chemical; nitrogenous and 310520 Fertilizers, mineral or chemical; phosphatic. It is often blended with other nutrients, such as nitrogen and phosphorus, to create comprehensive fertilizer formulations that cater to the specific needs of different crops and soil conditions.
