Germany, the United States, and China are the leading exporters of potassium iodide, collectively accounting for over 60% of global export value in recent years; major importers include India, South Korea, and Brazil, driven by pharmaceutical and radiological preparedness demand. Import volumes into India and South Korea have risen steadily since 2022, coinciding with increased regulatory stockpiling and generic drug manufacturing activity, while potassium iodide prices have remained relatively stable amid consistent supply from top exporting nations.
Potassium iodide is a white, crystalline, odorless solid that is highly soluble in water and non-volatile, with a melting point of 681 °C and decomposition above 1330 °C. It is an inorganic ionic salt composed of potassium cations and iodide anions. Industrially, it serves primarily as a source of iodide ions in the synthesis of organic iodides, radiopharmaceuticals, and iodinated contrast media. Its key application areas include pharmaceuticals (e.g., thyroid protection agents and expectorants), nutritional supplements (iodine fortification), and specialty chemicals for analytical reagents and photographic emulsions.
Manufacture photographic emulsions, in animal & poultry feeds to the extent of 10-30 ppm, in table salts & in some drinking water.
