According to Persistence Market Research, the global iodine market recorded a year-on-year growth of 103.1% in 2022 and is estimated to be valued at US$ 3.6 billion in 2024. The market is projected to reach US$ 6.9 billion by the end of 2033, expanding at a noteworthy CAGR of 7.5% over the next ten years. Iodine, a nonmetallic element and the heaviest halogen in the periodic table, is found in small amounts in many natural sources, including brines and seaweeds. It is also used in analytical chemistry and photography. The radioactive isotope I-131, with a half-life of eight days, is used in medicine and other applications due to its long-lasting effect. Iodine is a dark crystalline solid that can change to deep violet when heated and produce a pungent vapor.

Maintaining optimal mental and physical development is a critical benefit of consuming iodine. Iodine deficiency can lead to a range of disabilities and disorders, including goiter, hypothyroidism, cretinism, abortion, stillbirth, mental retardation, and psychomotor defects. These consequences are often invisible and irreversible but entirely preventable with adequate iodine intake. Iodine deficiency is the leading cause of preventable brain damage globally. In areas where the soil lacks iodine, children have been found to have an average of 13.5 IQ points less than those in iodine-sufficient areas. Ensuring adequate iodine intake is crucial for individuals of all ages.

Chile and Japan are leading producers of iodine, together accounting for more than 90% of global production. The top five manufacturing companies in the world account for 60% to 65% market share in 2024. The market is estimated to create an absolute incremental $ opportunity of US$ 3.5 billion from 2024 to 2033. Sales of iodine are being driven by increasing demand for alcohols, ketones, and other organic acids due to their widespread use in the production of various chemicals and products. Overall, iodine is a crucial element with numerous applications in various industries, including medicine, chemical production, and photography. It is also essential for human health, and its deficiency can lead to significant health problems.

Persistent Market Research reveals that from 2018 to 2022, the iodine market advanced at a CAGR of 32.1%. The growth of the market is attributed to a rapid increase in product prices from 2020 to 2022 and high demand for the product in the global market. Limited supplies from leading countries led to a surge in demand and prices. Price volatility is a significant threat to iodine manufacturers. From 2024 to 2033, the market is anticipated to progress at a CAGR of 7.5%. New applications of iodine have been discovered, and researchers are continuously focusing on finding innovative applications of iodine. The widespread use of iodine in X-ray contrast media and catalysts has been driving high demand for the element in the global market.
