Iodine Market Outlook (2022-2032)

Newly-released data on the iodine market reveals that global sales are expected to reach around US$ 1.43 Bn in 2022, registering Y-o-Y growth of approximately 5.7%. The market for iodine is projected to exhibit a CAGR of 4% over the period of 2022 and 2032 on a volume basis.

Iodine is used as a contrast agent in radiographic modalities. Iodine's high atomic number and density make it an ideal material for this application. Its presence in the body can help improve the contrast between tissues, blood vessels, and organs with similar X-ray densities.

Iodine is also widely used as a chemical catalyst in a variety of applications, including ketone synthesis and acid esterification. Iodine catalysts are used in the production of acetic acid and synthetic rubbers. For example, the carbonylation of methanol with hydrogen iodide as a catalyst produces nearly 75% of acetic acid used in the chemical industry.

Growing adoption of iodine in the healthcare sector for medical imaging purposes and the wide usage of iodine to conduct catalytic reactions in chemical companies are propelling the growth of the iodine market across the world. These two applications of iodine account for around 40% share of the overall market.

Over the historical period (2017-2021), the global market for iodine witnessed year-over-year growth of around 4.1%. High demand from end-use sectors created a favorable macroeconomic environment for iodine manufacturers in the recent past. End markets, including chemicals, pharmaceuticals, and electronics, have witnessed substantial growth on a global level. Robust domestic demand for chemical- and pharmaceutical-based products has been a key factor responsible for the growth of the target market.

Significant growth in the pharmaceutical sector, enhancement in healthcare infrastructure, and an increase in the production of medicinal drugs and medicine are all anticipated to propel the demand for iodine over the coming years. Growing demand for raw materials and intermediates has been observed for the production of several medicines, which is benefiting iodine producers. Higher product awareness and commercialized production of iodine will also bolster market growth.

Iodine is also utilized to create polyvinyl alcohol polarizing films with iodine adsorbed for LCDs in electronic devices such as televisions, computers, digital cameras, and personal mobile devices. Polarizers are added to LCDs to increase the light contrast between the screen and the liquid crystals, increasing the LCD's visibility. Thus, increasing demand for televisions and computer screens, especially large-size screens, will provide decent growth opportunities in the market.

China, the U.S., India, Germany, and the U.K. lead the market as far as the consumption of iodine is concerned. As per this detailed study by Persistence Market Research, the worldwide iodine market is forecasted to expand at a value CAGR of 5.7% and reach a market size of US$ 2.49 Bn by the end of 2032.

Rising Incidence of Iodine Deficiency among Worldwide Population

Iodine is a key mineral for the production of the thyroid hormone in the human body. Since the human body does not produce iodine, the same can be consumed in various food items. Iodine deficiency can lead to the enlargement of goiter, mental retardation in children and infants, and other health issues.

Iodine deficiency is prominent in many adults and infants, especially in developing countries across the globe. Iodine deficiency can cause thyroid problems, including hypothyroidism, hyperthyroidism, thyroid nodules, and thyroid cancer. Iodine deficiency disorder can be prevented by consuming around 150 micrograms of iodine per day for a human adult.

Thus to overcome this deficiency, the most popular practice is to add small amounts of iodine to table salt, commonly known as iodized salt. Moreover, iodine tablets and syrups are gaining preference in developing regions, which, in turn, is fueling market growth.

Increasing Application of Iodine in Healthcare Sector

Increasing research in healthcare has spawned interest in many new elements and possible materials that can be used for treatment and diagnostics. Iodine has gained popularity as its use in the healthcare industry is being explored.

Cancer has been a matter of concern for the scientific community for quite a while, and research on the treatment for cancer has only gained impetus in recent times. Radioactive iodine can be an effective type of treatment for cancer of the thyroid gland. This is due to the fact that radioactive iodine consumed through a drink or capsule is absorbed into the body and picked up by thyroid cancer cells even if they have spread to other body parts. This radiation then goes on to destroy these cancer cells.

This new development can bring revolutionary changes in the way iodine is used in the healthcare industry.

Iodine Recycling Gaining Wide Acceptance

Iodine is widely used as a catalyst in chemical reactions, as a contrast agent, as an absorber in electronics, and as a disinfectant. Thus, to minimize the depletion of natural resources through processes such as the extraction of nitrite ores from the Earth’s crust, iodine recycling is gaining preference in Chile and Japan.

Iodine recycling is expected to increase in the near future mainly due to growing concerns about sustainability in the iodine production process. Moreover, most of the iodine recycling volume is expected from electrical and electronic equipment waste, especially from LED/LCD polarizing films.

  • According to the World Iodine Association, it was estimated that nearly 6,000 metric tons of iodine are recycled every year, accounting for approximately 18% of the global iodine demand.

Thus, the shifting preference toward sustainability and increasing focus on iodine recycling, especially in emerging economies, are expected to provide ample growth opportunities to well-established as well as new players manufacturing iodine.
