Potassium Iodide Global Market Report 2026

Potassium iodide (KI) is a compound composed of potassium and iodine, widely utilized as a nutritional supplement and in medical treatments for thyroid-related issues. It serves as a radiation protective agent, shielding the thyroid gland from absorbing radioactive iodine during nuclear emergencies.

The primary product types of potassium iodide include solid and liquid forms. Solid potassium iodide refers to the crystalline structure of KI, commonly employed in medicine, photography, and analytical chemistry. Various grades are available, including industrial, pharmaceutical, and feed grades, used across applications such as the pharmaceutical sector, nutritional supplements, industrial uses, radiation protection, photography, and other imaging applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have influenced the potassium iodide market by increasing costs for imported iodine raw materials, purification chemicals, and pharmaceutical processing equipment. These impacts have been particularly visible in pharmaceutical and radiation protection applications across North America, Europe, and parts of Asia-Pacific that rely on cross-border iodine sourcing. Elevated tariffs have contributed to pricing volatility and supply planning challenges for emergency stockpiles. In response, manufacturers are strengthening domestic iodine refinement, improving supply chain resilience, and investing in local pharmaceutical-grade production. In some regions, tariffs have supported the development of localized strategic reserves and domestic chemical manufacturing capacity.

Rising health consciousness is driven by increasing awareness of the importance of preventive healthcare, improved access to health-related information, and a desire for better quality of life. Potassium iodide is used by health-conscious individuals to support healthy thyroid function and prevent iodine deficiency disorders, aligning with their proactive approach to overall wellness. For instance, in November 2025, according to Gov.ie, an Ireland-based official government website, 82% of respondents aged 15+ rated their general health as "good" or "very good." Therefore, rising health consciousness is driving the growth of the potassium iodide market.

Major companies operating in the potassium-iodide market are adopting a strategic partnership approach to enhance product accessibility and cater to diverse consumer needs. Strategic partnerships refer to a process in which companies leverage each other's strengths and resources to achieve mutual benefits and success. For instance, in April 2023, the Delaware Emergency Management Agency (DEMA), a US-based state emergency preparedness agency, in collaboration with the Delaware Division of Public Health (DPH), a US-based Department of Health and Social Services, distributed potassium iodide (KI) tablets to residents living within a ten-mile radius, known as the Emergency Planning Zone (EPZ), of the Salem or Hope Creek Nuclear Generating Stations. These tablets are available to safeguard the thyroid gland from ingested or inhaled radioactive iodine that may be released during a radiation emergency. These tablets are part of Delaware's emergency plans for use in a nuclear incident and are provided through a program initiated by the U.S. Nuclear Regulatory Commission (NRC).

In October 2023, Iofina plc, a UK-headquartered provider of iodine extraction and specialty halogen-based chemicals, signed an agreement with a new brine water supply partner to construct its IOsorb(R) plant "IO#10" in Western Oklahoma under ongoing supply terms. With this agreement, Iofina aimed to secure a long-term feedstock supply of iodine-rich brine, enabling expansion of its iodine and related iodide derivative output, stabilizing raw material access, and supporting consistent product availability. The brine supply partner is a US-based oil and gas operator providing iodide-rich brine water to Iofina's extraction facility for iodine and iodide recovery.
