Iodine Production by Country

Iodine production by country measures how much iodine each country produces, expressed in tonnes. The figures refer to production of iodine, in line with the underlying sources. The statistics combine an Our World in Data series (2020-2024, with no 2021 values, built from the USGS Mineral Commodity Summaries and the BGS World Mineral Statistics) with 2024 and 2025 estimates taken directly from the USGS Mineral Commodity Summaries 2026. The table below lists 9 countries that record iodine production in the period. 2025 figures are available individually for 7 countries, which produced a combined 33,768 tonnes in 2025, slightly below the reported World total of 34,000 tonnes in the source. The United States is listed in the source as withheld (W), and China keeps its last available value from 2023 (600 tonnes).

Countries With the Largest Iodine Production in 2025

Chile produced the most iodine in 2025 with 23,000 tonnes. Japan ranked second with 9,000, followed by Turkmenistan (800), Iran (700), Azerbaijan (210), Indonesia (50), and Russia (8).

Chile alone accounted for about 68 percent of the World total in 2025, and Chile and Japan together for about 94 percent; the top three countries accounted for about 96 percent. Chile's production was about 2.6 times that of Japan. Only two countries produced more than 5,000 tonnes in 2025.

Iodine Production Around the World

In South America, Chile (23,000) is the dominant producer. In Asia, Japan (9,000) leads, ahead of Turkmenistan (800) and Indonesia (50); Azerbaijan (210) is on the Caspian side of the region, and Iran (700) is in the Middle East. In Europe and northern Asia, Russia (8) is the only listed producer. The United States has earlier production values in the dataset, but its 2024 and 2025 values are withheld (W) in the source.

Largest Changes in Iodine Production, 2024-2025

Chile recorded the largest increase, rising from 22,400 tonnes in 2024 to 23,000 in 2025 (up 600, about 2.7 percent). Indonesia rose from 30 to 50 tonnes (up 20, about 67 percent), and Russia from 5 to 8 (up 3, about 60 percent).

Japan recorded the largest decline, falling from 9,300 to 9,000 tonnes (down 300, about 3.2 percent). Turkmenistan (800), Iran (700), and Azerbaijan (210) held their levels. The World total rose from 33,400 to 34,000 tonnes (up 600, about 1.8 percent).

The 2024 figures in this release are revised from earlier values, most notably Chile (revised up from 22,000 to 22,400 tonnes), Turkmenistan (up from 770 to 800), and Russia (up from 3 to 5).

Methodology

The 2020-2023 figures come from Our World in Data, which compiles national iodine production figures from the USGS Mineral Commodity Summaries, the USGS Historical Statistics for Mineral and Material Commodities, and the BGS World Mineral Statistics, with major processing by Our World in Data; USGS data is prioritized, with BGS data used to supplement it. The earlier series covers 2020, 2022, and 2023, with no 2021 values. The 2024 and 2025 figures are estimates from the USGS Mineral Commodity Summaries 2026 where available; China keeps its last available Our World in Data value (600 tonnes from 2023). Values refer to iodine production, in tonnes, and 2025 figures are preliminary estimates from the source. The source lists the United States as withheld (W) to avoid disclosing company proprietary data, which is why the 2024 and 2025 U.S. cells remain empty. The sum of individually reported country estimates does not equal the reported World total because the source applies rounding and other adjustments at the country and World levels. In the table, a zero reflects no production, while an empty cell means that no value was reported.
