Boron Reserves by Country
Not a single figure in the boron table moved in 2025 — all six reported values are identical to the year before. The dataset draws on the USGS Mineral Commodity Summaries 2019-2026 and reports estimated quantities that can be economically extracted. The series tracks potentially recoverable material, not the amount mined in a given year. Listed reserves totaled 1,086,100 thousand metric tons in 2025.
Türkiye holds 950,000 thousand metric tons — about seven times the other five countries combined (136,100). The United States, second at 48,000, reports barely one-twentieth of Türkiye's figure; Russia (40,000), Chile (35,000), China (9,100) and Peru (4,000) complete the ranking. USGS marks the world total as XX (not applicable), so no numerical global total is published for this series. The smallest holder (Peru, 4,000) is less than half a percent of the leader. The gap between first and second is 902,000 thousand metric tons: Türkiye's figure could fall by nine-tenths and still lead. The United States (48,000), Russia (40,000) and Chile (35,000) sit within 13,000 of one another, forming a flat second tier whose combined total is about 13% of the leader's. All six countries reported exactly the same values as in 2024. Russia, Chile and Peru have now held identical figures in all eight years shown; the United States has been flat since its 2023 step to 48,000. Türkiye dropped from 1,200,000 to 950,000 thousand metric tons for 2023 (-20.8%) and has held that figure since. China slid from 20,000 to 9,100 for 2024 (-54.5%), less than half its 2021 level of 24,000. Both moves predate a 2025 in which the entire ranking stood still. Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are thousand metric tons, exactly as reported. Empty means the source reported no value; 0 means the source reports zero. The source’s world total, where published, may be rounded, approximate, a lower bound, or a textual estimate, so shares are computed against the sum of the listed countries. Reserves and production are different measures and should not be combined without equalizing units.

Methodology
Frequently Asked Questions
What are boron reserves?
Boron reserves are estimated quantities of boron that can be economically extracted under applicable conditions, in thousand metric tons. Production measures the amount mined in a year.
Which countries hold the most boron reserves?
Türkiye (950,000 thousand metric tons), the United States (48,000) and Russia (40,000) reported the largest 2025 values.
Did any boron reserve values change in 2025?
No. All six reported 2025 values match their 2024 figures exactly. The most recent changes were Türkiye's 2023 decline and China's 2024 decline.
Has Türkiye always led by this much?
Türkiye reported 950,000–1,200,000 thousand metric tons in all eight years, always first; second-placed United States holds 48,000.
