Tin Reserves by Country

Figures are drawn from eight editions of the USGS Mineral Commodity Summaries (2019-2026) and describe estimated reserves that can be economically extracted. Unlike mine production, reserves are not the amount mined in a given year. 12 countries appear in the table; 10 have reported 2025 values, and the listed 2025 total stands at 5,694,000 metric tons. USGS gives the world total as more than 6,000,000 metric tons, a lower bound rather than an exact figure.

Indonesia (1,400,000 metric tons) leads China (1,200,000), with the pair holding about 45.7% of the listed total between them. Myanmar and Brazil tie for third at 700,000 each, ahead of Australia (570,000) and Russia (460,000). USGS also reports 310,000 metric tons under “Other countries,” but does not assign that amount to individual countries.

Indonesia returned after two years with no reported value and recorded the largest figure in the table.

The return at the top

Indonesia reported 800,000 metric tons from 2018 through 2022, no reported value in 2023 or 2024, then 1,400,000 for 2025 — three-quarters larger than its old figure and immediately the lead. No other country in the table has a two-year reporting gap followed by a higher reported reserve value.

Brazil rebounds, China gains

Brazil held 420,000 metric tons from 2020 through 2024, then reported 700,000 for 2025 (+66.7%), tying Myanmar for third. China added 200,000 (+20.0%) to reach 1,200,000, recovering from its 2022 dip to 720,000. Together the two additions put 480,000 metric tons onto the listed total in a single year.

A leap, departures and stability

Myanmar leapt from 100,000 metric tons in 2020 to 700,000 in 2021 and has remained there since. Bolivia has likewise stayed at 400,000 throughout the series, while Thailand and Malaysia have not reported reserve values since 2018 and 2021, respectively. Among countries with 2025 values, Peru rose from 130,000 to 150,000 (+15.4%), while DR Congo fell from 120,000 to 91,000 (-24.2%) and Australia from 620,000 to 570,000 (-8.1%).

Methodology

Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are metric tons of tin content, as reported by USGS. 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.
