How the tin-content figure is worked out. PT Timah reports tin ore production of 18,635 tons of Sn in 2025, a measure expressed as tin content. The figure is for the whole company across its mining areas, not for a single mine. World mine production of tin in 2025 was 290,000 tonnes (USGS Mineral Commodity Summaries 2026); Indonesia produced 61,000 tonnes.
Status: operating, as of 31 December 2025.
- This is a company-level figure covering all of PT Timah's onshore operations on Bangka and Belitung and its offshore operations in the waters around Bangka and in the Kundur Islands (Riau Islands Province). The annual report prints no split by mine or by area (printed p.255).
- The report says a significant portion of mining operations involves partners (printed p.73) and that onshore and offshore mining is affected by illegal mining within the company's IUP areas (printed p.72).
- The report says several mining business licenses (IUP) were in renewal, including five suspended IUPs, which meant mining activities could not be scheduled at those locations (printed p.259).
- The company also prints tin metal production of 17,815 metric tons (a refined and smelted product) and tin metal sales of 16,634 metric tons for 2025. These are not mine output and are not used.
- USGS prints 61,000 t of tin for Indonesia in 2025 (estimated).

Method and limits
- Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
- Shares. A share divides output in tin content by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
- Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
- Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every tin mine. Shares of a country's output mix periods and bases, so treat them as indicative.
