Indonesia Tin Working Group



Indonesia’s Bangka-Belitung region supplies approximately 30 percent of the global tin market and 90 percent of the country’s exported tin. Tin production in Indonesia is associated with significant risk areas including social/economic risks, occupational health and safety, environmental degradation, and challenging legal/regulatory issues.

The Tin Working Group (TWG) is the first voluntary, collaborative, multi-stakeholder initiative that aims to make meaningful change in the Indonesian tin sector. Launched in 2014, the TWG works with downstream companies, midstream processors, local tin producers, civil society, industry associations, and the central and regional Indonesian government. Through the TWG, companies are contributing to the development of responsible tin mining in Indonesia via direct engagement with government and local stakeholders, providing support to their supply chain partners, and setting supply chain expectations for responsibly produced tin.

Phase I (2014-2017) was led by the Sustainable Trade Initiative IDH as the international convener. This current Phase II (2017-2019) of the TWG will be led by the RBA's Responsible Minerals Initiative.


Responsible tin mining practices in line with international best practices are adopted and implemented by the majority of tin producers in Indonesia, resulting in better social and economic conditions for Indonesia tin mining communities.


The high-level mission of the TWG is to identify and mitigate, through effective engagement with and support of international and local stakeholders, the sustainability challenges of tin mining and smelting in Indonesia, while recognizing the economic benefits of the sector.

Specifically for Phase II of the TWG, the group will utilize a multi-stakeholder and inclusive approach, working closely with key local industry players and local communities, to identify and act on opportunities to advance land reclamation projects, policy reform, and worker health and safety improvements.

The TWG Overview and roadmap provide more details on the TWG’s objectives and activities to achieve our mission.

Locally, the TWG is supported by our Local Advisory Committee who works to build local buy in and ensure ownership of TWG Phase II activities as well as advise local government bodies with a view to establish enabling conditions for local companies to implement responsible tin mining practices. The Local Advisory Committee includes representatives of government, private sector, civil society as well as subject matter experts.

What We Do

The TWG will build on the efforts and achievements of Phase I and continue the engagement with local as well as international stakeholders. The TWG, through funding received from the European Partnership on Responsible Minerals (EPRM), will support pilot project activities for land reclamation as well as occupational health and safety (OHS) capacity building. Throughout this process, the TWG will seek to demonstrate the business case for responsible tin mining practices so as to enable Indonesian tin producers to obtain support from local and national government, industry partners, donors and socially responsible investors to implement and scale on-the-ground projects.
