New Tin Code Reports Published (Aug–Oct 2025): Taboca and PT Timah Tbk 

We’re pleased to share two new Tin Code reports from leading tin producers from Brazil and Indonesia highlighting continued engagement with the Code and clear steps towards progressive improvement. 

August — Mineração Taboca S/A (Brazil) 

Taboca’s third Tin Code report confirms multiple areas now third-party verified via ISO certifications and PwC’s assurance of the 2022 Corporate Sustainability Report. Highlights include verification of policies and management systems (Principle 1), environmental management (2.1), H&S systems and training (3.1–3.5), and waste management (2.9–2.10). The company is progressing on tailings management as it works towards conformance with the Global Industry Standard on Tailings Management, alongside ongoing work on biodiversity, energy and closure planning.  

September — PT Timah Tbk (Indonesia) 

PT Timah Tbk’s third Tin Code report records third-party verification for greenhouse gas accounting, energy management and onshore biodiversity. The report also transparently reflects the context and impact of Indonesia’s national corruption investigation (~2015–2022). PT Timah Tbk cooperated with authorities and states its commitment to continued annual Tin Code reporting and other international sustainability disclosures.
