The International Tin Association (ITA) Lead Sustainability Specialist Sonia Marsh and Sustainability Associate Liam Rafferty-John travelled to Brazil in February to visit ITA member and leading tin producer White Solder Metalurgia e Mineracão LTDA (White Solder) and gain a deeper understanding of the local tin mining context.
As the world’s sixth largest producer of refined tin, Brazil is of key importance to the global tin industry. The visit provided insights into key social and environmental considerations and how the national tax system and disclosures contribute to transparency in the mineral sector.
The visit included a tour of White Solder’s smelter and solder manufacturing facilities and local mining operations. A key focus was the practical application of the Tin Code for ESG disclosures and its role in promoting continuous improvement in sustainability, including engagement with small-scale suppliers.
A highlight was the visit to the recently inaugurated Community Centre TST, a state-of-the-art facility fully funded by White Solder, providing vital daycare, educational, and skills development support to local families. This initiative strongly aligns with the community engagement and development principles encouraged by the Tin Code.
ITA extends its sincere thanks to the entire team at White Solder and the Tor Participações Holding Group for hosting the visit. Such engagement is crucial as ITA continues to support its members and promote continuous improvement in responsible tin production worldwide.
