In November, ITA’s Tin Code Programme Manager Susannah Costley-White, together with independent assessors from Green Horizons Ltd, visited leading tin producers MSC (Malaysia Smelting Corporation) and state-owned company PT Timah Tbk in Indonesia, as well as separately to PT Mitra Stania Prima’s (PT MSP) smelter.

The visits provided an opportunity to engage closely with members and local stakeholders, observe operations first-hand, and support MSC and PT Timah with their upcoming Tin Code reports. This included guidance on evidence submission and alignment with Tin Code standards, helping to ensure best practice in sustainable tin production. The team explored how ITA members apply the Tin Code principles, including environmental management, health & safety, labour practices, legal compliance, human rights, and community and stakeholder engagement.

In Malaysia, ITA toured MSC’s smelting facilities, discussing ESG initiatives and practical Tin Code implementation. In Indonesia, the team visited PT Timah’s onshore and offshore mining operations and local projects in Bangka, gaining insight into how the company manages varying operations in the local context.

The visit to PT MSP’s smelter offered insight into their operations and potential collaboration on sustainability practices under the Tin Code.

ITA thanks MSC, PT Timah, and PT Mitra Stania Prima for their warm welcome and looks forward to visiting more members to support them with Tin Code reporting and sustainable tin production.

MSC is a Member of the International Tin Association and participant of the Tin Code.

Malaysia Smelting Corporation Berhad (MSC), a leading tin producer, has achieved a Third-Party Verified rating for Standard 7.3 (Responsible Sourcing) at its Pulau Indah smelter under the established Tin Code Assurance.

The independent verification conducted by third-party auditors confirms that MSC’s due diligence systems and public reporting meet the standards set by Standard 7.3 assessed against the ITA-RMI Assessment Criteria for Tin Smelting Companies (version 2, 25th March 2021) and are fully aligned with the OECD Due Diligence Guidance for Responsible Sourcing of Minerals from Conflict-Affected and High Risk Areas.

This marks the third consecutive year that MSC has undergone independent assurance under the Tin Code, reflecting its commitment to transparency, responsible sourcing, and continuous improvement in supply chain practices.

The Responsible Sourcing rating will be included in MSC’s upcoming comprehensive Tin Code Report, which covers all 72 environmental, social, and governance standards.

For further details, the rating letter, full assurance report, and due diligence documentation are available on the Tin Code website here.
