Responsible Sourcing Assurance
We publish independent Assurance Reports and Company Reports (‘OECD Step 5 Due Diligence Reports’) for smelters who have undertaken assurance under Tin Code Standard 7.3 (Responsible Sourcing) against the ‘ITA-RMI Assessment Criteria for Tin Smelters (v2 Mar 2021)’ using the Tin Code Assurance System.
This includes the independently validated Tin Code Rating for Standard 7.3 (Responsible Sourcing).
Independent Assurance of Standard 7.3 (Responsible Sourcing)
Standard 7.3 (Responsible Sourcing) is one of 71 Environmental, Social and Governance standards of the Tin Code. As the full Tin Code Report covers a broader scope, some companies may have a standalone rating for Standard 7.3 (Responsible Sourcing) while other standards are being assessed. Full Tin Code Reports are published here.
This table contains the most recent Tin Code Assurance information. For previous years’ reports, please contact: tc@tincode.org

Notes
-
The Tin Code is not a certification. Like many other systems, it does not guarantee that minerals are conflict-free.
-
Tin Code Assurance is conducted by independent auditors registered by ITA.
