Aurubis Beerse NV has successfully achieved third-party verification under Tin Code Assurance, reenforcing its commitment to responsible sourcing and transparent supply chain practices.

The independent assurance, conducted by ARCHE Advisors, covered Aurubis Beerse’s Belgium tin smelter and included review of its due diligence systems and public reporting against the ITA-RMI Assessment Criteria for Tin Smelting Companies (version 2, 25th March 2021), with the assurance report dated 11 April 2026.

Key Highlights:

• This verification relates specifically to Standard 7.3 (Responsible Sourcing), one of the 72 environmental, social and governance standards of the Tin Code.
• Aurubis Beerse has implemented policies and procedures to assess potential risks and seek to avoid support to conflict, human rights abuses, and other significant harms.
• During the reporting period, the Beerse site sourced mainly recycled (secondary) materials, along with limited intermediate materials (e.g., FeSn hardhead) and unused metal products. All intermediate and additional materials were sourced exclusively from RMAP Conformant smelters.
• An independent alignment assessment confirmed that the Tin Code Assurance process and Standard 7.3 Criteria are fully aligned with the OECD Due Diligence Guidance for Responsible Sourcing of Minerals from Conflict-Affected and High Risk Areas, including standards, implementation, and audit management process under the Tin Code.

Looking Ahead: This rating for Standard 7.3 (Responsible Sourcing) was determined according to the normal Tin Code validation procedure following Aurubis Beerse’s independent assurance engagement. It will be included in the next scheduled Tin Code Report covering all 72 ESG standards.

See the following for additional context on Tin Code Assurance, its independent validation process, and how it is used by tin users and downstream stakeholders.

On 21 April 2026, a delegation from PT Timah’s new leadership team visited ITA’s UK offices in St Albans.

PT TIMAH President Director Mr Restu Widyantoro, Production and Commercial Director Mr Ilhamsyah Mahendra, and Advisor to the director Mr. Erwin Chairuman, met with by ITA CEO Helen Prins, along with members of ITA’s Markets, Technology and Sustainability teams. PT Timah’s UK-based trading subsidiary, led by Director Rolan Rizki, was also in attendance.

Building on ITA’s visit to Indonesia last year, discussions covered a broad range of topics including global challenges facing the industry, the current situation on Bangka, and latest regulatory reforms in Indonesia.

As the world’s top exporter of refined tin, Indonesia plays a crucial role in shaping the global outlook for the metal. Given the reset of RKAB timelines heading into Q2, Indonesia’s regulatory landscape is back in focus, with only 150 tonnes traded on Indonesian exchanges so far in April. RKAB approvals are underway and exports should resume in the next couple of weeks.

Following the industry shake up seen in Indonesia over the past two years, PT Timah is well positioned to boost production in 2026. The company is targeting refined production of 29,085 tonnes in 2026, a strong improvement on last year’s 17,815 tonnes.

In the wake of the government crackdown on illegal tin mining launched last year, progress has been made. However, tackling the issue of informal mining remains a key priority. During the visit, PT Timah reaffirmed its commitment to the industry’s global ESG reporting standard, the Tin Code.
