24 June 2025

Nemak S.A.B de C.V has achieved ASI Performance Standard V3 (2022) Certification for the manufacture of motor blocks and electric housings as well as the development centre at their Nemak Dillingen plant (Nemak Dillingen GmbH, Nemak Dillingen Casting GmbH & Co. KG) located in Dillingen, Saarland, Germany.

Aluminium Stewardship Initiative (ASI) today announced that Nemak Dillingen GmbH and Nemak Dillingen Casting GmbH & Co. KG have been certified against the ASI Performance Standard V3 (2022). The certified operations produce aluminium components for the automotive industry, including engine blocks and e-engine housings. Production processes at the site include core package systems with gravity casting, heat treatment, and further processing.

The ASI Certification program was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The ASI Performance Standard V3 (2022) was launched in May 2022 following a multi-year revision process. It defines 11 principles and 62 criteria under three sustainability pillars – Environment, Social, and Governance – with the aim to address pressing sustainability issues in the aluminium value chain, such as biodiversity, Indigenous Peoples’ rights, circularity, and greenhouse gas emissions.

The independent, third-party audit of Nemak Dillingen GmbH and Nemak Dillingen Casting GmbH & Co. KG was carried out by TÜV Rheinland Cert GmbH. A full listing of audit findings outlining evidence of conformances and minor non-conformances is available from page 5 of the summary audit report, linked below. Five minor non-conformances are noted under Criteria 2.3b Environmental and Social Management Systems – Social, 3.4a-f Stakeholder Complaints, Grievances and Requests for Information, 9.1a-d Human Rights Due Diligence, 9.2a-e Gender Equity and Women’s Empowerment and 10.6a-g Violence and Harassment. During the Certification Period, Nemak Dillingen GmbH and Nemak Dillingen Casting GmbH & Co. KG will be implementing a corrective action plan, which will be verified in follow-up audits.
