ASI certifies Nemak Dillingen GmbH, Nemak Pilsting GmbH, Nemak Linz GmbH and Nemak Wernigerode GmbH against Chain of Custody Standard V2

25 November 2025

Nemak S.A.B de C.V has achieved ASI Chain of Custody (CoC) Standard V2 (2022) Certification for its multi-site operations covering the Nemak Dillingen, Pilsting and Wernigerode facilities in Germany, and the Nemak Linz facility in Austria.

Aluminium Stewardship Initiative (ASI) today announced that Nemak Dillingen GmbH, Nemak Pilsting GmbH, Nemak Linz GmbH and Nemak Wernigerode GmbH hve been certified against the ASI Chain of Custody Standard V2 (2022). Together, the facilities produce aluminium components for the automotive industry, including engine blocks, e-engine housings, cylinder heads, and structural components, supported by advanced technologies such as ROTACAST and an integrated Product Development Centre.

The ASI CoC Standard V2 sets out requirements for the creation of a Chain of Custody for material that is produced and processed through the value chain into diverse downstream sectors. The implementation of ASI’s CoC Standard links verified practices at successive steps of the supply chain – certified under the ASI Performance Standard – to the materials produced by ASI Certified Entities. The CoC Standard also confirms that appropriate policies and due diligence processes are in place to identify and address critical issues, such as corruption, human rights abuses, materials originating from conflict-affected and high-risk areas in the supply chain and support responsible sourcing.

The independent, third-party audit of the Nemak facilities was carried out by TÜV Rheinland Cert GmbH. A full listing of audit findings outlining evidence of conformances is available from page 5 of the summary audit report, linked below. No non-conformances were identified during the Chain of Custody Certification audit.
