The certified scope covers a melting centre and facilities for the casting and machining of aluminium parts for the automotive industry, and includes two outsourcing contractors. The facility achieved Performance Standard V3.1 (2023) Certification in December 2025.Aluminium Stewardship Initiative (ASI) today announced that Nemak Spain SL has been certified against the ASI Chain of Custody Standard V2 (2022). The Certification covers the manufacture of high-pressure diecast aluminium components for the automotive industry, including parts such as transmissions, engine blocks, and oil pans, with an annual production capacity of approximately 2.5 million units. The production site includes a melting centre, casting operations, and machining facilities.
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 Nemak Spain SL 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. One non-conformance was identified during the Chain of Custody Certification audit under Criterion 7.2 Risk Assessment and Mitigation.
