ASI certifies Wuxi Dicastal Wheel Manufacturing Co., Ltd against Performance Standard V3.1 and Chain of Custody V2
Its operations include casting, heat treatment, machining, coating and packaging.
3 December 2025
Aluminium Stewardship Initiative (ASI) today announced that Wuxi Dicastal Wheel Manufacturing Co., Ltd has been certified against the ASI Performance Standard V3.1 and Chain of Custody Standard V2. The facility has an annual output of 9.5 million units and produces aluminium alloy wheels and cast steering knuckles for new energy vehicles. Its operations include casting, heat treatment, machining, coating and packaging, supported by ancillary facilities such as joint workshops, warehouses, and a sewage treatment station. The company has also established a digital manufacturing system with integrated production, material, quality, equipment, and data management functions.
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 and ASI CoC Standard V2 were launched in May 2022 following a multi-year revision process. The 2022 Standards and related documents underwent a minor update in 2023, accounting for editorial changes, correction of minor errors and for general clarification, culminating in the release of Performance Standard V3.1 (2023) and Chain of Custody Standard V2.1 (2023).
The ASI Performance Standard 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 ASI CoC Standard 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 products produced by ASI Certified Entities. The CoC Standard also confirms that appropriate policies and due diligence process 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.
