ASI Chain of Custody (CoC) Standard

The ASI Chain of Custody (CoC) Standard complements the ASI Performance Standard, and is voluntary for ASI Members, though encouraged. The CoC Standard sets out requirements for the creation of a Chain of Custody for CoC Material, including ASI Aluminium, which is produced and processed through the value chain into diverse downstream sectors.

The implementation of ASI’s CoC Standard enables a link between verified practices at successive steps of the supply chain under the ASI Performance Standard, to the products produced by ASI Certified Entities.

How it serves the aluminium sector

The CoC Standard aims to support responsible supply chains by:

  • Providing a common standard for ASI Members in the Production and Transformation and Industrial Users membership classes, who wish to implement Mass Balance and/or Market Credits chain of custody systems in the aluminium value chain;
  • Establishing requirements that can be independently audited to provide objective evidence for the granting of ASI CoC Certification; and
  • Serving as a broader reference for the establishment and improvement of responsible production, sourcing and stewardship initiatives in metals supply chains.

The parts of the supply chain it covers

The ASI CoC Standard defines 3 key stages for the flow of CoC Material in supply chains. These stages involve quite different kinds of entities responsible for handling raw materials, metal production, and further fabrication and manufacturing to final products:

  • Primary Aluminium: Mine to Casthouse
  • Recycled Aluminium: Scrap to Casthouse
  • Post-Casthouse: Semi-fabrication and manufacturing to final product.

How it applies to members

ASI Members all share a commitment to the responsible production, sourcing and stewardship of aluminium, but have varied interests, considerations and priorities about the chain of custody of the aluminium they buy and sell.  The ASI Chain of Custody (CoC) Standard is therefore voluntary for ASI Members, though it is recommended as a way to add value to Certification against the ASI Performance Standard. (ASI Members in the Production and Transformation and Industrial Users membership classes are required to achieve ASI Performance Standard Certification against applicable requirements, for at least part of their operations within two years of joining ASI, whichever is later.)

However CoC Certification is mandatory for businesses that make any claims relating to production or sourcing of CoC Material, ASI Aluminium or ASI Credits, as defined under the ASI CoC Standard. Without CoC Certification, such claims cannot be made.
