With a complex international supply chain for many seafood products, substitution and mislabelling of seafood is a globally-recognised issue. The Chain of Custody Standard is a traceability and segregation standard that is applicable to the full supply chain from a certified farm to the product carrying the ASC logo.

Each company in the supply chain handling or selling an ASC certified product must have a valid Chain of Custody certificate. This assures consumers and seafood-buyers that ASC labelled products come from a certified responsible farm.

We use the Marine Stewardship Council’s (MSC) Chain of Custody (CoC) Standard to verify the origin of seafood sold as ASC certified. This process benefits companies that handle both ASC and MSC certified seafood by allowing them to do a combined audit, although separate certificates are issued.

  • In May 2022, ASC introduced the ASC CoC Module, which becomes effective on May 30, 2023, and will apply in addition to the MSC CoC requirements. More information on the CoC Module development process is available here.
  • The ASC CoC Module v1.0 scheme document and supporting materials can be found under Documents in the column to the left.  

The traceability requirements are established in three variants to service a diverse range of companies:

  • Default
    Applicable to single or multi-site company that is handling or trading certified products
  • Group
    Applicable to any organisation handling certified products at multiple sites, where each site is controlled and monitored by a head office
  • Consumer-Facing Organisation
    Applicable to most companies of any size that sell directly to final consumers

More information about the different variants, eligibility and easy guidelines on how to get started can be found under Get Certified! Chain of Custody guidelines.
