MSC Chain of Custody Standard (with ASC Module)
Ensuring the integrity of ASC certified supply chains and ASC labelled seafood, all the way to consumers.
ASC Chain of Custody (CoC) certificate holders are certified against the MSC CoC Standard – a traceability and segregation standard applicable to the full supply chain – and strengthened by the ASC module.
Chain of Custody certification, along with the ASC Label License Agreement, permits the use of the ASC label on the end product. This delivers traceability due diligence, de-risks seafood fraud in the supply chain and assures consumers that the seafood they choose comes from responsible ASC certified farms.
The Chain of Custody Standard
ASC uses the MSC Chain of Custody Standard to verify the origin of seafood sold as ASC certified or labelled. This process benefits companies that handle both ASC and MSC certified seafood by allowing them to do a combined audit.
ASC Module
ASC Chain of Custody certificate holders also need to meet the requirements of the additional ASC Module. The additional requirements address aspects specific to farmed seafood production, including food safety and antibiotic detection
Consumers look for the ASC label
According to independent research, the ASC label is the most recognised and trusted farmed seafood label, as well as having the highest association with sustainability and responsibility.
This makes it the perfect prompt for seafood shoppers to make the responsible choice.
