Chain of Custody Standard

ASC is conducting a second consultation on the ASC Chain of Custody (CoC Module) Review

Following a successful preliminary consultation in 2025 (summary report available here), ASC is launching a second consultation on the revision of the ASC Chain of Custody (CoC) Module.

The revised ASC CoC Module will be known as the ASC Supply Chain Module to reflect its wider scope beyond traceability. This consultation will run for 60 days from 2 March 2026. We are consulting on proposals in relation to:

1. Human rights
2. Humane slaughter
3. Amendments to food safety
4. Other changes to traceability and conformance
5. The ASC Supply Chain Module document

Please submit your feedback through the consultation survey.

This slide deck contains background information and explain proposals on the consultation topics. This resource is available in other languages below. 

The complete ASC Supply Chain Module draft is available here.

On 23 March, ASC will also host two online Q&A sessions, giving you the opportunity to ask questions you may have to our expert team.

• Sign up here for the Q&A at 10:00 UTC (Asia-friendly timing)
• Sign up here for the Q&A at 17:00 UTC (Americas-friendly timing)

Human rights proposals include certificate holders implementing an ASC Human Rights Code of Conduct and publishing a human rights policy. This proposal involves specific responsibilities for CABs and auditors.

In terms of humane slaughter, ASC proposes to apply specific ASC Farm Standard requirements to slaughter when it is conducted in the post-farm supply chain.

ASC further proposes to maintain the food safety requirement with specific amendments, and make improvements to traceability and conformance.
MSC is also currently reviewing its CoC Standard with a 60-day public consultation opening in mid-March.

Further resources are available for the current stakeholder consultation:

• • Project Terms of Reference
  • Offline version of the survey questions
  • Slide deck with background information in French

In May – June 2025, we held a preliminary stakeholder consultation on the Module revision. We received over 100 responses from stakeholders across the world, on topics including:   

• The revision project Terms of Reference  
• How to tackle human rights issues in the supply chain 
• The inclusion of humane slaughter requirements 
• Other topics such as food safety, digital traceability and ASC improver products 

Please see here the summary report summarising the stakeholder feedback and ASC response.

A further 60-day consultation will be conducted starting in March 2026 on the specific proposals to develop the revised ASC CoC Module.

Inclusion of human rights requirements for companies in the supply chain

• MSC has removed the option for companies with a Chain of Custody certificate to undergo third-party labour audits as a way to meet MSC CoC requirements;
• Our vision and mission includes social as well as environmental responsibility, across feed, farms and companies processing and selling seafood in the supply chain;
• To align with social requirements across our programme, ASC is committed to including human rights requirements for companies in the post-farm supply chain – an important focal point for the ongoing ASC Chain of Custody (CoC) Module review process;
• We recognise that announced social audits, in isolation, do not provide a solution to all human rights issues in supply chains but are one ‘tool in the box’ in assisting businesses to demonstrate social responsibility;
• We believe a layered approach is required, incorporating a number of measures, to deliver overarching assurance on human rights compliance;
• Our updated and improved ASC CoC Module release, as outlined above, is planned for November 2026 with an effective date in May 2027 aligned with the effective date of the ASC Farm Standard.
• In the interim period prior to the revised ASC CoC Module effective date, MSC labour requirements will continue to apply to ASC CoC certificate holders.
