Demand for third-party certified, sustainably caught fish and seafood is increasing across the UK and Ireland. Consumers spent a record £1.5bn on products and menu items carrying the blue MSC ecolabel last year (2023/24), a 12% increase on the previous year and the largest jump during a single year since 2017/18-2018/19. 

If your business takes ownership of MSC certified seafood products and wants to sell them as certified, you need Chain of Custody certification.

The MSC Chain of Custody Standard provides assurance that all seafood sold with the blue MSC label comes from a fishery that has been certified as sustainable. 

This page provides all the information you need if you need to get your business certified against the MSC Chain of Custody Standard.
