Between the ocean and your plate, fish and seafood products may pass through many stages. Supply chains can be very complicated. The MSC Chain of Custody Standard ensures that products from MSC certified sustainable fisheries are traceable and separated from non-certified products

Why certify supply chains?

Seafood products can pass through long and complex supply chains between the ocean and reaching consumers. At each stage, there is a risk that products will be mislabelled or that products from an MSC certified fishery will be mixed up with non-certified products.

Certification to the Chain of Custody Standard ensures an unbroken chain where certified seafood is easily identifiable, separated from non-certified products, and can be traced back to another certified business. 

This system allows businesses and consumers to be confident that seafood with the blue MSC label has come from a fishery certified as sustainable. 

Across the UK and Ireland, there are currently over 280 certificate holders and 147 licence holders.
