Companies that want to use the Marine Stewardship Council (MSC) ecolabel must obtain independent verification that the product originated from a certified fishery, which must be demonstrated by a CoC certificate held at each link in the chain. To use the MSC ecolabel companies must also have an MSC ecolabel license. The MSC CoC is an example of combining ‘one-up one-down’ traceability paper documentation and on the ground audits of traceability procedures and protocols.
