Submitting a complaint

The MSC welcomes your feedback as it helps us improve our program. Depending on what you would like to tell us, there are different ways you can give feedback or register a complaint.

What is your complaint regarding?


An MSC certified fishery

If you believe an MSC certified fishery is engaged in unsustainable fishing, please contact the certification body who assessed that fishery. To find the certification body and their contact details, search for the fishery of interest using the MSC Track a Fishery website.



An MSC labelled product

If you have found something wrong with an MSC labelled fish or seafood product, please contact the brand or supplier of that product.



A fishery seeking MSC certification

If you have a complaint about a fishery seeking certification, please contact the certification body conducting the fishery’s MSC assessment and register yourself as a stakeholder. For more information on the assessment and objection process, see how to engage with a fishery assessment.


Conduct of a certification body

If you’re concerned that a Conformity Assessment Body (CAB) has not acted impartially in their assessment of a fishery, please direct your feedback to Assurance Services International (ASI), the independent body who oversees certification bodies.



Feedback on the MSC Standards

You can participate in the development of the MSC Fisheries Standard or the Chain of Custody Standards. Visit our Program Improvements website to see how we are currently developing our Standards. You can also read more about our Fisheries Standard Review and Assurance Review to find out how you can participate in Standard development.
