CERTIFICAZIONE MSC™ – Marine Stewardship Council™

The Marine Stewardship Council™ (MSC™) is an international non-profit organization, founded in 1997 to address the problem of unsustainable fishing and to conserve fish and seafood stocks for the future.

The MSC certification is the main global seafood certification scheme for sustainable fishing at international level. It is a voluntary certification open to all companies involved in fishing. It is based on a sustainable fishing standard and a traceability mechanism for fish products. The system contributes in a responsible way to better management and conservation of fish stocks worldwide.

The Marine Stewardship Council has developed two different standards, the first for fishing companies and the second for companies that process and/or market MSC-certified seafood products and must therefore ensure product traceability along the chain of custody.

  • The MSC Sustainable Fisheries Standard certifies fish stocks and is based on three main principles (and 31 criteria) concerning the preservation of fish stocks, the impact of fishing operations and compliance with regulations. The certified organisation must demonstrate that it implements good management practices ranging from monitoring activities to assessing impacts. The fisheries certification process is a public process, managed by highly qualified and experienced auditors. For further information, please visit www.msc.org.
  • The MSC Chain of Custody standard guarantees the traceability of MSC-certified seafood products (fish, shellfish, molluscs, etc.) throughout the product processing, processing and distribution chain. All companies in the chain that intend to handle or sell MSC-certified fished products must hold a Chain of Custody certificate. The MSC and ASC (for sustainable aquaculture) certification schemes share the same chain-of-custody standard. This allows companies to manage a double certification in a convenient and practical way by following the rules of a single standard.

Thanks to the Chain of Custody, the end product can be labelled and consumers can choose fish products (fish, shellfish, molluscs…) caught in a sustainable and responsible manner.

The MSC certification scheme is third-party. Vireo is an independent certification body accredited by ASI (Assurance Services International) to conduct audits and issue MSC certificates (ASI-ACC-086).


MSC certificates are valid for 3 years with an annual inspection.

When the company is ready, Vireo plans a first certification audit (Main Assessment). In this phase all the information is collected and, if everything is in order, the certificate is issued a few days later. The company must indicate the MSC certified fish species and the certified suppliers that have been identified.

The standard consists of five principles.

1) Certified products must be purchased from certified suppliers

2) Certified products must be identifiable

3) Certified products must be kept separate

4) Certified products must be traceable and volumes must be recorded

5) The organization must have a management system.

The main aspects are registration (traceability) and correct identification and separation.

All enterprises who acquire legal ownership of the MSC product, even without physical possession, and want to resell it as such should be certified Some specific exceptions to this general rule are described in the MSC chain of custody standard.

Yes, both MSC and ASC schemes share the same chain of custody standard. Companies can therefore opt for a dual MSC and ASC certification.

  • Principle 1: Sustainability of the fish stock

The fishing activity must be carried out in compliance with the sustainability of the existing fish stocks. Any certified fishing company must operate ensuring the conservation of species and avoiding the overfishing of stock.

  • Principle 2: Minimal environmental impact

Fisheries must preserve the structure, productivity, functions and diversity of the ecosystem.

  • Principle 3: Effective Management

Companies in the seafood sector must comply with all local, national and international laws and regulations, setting up a management system that allows them to adapt to changing circumstances and ensure sustainability.

MSC/ASC chain of custody standard

The MSC and ASC chain of custody certificationguarantees the traceability of MSC certified seafood products. It is based on a standard of traceability and segregation that is applicable to the entire production chain.

Chain of custody is based on some general aspects such as:

  • The definition of roles and responsibilities,
  • verification of MSC or ASC raw material supplies
  • Proper segregation of raw material in the warehousing stages and in the processing and manufacturing stages
  • Records management (input quantities, processed, transformed, etc.)
  • sale and labeling of finished product

The focus of certification is therefore to pursue the non-mixing of MSC or ASC product with non-certified product.

Chain of Custody MSC and ASC certificates are valid for 3 years. During this period, the performance of companies must be examined to see that they continue to meet the MSC and ASC standards. After 3 years the company must be completely reexamined if it wishes to remain in the MSC and ASC program.


Only certified companies can put the MSC or ASC mark on certified products and also use it for promotion. The MSC and ASC logos are registered trademarks whose use is granted, subject to payment of fees, by MSC International.
The MSC label on the product means that the fish comes from sustainable fisheries, while ASC-labeled products come from responsible fish farms.



This document describes the requirements that each company must apply in order to obtain MSC/ASC certification. The standard was updated during 2019 and is valid for all companies as of September 28, 2019.
