The short version
- Certified products must never be mislabelled by species name under Clause 2.3.1 of the MSC Chain of Custody Standard.
- Species descriptions on physical packaging, invoices, and product specifications must align strictly with local market legislation.
- Certificate holders handling ASC-certified farmed seafood must maintain an up-to-date food fraud vulnerability assessment.
- Certification bodies use DNA sampling and product authentication testing to verify species identity and detect deliberate substitution.
Regulatory context and species mislabelling risk rationale
In global seafood supply chains, species mislabelling represents one of the most widespread forms of seafood fraud and commercial misrepresentation. Quality managers, compliance leads, and internal auditors must recognise that accurate species identification is essential to maintain consumer trust and protect the credibility of certified claims. Under the Marine Stewardship Council and Aquaculture Stewardship Council certification frameworks, mislabelling seafood species undermines supply chain traceability and creates severe legal and financial risks for businesses.
This regulatory framework affects processors, primary producers, importers, wholesalers, and multi-site group operations handling certified seafood. Using incorrect common or scientific names—such as confusing Pangasianodon hypophthalmus with Pangasius bocourti—can lead to audit non-conformities, market product recalls, or immediate certificate suspension. Understanding how species names are recorded in certificate scopes and verified during third-party audits ensures that organisations maintain full compliance across all traded product lines.
Species scope alignment and market legislation requirements
Under Clause 2.3.1 of the MSC Chain of Custody Standard: Default Version and Group Version, organisations must ensure that certified products are not mislabelled by species. Guidance 2.3.1 clarifies that while organisations may use either scientific or common names on product labelling and traceability records, the names used must align strictly with relevant legislation in the country where the seafood is traded. Furthermore, Clause 6.3.2(a) of the MSC Chain of Custody Certification Requirements v3.2 mandates that the certification body must explicitly define all certified species in the organisation's official database scope.
For organisations handling farmed seafood under the ASC Chain of Custody Module v1.1, species verification is integrated directly into broader food integrity controls. Under Clause 5.8.1 of the ASC Module, organisations must maintain a documented food fraud vulnerability assessment procedure and intervention plan covering all farmed seafood products. In addition, Part D of the ASC Module defines seafood fraud as the deliberate misrepresentation of products for economic gain, explicitly identifying species substitution and intentional mislabelling as high-risk fraudulent practices.
| Regulatory Domain | Normative Requirement | Standard / Clause Reference | Operational Audit Focus |
|---|---|---|---|
| Species Labelling Accuracy | Certified products shall not be mislabelled by species | MSC CoC Standard Clause 2.3.1 | Cross-checking packaging labels against scientific names |
| Statutory Alignment | Common and scientific names must comply with local laws | MSC CoC Standard Guidance 2.3.1 | Verifying species names against national market registers |
| Scheme Database Scope | Certified species must be defined in the CAB audit scope | MSC CoCCR v3.2 Clause 6.3.2(a) | Reconciling physical stock against database scope entries |
| Food Fraud Vulnerability | Maintain a food fraud assessment covering farmed seafood | ASC CoC Module Clause 5.8.1 | Reviewing VACCP or TACCP plans for substitution risks |
| Product Authentication | Allow CAB or MSC staff to collect samples for DNA testing | MSC CoC Standard Clause 5.5.2 | Collecting physical tissues for laboratory DNA verification |
Product authentication testing and audit verification protocols
To enforce species integrity across complex supply chains, certification bodies employ rigorous physical and analytical audit techniques. Under Clause 8.2.3 of the MSC Chain of Custody Certification Requirements v3.2, when a client is not actively handling certified products during an audit, auditors must inspect similar non-certified species to evaluate handling procedures. Furthermore, Table 5 of the Certification Requirements assigns elevated risk scores during audit planning when certified and non-certified products of similar-looking species are handled on the same site.
In addition to document verification, Clause 5.5.2 of the MSC Standard and Clause 5.5.2.1 of the ASC Module require organisations to grant auditors and designated agents access to collect physical seafood samples for DNA testing and product authentication. Under Guidance 7.4.10.b of the MSC General Certification Requirements v2.6, evidence of species mislabelling represents a critical supply chain failure that triggers automatic certificate suspension unless the organisation proactively self-reports the non-conformity and executes corrective action under Clause 5.4.1.
What to do now
- Audit all product packaging, specifications, and sales invoices to verify that common and scientific species names comply with destination market legislation under Guidance 2.3.1.
- Reconcile internal species purchasing catalogues against the official certified species scope registered on the scheme database under Clause 6.3.2(a).
- Conduct a food fraud vulnerability assessment covering species substitution risks for all farmed seafood items under Clause 5.8.1 of the ASC CoC Module.
- Train receiving and processing staff to inspect physical species characteristics and verify supplier traceability documents upon goods receipt under Principle 1 and Principle 2.
- Establish clear physical segregation and line clearance procedures whenever similar-looking certified and non-certified species are processed on shared equipment under Principle 3.
