What Is ASC Chain of Custody Certification?

ASC Chain of Custody Certification

Chain-of-custody certification for qualifying farmed seafood sold with Aquaculture Stewardship Council claims. This certification documents and verifies the path of ASC-certified aquaculture products from the certified farm through processing, distribution, retail, and final sale so that the ASC claim on pack or in marketing is accurate and defensible.

The certificate applies to any organisation that physically handles, processes, trades or sells ASC-labelled farmed seafood. It does not certify farming practices themselves (that is the farm-level ASC certification) but ensures that product segregation, record-keeping and labelling at every step preserve the integrity of ASC claims. The standard is used by processors, distributors, wholesalers and retailers that want to market ASC-certified products to consumers.

What The Certification Covers

The ASC chain-of-custody framework defines the operational, documentation and verification requirements organisations must meet. Typical elements include:

• Scope: Which products, brands, sites and SKUs the certificate covers and any exclusions or site-specific limitations.
• Segregation: Physical or procedural controls to keep ASC product separate from non-certified product during receiving, storage, processing and dispatch.
• Traceability Records: Documentation of purchase invoices, transfer notes, packing lists and sales that link product lots to ASC-certified suppliers and onward customers.
• Labelling And Claims: Controls over how ASC logos and claims can be used on packaging, menus and marketing materials.
• Audit And Verification: Requirements for third-party audits, corrective actions and maintaining certificate validity.

Why It Matters To Retailers

Retailers rely on chain-of-custody certification to offer credible sustainable seafood claims to consumers without auditing farms directly. An ASC chain-of-custody certificate reduces reputational risk by ensuring that the seafood on the shelf actually originates from ASC-certified farms. It also simplifies supplier management by creating a single verified point of assurance that a supplier’s handling practices meet ASC requirements.

How Certification Typically Works

Organisations apply to an accredited certification body that conducts an initial assessment of procedures, records and site practices. The process normally includes a documented system review, on-site inspection of facility flows and interviews with staff, and review of traceability records such as supplier invoices and production logs. If non-conformities are found, corrective action plans are required before a certificate is issued.

How It Varies By Business Type

Requirements differ by the role a business plays in the supply chain. Examples:

• Processor: Strong segregation at production lines and batch-level records to prevent commingling.
• Distributor: Warehouse segregation, lot tracking, and clear invoicing linking inbound ASC lots to outbound shipments.
• Retailer: Point-of-sale labelling controls and marketing approvals to prevent misuse of ASC claims.

Common Documentation And Systems

Retailers should expect to maintain and produce:

• Supplier Contracts: Agreements specifying ASC supply and responsibilities for record retention.
• Batch Records: Lot numbers or internal codes that link shelf product to supplier certificates and invoices.
• Receiving And Dispatch Logs: Dates, weights, product descriptions and reference numbers for traceability checks.

Practical Example

A mid-sized supermarket sources ASC-certified shrimp. The retailer’s buying team keeps a database of approved ASC suppliers and requires supplier invoices to carry ASC certificate numbers. Warehouse staff store ASC lots on designated racks and scan inbound pallets into the ERP/WMS with batch numbers. When the store sells an ASC-labelled pack, the POS SKU links back to the batch in the system so an audit trail is available showing the certified farm, the processor and the distribution lots.

Tips For Retailers Considering Certification

• Start With High-Volume SKUs: Focus certification efforts where sustainability claims matter most to customers and where traceability is practical.
• Integrate Systems: Use WMS/ERP and barcoding to reduce manual record-keeping errors and streamline audits.
• Train Staff: Ensure receiving, merchandising and marketing teams understand segregation, labelling rules and documentation needs.

In short, the ASC Chain of Custody Certification provides the documented, auditable link between ASC-certified farms and retail sales, enabling credible use of ASC claims while managing operational and reputational risk for retailers and their suppliers.
