A tuna digital product passport is a verified digital record linked to a tuna product that consumers and supply chain partners can access. It brings together data captured across the entire journey—from the fishing vessel to the store shelf—covering origin, fishing method, sustainability certifications, and social compliance. At the point of sale, it transforms a product label into a transparent, auditable story.
Unverified sustainability claims are eroding shopper trust faster than brands realize
When a can of tuna says “sustainably sourced,” most shoppers have no way to check whether that claim is true. Consumer skepticism about environmental labeling is growing, and brands that cannot back up their claims with verifiable evidence are quietly losing ground. The fix is not better marketing copy. It is connecting the product label to actual, auditable data captured at sea, at port, and at every stage of processing. A digital product passport does exactly that, turning a printed claim into something a shopper can verify in seconds.
Fragmented supply chain data is leaving brands exposed at the worst possible moment
Tuna crosses oceans, transshipment vessels, processing facilities, and multiple regulatory jurisdictions before it reaches a shelf. When documentation is manual and scattered, gaps appear—gaps that may not surface until an audit, a recall, or a regulatory inquiry. Moving to a unified digital traceability system that captures data from the first mile means the complete record already exists before anyone asks for it.
What is a tuna digital product passport?
A tuna digital product passport is a structured digital record linked to a specific batch or product unit that documents the full supply chain journey of that tuna. It typically includes origin data, vessel information, fishing method, sustainability certifications, and social compliance indicators. Consumers and trading partners can access it through the product code printed on packaging.
The concept builds on the broader Digital Product Passport framework, which aggregates data points that would otherwise sit in separate systems: satellite vessel-tracking records, port discharge documents, certification database checks, and social audit results. What makes a passport meaningful is the quality of the underlying data. Passports built on real-time, first-mile data capture provide a fundamentally different level of assurance than those assembled from post-processing paperwork.
How does a digital product passport reach the point of sale?
A digital product passport reaches the point of sale through a chain of data-capture events beginning when a fishing vessel departs and continuing through every supply chain stage. Each event adds a verified data layer to the product record. By the time the product is packaged for retail, the passport is already complete.
- Satellite VMS and AIS systems record vessel activity in real time throughout the fishing trip.
- At port discharge, a unique Raw Material ID is assigned to each batch, linking it to its origin, catch conditions, and verification criteria.
- The platform automatically checks that batch against regulatory and certification databases, including RFMO registries, IUU blacklists, and MSC Chain of Custody records.
- As the product moves through processing and logistics, additional data layers are added: facility records, social compliance audits, and shipment tracking.
- When packaged for retail, a QR code is applied giving consumers and retailers direct access to the full passport record.
What information does a shopper see?
When a shopper enters a product code, they typically see the product’s origin, the fishing vessel, the fishing method, the ocean area where it was caught, and any sustainability or social certifications that apply to that specific batch. Some passports also include catch date, port of discharge, processing facility details, and logistics records. The experience is designed to be accessible to a general consumer—translating technical verification data into plain, readable information.
How does the passport verify that tuna is sustainably sourced?
A digital product passport verifies sustainable sourcing by cross-referencing the batch’s origin and catch data against recognized sustainability certification databases and regulatory registries automatically. Verification may draw on MSC Chain of Custody records, ASC certification databases, ISSF ProActive Vessel Register data, and RFMO fishing authorization registries. This ties verification to the specific product in a shopper’s hand—a considerably stronger form of assurance than brand-level certification. Social sustainability data from programs such as the FISH Standard for Crew or SMETA audits may also be linked to the same batch record.
What role does the digital passport play in preventing IUU fish from reaching shelves?
A digital product passport helps prevent IUU (illegal, unreported, and unregulated) fish from reaching shelves by verifying the legal status of each vessel and catch at the point of data entry. Automated checks against IUU blacklists and RFMO registries flag non-compliant batches early. When vessel activity is recorded in real time via satellite and checked at port discharge, there is far less room for non-compliant catch to enter a legitimate supply chain undetected. Every handoff is documented, creating accountability across the chain. For brands and retailers, this also reduces compliance burden under frameworks such as EU catch documentation requirements and U.S. SIMP regulations.
How do retailers and brands benefit from a product passport at checkout?
Retailers and brands benefit by having instant, audit-ready documentation available for any product on their shelves. If a question arises about a specific product, the full traceability record is already assembled and accessible—no scramble to locate paper documents or reconstruct a chain of custody. Verified sustainability claims also carry more weight with retail buyers who conduct their own due diligence. A brand pointing to batch-level passport data is in a stronger negotiating position than one relying on a general supplier declaration. Shoppers who enter a product code and find transparent origin information may also develop stronger brand loyalty as a result.
What standards make a tuna digital product passport trustworthy?
A tuna digital product passport is trustworthy when built on internationally recognized data standards such as GS1 EPCIS and compatible with the Global Dialogue on Seafood Traceability (GDST) framework. GS1 EPCIS ensures data is structured consistently and interoperable across systems used by retailers, processors, and regulators. GDST compatibility adds a seafood-specific layer, defining what data should be captured at each supply chain stage and how it should be shared. Beyond technical standards, trustworthiness depends on data origin. A passport built on satellite-verified vessel tracking and automated checks against RFMO registries, ISSF PVR, and IUU blacklists is more reliable than one assembled from supplier-submitted documents.
