A digital product passport for tuna is a structured, verifiable digital record that travels with a product through every stage of the supply chain, from catch to shelf. It gives buyers, retailers, regulators, and consumers access to documented proof of origin, fishing method, sustainability certifications, and social compliance—all accessible through a QR code scan. For tuna specifically, this kind of verified documentation addresses some of the most persistent transparency gaps in the global seafood trade.
Scattered tuna documentation is putting your brand at risk
When traceability data is spread across paper logs, spreadsheets, and disconnected certification portals, the gaps become liabilities. A missing document at customs, an unverifiable sustainability claim, or a mislabeling incident traced to incomplete catch records can each trigger regulatory action or reputational damage. The fix is not more documentation—it is connected documentation. Centralizing supply chain data into a single, verifiable digital record means every claim is backed by evidence that can be checked instantly.
Manual catch records are holding back supply chain verification
Paper-based catch certificates were designed for a slower, simpler trade. Today, tuna moves through multiple vessels, transshipment points, processing facilities, and import markets before reaching a retailer. At each handoff, manual re-entry introduces errors that compound. A digital product passport replaces that chain of manual handoffs with a single thread of verified data. Shifting to digital capture at the first mile—before processing begins—is what makes the difference between a claim and proof.
What is a digital product passport for seafood?
A digital product passport for seafood is a structured digital record linked to a specific batch that documents its full supply chain journey. It typically includes origin data, vessel information, catch method, certifications, and compliance checks, stored in a standardized format and accessible via QR code.
Unlike a paper certificate that captures a single moment, a digital product passport accumulates verified data points across the entire chain. Each handoff—from vessel discharge to processing to export—adds another layer of documented evidence. In seafood, the passport format is increasingly aligned with international standards such as GS1 EPCIS and the Global Dialogue on Seafood Traceability (GDST) framework, ensuring data recorded by one supply chain partner can be verified by another.
Why does tuna traceability need a digital solution?
Tuna may be caught in one ocean, transshipped at sea, processed in a third country, and sold in a fourth. A single shipment may need to satisfy EU catch certificate requirements, US SIMP documentation, RFMO vessel registration checks, and MSC Chain of Custody verification simultaneously. Doing that manually is slow, error-prone, and difficult to audit.
Digital traceability solves this by capturing data at the source and propagating it automatically downstream. When a catch event is logged or a discharge recorded at port, that information becomes part of a verifiable record all authorized parties can access—no re-entry, no transcription error, no missing documentation.
What data does a tuna digital product passport contain?
A tuna digital product passport typically contains vessel identification, fishing location and date, catch method, species and weight, port of landing, sustainability certifications, social compliance records, and processing and logistics data. Each data point is linked to a specific batch and supported by verified documentation rather than self-reported claims.
At the catch level, the passport may include satellite VMS and AIS tracking data confirming where a vessel was operating, cross-referenced against authorized fishing zones and RFMO registries. Further down the chain, it accumulates certification records such as MSC Chain of Custody status, ISSF ProActive Vessel Register membership, and social audit evidence from frameworks such as SMETA, BSCI/Amfori, or the FISH Standard for Crew.
How does a digital product passport help prevent IUU fishing?
A digital product passport makes it much harder for illegally caught fish to enter a legitimate supply chain undetected. When every batch is linked to verified vessel data and cross-checked against IUU blacklists and RFMO registries, product from unauthorized sources has fewer places to hide.
IUU fish typically enters supply chains where documentation is weakest—during transshipment at sea or at ports with limited oversight. A passport that tracks from the first mile using satellite vessel monitoring closes many of those entry points. Automated checks against port lists and RFMO registries flag non-compliance in real time, shifting IUU prevention from a reactive audit exercise to a proactive screening process.
What’s the difference between a digital product passport and a catch certificate?
A catch certificate confirms a specific catch was legally made, typically required for import into jurisdictions such as the EU. A digital product passport is a broader, continuous record incorporating the catch certificate alongside vessel data, certifications, social compliance records, and logistics information.
The catch certificate answers one question: was this catch legal? The passport answers a wider set: where was it caught, by whom, under what conditions, with what certifications, and through which logistics chain? It is also consumer-accessible via QR code—something a traditional catch certificate was never designed to provide. A well-structured passport can incorporate catch certificate data and automate regulatory form completion, including EU CATCH and US SIMP requirements.
How can brands use a digital product passport to build consumer trust?
Brands can give shoppers direct access to verified sourcing information through a QR code on packaging. Instead of a vague sustainability label, consumers see documented evidence of where the tuna came from, how it was caught, and what certifications back the product.
Consumer skepticism toward seafood sustainability claims is well-founded. A digital product passport changes that dynamic by making verification visible. When a shopper scans a QR code and sees actual vessel data, certification IDs, and fishing locations, the claim becomes something they can evaluate. For brands, the digital record also provides auditable documentation if a claim is ever challenged—without assembling paperwork manually.
Who in the tuna supply chain should use a digital product passport?
Every stakeholder may benefit, including fishing companies, transshippers, processors, traders, importers, brands, and retailers. Fishing companies gain documented proof of legal operations to share with buyers. Processors and traders receive verified raw material data before taking ownership. Importers benefit from streamlined regulatory documentation. Brands and retailers gain the evidence needed to stand behind sourcing claims. Regulators and certification bodies can verify compliance without manual document submission from multiple parties.
