A digital product passport for tuna is a structured digital record that captures and communicates verified information about a tuna product’s origin, journey, and compliance status. Consumers and buyers access it by scanning a QR code on the packaging, which pulls up data covering where the fish was caught, how it was caught, which certifications apply, and how the product moved through the supply chain from vessel to shelf.
Unverified sustainability labels are eroding buyer confidence faster than brands realize
When a sustainability claim on a tuna product cannot be backed by verifiable data, it creates a credibility gap that buyers and retailers are increasingly unwilling to accept. Procurement teams at major retailers now routinely request audit-ready documentation before onboarding suppliers, and companies that rely on supplier declarations rather than traceable records may find themselves cut from shortlists. A digital product passport replaces unverifiable claims with documented, data-backed proof that connects each product to its specific source.
Starting traceability at the processing stage leaves the riskiest part of the supply chain invisible
Most traceability systems only begin recording data once tuna reaches a processing facility, leaving the entire at-sea phase undocumented. That gap is where mislabeling, IUU catch, and labor violations are most likely to enter the supply chain. First-mile data capture, starting the moment a fishing trip begins, closes that gap and gives every downstream record a verifiable foundation.
What is a digital product passport for tuna?
A digital product passport for tuna is a data record linked to a specific batch or product unit that documents its full supply chain history. It includes origin data, fishing method, certifications, regulatory compliance checks, and handling records, typically accessed via a QR code on the product packaging.
Unlike a paper certificate or a static label, a digital product passport pulls together multiple layers of verified information into a single accessible record—including satellite tracking data, discharge records at port, certification IDs such as MSC Chain of Custody, and social compliance audit results. Each data point is tied to the specific batch, not just the supplier or brand.
Platforms built on GS1 EPCIS and compatible with the Global Dialogue on Seafood Traceability (GDST) framework generate passports that are interoperable across supply chain partners, allowing processors, retailers, and regulators to verify the same underlying data without proprietary systems.
What information does a tuna digital product passport include?
A tuna digital product passport typically includes catch origin, fishing vessel identity, fishing method, FAO zone, port of landing, certifications held at the time of catch, social compliance evidence, and chain of custody through processing and distribution. More detailed passports may also include:
- Satellite vessel-tracking records showing fishing location and activity
- Raw Material ID assigned at port discharge, linking the batch to its source before processing begins
- Verification against RFMO registries, the ISSF ProActive Vessel Register, and IUU blacklists
- Social audit results from frameworks such as BSCI/Amfori, SEDEX/SMETA, or the FISH Standard for Crew
- Regulatory documentation such as EU CATCH forms or U.S. SIMP records
How does a QR code connect consumers to tuna traceability data?
A QR code on tuna packaging links to a digital record stored on a traceability platform. Each product unit or batch is assigned a unique identifier during production, encoded in the QR code, and stored alongside all associated traceability records. When scanned, the platform retrieves and displays the relevant data in a readable format. Some passports show a simplified summary for consumers; others provide access to more granular data for buyers or regulators. The underlying record remains the same—the presentation layer adjusts to the audience.
How is tuna traceability data captured at sea in real time?
Tuna traceability data is captured at sea using satellite-based Vessel Monitoring Systems (VMS) and Automatic Identification Systems (AIS), which record vessel location, movement, and fishing activity continuously. VMS transmits vessel position at regular intervals via satellite; AIS provides complementary tracking visible to a broader range of monitoring systems. Together, they verify that fishing occurred in authorized zones.
At port discharge, a unique Raw Material ID is assigned to each batch, digitally linking it to the vessel’s at-sea records before processing begins. Some platforms also incorporate electronic monitoring (EM) systems and observer reports, adding independent verification of fishing activity and crew conditions that strengthens any downstream compliance claims.
What’s the difference between a digital product passport and a sustainability certificate?
A sustainability certificate confirms that a product or operation meets a defined standard at a point in time. A digital product passport is a dynamic, batch-level record documenting the actual journey of a specific product, including real-time data, regulatory checks, and certifications. The passport contains the certificate as one data point among many.
Certificates such as MSC Chain of Custody confirm that a company has systems in place to handle certified product correctly—but do not specify which vessel caught a particular batch or whether that vessel operated in an authorized zone. A digital product passport ties the certificate to a specific batch and supplements it with at-sea data, discharge records, and regulatory checks, giving buyers a much stronger evidentiary position when a product is questioned.
Who benefits from a digital product passport in the tuna supply chain?
Every party in the tuna supply chain benefits differently. Fishing companies gain documented proof of compliance. Processors and traders reduce audit preparation time. Retailers verify supplier claims before listing products. Regulators access structured data for enforcement. Consumers get transparent information about what they are buying.
When regulatory forms such as EU CATCH certificates or U.S. SIMP records are generated automatically from the same underlying data, administrative burden decreases across the supply chain. For consumers, scanning a QR code surfaces specific details—ocean area, certification status, labor practices—rather than a generic sustainability statement.
How does a digital product passport help prevent IUU fishing and forced labor?
A digital product passport creates a verifiable, batch-level record connecting each product to its at-sea origin. Real-time vessel tracking, automated checks against IUU blacklists and RFMO registries, and integrated social compliance data make it significantly harder for non-compliant catch to enter the supply chain undetected.
First-mile data capture assigns a verified identity to each batch at port discharge—before processing—based on satellite records of vessel activity. Forced labor risk is addressed through satellite analytics that flag behavioral patterns such as extended at-sea periods, combined with electronic monitoring, observer reports, and social audit certifications. Automated checks against 15+ regulatory databases run continuously and flag non-compliant vessels before their catch progresses further.
