Yes, consumers can access a tuna digital product passport before or at the point of purchase. When a brand enables this feature, a QR code printed on the packaging links directly to a verified digital record containing information about where the tuna was caught, how it was caught, which sustainability certifications apply, and how the product moved through the supply chain. The information comes from verified, real-time data rather than self-reported claims.
Most tuna labels tell you almost nothing about where your fish actually came from
A standard tuna label might list a species name, a country of origin, and a certification logo. But none of that tells you which vessel caught the fish, in which ocean zone, on which date, or under what conditions. For consumers who care about sustainability or labor practices, that gap is frustrating. A tuna digital product passport closes it by connecting the physical product to a digital record built from first-mile data captured at sea.
Unverified sustainability claims are eroding the trust that eco-labels were supposed to build
Certification logos have multiplied on seafood packaging over the past decade, but so has skepticism about what they actually mean. When a claim cannot be independently verified, it functions more as marketing than proof. A digital product passport changes the dynamic by making the underlying evidence accessible. Instead of asking consumers to trust a logo, it lets them inspect the data behind it.
What is a tuna digital product passport?
A tuna digital product passport is a structured digital record linked to a specific batch of tuna that documents its origin, catch method, handling journey, and verified sustainability and social compliance status. Consumers, retailers, and regulators can access it via a QR code on the packaging. Unlike a printed label, the passport draws on auditable, real-time data sources rather than static declarations.
The concept draws on the broader Digital Product Passport framework being developed within the EU as part of product-transparency regulation. For seafood, the format is particularly useful because the supply chain crosses multiple countries, vessels, and processing facilities before a product reaches a shelf. A tuna digital product passport may include the fishing vessel’s name and registration, the ocean zone and catch date, the fishing method, certifications held by the vessel and processor, and documentation related to crew welfare and labor standards.
What information can consumers see on a tuna digital product passport?
A tuna digital product passport may show catch location and ocean zone, the fishing vessel and method, sustainability certifications such as MSC or ASC, processing-facility records, and the supply-chain journey from vessel to shelf. Some passports also include social-compliance indicators related to crew welfare.
The specific data visible to consumers depends on what the brand has enabled for public display. More detailed records, such as vessel-tracking data or audit documentation, may be accessible to trade partners and regulators. Critically, each piece of information links back to a verified source rather than simply stating that one exists.
How does a QR code on tuna packaging connect to traceability data?
A QR code encodes a unique product identifier that, when scanned, retrieves the digital record associated with that specific batch. At port discharge, a unique Raw Material ID is assigned to the batch, linking it to vessel records, catch documentation, and verification data. As the product moves through processing and logistics, additional data points are added. By the time the QR code reaches the consumer, it references a complete, traceable history.
Platforms built on GS1 EPCIS and compatible with the Global Dialogue on Seafood Traceability (GDST) framework ensure that data captured at each supply-chain stage can be read and shared consistently, regardless of which systems different partners use.
How does a tuna digital product passport differ from a standard label?
A standard tuna label contains static, printed information that cannot be independently verified. A digital product passport is a dynamic, linked record that connects the product to verified source data. Labels are constrained by physical space and regulatory minimums, typically covering species, net weight, country of origin, and certification logos—none of it independently verifiable at point of purchase.
A digital product passport has no space constraint and ties its data to verifiable records. A certification claim links to the actual certification database. A vessel name links to satellite-tracking data. A catch location links to RFMO registry records. This moves the product story from declaration to documentation.
Why does first-mile traceability matter for consumer trust?
First-mile traceability captures data where the most significant supply-chain risks occur: at sea, during catch and transshipment. Most traditional traceability systems start at the processing facility, by which point fish from multiple vessels may have been combined and origin conditions can no longer be verified.
When traceability starts at the first mile using satellite-based vessel monitoring and real-time catch data, the record is built from events as they happen. For consumers reading a digital product passport, first-mile data is what separates a verified origin story from a marketing statement.
Which sustainability and social standards can a tuna passport verify?
A tuna digital product passport can verify a range of standards depending on certifications held by vessels and facilities in the supply chain. Common examples include MSC Chain of Custody, ASC certification, ISSF Participating Vessel Register status, and social-compliance frameworks such as BSCI/Amfori, SEDEX/SMETA, Fair Trade USA, and the FISH Standard for Crew.
Regulatory compliance data may also appear, including IUU blacklist checks, RFMO registry verification, and documentation supporting EU CATCH certificate requirements or US SIMP compliance. Including social-compliance data allows brands to substantiate ethical sourcing claims rather than simply asserting them.
How can brands and retailers use digital product passports to reduce risk?
Brands and retailers can use tuna digital product passports to build a verified, auditable record for every batch demonstrating legal catch, sustainable sourcing, and social compliance—available instantly for regulatory review, retailer audits, or consumer inquiries.
Without verified first-mile data, brands may not know what entered their supply chain until a problem surfaces downstream. A passport built on first-mile data provides early visibility: if a vessel appears on an IUU blacklist or a certification lapses, the system can flag the issue before the affected product moves further. For retailers, verified passports also serve a commercial purpose, as buyers increasingly require evidence of sustainable and ethical sourcing as a condition of doing business.
How SmarTuna supports tuna digital product passports
SmarTuna’s platform provides the infrastructure that makes a verified tuna digital product passport possible, starting from the moment a fishing trip begins. Here is what the platform delivers:
