A digital product passport for tuna is a structured digital record that documents a product’s full journey from catch to shelf. It stores verified data about where and how the fish was caught, which vessel was involved, what certifications apply, and how the product moved through the supply chain. Consumers and buyers can access this information through a traceability code on the product packaging, making sourcing claims verifiable rather than merely asserted.
Unverified sourcing claims are putting tuna brands at legal and commercial risk
When a tuna product carries a sustainability label without documented, auditable proof, the brand is exposed. Regulators in the EU and US have strengthened seafood documentation requirements, and companies that cannot substantiate sourcing claims risk recalls, import rejections, or reputational damage. The fix is a shift from supplier declarations to verified, first-mile data that travels with the product from the moment it is caught.
Starting traceability at the processing stage leaves your supply chain blind at the point that matters most
Most seafood documentation begins after the fish has been processed, meaning the most critical events—where and how the fish was caught, which vessel was used, and whether it was operating legally—are never independently verified. By the time a problem surfaces, the product has already passed through multiple hands. Tuna brands that want genuine supply chain confidence need traceability that starts at sea, not at the factory gate.
What information does a tuna digital product passport contain?
A tuna digital product passport typically contains vessel identification, catch location and date, fishing method, species and stock information, sustainability certifications, chain-of-custody records, and social compliance data. It may also include processing facility details, batch identifiers, and regulatory documentation such as catch certificates.
Passports generated from first-mile data—captured at sea using satellite tracking systems such as VMS and AIS—carry far more verifiable detail than those assembled from post-processing paperwork. A strong digital product passport links each batch to a unique Raw Material ID before processing begins. On the social side, it may also reference labor-compliance indicators, including crew welfare certifications such as the FISH Standard for Crews or audit frameworks like SMETA.
How does a digital product passport work in the tuna supply chain?
A digital product passport assigns a unique digital identifier to each batch of tuna at the point of origin, then links that identifier to verified data at every subsequent stage. In practice:
- A fishing vessel is monitored in real time via satellite VMS and AIS, recording location, activity, and catch data at sea.
- At port discharge, a unique Raw Material ID is assigned to the batch, digitally linking it to its origin and verification criteria before processing begins.
- Each subsequent stage—processing, transshipment, and logistics—adds verified records to the batch’s digital profile.
- Certifications and regulatory checks are validated automatically against databases such as RFMO registries, MSC Chain of Custody records, and IUU blacklists.
- The completed passport is accessible via a traceability code, giving consumers, retailers, and regulators instant access to the product’s fully documented story.
Why does tuna need a digital product passport?
Tuna’s supply chain is one of the most complex in the food industry. Fish may be caught across multiple ocean zones, transshipped at sea, processed in one country, and sold in another—creating documentation gaps that paper-based systems cannot reliably close. Without verified proof of origin, tuna products may inadvertently include IUU catch. Authorities in the EU and US require detailed catch documentation as a condition of import, and companies that cannot provide it face shipment delays, rejections, or legal exposure. A digital product passport also allows brands to substantiate sustainability and ethical sourcing claims with verifiable data rather than unproven labels.
What’s the difference between a digital product passport and a sustainability certificate?
A sustainability certificate, such as MSC or ASC, confirms that a fishery or facility meets defined standards at the time of audit. A digital product passport is a product-level record documenting the specific journey of a particular batch, including whether it came from a certified source and what happened along the way.
Certificates apply broadly to a fishery or operation and do not follow individual batches. A digital product passport is batch-specific and dynamic, accumulating verified data at each stage to connect a specific product on a shelf to a specific vessel in a specific ocean. The two are complementary: a certificate may be one data point within a passport, but the passport adds chain-of-custody records, regulatory compliance checks, and social accountability evidence that a certificate alone cannot provide.
Who benefits from a tuna digital product passport?
Multiple parties benefit. Brands and retailers gain documented proof to substantiate sourcing claims and reduce legal exposure. Buyers benefit from reduced risk of selling mislabeled or non-compliant products and simplified supplier audits. Fishing companies and processors can demonstrate compliance more efficiently and strengthen commercial relationships. Consumers gain genuine transparency—a traceability code-accessible passport lets shoppers verify sustainability and ethical sourcing claims for themselves, building stronger brand loyalty among buyers who care about where their food comes from.
How can tuna brands implement a digital product passport?
Tuna brands can implement a digital product passport by adopting a traceability platform that captures verified data starting at the first mile, assigns unique batch identifiers at port discharge, integrates with regulatory and certification databases, and generates consumer-accessible records via traceability code. The platform should be built on recognized standards such as GS1 EPCIS and be compatible with GDST requirements.
Implementation works best when data collection starts before processing. Brands should look for systems that automate compliance checks across multiple databases, store verification documents per batch, and support regulatory documentation for target markets, including EU CATCH certificates and US SIMP forms.
