A tuna digital product passport (DPP) is a structured digital record that stores verified data about a tuna product’s origin, supply chain journey, sustainability credentials, and social compliance information. Consumers and buyers access it through a QR code on the product packaging, which links to a verified record built from real-time data captured at every stage—starting with the fishing vessel itself.
Relying on paper documentation is holding back supply chain trust
Traditional tuna supply chains depend heavily on paper certificates, manual data entry, and documents assembled after the fact. When a buyer or regulator asks for proof of origin or sustainability, companies often scramble to pull records from multiple sources—and gaps appear. Those gaps create real exposure: product recalls, mislabeling claims, regulatory violations, and lost contracts with retailers that now demand verified sourcing. The fix is shifting from document assembly to continuous data capture, where verification happens at the source and accumulates automatically throughout the chain.
Unverified sustainability claims may be costing you retailer relationships
Retailers and major buyers increasingly require more than a supplier’s word on sustainability. When a brand makes a claim it cannot substantiate with auditable data, it risks losing shelf space, facing legal challenges, or being named in IUU-related investigations. What matters is moving from declaration-based sourcing to evidence-based sourcing—where every claim about catch method, fishing area, and certification status is backed by a verifiable digital record that auditors and buyers can inspect independently.
What is a digital product passport for tuna?
A tuna DPP is a structured digital record linked to a specific batch or product that stores verified data about origin, fishing method, handling, certifications, and supply chain journey. It is typically accessible via a QR code and built on standardized data formats so information can be shared and verified across supply chain partners.
Unlike a static label or paper certificate, a tuna DPP is dynamic and traceable. It pulls together data from multiple points—the fishing vessel, port of discharge, processor, and logistics chain—into a single accessible record, verified against regulatory databases and certification registries. The concept is gaining traction partly because of regulatory momentum in the EU and US, where import controls and traceability requirements are becoming more detailed.
What supply chain data does a tuna digital product passport contain?
A tuna DPP typically contains origin data (vessel name, flag state, fishing area, FAO zone), catch date and method, port of discharge, batch identification, processing facility details, logistics records, and applicable certifications. The most complete DPPs start at the first mile—data collection begins the moment a fishing trip starts, not when the product enters a processing facility. This may include satellite-tracked vessel position data from VMS and AIS systems, providing an independently verifiable record of where and how the fish was caught.
At port discharge, a unique Raw Material ID is assigned to each batch, linking all origin and catch data to that specific lot before processing begins. From that point, the DPP accumulates additional records: processing steps, weight and composition data, cold chain information, and final product codes.
How does a tuna digital product passport verify sustainability claims?
A tuna DPP verifies sustainability claims by cross-referencing supply chain data against recognized certification registries and regulatory databases—such as MSC Chain of Custody records, RFMO vessel registries, and ISSF ProActive Vessel Register listings—rather than relying on supplier declarations alone.
Automated checks against IUU blacklists, PSMA port approval lists, and EU-approved facility registries flag inconsistencies before they become compliance problems. Platforms integrating 15 or more databases can run these checks continuously as data enters the system, meaning sustainability information in a DPP is substantiated by external verification at multiple points—not simply asserted.
What labor and social compliance information is included in a tuna DPP?
A tuna DPP may include social compliance certifications such as amfori BSCI, Sedex SMETA, Fair Trade USA, and the FISH Standard for Crew, along with electronic monitoring reports and forced labor risk indicators derived from vessel activity patterns. Satellite analytics can identify behavioral patterns signaling forced labor risk—such as extended time at sea, unusual transshipment activity, or vessels operating in areas inconsistent with their reported fishing zones.
When social-audit evidence and observer data are attached to the same Raw Material ID as catch and origin data, buyers and retailers get a complete picture of the product—not just where it came from, but under what conditions. This matters increasingly to retailers facing due diligence obligations under emerging supply chain transparency regulations in the EU and Germany.
How is tuna digital product passport data accessed?
Consumers access tuna DPP data by scanning a QR code on the product packaging, which links to a record showing origin, sustainability credentials, and the supply chain journey. The consumer-facing view is a simplified summary—fishing area, catch method, certifications, and sometimes a visual map of the vessel’s journey. The underlying record contains the full verified dataset that auditors, retailers, and regulators may need.
For business-to-business sharing, platforms built on GS1 EPCIS standards and compatible with the Global Dialogue on Seafood Traceability (GDST) framework allow data to flow between supply chain partners in a consistent, machine-readable format—without custom integration work for each trading relationship.
What’s the difference between a tuna DPP and traditional traceability documentation?
Traditional traceability documentation consists of paper or PDF records—catch certificates, health certificates, customs forms—that are often incomplete, manually entered, and difficult to cross-reference. A tuna DPP is a continuously updated digital record built from verified, real-time data captured at each stage. Traditional documentation tends to be retrospective; a DPP records events as they happen using satellite tracking, automated database checks, and digital document storage. It also makes information available instantly, in a standardized format, to anyone with appropriate access—whether a regulator, retailer, or consumer scanning a QR code.
Who needs a digital product passport in the tuna supply chain?
Any company that buys, processes, imports, sells, or brands tuna products may benefit from DPP capabilities. Fishing companies and traders need it to demonstrate legally sourced, sustainably certified catch when selling into markets with strict import controls. Processors and importers need it to manage compliance with the EU Catch Documentation Scheme, US SIMP, and US FSMA. Brands and retailers need it to substantiate sustainability and ethical sourcing claims—as due diligence legislation expands, auditable batch-level evidence is becoming a practical business requirement, not just a differentiator.
