Supply Chain Traceability for DPPs
EUDR, CSDDD, EPCIS, and chain-of-custody for high-risk materials — the traceability stack behind every credible DPP.
Why Traceability Has Become a Strategic Imperative
Supply chain traceability used to be a nice-to-have for sustainability marketing. It is now a compliance, risk-management, and consumer-trust imperative. From the EU Deforestation Regulation to the Corporate Sustainability Due Diligence Directive, regulators are demanding that brands know their suppliers and stand behind their products' origins.
Digital Product Passports are the consumer-facing layer of this traceability stack — the place where verified supply chain data is finally exposed to the people buying the product.
- EUDR requires deforestation-free supply chain due diligence
- CSDDD mandates human rights and environmental due diligence
- Consumers increasingly distrust unverified sustainability claims
- DPPs are the consumer-facing layer of supply chain truth
From Tier 1 to Tier N: Mapping the Chain
Most brands know their Tier 1 suppliers well. Visibility drops sharply at Tier 2 and is often non-existent at Tier 3 and beyond. Yet many of the highest sustainability and human-rights risks live deep in the chain — in fabric mills, mineral mines, and raw material processors.
DPP-grade traceability requires mapping these tiers, contractually requiring data flow, and verifying it through audits or independent data services.
- Tier 1: direct suppliers — high visibility
- Tier 2-3: fabric mills, component makers — partial visibility
- Tier 4+: raw material sources — low visibility, high risk
- Contractual data-flow requirements bridge the gap
EPCIS and the Standardisation of Supply Chain Events
EPCIS (Electronic Product Code Information Services) is the GS1 standard that defines how supply chain events should be captured and shared. Every event — manufactured at facility X, shipped to warehouse Y, delivered to retailer Z — can be recorded in a standardised format.
When these events flow into the DPP, consumers and regulators see a verifiable journey rather than a marketing story.
- Standardised event capture across the chain
- Interoperable with WMS, ERP, and logistics systems
- Auditable trail for regulators and certifying bodies
- Consumer-facing journey visualisations powered by EPCIS data
Note
SmartLinks ingests EPCIS-compatible event streams and renders them as consumer-friendly journey timelines on every product page.
Chain-of-Custody for High-Risk Materials
Some materials require special chain-of-custody discipline: cotton, palm oil, leather, cocoa, conflict minerals, timber. Certification schemes (Fair Trade, RSPO, Rainforest Alliance, RJC, FSC) provide standardised frameworks.
DPPs can carry certification IDs that are independently verifiable, ending the era of unverifiable label claims.
- Certification IDs linked to issuing bodies
- Independent verification at consumer scan
- Batch and lot-level granularity where available
- Audit trails for regulators and NGOs
Provenance Storytelling Without Greenwashing
Consumers want to believe brand sustainability stories but increasingly know to question them. DPPs let brands tell richer stories backed by verifiable data — a powerful counter to the rising regulatory and reputational risk of greenwashing.
The rule is simple: claim only what the data supports, and make the data accessible. Connected packaging is the perfect channel.
- Verifiable claims tied to source data
- Compliance with the EU Empowering Consumers for the Green Transition Directive
- Avoid greenwashing fines and reputational damage
- Audience-aware: consumers see story, regulators see evidence
Implementing Traceability with SmartLinks
SmartLinks acts as the consumer-facing layer over your traceability stack. It ingests data from PIM, ERP, EPCIS, and third-party certification services, then renders it in formats appropriate to each audience — story for consumers, evidence file for regulators, data feed for retailers.
Brands keep their existing back-office systems; SmartLinks handles the product-level identity, the scan, and the resolution.
- Integrates with PIM, ERP, and EPCIS data sources
- Audience-aware rendering: consumer / regulator / retailer
- Verifiable certification IDs resolved at scan
- API-first architecture for ongoing data refresh
