Supply Chain Data Collection for DPP

60-80% of Digital Product Passport data comes from your supply chain. This guide covers how to systematically collect and verify supplier data.

The Supply Chain Data Challenge

Most brands don't have direct relationships with all their suppliers:

• Tier 1: Direct suppliers (you know these)
• Tier 2: Suppliers' suppliers (you might know some)
• Tier 3+: Raw material sources (often unknown)

DPP requirements often need data from Tier 2 and beyond.

What Data Comes From Suppliers?

Material Data

• Raw material sources
• Material composition percentages
• Chemical treatments applied
• Recycled content verification

Manufacturing Data

• Production locations
• Process parameters
• Quality certifications
• Batch/lot tracking

Compliance Data

• Certifications (ISO, industry-specific)
• Test reports
• Audit results
• Regulatory compliance

Sustainability Data

• Carbon footprint contributions
• Energy sources
• Water usage
• Waste management

Data Collection Strategies

1. Supplier Questionnaires

Traditional but time-consuming:

• Create standardized forms
• Send to all suppliers
• Follow up repeatedly
• Verify responses

2. Automated Platforms

More efficient approach:

• Digital forms with validation
• Automatic reminders
• Data verification
• Audit trails

3. Integration with Existing Systems

Leverage existing data:

• ERP system data
• Certification databases
• Industry data pools
• Blockchain solutions

The Cascading Invitation Model

lnk.eco uses a cascading approach:

1. You invite Tier 1 suppliers

   • Enter their email and what they supply
   • They receive invitation to provide data

2. Tier 1 invites Tier 2

   • After completing their data, they invite their suppliers
   • Process continues down the chain

3. Data flows back up

   • All data connected to your products
   • Full traceability maintained

Data Verification

Supplier data needs verification:

Automated Checks

• Format validation
• Range checking
• Consistency across submissions

Documentation

• Request supporting documents
• Certification copies
• Test reports

Audits

• Third-party verification
• On-site audits for critical suppliers
• Random sampling

Data Access Tiers

Not all supplier data needs to be public:

Tier	Who Sees It	Examples
Public	Anyone	Material composition, recycling info
Restricted	Authorities	Supplier names, certifications
Confidential	Internal only	Pricing, exact processes

Common Challenges

Supplier Reluctance

• Concern about sharing proprietary info
• Resource constraints
• Language barriers

Solutions: Clear data protection policies, simplified forms, multilingual support

Data Quality

• Inconsistent formats
• Missing information
• Outdated data

Solutions: Validation rules, templates, regular updates

Tier 3+ Visibility

• Complex global supply chains
• Multiple intermediaries
• Changing suppliers

Solutions: Industry collaboration, certification programs, gradual improvement

Building Long-Term Capability

DPP data collection isn't a one-time project:

1. Start with priority products - Don't try to do everything at once
2. Build supplier relationships - Position as partnership, not burden
3. Invest in systems - Manual processes don't scale
4. Improve over time - Each product cycle gets better
