Getting Started
Welcome
tieback Knowledge is a practical, neutral reference library for Digital Product Passports (DPPs), product traceability and European Union product compliance. It exists to help you understand what the law actually requires, what is still being decided, and what that means for the products you make, sell, certify or regulate.
The subject moves quickly. Framework regulations are already in force, while much of the detail arrives later through delegated acts, harmonised standards and sector guidance. This library is written to keep those two layers clearly separated, so you can plan with confidence and avoid building on assumptions that have not yet been settled in law.
Who This Knowledge Base Is For
The content is written for professionals who need accurate, working knowledge rather than headlines:
- Manufacturers placing products on the EU market and preparing for passport obligations.
- Product owners deciding what product data must exist, and who owns it.
- Compliance professionals tracking legal obligations, deadlines and evidence requirements.
- Sustainability teams working on circularity, durability, repairability and material data.
- Supply chain teams collecting and verifying data from suppliers and contract manufacturers.
- Technology teams designing identifiers, data carriers, data models and integrations.
- Consultants advising clients on readiness, scope and implementation sequencing.
- Regulators and policy professionals looking for a plain description of how the pieces fit together in practice.
No prior familiarity with ecodesign law is assumed. Where a term matters, it is defined, and the Glossary holds the definition of record for every recurring term used across the library.
What You Will Find Here
The library is organised into categories so you can either read a topic end to end or use it as a lookup reference.
- Digital Product Passports: what a passport is, what it carries, and how it works in practice.
- Regulations: ESPR and adjacent EU legislation, including how obligations arrive over time.
- Standards & Technology: identifiers, data carriers, GS1 Digital Link, resolvers and data exchange.
- Implementation: requirements, data readiness and step by step delivery guidance.
- Governance & Assurance: structured ways to assess scope, evidence and ongoing obligations.
- Industry Guides: sector specific interpretation. Coming soon.
- Templates: reusable checklists and data structures. Coming soon.
- Examples: worked examples of passport data in context. Coming soon.
- FAQs: direct answers to the questions we are asked most.
- Glossary: the canonical definitions of recurring terms and acronyms. Every article links its key terms here on first use.
Recommended Reading Path
If you are new to the topic, read these two in order. Together they cover the foundations that every later article builds on.
- Digital Product Passports (Overview): orientation to the category and the concepts involved.
- What is a Digital Product Passport? : the definition, the legal basis, the data, and the mechanics of access.
From there, follow the category that matches your responsibility: Regulations for legal timing, Standards & Technology for the technical layer, or Implementation for delivery. Keep the Glossary open alongside them for any unfamiliar term.
Our Editorial Principles
- Primary sources first. Articles are grounded in the published legal texts, official standards and the institutions responsible for them, and cite them so you can verify any claim.
- Confirmed law is separated from emerging guidance. Where something is set in a regulation already in force, we say so. Where it depends on a future delegated act, draft standard or pending guidance, that is stated plainly rather than presented as settled.
- Maintained as legislation evolves. Articles are reviewed on a schedule and updated when the underlying law, standards or guidance change. Each article records when it was last reviewed.
- Clear, practical language. Regulatory text is precise but rarely readable. We explain what a requirement means in operational terms, without diluting what it actually says.
About tieback Knowledge
This is a reference library, not a blog. There are no opinion pieces, no launch announcements and no news cycle. Articles are structured, versioned and revisited so that the same page remains correct months after it was written: and so that a page you cited last quarter still tells you when it was last checked.
The aim is educational: to give anyone working on product compliance a dependable place to understand Digital Product Passports and the regulations surrounding them.
