What does Traceability mean?
Traceability is the ability to trace products, evidence and events across supply chains.
Traceability connects suppliers, materials, production steps, batches, serial numbers, documents, checks and events. It shows which data source supports a product value, when it changed and which actor was responsible. Without that connection, product passport data remains static and is hard to evidence in audits, recalls or market surveillance.
Why does it matter for DPP and compliance?
ESPR names traceability as an objective of the Digital Product Passport. A DPP can support it when product identifiers, data carriers, data origin, versions, access levels and evidence are connected consistently. But a DPP does not replace a full supply-chain traceability system; concrete data fields and levels come through delegated acts.
What should teams prepare?
Teams should not treat traceability as a separate project next to DPP. Product, model, batch or serial identifiers, supplier structure, material hierarchy, audit trail, evidence documents, GS1 Digital Link or resolver strategy, role permissions and change processes need to converge in one data model.
