The EU Ecodesign for Sustainable Products Regulation (ESPR) requires Digital Product Passports (DPPs) for a growing range of product categories. A DPP is a structured data record containing information about a product's materials, components, repairability, recyclability, and environmental footprint — accessible via a QR code or RFID tag on the product or packaging. This guide covers the DPP data requirements, QR code and data carrier standards, the ESPR product category rollout timeline, and how to implement a DPP programme that satisfies both EU customs and product compliance requirements.
