PPWR Declaration of Conformity: Requirements for Packaging Manufacturers 2026

From 12 August 2026, every packaging item placed on the EU market under Regulation (EU) 2025/40 needs an EU Declaration of Conformity signed by the manufacturer. The document is short, often a single page, but it sits on top of a technical file that can run to dozens of pages per SKU. Get the structure wrong and the declaration is legally invalid, the packaging cannot be marketed, and the manufacturer carries the liability. This guide breaks down what goes into the DoC, what backs it up in the technical file, and how to scale the workflow across thousands of references.
