All fields have been completed; the document has been filed and yet the most critical gap may only become apparent when supporting evidence is requested.
- Does the declaration truly correspond to the current packaging?
- Are material data, technical specifications, and supplier documentation clearly linked to it?
- How can you ensure that an outdated DoC is no longer used after changes have been made?
These questions determine whether a completed template becomes a reliable Declaration of Conformity (DoC).
Under the Packaging and Packaging Waste Regulation (PPWR), formal completeness alone is not enough. The information must be clearly defined, up to date, and supported by traceable evidence.
Completeness Means More Than Just Filling in Every Field
The PPWR specifies a clear structure for the EU Declaration of Conformity. This includes, among other things, identification of the declaration and the packaging concerned, manufacturer details, a description of the object of the declaration, and references to applicable legislation and, where relevant, standards or technical specifications. However, a formally complete DoC is not automatically a reliable one.
What matters is the information behind the declaration: Is it clearly defined, up to date, and supported by the relevant technical documentation? This is precisely where gaps frequently arise in practice.
Three Common Weaknesses in Practical Implementation
The first challenge is a clear identification of the packaging. It must be possible to determine exactly which clearly defined group of packaging items is covered by the declaration. Descriptions that are too general can make this identification difficult.
The second challenge concerns the underlying data and supporting evidence. In many companies, material information, technical specifications, and supplier documents are stored across different systems and departments. However, a DoC can only be as reliable as the information on which it is based.
Third, keeping information up to date is essential. Materials change, suppliers are replaced, and packaging designs are modified. Companies therefore need a process to identify when such changes affect the technical documentation and the existing DoC.
Beware of the Template Trap
Using a standardised DoC template can be useful for companies with extensive packaging portfolios. However, it does not replace the need to verify the underlying information.
Problems arise when packaging descriptions or technical references are copied from existing declarations without checking whether they actually apply to the packaging concerned.
The key question should therefore not simply be: “Do we have a DoC for this packaging?”
Instead, it should be:“Can we substantiate the statements made in this DoC with up-to-date, clearly assigned supporting evidence?”
Achieving this requires a clear connection between packaging identification, technical data, supplier documentation, conformity assessment and the resulting declaration.
From Individual DoCs to a Scalable Compliance Process
For companies with large and international packaging portfolios in particular, managing DoCs becomes a matter of processes and data management.
Who is responsible for which information? Where is supporting evidence stored? How are changes identified? And how can companies ensure that the current declaration actually corresponds to the latest packaging version?
This is exactly where 1cc and TechProtect work together. 1cc translates PPWR provisions into clear requirements for conformity assessment, documentation and internal processes. TechProtect ensures that the necessary packaging information and supporting evidence are systematically consolidated, structured and made available for operational use. The result is a transparent, traceable, and scalable packaging compliance process that goes beyond managing individual documents.
The Next Step: From Packaging to Market
However, regulatory responsibility does not end with a complete DoC.
As soon as packaging is made available in different European markets, Extended Producer Responsibility (EPR) becomes a central consideration.
The key question then becomes: “Which obligations arise in which countries, and how can companies efficiently manage them when distributing products internationally?” This is exactly what we will explore in the next article in our series.
How Reliable Is Your DoC Today?
Are your packaging items, technical evidence, and Declarations of Conformity already clearly linked? Or does every compliance review require relevant information to be gathered again from multiple sources?
1cc and TechProtect help transform existing documentation into a robust packaging compliance process – one that is aligned with regulatory requirements, supported by up-to-date evidence, and scalable in day-to-day operations.
We review your existing DoC processes, identify specific gaps in supporting evidence, and ensure that declarations, packaging versions, and technical documentation are consistently and reliably aligned.
