Store your Declaration of Conformity in a controlled, retrievable compliance file where you can produce the exact version for the exact product on request, and it does not need to physically accompany the product in the box. In practice, that means keeping a digital master copy with version control, plus a backup, and ensuring it is accessible for EU authorities when requested.

This applies to products that require a DoC under their applicable EU harmonization legislation, and it sits alongside your CE marking documentation and broader EU compliance records for technical documentation. Requirements can vary by product law, but the core expectation is fast availability during a market surveillance request.

The questions below break down EU Declaration of Conformity storage, whether a paper copy must ship with the product, and DoC retention requirements.

Where should you store the EU Declaration of Conformity (DoC)?

The EU Declaration of Conformity should be stored in your technical documentation file in a way that is secure, version controlled, and quickly retrievable for a market surveillance request. For EU Declaration of Conformity storage, a digital system is usually best, as long as you can show the correct DoC for the exact product, model, and production period.

Good storage is less about a specific folder name and more about traceability. Authorities typically expect you to identify the product and link it to the correct compliance evidence without delay. That means your DoC should be tied to the same identifiers used on the product and packaging, such as model number, SKU, batch, or serial range where relevant.

  • Keep a signed master DoC in a controlled location with edit restrictions.
  • Use version control so you can prove what changed and when, especially after design updates or standards updates.
  • Link the DoC to the technical file that supports it, including test reports, risk assessment, and applicable standards list.
  • Maintain a retrieval index by product family and model so you can respond quickly to a market surveillance request for the DoC.
  • Back up the file in a separate secure location to avoid loss.

If you sell through online marketplaces, also keep a readily shareable copy for platform compliance checks, but do not confuse a platform upload with your official controlled record.

Does the Declaration of Conformity have to physically accompany the product?

No, the Declaration of Conformity generally does not have to physically accompany the product as a paper document in the box. For most CE marking documentation regimes, the legal requirement is that the DoC exists, is correct, and can be made available to authorities upon request, not that every unit ships with a printed copy.

That said, some product rules require specific information to accompany the product, such as safety instructions, warnings, and certain compliance markings. Those obligations are separate from whether the DoC itself must be included. A practical approach is to ensure the end user receives all required safety information, while you keep the DoC in your compliance system for rapid production if asked.

Common, low-risk ways to support transparency without creating document control problems include providing a web link or QR code to a publicly viewable DoC copy, as long as your controlled master remains unchanged and you can demonstrate authenticity and version alignment.

  • Do not ship outdated DoCs if you choose to include a copy or link.
  • Match languages for any user-facing safety information that must accompany the product.
  • Keep the DoC separate from marketing claims so it stays a formal legal declaration.

How long do you need to keep the Declaration of Conformity and related technical documentation?

DoC retention requirements depend on the specific EU legislation that applies to your product, but a common baseline across many CE marking frameworks is keeping the Declaration of Conformity and the technical documentation for ten years after the last unit is placed on the market. You should confirm the exact retention period in the product’s governing act.

Retention is not only about keeping a PDF. You need to preserve the full EU compliance package for technical documentation that supports the declaration, in a form that remains readable and complete over time. That matters when authorities investigate complaints, verify conformity, or review safety measures after an accident.

  • Keep the final DoC plus any earlier versions that correspond to older production runs still in circulation.
  • Retain supporting evidence such as test reports, design drawings, BOM changes, and risk assessments.
  • Preserve standards references used at the time of declaration, including the edition year where relevant.
  • Maintain change logs for product updates that could affect conformity.

If you operate under the Market Surveillance Regulation (EU) 2019/1020 (MSR), be ready to provide documentation to authorities and to coordinate responsibilities correctly. Under the MSR, the responsible person role is carried out by an economic operator, and that economic operator must, among other duties, inform the manufacturer when it has reason to believe a product presents a risk, in line with Article 4.

Separately, the General Product Safety Regulation (EU) 2023/988 (GPSR) sets broad consumer product safety expectations, including strong traceability and documentation discipline for products within scope. Even when a DoC is not part of GPSR obligations, good documentation retention supports faster, cleaner responses to authority questions.
