EU CE Marking Declaration of Conformity Checklist: A Practical Guide
A concise guide to building and reviewing an EU declaration of conformity for CE-marked products, with a practical checklist and retention rules.
An EU declaration of conformity is the manufacturer’s formal statement that a product meets the applicable EU harmonisation legislation. It is not a certificate, and it does not transfer responsibility to a notified body. When a product falls under one or more CE marking directives or regulations, the declaration must accompany the product, be signed, and be available to market surveillance authorities. A reliable EU CE marking declaration of conformity checklist helps teams avoid omissions before the document is signed and shipped.
What the EU Declaration of Conformity Actually Is
The declaration is a legal document required by sector-specific EU product rules, such as the Machinery Regulation, Low Voltage Directive, EMC Directive, Radio Equipment Directive, or Medical Devices Regulation. Under Regulation (EU) 2019/1020, market surveillance authorities can demand it as part of compliance evidence. The declaration summarises which rules apply, which conformity assessment procedure was followed, and which standards or technical specifications were used. It must be written in the official language(s) required by the Member State where the product is made available. It must also be kept for the retention period set by the applicable legislation, often 10 years after the product is placed on the EU market.
Core Elements of an EU CE marking declaration of conformity checklist
A workable checklist mirrors the mandatory content in the applicable EU legislation. While wording varies by directive or regulation, most declarations need the same core data.
Manufacturer and Authorised Representative Details
List the manufacturer’s full legal name and registered address. If an authorised representative is appointed in the EU, include that entity’s name and address. Do not use a trading name unless it is the legal entity. If the manufacturer is outside the EU, confirm who will hold the technical documentation and respond to authorities.
Product Identification and Applicable Legislation
Identify the product clearly: model, type, batch, serial number, or other unique reference. State every EU directive, regulation, or decision that applies. Avoid vague phrases such as “EU directives” without listing the exact legal instruments. If the product has multiple functions, check whether more than one CE marking regime applies.
Conformity Assessment and Standards
Describe the conformity assessment procedure used. For many products, this is internal production control under a module such as Module A. For higher-risk products, a notified body may be involved. List the harmonised standards, common specifications, or other technical solutions used. Use canonical references: ISO 9001, ISO 14001, ISO 45001, ASTM D4169, ASTM A36. If a standard is not harmonised, explain how it supports conformity.
Signatory and Date
The declaration must be signed by the manufacturer or an authorised representative. Include the signatory’s name, function, place, and date. A digital signature may be acceptable if the applicable legislation and Member State practice allow it. Keep the signed master version under document control.
Step-by-Step Completion Workflow
- Identify the product’s EU legislation and CE marking scope.
- Select the conformity assessment module using the Conformity Assessment Module Selection Guide For EU CE Marki.
- Build or update the technical file with the EU CE Marking Technical File: A Practical Guide.
- Compile test reports, risk assessments, drawings, bills of materials, and instructions.
- Draft the EU declaration of conformity using the applicable annex or model wording.
- Check language requirements for each target Member State.
- Sign, date, and release the declaration with the product.
- Retain the declaration and technical documentation for the required period.
A second reviewer should compare the draft against the EU CE marking declaration of conformity checklist. This catches missing legislation, outdated standards, and address changes.
Common Mistakes and Market Surveillance Risks
Missing or incorrect legal references are frequent. Another common error is listing a standard without the correct edition or amendment. Products sometimes carry the CE marking before the declaration is signed, which weakens the compliance trail. If the manufacturer is outside the EU, the absence of an authorised representative can create enforcement problems. Authorities may request the declaration, technical file, and test evidence. If the documents are incomplete, they can order corrective action, withdrawal, or recall. GDPR obligations may also apply if the product processes personal data; see GDPR Data Processing Agreement Clauses: A Practical Guide for related contract terms.
Documentation, Retention, and Language Rules
The EU declaration of conformity is part of the technical documentation. Keep it with the technical file, test reports, risk analysis, and quality records. The retention period depends on the applicable legislation, but 10 years after the last product is placed on the market is a common benchmark. Translate the declaration into the language(s) required by the Member State. If the product is sold online, the declaration must still be available. Do not rely on a single English version for all EU markets. For products that also involve personal data, separate GDPR records may be needed.
How to Use the Checklist with Other Compliance Records
Use the EU CE marking declaration of conformity checklist as a gate before product release. Link it to the technical file index, the conformity assessment module decision, and the label review. If the product uses materials or components tested under ASTM methods, keep those reports in the technical file. The declaration should reference the final product, not just a component. When legislation changes, review the declaration and update it if the applicable requirements, standards, or authorised representative details change. A controlled template with version history reduces the risk of shipping an obsolete declaration.
The declaration is short, but it carries legal weight. A disciplined checklist keeps the document accurate, traceable, and ready for market surveillance. Start with the applicable EU legislation, verify every mandatory field, and retain the evidence that supports each statement.

Frequently asked questions
What is an EU declaration of conformity?
It is a signed legal statement by the manufacturer or authorised representative that the product meets the applicable EU harmonisation legislation. It supports the CE marking and must be available to authorities.
Is the EU declaration of conformity the same as a CE certificate?
No. A CE certificate is issued by a notified body for certain conformity assessment modules. The declaration is the manufacturer's own statement, though it may reference a notified body certificate where applicable.
What must be included in the declaration?
Manufacturer details, product identification, applicable EU legislation, conformity assessment procedure, standards or specifications, signatory details, place, and date. The exact mandatory fields depend on the applicable directive or regulation.
How long must the declaration be kept?
The retention period is set by the applicable EU legislation. A common period is 10 years after the product is placed on the market, but always check the specific rule for the product.
Does the declaration need to be translated?
Yes, it must be in the official language(s) required by the Member State where the product is made available. A single English version is usually not enough for all EU markets.
Can a non-EU manufacturer sign the declaration?
Yes, the manufacturer can sign. If the manufacturer is outside the EU, an authorised representative may be required by the applicable legislation to hold documentation and cooperate with authorities.
