Sample Declaration of Conformity — annotated walkthrough with template

A signed Declaration of Conformity is the legal artefact that lets a CE-marked product enter the EU market. Most first-time manufacturers know they need one but have never seen a complete annotated example. This article walks through a full sample DoC for a connected industrial sensor — covering CRA, RED, LVD, EMC, and RoHS — with the legal requirement cited element by element.

That is the entire document. One A4 page is sufficient for a CE-marked connected product subject to five directives plus a small handful of harmonised standards.

Element-by-element annotation

Element 1 — Manufacturer

"The name and address of the manufacturer." — CRA Annex V item 4(a), RED Annex VI item 1

The legal entity placing the product on the market. Use the registered legal name as it appears in the commercial register, not a trading name or brand name. Postal address must be a real address; PO boxes alone are insufficient for most directives.

Slovak, Polish, Czech, German manufacturers also list company registration numbers (IČO/REGON/IČ/HRB) — not strictly required by CRA Annex V but standard practice and useful for authorities to verify the legal entity.

For non-EU manufacturers, this element still names the manufacturer. Element 2 adds the EC REP.

Element 2 — EU Authorised Representative

"Where applicable, the name and address of the authorised representative." — CRA Annex V item 4(b)

If the manufacturer is established in the EU/EEA, this element is marked "not applicable" or simply omitted with a note.

For a non-EU manufacturer, the EC REP's full legal name and EU/EEA address appear here. Example:

2. EU Authorised Representative
   CE REP Services s.r.o.
   Karpatské námestie 7770/10A
   831 06 Bratislava, Slovakia
   Authorised under written mandate dated 15 April 2026

Element 3 — Product identification

"The product type and any additional information enabling traceability of the products with digital elements." — CRA Annex V item 5

What the auditor needs to match the DoC to a physical unit:

• Product name — the marketing name
• Type / model designation — the technical designation that appears on the product label
• Serial number range — the range of units covered by this DoC
• Hardware revision — when applicable (Rev C, board v3, etc.)
• Firmware version — important for products under CRA where software conformity matters
• Photograph — colour photograph attached as an annex; CAD render is acceptable for non-cosmetic products

If the DoC covers a product family with multiple variants, list all variants explicitly. Generic "all our smart sensors" wording is non-compliant.

Element 4 — Statement of sole responsibility

"This declaration of conformity is issued under the sole responsibility of the manufacturer." — CRA Annex V item 1, verbatim wording

This is a literal statement required word for word in many directives. Rephrasing it ("we hereby declare that we take responsibility for…") is risky — auditors look for the exact phrasing.

The statement is what makes the DoC a legally binding act. The manufacturer takes personal responsibility — not the consultant who drafted it, not the test lab that produced the reports, not the distributor that sells it.

Element 5 — List of applicable directives and regulations

"References to the relevant Union harmonisation legislation." — CRA Annex V item 6

Cite each directive or regulation by full formal reference including:

• Regulation or directive number — Regulation (EU) 2024/2847, Directive 2014/53/EU
• Date of adoption
• Brief subject (matches the Official Journal title)

Short names ("the CRA", "RED") are acceptable in addition but not in place of the formal reference. The formal reference is what auditors verify against EUR-Lex.

Do not cite repealed directives. The Low Voltage Directive in force is 2014/35/EU, not the long-superseded 2006/95/EC. Cite the version currently in force on the date of signing.

Element 6 — List of harmonised standards applied

"References to the relevant harmonised standards used or references to the other technical specifications in relation to which conformity is declared." — CRA Annex V item 6

Cite each standard by standard number + year + amendments:

• EN 18031-1:2024 — base version 2024
• EN 62368-1:2014+A11:2017 — base 2014 with amendment A11 from 2017
• EN 55032:2015+A11:2020 — base 2015 with amendment A11 from 2020

The version date matters because standards are amended and earlier versions are withdrawn. The Official Journal lists the currently-cited version per directive; check it on the date of signing.

Where a standard is only partly applied, add a justification or annex describing what alternative measure replaces the part not applied. Pure partial application without justification breaks the presumption of conformity.

Element 7 — Notified Body details

"Where applicable, the name and identification number of the notified body, a description of the conformity assessment procedure performed and identification of the EU-type examination certificate issued." — CRA Annex V item 7

For Module A self-assessment, this element states "not applicable" with a reference to the article permitting self-assessment.

For products requiring a Notified Body:

7. Notified Body
   Name:                 TÜV SÜD Product Service GmbH
   Address:              Ridlerstraße 65, 80339 München, Germany
   Identification number: 0123
   Conformity assessment: Module B+C per RED Article 17(2)(c)
   Certificate reference: TUVPS-EU-12345-2026
   Date of certificate:   12 March 2026

The four-digit NB number appears here and on the product itself beside the CE mark.

Element 8 — Additional information

"Additional information." — CRA Annex V item 8, optional

Use for clarifications that do not fit elsewhere — typically pointers to specific delegated regulations under a directive (Commission Delegated Regulation 2022/30 under RED), or notes about the support period under CRA Article 13(8).

Element 9 — Place and date of issue, signatory

"Place and date of issue, name and position of the signatory." — RED Annex VI item 8

• Place of issue — city and country (matches the manufacturer address most commonly)
• Date of issue — the date the DoC was signed; this is distinct from the date the product was placed on the market
• Name — full name of the individual signing
• Function — explicit role (Managing Director, Quality Manager, Compliance Officer, CEO — not just a name)
• Signature — handwritten ink signature, or qualified electronic signature under eIDAS Regulation 910/2014. Both have the same legal effect.

What to adapt for your product

The structure of the sample DoC applies to almost any CE-marked product. Variables to replace:

• Manufacturer identification — your company
• EC REP if you are non-EU
• Product identification — your product details
• Applicable directives — the directives that apply based on your product type
• Harmonised standards — the standards you applied in your conformity assessment
• Notified Body details — if applicable to your conformity assessment route
• Signatory — the authorised person at your organisation

Constants across all DoCs:

• Element 4 — the statement of sole responsibility wording
• Element 5 — the obligation to list every applicable directive in a single document
• Element 8 — the additional information element exists but is often unused
• Element 9 — place, date, name, function are all required

Common formatting mistakes

From audit experience:

• DoC issued in a language not used in the target market. The DoC must be drawn up in an official EU language, and a translation must accompany the product on first delivery in the language of the market of sale. English-only is insufficient for sales in Germany.
• Missing signature. A typed name is not a signature. Either handwritten ink or a qualified electronic signature under eIDAS is required.
• Element 4 paraphrased. "We declare that…" is not the same as the literal "issued under the sole responsibility of the manufacturer". Audit risk.
• Mixed-version standard citations. "EN 55032" without a year is ambiguous. Cite the year and any amendment.
• Product photograph not attached. Element 3 traceability requires a photograph for non-trivial products. A purely textual product description rarely satisfies.

How Cenitia generates DoCs

Cenitia's DoC generator produces this exact structure from your product description, the directives Cenitia's auto-mapper identifies as applicable, and the harmonised standards currently cited in the Official Journal for each. Every claim cites back to the relevant EUR-Lex article and standard. The signed PDF is cryptographically signed and carries a public QR code an auditor can scan to verify authenticity.

Frequently asked questions

Can I use this template directly for my own product?

The structure is reusable but the content is product-specific. The manufacturer identification, product identification, list of applicable directives, list of harmonised standards, and signatory information all have to be replaced with values accurate for your product. Submitting a copy-pasted DoC with another company's details is a serious legal exposure.

Does the DoC need to be on company letterhead?

There is no formal requirement for letterhead, but it is standard practice. The legal requirements set in CRA Annex V, RED Annex VI, and parallel annexes do not prescribe formatting. What matters is that the document contains the nine required elements and is identifiable as issued by the manufacturer named in element 1.

Can the DoC fit on one page?

Yes, in almost every case. For a product subject to four to six directives plus a handful of harmonised standards, the DoC fits comfortably on a single A4 page. Multi-page DoCs typically indicate either an unusually broad product family or unnecessary verbosity. The legal requirements set the floor, not a target.

Where do I list the EC REP if my company is outside the EU?

Element 2 of the DoC names the EU Authorised Representative — their full legal name and contact address. The EC REP appears in addition to the manufacturer in element 1, not in place of it. The manufacturer remains the legal entity that signs and takes responsibility; the EC REP is the legal point of contact within the EU.

Does each directive need its own DoC?

No. One Declaration of Conformity covers every applicable directive for a single product. Listing CRA, RED, LVD, EMC, and RoHS on one document is the correct format. Issuing five separate DoCs is incorrect and triggers questions during market surveillance inspection.

What happens if I list a harmonised standard version that has been withdrawn?

The presumption of conformity from a withdrawn harmonised standard no longer applies after the withdrawal date set in the Official Journal. The DoC remains valid as a document, but the technical claim of conformity loses its safe harbour and the manufacturer must demonstrate conformity through another means. In practice, cite the currently-listed version and update the DoC and Technical File together.
