CE Certification Steps: Complete Step-by-Step Process from Start to CE Mark

Getting CE certification seems overwhelming when you first start — there are directives, harmonized standards, conformity assessment modules, and a mountain of paperwork. I’ve broken it down into 5 actionable steps that any manufacturer can follow. This process takes 2-12 months depending on your product’s complexity and risk level. Let me walk you through each stage with real timelines and practical tips. For a complete overview of the CE certification process, see my CE certification guide.

Step 1: Identify Applicable EU Directives

Start by determining which EU directives apply to your product. Search the EUR-Lex database for directives covering your product category. Most products fall under 2-3 directives simultaneously. For example, a smart thermostat needs EMC Directive (2014/30/EU), Low Voltage Directive (2014/35/EU), and Radio Equipment Directive (2014/53/EU if it has wireless). Create a directive matrix listing each directive, its essential requirements, and the harmonized standards you’ll use. What is CE marking? covers directive identification in detail.

Step 2: Determine the Conformity Assessment Module

Each directive specifies conformity assessment modules (A-H). Module A = internal production control (self-declaration). Module B = EC type-examination (Notified Body required). Higher modules add more rigorous assessment. Check your directive’s Annex to find applicable modules. For most electronics and simple machinery, Module A suffices. Medical devices and PPE need Modules B+C or higher. My guide to choosing a Notified Body helps if you need third-party assessment.

Step 3: Prepare the Technical Documentation

This is the most time-consuming step (60% of total effort). Required: product description, design drawings, risk assessment, list of harmonized standards applied, test reports, Declaration of Conformity, and a copy of the CE marking. The Technical File must be kept for 10 years after the last product is manufactured. I recommend organizing it in a digital folder structure with version control. My CE technical documentation guide has a complete template.

Step 4: Issue the Declaration of Conformity

The DoC is a legal document where you declare your product meets all applicable requirements. It must include: manufacturer name and address, product identification, list of directives and standards, Notified Body details (if applicable), signature of authorized representative, and date. The DoC must be kept with the Technical File and made available to market surveillance authorities on request.

Step 5: Affix the CE Marking

The CE mark must be at least 5mm high, visible, legible, and indelible. If you used a Notified Body, include their identification number next to the CE mark. Place it on the product, packaging, and accompanying documents. That’s it — your product is ready for the European market. But remember: CE compliance is ongoing. When standards update or you modify your product, revisit the process.

One additional consideration: many manufacturers find that working with a certification consultant during the documentation phase pays for itself through fewer re-test cycles. Consultants familiar with your product category can identify gaps before submission, saving 2-4 weeks of rework. Budget 00-200/hour for consulting support if your internal team lacks certification experience.
