A merchant private-labeling LED string lights from an overseas factory got a polite but firm email from their payment processor's compliance team in February, asking for a copy of the EU Declaration of Conformity and proof of CE marking before they'd continue processing transactions for that SKU. The merchant had a CE logo on the product photo, printed on the box by the factory, but no declaration, no technical file, and no idea they'd become the 'manufacturer' in the eyes of EU law the moment they put their own brand on someone else's product.
What CE Marking Actually Is
CE marking is not a quality stamp and, for most products, it isn't third-party certification either. It's the manufacturer's own declaration that a product meets every applicable requirement under EU harmonised legislation, backed by an EU Declaration of Conformity and a technical file. That harmonised legislation includes, depending on the product, the Low Voltage Directive, the EMC Directive, the Radio Equipment Directive for anything wireless or Bluetooth-enabled, the Toy Safety Directive, the Machinery Regulation, and the Personal Protective Equipment Regulation, among others.
Not every product needs CE marking. Furniture, most textiles and apparel, and plenty of general merchandise fall outside harmonised legislation entirely and never carry the mark. Putting a CE logo on something that doesn't require it, or that hasn't genuinely gone through the process, is itself a compliance problem, not a neutral marketing flourish.
Self-Declaration vs Notified Body Involvement
| Product example | Applicable legislation | Third-party (notified body) involvement |
|---|---|---|
| USB power adapter | Low Voltage Directive, EMC Directive | Usually self-declared by the manufacturer, no notified body required |
| Bluetooth speaker | Radio Equipment Directive | Usually self-declared, notified body only for certain radio categories |
| Children's soft toy | Toy Safety Directive | Depends on standard compliance; some toys need notified-body type-examination |
| Complex machinery, or PPE category III | Machinery Regulation, PPE Regulation | Notified body assessment typically required |
| Furniture, apparel, most homeware | No CE-relevant harmonised legislation | Not applicable, no CE marking |
Who Becomes the Manufacturer, and Why It Matters for You
If you import a product from outside the EU and are the first to place it on the EU market, you take on importer obligations: verify the actual manufacturer completed the correct conformity assessment, keep a copy of the Declaration of Conformity and technical file, or know where to get it within a reasonable time, ensure the CE mark and your name and address as importer appear on the product or packaging, and don't alter the product in a way that could affect compliance.
If you private-label the product, putting your own brand on it, or make any change the original manufacturer didn't assess, EU law generally treats you as the manufacturer, not the importer. That's a materially bigger set of obligations: you need your own EU Declaration of Conformity, your own technical file, and full accountability for the product meeting every applicable directive, not just import-level checks. This is the distinction that caught out the merchant in the opening example — a rebrand isn't a cosmetic change under this framework, it's a legal one.

CE Marking Requirements Checklist
Before sourcing or listing a CE-relevant product
- Identify which harmonised legislation applies to the product category by checking the applicable EU directive or regulation list for that product type
- Ask your supplier or manufacturer for the EU Declaration of Conformity and confirm it names the correct product, model, and applicable directives
- Request the technical file, or written confirmation you can obtain it within a reasonable timeframe if a market surveillance authority asks
- Check whether the category requires notified-body involvement, and if so, confirm the notified body's identification number appears where required
For your product listings and packaging
- Verify the CE mark is correctly proportioned and affixed to the product, packaging, or accompanying documentation per the applicable rules, including minimum height and visual proportions
- Add importer name and address to packaging or documentation if you're the first to place the product on the EU market
- Avoid marketing language like 'CE certified' that implies third-party certification unless a notified body was genuinely involved; 'CE marked' is the accurate term for self-declared conformity
Ongoing
- Keep the Declaration of Conformity and technical file for at least ten years from when the product was placed on the market, or the period your national authority specifies
- Re-check conformity documentation whenever you change suppliers for the same product category, since a new source means a new declaration
- If you private-label or modify a sourced product, treat yourself as the manufacturer and complete a full conformity assessment rather than relying on the original factory's paperwork
Your CE marking action plan
List every product you sell that falls under a CE-relevant category, anything electronic, wireless, a toy, or PPE, and request the Declaration of Conformity for each from your supplier this week; a missing or mismatched declaration is the single most common reason payment processors and marketplaces suspend listings without warning. For the full regulatory picture, our complete EU compliance checklist ties CE marking together with the other obligations covered in this series.
Frequently asked questions
Does every product sold online need CE marking?
No. CE marking only applies to products covered by specific EU harmonised legislation, such as electronics, toys, machinery, and PPE. General merchandise like furniture, textiles, and most homeware falls outside these rules and shouldn't carry the mark at all.
Is CE marking third-party certified, or can the manufacturer self-declare?
For most product categories, CE marking is a manufacturer self-declaration backed by a Declaration of Conformity and technical file. Only specific higher-risk categories, like certain toys, machinery, or PPE, require notified-body involvement.
What happens if I private-label a product I import?
Putting your own brand on a sourced product generally makes you the manufacturer under EU law, not just the importer. You take on full responsibility for conformity assessment, the Declaration of Conformity, and the technical file.
What documents should I request from my supplier before listing a CE-relevant product?
Ask for the EU Declaration of Conformity naming the correct product and applicable directives, and confirmation you can access the technical file within a reasonable time if an authority requests it.
Can I say a product is 'CE certified' in my marketing?
Avoid that wording unless a notified body genuinely certified the product. CE marking for most goods is a self-declaration, so 'CE marked' is the accurate term; 'CE certified' overstates third-party involvement.
How long do I need to keep CE marking documentation?
Keep the Declaration of Conformity and technical file for at least ten years from when the product was placed on the market, or longer if your national market surveillance authority specifies otherwise.
