Verifying a Chinese Lighting Supplier's CE Certificate: A Specifier's Guide to the EU NANDO Database

Introduction

Every luminaire package that arrives on a European hospitality project carries a folder of paperwork. Among the test reports, warranty statements, and product datasheets sits a document stamped “CE Certificate” — often issued by a laboratory your client has never heard of, referencing a standard number nobody on the design team has read, and covering a model name that does not quite match what was delivered.

For architects, interior designers, and hotel procurement teams, this is where a specification quietly becomes a liability. A hotel lobby is not a one-off purchase; it is a ten-year maintenance commitment, a warranty negotiation, and in many jurisdictions a compliance obligation that falls partly on the party who specified the product.

The good news is that the European Union maintains a free, public, and authoritative tool that lets you pressure-test a supplier’s certification claims in minutes. It is called NANDO — the New Approach Notified and Designated Organisations database. This guide explains how to use it, what it can and cannot prove, and where most supplier documentation falls apart under scrutiny.

What NANDO Is — and What It Is Not

NANDO is the European Commission’s official register of conformity assessment bodies that have been formally notified or designated by EU member states and other participating countries to carry out tasks under specific pieces of Union legislation.

It is not a certificate database. This distinction matters enormously, because many buyers assume that finding a body’s name in NANDO means the certificate it issued is therefore valid. It does not. NANDO tells you three things:

1. Whether the organisation exists and is a legitimate legal entity.
2. Whether it holds a notified body identification number, typically a four-digit code.
3. Which specific Union legislation it is designated to act under, and whether that designation is currently active, restricted, or withdrawn.

What NANDO does not tell you is whether a particular certificate is genuine, whether the product tested matches the product shipped, or whether the correct harmonised standards were applied. Those checks happen elsewhere.

Reading a NANDO Entry Step by Step

Start at the Commission’s NANDO portal and select the relevant Union legislation — for lighting, most commonly the Low Voltage Directive (2014/35/EU), the Electromagnetic Compatibility Directive (2014/30/EU), the Radio Equipment Directive (2014/53/EU) for wireless controls, or the Ecodesign framework (2009/125/EC).

Then search by the notified body’s four-digit number or by its legal name. A credible entry will show a designation date, a scope description, and current status. Pay particular attention to scope: a body designated to assess, say, machinery or personal protective equipment has no standing to issue a certification opinion on a luminaire. Suppliers occasionally present such documents because the letterhead looks authoritative to a non-specialist buyer.

The Critical Nuance Most Buyers Miss

Here is the fact that reframes the entire conversation: for most architectural luminaires, a notified body is not legally required at all.

The Low Voltage Directive and the Electromagnetic Compatibility Directive are both based on manufacturer self-declaration. The manufacturer — or the importer placing the product on the EU market — signs an EU Declaration of Conformity, compiles a technical file, and affixes the CE marking. No third party signs off. The same is true for the RoHS Directive (2011/65/EU) and for the Ecodesign requirements for light sources and separate control gear under Regulation (EU) 2019/2020.

This means a document titled “CE Certificate” issued by an external laboratory is, in most cases, a commercial artefact rather than a legal one. It may be genuinely useful as evidence of testing. It is not what makes the product CE-compliant.

When a Notified Body Is Genuinely Involved

There are situations where third-party involvement is real and worth verifying:

• Radio Equipment Directive (2014/53/EU): if a wireless lighting control system does not apply harmonised standards in full, a notified body must be engaged and its number must appear on the declaration.
• Voluntary certification schemes: some manufacturers choose notified body testing for market positioning, particularly where a specifier demands it.
• Specialist legislation: certain components, such as some emergency lighting or intrinsically safe equipment for hazardous environments, sit under frameworks with different assessment routes.

In these cases, the notified body’s identification number should appear on the EU Declaration of Conformity itself. If the supplier cannot point to that number, the claim of notified body certification should be treated as unverified.

“A CE mark is not a badge a laboratory awards you. It is a legal declaration the manufacturer makes, and it is only as credible as the technical file behind it.”

A Verification Workflow for Architects and Specifiers

Use the following sequence when qualifying a new supplier or auditing an existing one. It takes under an hour and consistently surfaces problems early, before they become site issues.

Step 1: Request the EU Declaration of Conformity, Not the Certificate

The DoC is the legally operative document. It must identify the manufacturer, the product, the applicable Union legislation, the harmonised standards applied, and, where relevant, the notified body. If a supplier can only produce a “certificate” and not a DoC, the compliance chain is incomplete.

Step 2: Identify the Legislation the Product Actually Falls Under

A dimmable LED downlight with a wireless driver may fall under the Low Voltage Directive, the EMC Directive, and the Radio Equipment Directive simultaneously. Each one requires its own conformity assessment reasoning. Suppliers who list a single directive for a multi-function product are usually working from an old template.

Step 3: Determine Whether a Notified Body Should Appear at All

If the supplier claims notified body certification, check whether the relevant directive requires it. A notified body number on a Low Voltage Directive declaration is, at minimum, unusual — and worth questioning.

Step 4: Search NANDO for the Body and Its Scope

Confirm the body is listed, confirm the designation is active on the date the certificate was issued, and confirm the scope covers the relevant legislation. A body whose designation was withdrawn three years ago cannot have validly issued a certificate last month.

Step 5: Contact the Notified Body Directly

This is the only reliable way to confirm that a specific certificate number corresponds to a specific product, model, and client. Notified bodies maintain their own certificate registers and will normally validate a document on request. Ask the supplier to authorise the enquiry.

Step 6: Check EPREL for Light Sources

For LED lamps, modules, and separate control gear, the Ecodesign and Energy Labelling Regulation requires registration in the European Product Registry for Energy Labelling (EPREL) before the product is placed on the market. A supplier unable to provide an EPREL registration is a supplier with an incomplete compliance file — this is one of the fastest, most objective checks available to a specifier.

Red Flags That Warrant Escalation

• The certificate is issued by an organisation absent from NANDO, often with a name closely resembling a well-known European body.
• The document is titled “Certificate of Compliance” or “Test Report” but is presented verbally as a CE certificate.
• The model designation on the certificate does not match the specification sheet or the delivered goods.
• Harmonised standards cited are withdrawn or superseded versions.
• The certificate covers a product family with no defined boundary — “all LED lighting products” is not a meaningful scope.
• No EU-based economic operator or authorised representative is identified, despite the requirements of Regulation (EU) 2019/1020.
• The supplier cannot produce a technical file or declines to allow direct contact with the issuing body.

What This Means for Your Project

Compliance failures rarely announce themselves at the specification stage. They surface at customs clearance, at a market surveillance inspection, during an insurance claim after a fire incident, or when a hotel operator tries to reorder a product that has quietly been withdrawn from the market. In each scenario the cost falls disproportionately on the party who specified the product, because that party holds the professional responsibility for the selection.

Verifying certification is not administrative pedantry. It is the same discipline as verifying load calculations or fire ratings — an exercise in protecting the client, the project, and your own professional position.

Conclusion

The NANDO database will not, on its own, tell you whether a Chinese lighting supplier’s product is compliant. What it will do is separate legitimate conformity assessment bodies from organisations that merely print impressive documents, and it will tell you whether third-party involvement was ever required in the first place. Combined with a properly signed EU Declaration of Conformity, a coherent technical file, and EPREL registration where applicable, it forms the backbone of a defensible specification.
