CE marking is mandatory for construction products sold in the European Union, including natural and engineered stone surfaces. Understanding CE marking requirements, applicable EN standards, and compliance verification helps importers, distributors, and specifiers meet European regulatory obligations.

What Is CE Marking?

CE marking is a conformity mark indicating that a product complies with EU health, safety, and environmental protection standards. For construction products, CE marking is required under the Construction Products Regulation (EU) No 305/2011.

CE marking allows products to circulate freely within the European Economic Area (EEA), which includes all EU member states plus Iceland, Liechtenstein, and Norway.

CE Marking for Construction Products

The Construction Products Regulation (CPR) establishes:

• Harmonized rules: For marketing construction products

• Declaration of Performance (DoP): Manufacturer's declaration of product properties

• CE marking requirements: Compliance verification and marking

• Assessment and verification systems: Levels of third-party involvement

For stone products, CE marking involves: 1. Determining applicable harmonized standards 2. Conducting required testing 3. Preparing Declaration of Performance 4. Affixing CE marking 5. Maintaining technical documentation

Declaration of Performance (DoP)

The Declaration of Performance is a key CE marking document:

Required Information

• Product type and identification

• Intended use

• Manufacturer name and address

• Authorized representative (if applicable)

• System of assessment and verification

• Harmonized standard reference

• Declared performance characteristics

• Signature of responsible person

Example DoP Structure

``` DECLARATION OF PERFORMANCE No. [Unique identification number]

1. Product type: [Product identification] 2. Type, batch, or serial number: [Traceability information] 3. Intended use: [Application description] 4. Manufacturer: [Name and address] 5. Authorized representative: [If applicable] 6. System of assessment: [AVCP system] 7. Harmonized standard: [EN reference] 8. Declared performance:

• Characteristic | Performance | Standard

• [Various properties and test results]

9. Signature: [Authorized person]

This declaration is issued under the sole responsibility of the manufacturer. ```

Assessment and Verification Systems

CE marking for construction products involves different assessment levels:

System 1

• Initial type testing by manufacturer

• Continuous surveillance by notified body

• Factory production control audit by notified body

• Highest level of third-party involvement

System 2+

• Initial type testing by manufacturer

• Factory production control certification by notified body

• Moderate third-party involvement

System 3

• Initial type testing by notified laboratory

• Manufacturer's factory production control

• Lower third-party involvement

System 4

• Manufacturer's self-declaration

• Manufacturer's factory production control

• Minimal third-party involvement

The applicable system depends on the product and intended use.

Notified Bodies

Notified bodies are organizations designated by EU member states to assess construction product compliance:

Finding Notified Bodies

• [European Commission NANDO database](https://ec.europa.eu/growth/tools-databases/nando/) lists all notified bodies

• Each body has designated scope of activities

• Accreditation by national accreditation bodies

Role of Notified Bodies

• Conduct initial type testing

• Audit factory production control

• Issue certificates of conformity

• Maintain ongoing surveillance (depending on system)

CE Marking Documentation

For CE marked stone products, the following documentation should be available:

Required Documents

1. Declaration of Performance (DoP): Manufacturer's declaration 2. Test reports: From accredited laboratories 3. Certificate of Conformity: If applicable based on assessment system 4. Technical documentation: Supporting manufacturer documentation 5. Product marking: Physical CE mark on product or packaging

Where to Find Documentation

• Manufacturer's website

• Product packaging

• Technical data sheets

• Available on request from supplier

Common CE Marking Mistakes

Incomplete DoP

• Missing required performance characteristics

• Incomplete manufacturer identification

• Outdated standard references

Incorrect Marking

• CE mark with incorrect dimensions (minimum 5mm height)

• CE mark not visible on packaging

• Missing accompanying documentation

Outdated Compliance

• Standards revised but DoP not updated

• Original testing no longer valid

• Production changes without re-assessment

Unverified Claims

• CE mark without actual testing

• Self-declaration for products requiring third-party assessment

• Use of non-accredited laboratories

Verifying CE Marking Compliance

Buyers should verify:

Documentation Review

• Current DoP available

• Test reports from accredited laboratories

• CE certificate (if applicable)

• Technical documentation

Marking Verification

• CE mark properly affixed

• Marking dimensions comply with requirements

• Accompanying information present

Manufacturer Verification

• Manufacturer identified and traceable

• EU authorized representative (for non-EU manufacturers)

• Production location identified

CPR and Brexit Considerations

Following Brexit, the UK has its own construction product regulations:

UKCA Marking

• UKCA (UK Conformity Assessed) marking is required for products sold in Great Britain

• Separate from CE marking

• Similar requirements but UK-specific

CE Marking Acceptance

• CE marking accepted in Great Britain until 2030 for most products

• Northern Ireland continues to accept CE marking under specific arrangements

Dual Marking

• Products sold in both EU and UK may need both CE and UKCA marking

• Documentation requirements for each market

EN Standards Comparison to ASTM

EN standards and ASTM standards cover similar properties but with different methods:

Products can be tested to both EN and ASTM standards, with reports showing compliance for both markets.

REACH and Chemical Safety

In addition to CE marking, stone products must comply with:

REACH (Registration, Evaluation, Authorisation, Restriction of Chemicals)

• SVHC declaration: Substances of Very High Concern disclosure

• Chemical safety: Restrictions on harmful substances

• Communication requirements: Information flow in supply chain

Applicable for Stone Products

• Resin components in engineered stone

• Surface treatments and sealers

• Adhesives used in installation

CE Marking for Specific Applications

Flooring Applications

• Slip resistance testing (EN 14231)

• Wear resistance (EN 14617-4)

• Reaction to fire classification

Wall Cladding

• Mechanical resistance

• Reaction to fire

• Durability

Countertop Applications

• Surface characteristics

• Stain resistance

• Impact resistance

• Thermal shock resistance

Frequently Asked Questions

Is CE marking required for all stone products in the EU? CE marking is required for construction products covered by harmonized standards, which includes most stone surfaces used in construction applications.

How long is CE marking valid? CE marking is valid as long as the product, manufacturing process, and harmonized standards remain unchanged.

Can non-EU manufacturers affix CE marking? Yes, but they must have an EU authorized representative and comply with all CE marking requirements.

What happens if a product lacks proper CE marking? Products without proper CE marking cannot be legally sold in the EU and may be subject to enforcement action by market surveillance authorities.

Is CE marking accepted in the UK? CE marking is accepted in the UK until 2030, after which UKCA marking will be required.

How does CE marking relate to other certifications? CE marking addresses EU regulatory requirements. Other certifications (NSF, GREENGUARD) address different markets and concerns, and may be required in addition to CE marking.
