CE Marking Certificate
CE Marking Certificate (also known as CE Marcatura) is a mandatory marking that confirms the product’s compliance with European Union legislation, specifically with basic requirements for safety, health protection, and environmental protection. The abbreviation “CE” comes from the French “Conformité Européenne”, meaning “European conformity”. By affixing this mark, the manufacturer declares that the product meets all technical and legislative requirements set by applicable European directives and regulations. CE is not a mark of quality, nor does it indicate the country of origin, but rather enables the free movement of products on the EEA internal market.
Key points:
- CE means “Conformité Européenne” (European conformity)
- Applies to products sold in the European Economic Area (EEA)
- Is a “business passport” for products on the European market
- Is not a quality certificate, but compliance with legislative requirements
Basic Legislation and Legal Framework
Key Regulations:
| Legislation/EU Regulation | Area of Use | Reference |
|---|---|---|
| Regulation (EU) No. 305/2011 | Construction Products (CPR) | |
| Directive 2006/42/ES | Machinery Equipment (Machinery) | |
| Directive 2014/35/EU | Electrical Equipment (LVD) | |
| Directive 2014/30/EU | Electromagnetic Compatibility | |
| Directive 2014/68/EU | Pressure Equipment | |
| Directive 2014/53/EU | Radio Equipment |
For transport and construction containers, Regulation (EU) No. 305/2011 (CPR – Construction Products Regulation) is key. It establishes uniform rules for placing construction products on the market and their CE marking based on harmonized European standards.
When is CE Marking Mandatory and Which Containers Does It Apply To?
CE marking is mandatory only for products that are subject to special European directives and regulations. These groups include, for example, construction products, machinery equipment, electrical equipment, pressure vessels, etc.
Examples of Containers Subject to CE:
- Construction containers (residential such as shipping container homes, container houses, sanitary, technological, storage) intended for permanent installation in buildings
- Modular systems used in construction (kindergartens, offices, hospitals, etc.)
- Transport containers, if adapted for construction purposes – for example, as technical rooms, switchboards, fire-resistant storage, etc.
Note:
Standard transport shipping containers intended solely for transporting goods (ISO containers) fall under other international standards (e.g., CSC – Container Safety Convention) and CE marking applies to them only if they are intended as a construction product.
Harmonized Standards and Technical Specifications
Each type of product subject to CE has its own harmonized European standard (hEN), which defines basic characteristics, test methods, and required properties.
Examples of harmonized standards for containers:
- EN 1090-1 – Steel and aluminum structures (applies to many construction containers)
- EN 14509 – Composite sandwich panels (for containers with sandwich cladding)
- EN 13964 – Suspended ceilings (for container interior equipment)
- EN 16194 – Portable chemical toilets (for sanitary containers)
The list of harmonized standards and products is regularly published in the Official Journal of the European Union (OJEU – Official Journal of the European Union).
Conformity Assessment Process and Verification of Performance Stability
Conformity Assessment Systems
The conformity assessment process and verification of product performance stability is precisely defined by the harmonized standard and CPR regulation.
| System | Manufacturer Participation | Notified Body Participation | Product Type/Example |
|---|---|---|---|
| 1 | YES | YES (testing, audit) | High-risk construction elements |
| 2+ | YES | YES (manufacturing audit) | Steel structures, containers |
| 3 | YES | YES (type testing) | Some construction materials |
| 4 | YES (all) | NO | Low-risk products |
For containers, system 2+ is most commonly used, meaning the manufacturer ensures production control, while the notified body (certification authority) performs initial factory inspection and supervises production control.
Technical Documentation and Declaration of Performance
What Must Technical Documentation Contain?
According to EU Regulation No. 305/2011, technical documentation must be maintained and archived for the product, including:
- Description of the product and its intended use
- Drawings and assembly diagrams
- Description of the manufacturing process and materials used
- Test results (type tests, product tests, manufacturing control audits)
- List of harmonized standards used
- Copies of certificates and reports from notified bodies (if required)
- Declaration of Performance (DoP – Declaration of Performance)
Technical documentation must be retained for a minimum of 10 years after the product is placed on the market!
Declaration of Performance (DoP, PoV)
This document is an essential part of the CE process. It contains details about the product, its intended use, key properties, standards used, and manufacturer identification. The manufacturer is obliged to make the declaration available to customers upon request (both electronically and in printed form).
CE Marking on Container: Formal Rules
How Must the CE Label Be Executed?
CE marking must contain:
- CE logo in the prescribed shape and size (min. 5 mm)
- Last two digits of the year the marking was affixed
- Name and address of the manufacturer (or unique identification)
- Product type identification code
- Reference number of the Declaration of Performance (DoP)
- Levels or classes of properties listed in the DoP
- Reference to the harmonized technical specification used
- Where applicable, identification number of the notified body
- Intended use according to the harmonized standard
The CE label must be:
- Visible, easily legible, and indelible
- Ideally directly on the product, or on a label, technical sheet, or packaging
Role of Individual Entities in the Chain
| Entity | Obligations |
|---|---|
| Manufacturer | Prepares technical documentation, performs conformity assessment, issues DoP, marks product with CE |
| Importer | Verifies compliance and documentation, ensures their identification on the product/packaging |
| Distributor | Ensures the product is marked with CE, complies with legislation, has correct documentation |
| Notified Body | Performs testing, audits, certification according to harmonized standard |
Control and Supervision of CE Marking
Market surveillance is exercised in the Czech Republic by state authorities (e.g., Czech Trade Inspection Authority, State Labor Inspection Office, Technical Inspection of the Czech Republic, etc.). They may conduct product inspections, request technical documentation, and in case of non-compliance, impose fines, prohibit market placement, or order product withdrawal.
Sanctions:
- Fines ranging from hundreds of thousands to millions of crowns
- Prohibition of product placement on the market
- Obligation to withdraw the product from the market
- Possible criminal liability in case of endangering health or life
Most Common Misconceptions and Myths
- CE is not a quality certificate – it only indicates compliance with safety and regulatory requirements
- CE is not a certificate of origin – the product can come from anywhere if it meets the standards
- There is no “European CE certificate” – the mark is the result of independent assessment by the manufacturer, possibly with the participation of a notified body
- Optional certificates are not a substitute for CE – only CE allows legal placement of the product on the EEA market
Practical Examples: CE Marking on Containers
1. Residential Container Used as a Kindergarten
- Must meet static requirements (EN 1090-1), fire resistance, thermal insulation properties (EN 14509)
- Manufacturer performs type tests, establishes production control, cooperates with certification authority
- After successful assessment, issues DoP and marks with CE
2. Storage Container with Electrical Installation
- In addition to construction standards, must also comply with directives for electrical equipment (LVD, EMC)
- If it contains pressure or gas equipment, it may be subject to additional directives
- It is always necessary to correctly identify all applicable legislative requirements
Most Frequently Asked Questions in the Container Field
When is CE marking mandatory for a container?
If the container is intended for installation in a building, or is sold as a construction product, CE marking is mandatory.
What if I import a container outside the EU?
You must verify compliance with harmonized standards and ensure CE marking, otherwise it cannot be placed on the market.
How long must I archive documentation?
A minimum of 10 years after the last placement of the product on the market.
Who can help me with certification?
Notified bodies / certification authorities (e.g., TZÚS, Building Research Institute, Certification Company).
CE marking is a key element for the legal placement of containers on the European market as construction products. The manufacturer must comply with EU legislation, correctly identify applicable harmonized standards, create technical documentation, perform necessary tests, issue a Declaration of Performance, and properly mark the product. Failure to comply with these requirements can result in serious sanctions.
