Exporting interlocking toys to the EU does indeed require EN71 certification, which is crucial for compliant entry into the European market. The application process mainly includes determining the testing items, preparing documents, and sample testing.
I. Core Testing Items for EN71 Certification of Interlocking Toys
Interlocking toys (such as building blocks, assembly models, etc.) require close attention to the following standards:
- EN71-1: Physical and Mechanical Properties
- Testing the dimensions of interlocking parts (to prevent children under 3 years old from swallowing small parts), edge sharpness, tensile/torsional strength (to prevent parts from falling off), and structural stability (to prevent the risk of collapse).
- EN71-2: Flame Retardancy
- If the toy contains flammable materials such as fabric or paper (e.g., decorative stickers, fabric accessories), the burning rate and flame spread must be tested.
- EN71-3: Migration of Specific Elements
- Testing the leaching levels of 19 hazardous elements (such as lead, cadmium, barium, etc.) in the interlocking materials, especially colored plastic parts and coatings, which require separate testing.
- EN71-9: General Requirements for Organic Compounds (if applicable)
- If adhesives, inks, or other chemicals are used, the limits for VOCs (volatile organic compounds) and plasticizers (such as phthalates) must be assessed.
II. Complete Certification Process
1. Preliminary Preparation
- Determine Product Category: Clearly define the applicable age (e.g., 3+, 6+), material (plastic/wood/metal), and whether it contains electronic components to accurately match testing items.
- Technical Documentation Preparation:
- Product manual, design drawings (indicating component dimensions and material composition);
- Bill of Materials (BOM), distinguishing between components of different materials/colors;
- Material Safety Data Sheets (MSDS), especially compliance certificates provided by suppliers for plastic particles, coatings, etc.
2. Selecting a Certification Body
- Select an EU-recognized notified body (e.g., DEZEW Testing CNAS registration number: L8083) or a domestic CNAS-accredited laboratory (test reports must be recognized by the EU).
3. Sample Testing
- Sample Submission: Representative samples (e.g., plastic building blocks of different colors, assembled products) are required depending on the number and material of the components.
- Testing Cycle: Approximately 5-7 working days for standard items (EN71-1/-2/-3).
4. Document Review and Certificate Issuance
- The laboratory reviews the technical documents and test reports. After confirming that the product meets the requirements of the EN71 standard, a CE certification certificate is issued (some institutions only provide test reports; the company must then sign an EC Declaration of Conformity).
5. Affixing the CE Mark
- The CE mark (no less than 5mm in size and proportionally correct) must be affixed to the product or packaging as required, and technical documents must be retained for at least 10 years for future reference.
