China's RoHS certification is a requirement of the "Catalogue of Compliance with Standards for the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products," issued in 2019 by the State Administration for Market Regulation and the Ministry of Industry and Information Technology. According to the requirements of China's "Measures for the Administration of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Products" (China RoHS 2.0), based on historical conversations and search results, the following materials are required for adhesives applying for China RoHS testing:
I. Core Application Materials
1. Application Form and Letter of Guarantee
- Complete the application form provided by the testing agency (indicate the report language: Chinese/English);
- Sign the Letter of Compliance, pledging that the product complies with China RoHS limits.
2. Product Technical Documentation
- Product Manual or Specification: Describes the adhesive's composition, application, and operating conditions;
- Bill of Materials (BOM): Detailed listing of all raw materials and supplier information (critical items).
II. Sample Requirements
1. Quantity and Specifications
- Single-material adhesive: Provide at least 50-100 grams of sample;
- Multi-component adhesive (e.g., adhesive A/B): Provide at least 30 grams of sample for each component.
2. Special Requirements
- If testing a plated/coated area, the material must be separately indicated and sufficient raw material must be provided.
- Sample packaging must be labeled with the product name, model, and batch number.
III. Supporting Documents (Expedited Testing Process)
1. Component Test Report (if available)
- If the adhesive contains pre-inspected, qualified raw materials (e.g., resin, solvent), provide the corresponding RoHS report.
2. Product Structure Diagram
- Simple cross-sectional view or component distribution diagram to facilitate laboratory identification of test points.
3. Quality Control Documents
- Production process control diagram, supplier compliance declaration, etc.
IV. Notes
1. Integration of New and Old Standards
- Starting in 2023, China RoHS will add restrictions on four new phthalates (DEHP/BBP/DBP/DIBP). Verification that testing covers all 10 hazardous substances is required.
2. Material Consistency
- Formula changes require retesting to ensure that the BOM and the sample composition exactly match.
3. Report Timeliness
- Test reports are typically issued within 5-7 business days and are valid for one year (unless there are material or process changes).
Summary of the Process
A [Prepare Materials] --> B [Fill Out Application Form + BOM]
B --> C [Provide 50-100g Sample]
C --> D [Submit Supporting Documents]
D --> E [Laboratory Testing]
E --> F [Obtain Report]
Key Tips:
- Prioritize laboratories with CMA/CNAS accreditation (such as Dezewei Testing);
- For adhesives, pay special attention to the migration risks of phthalates and heavy metals (lead and cadmium).
