The national RoHS certification is a requirement of the "Catalogue of Restricted 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. A complete guide to the process of obtaining China RoHS testing (control of 10 hazardous substances) for audio-visual equipment (such as televisions, stereos, projectors, etc.), based on the latest 2025 standard GB/T 26572-2023 and practical points:
I. Core Testing Items and Limits (Updated in 2025)
China RoHS requires the control of 10 categories of hazardous substances in electrical and electronic products (actually 6 substances + 4 supplementary requirements):
| Hazardous Substances | Limit Requirements | Examples of High-Risk Components
| Lead (Pb) | ≤1000 ppm | Solder, glass screens, cable sheaths
| Mercury (Hg) | ≤1000 ppm | Backlight tubes, switch contacts (limit 5mg/tube)
| Cadmium (Cd) | ≤100 ppm | Batteries, pigment coatings, plastic casings
| Hexavalent Chromium (Cr⁶⁺) | ≤1000 ppm | Metal plating, screws, casing coatings
| Polybrominated biphenyls (PBBs) | ≤1000 ppm | Circuit board flame retardants, plastic casings
| Polybrominated diphenyl ethers (PBDEs) | ≤1000 ppm | Power adapters, cable insulation
| Phthalate esters (4 items) | DEHP+DBP+BBP+DiBP each ≤1000 ppm | Power cord PVC, remote control soft rubber buttons |
Note:
1. Starting in 2025, 4 new mandatory phthalate ester tests will be added (previously 6 substances);
2. Exemption: Lead content in solder ≤85% (exemption certificate required).
II. Processing Procedure (5 Steps)
1. Material Disassembly and Sample Preparation
- Disassembly Principle: Disassemble according to homogeneous materials (same composition) (e.g., plastic casing, circuit board, cables, etc.);
- Sample Quantity: 1 complete unit + 2 samples each of key components (screen, circuit board, power supply, etc.);
- Key Areas:
Television: LCD screen (mercury risk), power board (PBDE), speaker solder joints (lead)
Audio System: Cables (phthalates), metal casing plating (hexavalent chromium)
2. Selecting a CNAS Accredited Laboratory
- Qualification Verification: Check the [China Accreditation Service for Conformity Assessment] (DEZW Testing CNAS Registration No.: L8083) to confirm the laboratory's qualifications;
- Testing Standards:
- GB/T 26125-2023 (Methods for the Determination of Hazardous Substances)
- GB/T 39560-2025 (New Standard for Phthalate Esters)
3. Key Points of Testing Implementation
| Test Items | Methods
| Heavy Metals (Pb/Cd/Hg/Cr⁶⁺) | ICP-OES/XRF Screening + Chemical Titration
| Brominated Flame Retardants (PBB/PBDE) | GC-MS
| Phthalate Esters (4 items) | HPLC-MS/MS
4. Obtaining the Test Report
- Required elements of the report:
- Product model, batch number, and list of disassembled parts;
- Measured data + limit comparison table (e.g., "Cadmium: Not detected (<5ppm)");
- Laboratory CNAS stamp and signature (reports without the stamp are invalid).
5. Signing the Declaration of Compliance (DoC)
- Core content of the template:
[Manufacturer] declares: XX model televisions comply with GB/T 26572-2023 requirements,
The content of hazardous substances is below the limit (with test report number XXX).
Environmentally Friendly Service Life: 10 years
Waste Recycling Label: ✓
- Labeling Requirements: Products must bear the green e-label (size ≥ 5mm × 5mm).
III. Cost and Cycle Optimization Plan
| Project | Regular Cost | Expedited Plan (+50% cost)
| Basic Testing (6 items) | ¥6.00~8.00 | Report in 3 days
| Additional Testing for 4 Phthalate Items | +¥2.00~3.00 | +2 days
Cost-Saving Tips:
- Reuse EU RoHS report (requires additional 4 phthalate tests, saving 40% cost);
- Select typical models from the same product series for testing (covering 80% of components is sufficient).
IV. Solutions to High-Frequency Issues in 2025
1. Phthalate Exceeding Standards (e.g., DEHP > 1000ppm)
Replace with TPU cable (instead of PVC), cost increases by ¥2/meter but pass rate > 95%.
2. Hexavalent chromium plating is substandard.
Trivalent chromium passivation process (environmentally friendly alternative) is used; process certification documents are required.
3. Exemption Application Process
A [Submit Exemption Material List] --> B (Laboratory Assessment)
B --> C {Does it comply with Appendix B of GB/T 26572?}
C --> |Yes| D [Issuance of Exemption Appendix]
C --> |No| E [Modify Materials or Abandon Exemption]
