As a product listed in China's RoHS mandatory catalog, computer monitors' compliance process directly impacts market access. The entire process can be summarized into three core stages: "testing as the foundation, declaration as the core, and labeling as the certification," requiring companies to control the entire chain from product design to market sales.
I. Core Processes for China RoHS Compliance (Applicable to Computer Monitors)
1. Preliminary Preparation: Clarifying Product and Testing Requirements
- Product Disassembly and Analysis:
Computer monitors need to be disassembled into homogeneous materials (such as screen panel, plastic casing, circuit board, connecting cables, metal bracket, etc.) to determine the type of material to be tested (metal/non-metal).
Key Considerations: The PVC material of internal connecting cables is prone to containing phthalates and requires special attention. *
- Document Preparation:
- Product manual, BOM (Bill of Materials)
- RoHS test reports for key components (e.g., power adapter, PCB board)
2. Core Step: Testing and Report Acquisition
- Laboratory Selection:
Must be a CNAS-accredited third-party organization (e.g., Dezeway Testing, CNAS registration number: L8083), with testing standards based on GB/T 26125-2011.
- Test Items:
Six mandatory hazardous substances: Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr⁶⁺), Polybrominated Biphenyls (PBBs), Polybrominated Diphenyl Ethers (PBDEs).
- Testing Cycle and Costs:
- Cycle: 5-10 working days (depending on the number of materials)
- Costs: 800-3000 RMB (Displays are typically tested using 5-10 different materials; testing costs for non-metallic materials are higher than for metallic materials)
3. Compliance Declaration and Information Submission
- Signing the Declaration of Conformity (DoC):
Companies must declare that their products comply with China's RoHS requirements. The format must include:
Product model and brand
Test report number and laboratory information
Explanation of compliance with hazardous substance limits
- Information Submission (for products listed in the catalog):
Submit product information through the China Electronics Standardization Institute (CESI) platform. No official review is required, but the information must be retained for 5 years for future reference.
4. Product Labeling and Market Access
- Affixing an Environmentally Friendly Service Life Label:
Label "Environmentally Friendly Service Life XX Years" (usually 10 years) on the back of the display or packaging. The format must comply with GB/T 26572-2011.
- No "Certificate Required":
China RoHS uses a "test report + Declaration of Conformity" as compliance documentation. There is no official unified certificate; companies can design their own compliance logo.
II. Common Misconceptions and Risk Mitigation
1. Misconception that "Testing = Certification":
China RoHS does not have an official certification certificate. Some organizations' so-called "RoHS certificates" are actually test reports; companies should be wary of excessive charges.
2. Component Compliance ≠ Whole Machine Compliance:
Even if the purchased power adapter has passed RoHS, the materials of the entire monitor (such as the casing paint and internal wiring harness) still need to be tested.
3. Report Validity:
Test reports do not have a fixed validity period, but retesting is required when product materials or manufacturing processes change.
III. Practical Suggestions for Enterprises
- Supply Chain Management: Require suppliers to provide RoHS test reports for key components (such as LCD panels and driver boards) to reduce the cost of testing the entire machine.
- Self-declaration template: Refer to the "Conformity Declaration Template for Restriction of Hazardous Substances in Electrical and Electronic Products" (2023 Revised Edition) issued by the Ministry of Industry and Information Technology.
- Processing in conjunction with energy efficiency labeling: Computer monitors must meet energy efficiency standards simultaneously. Energy efficiency labeling and RoHS testing can be applied for concurrently, shortening the overall processing time.
