Guide to Obtaining China RoHS Test Reports for Household Humidifiers
I. Why is China RoHS testing required for household humidifiers?
Household humidifiers (including ultrasonic, evaporative, and electric heating models) are classified as small home appliances and fall under the scope of mandatory China RoHS regulations. They contain numerous components—such as electronic parts, plastic housings, metal components, heating elements, motors, and PCBs—that pose a potential risk of exceeding limits for hazardous substances like lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs.
Obtaining a RoHS test report is a necessary credential for selling in the Chinese market, listing products on e-commerce platforms, and participating in tenders.
II. Application Process (Six Key Steps)
Step 1: Select a qualified testing agency
Prioritize third-party laboratories holding CMA (China Metrology Accreditation) and CNAS (China National Accreditation Service for Conformity Assessment) qualifications.
Verify that the agency's test reports are accepted by e-commerce platforms, government regulatory bodies, and customs authorities.
Verification method: Check the agency's qualifications via the "National Public Service Platform for Certification and Accreditation Information."
Step 2: Complete the application and prepare samples
Provide the product name, model, specifications, Bill of Materials (BOM), and product manual.
Sample quantity requirements:
Complete unit: Usually 1–2 units.
Large homogeneous materials: Provide at least 5–10 grams of each material type.
Disassembly requirements: Laboratories typically need to disassemble the product down to the homogeneous material level (single material)—e.g., plastic housing, control board PCB, copper core of power cords, heating elements, motor coils, etc.
Step 3: Laboratory testing (Core phase)
Testing methods
| Testing Stage | Method | Description |
| Initial Screening | XRF Fluorescence Spectrometer | Rapid screening for the presence of hazardous substances |
| Precise Quantification | ICP-OES, ICP-MS, AAS | Measuring content of metals such as lead, mercury, and cadmium |
| Organic Compound Analysis | GC-MS | Detecting PBBs and PBDEs |
| Hexavalent Chromium Specific Test | UV-Vis Spectrophotometry / Ion Chromatography | | Focus on testing for Cr⁶⁺ in platings and coatings
Key components of humidifiers to be tested
Plastic housing (ABS, PP materials): Test for cadmium, lead, PBB, and PBDE
Power cords and internal wiring: Test for lead and cadmium (PVC sheathing contains phthalate plasticizers)
Electric heating elements (for heating-type humidifiers): Test for lead content in solder joints
Ultrasonic atomizing discs (core components): Test for lead and cadmium in piezoelectric ceramic coatings
Control PCB: Test for lead content in solder and flame retardants (PBB/PBDE)
Motors and water tanks: Test for hexavalent chromium and mercury in metal coatings
LED indicators and switches: Test for cadmium in contact materials
Step 4: Issuance of test report
Testing turnaround: 5–7 working days (expedited service: 2–3 days)
Report contents: Test items, test methods, test results for each component, and compliance determination
The report must bear the CMA and CNAS qualification stamps plus the dedicated testing seal (Dezewei Testing CNAS registration number: L8083)
Report validity: Usually 1 year (requires annual renewal)
Step 5: Selection of applicable testing standards
| Standard Number | Scope of Application
| GB/T 26125-2011 | Testing for six categories of hazardous substances in electrical and electronic products (equivalent to IEC 62321)
| GB/T 39560 Series | New national standards (equivalent to the updated version of IEC 62321:2008)
| SJ/T 11364-2014 | Labeling requirements (marking for the restriction of hazardous substances in electrical and electronic products)
Step 6: Product labeling and packaging marking
Labeling must be applied according to regulations after passing the test:
Green "e" mark: Indicates the product fully complies with RoHS requirements
Orange "40" mark: Indicates the presence of hazardous substances and specifies the Environment-Friendly Use Period (EFUP)
Label location: Prominent position on the product body or packaging
Label content example: "e" or number "40" + Environment-Friendly Use Period (years)
III. Reference for testing costs and turnaround times
| Item | Standard Service | Expedited Service
| Testing Cost | 800–2,500 RMB/model | 1,500–3,500 RMB/model
| Testing Turnaround | 5–7 working days | 2–3 working days
| Report Language | Chinese (English version available upon request)
| Report Copies | Usually includes original + copy |
Reasons for cost differences: Product complexity, number of components, presence of multi-colored ink printing, requirement for extended phthalate testing, etc.
IV. Checklist of Required Documents
Prepare the following documents beforehand to expedite the process:
1. Testing application form (template provided by the agency)
2. Copy of the enterprise business license
3. Product manual (Chinese and English)
4. Product BOM (Bill of Materials/list of components and materials)
5. Product photos (including the complete unit and internal structure)
6. Information on key component suppliers (preparing SDS/Safety Data Sheets is recommended)
7. Sample submission form (to be included when shipping samples)
V. Important Notes and Pitfalls to Avoid
Common Misconceptions
1. Misconception 1: Thinking a single complete unit suffices for all testing—Wrong! The product must be dismantled down to the homogeneous material level; every component made of a different material requires testing.
2. Misconception 2: Using an RoHS report from another product—Wrong! Any change in product model, structure, or components necessitates re-testing.
3. Misconception 3: Relying solely on the complete unit report and ignoring the need for component-level testing—Wrong! CMA-accredited reports must clearly display test data for each homogeneous material.
4. Misconception 4: Thinking the report is valid forever once obtained—Wrong! You must monitor the validity period and update it in a timely manner.
Tips for Efficient Processing
Component supplier management: Require upstream suppliers to provide RoHS test reports or letters of commitment for raw materials.
Self-testing of key components: Pre-testing high-risk components—such as ultrasonic atomizers, power cords, and motors—is recommended.
Tracking version changes: Re-testing is recommended following changes to product appearance, internal structure, or component replacement.
E-commerce platform registration: Platforms like JD.com, Tmall, and Taobao require the upload of reports bearing dual CMA and CNAS accreditation.
Multi-platform utility: A single compliant report can be used across multiple platforms, avoiding the need for repeated testing.
