China RoHS Testing Process for Smartwatches and Smart Bands
Testing Overview
Smartwatches and smart bands fall under the scope of the 2026 edition of the China RoHS compliance management catalog. They are subject to the standard GB 26572-2025, which regulates 10 hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), and four phthalates (DEHP, DBP, BBP, and DIBP). These requirements take effect on August 1, 2027. Manufacturers typically submit products for testing in advance to prepare inventory, facilitate online platform listings, address potential market surveillance inspections, and provide supporting documentation for self-declarations of conformity.
Smartwatches and smart bands feature complex structures composed of various distinct homogeneous materials, such as plastic casings, silicone/TPU straps, screen glass, PCBs, batteries, connectors, metal frames, electroplated components, inks, adhesives, buttons, and foam. Coatings, inks, and electroplated layers must be separated and tested individually; testing the device as a whole is insufficient. Given that straps are in prolonged contact with the skin, the control of phthalates is a key priority. Components that meet the criteria for the exemption list may be eligible for an exemption.
Standard Testing Scope
Comprehensive testing for the 10 hazardous substances under China RoHS. The laboratory first conducts an initial screening using X-ray fluorescence (XRF) to detect heavy metals and total bromine. Materials identified as high-risk during this screening undergo precise quantitative chemical analysis. Heavy metals are analyzed via ICP (inductively coupled plasma) spectrometry, hexavalent chromium via spectrophotometry, and brominated substances and phthalates via GC-MS (gas chromatography-mass spectrometry), in accordance with the GB/T 26125 testing methodology. Required Documentation
1. Testing Request Form (must include product model, name, intended use, and brand)
2. Bill of Materials (BOM) detailing all components, materials, and surface treatment processes
3. Photographs of the product (front and back), with individual components labeled
4. Samples of each homogeneous material (separated/disassembled)
5. Specification of requirements: Indicate whether you need only a test report, or if you also require documentation for the national voluntary RoHS certification or the "Self-Declaration" submission for the Ministry of Industry and Information Technology (MIIT) platform.
Process
1. Project Confirmation: Review product structure, materials, and processes; finalize the homogeneous material breakdown plan, testing scope, pricing, and turnaround time.
2. Submission: Provide the required documentation and send the samples; the laboratory will register the receipt of samples.
3. Sample Preparation: Disassemble the product into homogeneous materials and prepare them for testing.
4. Initial Screening: Conduct XRF (X-ray fluorescence) screening; if any items exceed limits, perform precise chemical analysis.
5. Data Review: Internal verification and audit.
6. Reporting: If all items pass, a CNAS-accredited China RoHS test report is issued. If any items exceed limits, you will be notified, provided with recommendations for material rectification, and offered the option for re-testing.
7. Additional Support (as needed): Provision of RoHS labeling templates, hazardous substance information tables, and self-declaration documentation—required for submission to the MIIT China RoHS Public Service Platform, e-commerce platform compliance reviews, and market regulatory inspections.
Turnaround Time and Important Notes
Standard turnaround time is 5–7 business days.
If there are any changes to raw materials, masterbatches, strap compounds, electroplating/coating processes, or ink formulations, new samples must be submitted for testing.
The test report is a "type test" report and is valid only for the specific samples submitted. Once the "Compliance Catalog" (for products subject to mandatory RoHS requirements) is officially implemented, enterprises will be required to complete a conformity assessment (via self-declaration or national voluntary certification), for which this test report serves as supporting documentation.
