I. Basic Background of California Proposition 65
Full Name of the Proposition: California Safe Drinking Water and Toxic Enforcement Act (Proposition 65)
Purpose of Control: To protect California residents and drinking water sources from harmful substances, requiring companies to provide clear warnings about carcinogenic/reproductive toxic chemicals in their products.
Control List: As of 2026, it includes approximately 800 chemicals, commonly found in smart wearable devices, including:
Heavy Metals: Lead, Cadmium, Nickel
Organic Compounds: Phthalate (DEHP, DBP, etc.), Polycyclic Aromatic Hydrocarbons (PAHs)
Plastic Additives: Short-Chain Chlorinated Paraffins
II. Key Testing Points for Smart Wearable Devices
Testing Based on Product Material:
| Component Type | Key Detected Substances | Safe Harbor Limit Reference
| Plastic Shell/Strap | Lead, Cadmium, Phthalate | Lead < 100 ppm, Cadmium < 40 ppm
| Metal Components (Frame/Buttons) | Lead, Cadmium, Nickel Release | Nickel < 0.5 μg/cm²/week
| Circuit Board/Solder | Lead and Tin Compounds | Lead <100ppm
| Battery Components | Cadmium and Mercury | Cadmium <20ppm
III. Testing Process
1. Product Analysis:
Provide BOM (Bill of Materials) and product photos.
Laboratory engineers determine the testing plan based on the materials.
2. Sample Requirements:
1-2 complete testing machines
Or 2-3 samples of each material.
3. Testing Cycle:
Standard 5-7 working days, expedited to 3 working days.
4. Report Content:
Sample information, testing methods, test results
Comparison with safe harbor standards
Laboratory accreditation certificate
IV. Compliance Recommendations
1. Report Validity:
Valid indefinitely if there are no changes to product design or regulations.
Retesting is recommended if raw material suppliers change.
2. Important Notes:
You must choose a laboratory with CPSC accreditation or ISO/IEC 17025 certification (e.g., Dezeway Testing CNAS registration number: L8083).
Platforms such as Amazon may require specific laboratory qualifications; please confirm in advance.
3. Follow-up Responses:
If the test results are satisfactory: The report can serve as proof of compliance.
If the test results exceed the limits: A California Proposition 65 warning label must be affixed before the product can be sold.
