Smart wearable devices (such as smartwatches, fitness trackers, VR/AR headsets, smart headphones, and TWS Bluetooth earphones) exported to the California market must strictly comply with the requirements of California Proposition 65. Below is a complete guide covering product scope, testing items, procedures, costs, and key points to avoid pitfalls.
I. Which smart wearable products require certification?
Smartwatches (including straps and chargers)
Fitness trackers/motorcycle trackers
TWS true wireless Bluetooth earphones
VR/AR headsets and accessories
Smart glasses (including frames and nose pads)
Smart rings (such as the Ora Ring series)
Smart clothing (sportswear with sensors)
Accessories: Charging cables, silicone straps, leather straps, magnetic straps
Compliance principles: Finished products and accessible accessories must be tested. Products containing batteries also require compliance with UN38.3 and the Battery Directive.
II. Core Chemical Substances Required Testing
| Substance Category | Key Testing Items | Source Location
| Heavy Metals | Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr⁶⁺) | Metal Casing, Welding Points, Alloy Materials
| Phthalate | DEHP, DBP, BBP, DIBP (4 mandatory tests) | Silicone Straps, Plastic Casings, Wire Coatings
| Flame Retardants | PBBs, PBDEs, TBBPA, Deca-BDE | Circuit Boards, Plastic Casings, Battery Compartment
| Other | Formaldehyde, Polycyclic Aromatic Hydrocarbons (PAHs), Bisphenol A (BPA) | Straps, Skin-Contact Components, Charging Contacts
Special Reminder:
Since 2023, DIBP has been widely included in the testing list;
Leather/metal straps require additional testing for Cr⁶⁺ and PAHs;
Stricter limits apply to smart wearable products used by children (such as children's watches).
III. Compliance Process
Step 1: Self-Assessment and Material Preparation
Confirm the product's Bill of Materials (BOM)
Collect supplier information for accessories (watch straps, chargers)
List all parts that may come into contact with skin
Step 2: Select a Qualified Third-Party Laboratory
It is recommended to choose an ISO/IEC 17025 certified laboratory.
DEZEW Testing CNAS Registration Number: L8083
Confirm that the laboratory report is widely accepted in the US market (especially valued by US distributors and Amazon sellers).
Step 3: Sample Submission and Testing
Sample Quantity: Usually 2-5 finished products are required; disassembled parts may be necessary.
Testing Cycle: Regularly 5-7 business days, expedited to 3-5 days.
Report Validity: California Proposition 65 has no mandatory requirement, but it is generally recommended to renew every 1-2 years.
Step 4: Obtaining the Report and Continuing Compliance
The report should specify: product model, testing items, limit standards, and testing methods (e.g., ...). CPSC-CH-C1001-09.3), Result Determination
The report will be archived for review by US importers, Amazon, and cross-border e-commerce platforms.
IV. Fee Reference
| Product Complexity | Fee Range (RMB)
| Simple Products (e.g., single-color silicone watch straps) | 800 – 3000 RMB
Note: Basic 4 phthalates + heavy metals = starting package; PAHs, formaldehyde, and all California Proposition 65 items require separate pricing.
