Home Appliance Testing Reporting Guidelines under California Proposition 65
I. What is California Proposition 65?
California's Drinking Water Safety and Toxic Enforcement Act of 1986 (Proposition 65) requires that any product sold in California containing known carcinogenic or reproductive toxic chemicals (the list exceeds 900+) must meet compliance requirements through testing or by affixing a "WARNING" label.
Home appliances, containing various materials such as metals, plastics, electronic components, and solder, are a key category regulated by Proposition 65.
II. Common Hazardous Substances Required for Testing
| Category | Main Chemical Substances | Common Sources in Home Appliances
| Heavy Metals | Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr⁶⁺) | Solder, Metal Casing, Switches, Connectors
| Phthalate Salts | DEHP, BBP, DBP, DIBP, DINP, DPENP, DHEXP, DCHP | Power Cords, Plastic Casings, Insulation Materials
| Flame Retardants | PBBs, PBDEs, TBBPA, Deca-BDE | Circuit Boards, Plastic Casings, Cables
| Others | Formaldehyde, Benzene, Bisphenol A (BPA) | Coatings, Glues, Seals, Drinking Water Related Components
III. Scope of Testing for Home Appliances
Sampling and testing are usually conducted separately for accessible parts:
1. Metal Parts — Casing, Brackets, Screws, Springs, Heating Elements
2. Plastic Parts — 1. Housing, Knobs, Buttons, Panels, Fan Blades
3. Rubber/Elastomers – Seals, Gaskets, Feet
4. Coatings/Paints – Surface Coatings, Printed Markings
5. Cables/Power Cords – Copper Core, Insulation, Sheath
6. Solder/Electronic Components – PCB Boards, Solder Joints, Connectors
7. Glass/Ceramics – Display Screens, Heating Panels
8. Food/Water Contact Components (e.g., Electric Kettles, Coffee Makers) – Inner Tank, Water Pipes
IV. Test Methods and Standards
| Test Items | Reference Methods | Limit Requirements
| Lead (Pb) | EPA 3050B / 3052 / CPSC-CH-E1001-08 | Different limits apply to different materials
| Cadmium (Cd) | EPA 3050B / 3052 | Typically ≤ 300 mg/kg
| Phthalate | CPSC-CH-C1001-09.3 / EN 14372 | ≤ 1000 mg/kg per substance
| Flame retardants | GC-MS analysis | Subject to specific substance
| Formaldehyde | EPA 8315A / ISO 14184-1 | Typically ≤ 75 mg/kg (textiles)
Compliance for some substances can be determined through NSRL (No Significant Risk Level) or MADL (Maximum Permissible Dose Level).
V. Typical Contents of a Test Report
A complete Prop 65 test report should include:
Report number and date
Client/Manufacturer information
Sample information (name, model, batch)
Test methods and applicable standards
Test items and limits
Test results (data) for each component
Conclusion (Pass/Fail/Warning label required)
Laboratory accreditation (e.g., ISO 17025 accreditation)
Stamp and signature of the issuing organization
VI. Compliance Path Options
There are generally two compliance paths for home appliances entering the California market:
Path 1: Testing Compliance (Safest)
The levels of each hazardous substance in the product are below the safe exposure level.
A Prop 65 warning label may not be required on the product.
Recommended approach
Path 2: Adding a Warning Label
If the test results exceed the safe level, but the actual exposure under normal use is below the MADL,
A warning label must be added to the product, packaging, instruction manual, or online sales page:
"WARNING: This product can expose you to chemicals including [chemical name], which is..." Known to the State of California to cause cancer/birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
VII. Recommended Third-Party Testing Agencies
Domestic: Dezewei Testing CNAS Registration No.: L8083
It is recommended to choose an ISO/IEC 17025 certified laboratory.
VIII. Compliance Recommendations
1. Design Stage Involvement: Prioritize low-lead, phthalate-free, and low-cadmium materials when selecting product materials.
2. Supply Chain Management: Obtain SDS and test reports for raw materials from upstream suppliers.
3. Component-by-Component Testing: Sample the entire machine and components separately to avoid overlooking risky parts.
4. Monitor the Latest List: OEHHA updates its chemical substance list annually; dynamic monitoring is necessary.
5. Retain Test Reports: It is recommended to retain them for at least 3-5 years to prepare for potential litigation.
6. Online Sales Compliance: Prop 65 applies even when selling on platforms such as Amazon.
Risk Warning: California's Prop 65 has an extremely low threshold for prosecution, with penalties for violations reaching up to $2,500 per violation per day. Consumers and public interest organizations often file "line-by-line" lawsuits. It is strongly recommended that appliance exporters complete product testing before launching their products to avoid product recalls, fines, and damage to brand reputation.
