This article provides a detailed explanation of the cycle and process for California Prop 65 (CA65/Prop 65) testing and certification of metal products, integrating the latest regulatory requirements and practical key points:
I. Core Certification Process and Cycle
1. Preliminary Preparation
- Confirmation of Testing Items:
Metal products require focus on testing for lead (Pb) and cadmium (Cd) migration:
- Lead limit: ≤100ppm for general components, ≤90ppm for coatings/paints
- Cadmium limit: ≤300ppm (stricter for jewelry products)
- Sample Requirements:
Provide 3-5 representative samples of finished products and accessible components (e.g., metal fittings and welds).
2. Laboratory Testing Phase (Turnaround 5-7 business days)
- Testing Standards:
EPA 3050B (heavy metal leachability) and other standards are used.
- Key Steps:
- Surface material testing (prioritizing human contact areas);
- Complex products (e.g., coated metal jewelry) require layered testing.
- Cycle Differences:
- Basic Testing (Lead + Cadmium);
- Additional Testing Items (e.g., Phthalates, Nickel): Extended to 7-10 working days.
3. Report Review and Certification
- The laboratory will issue a test report in both Chinese and English, which must include:
- California Proposition 65 referenced standards (e.g., CP65 list number);
- Clearly marked "Pass/Fail" conclusion.
- Certification documents will be issued upon passing the test; no certificate is required; the report serves as proof of compliance.
4. Labeling and Market Compliance
- If the test exceeds the standard, the product must be labeled with a warning label, using a format such as:
⚠️ *"WARNING: This product contains lead, a chemical known to cause cancer and reproductive harm."*
II. Key Considerations
1. Factors Affecting Cycle Time:
- Material complexity (e.g., alloys and electroplating with increased test items);
- Laboratory schedule (may be delayed during peak season).
2. Regulatory Dynamics:
- The California 65 list is updated annually, and reports have no fixed validity period; retesting is required as regulations are revised.
3. Cost Range:
- Basic Tests (Lead + Cadmium): ¥500-1500/item;
III. Optimization Suggestions
- Laboratory Selection:
Preferably select institutions with CNAS/CMA accreditation (such as Dezewei Testing) to ensure their reports are recognized by platforms like Amazon.
- Pre-Inspection and Self-Check:
Perform internal screening of high-risk areas such as plating layers and solder joints to reduce the risk of retesting.
- E-commerce Compliance:
When selling on platforms like Amazon, a warning statement must be added to the product description page.
