Plastic Hardware California 65 Testing Report Process
1、 Overview of California Regulation 65
California Proposition 65, also known as the 1986 Drinking Water Safety and Toxic Substances Enforcement Act, is one of the most influential consumer protection regulations in California, USA. The regulation requires companies to provide consumers with "clear and reasonable warnings" about the presence of chemicals in their products that may cause cancer, birth defects, or other reproductive harm.
For plastic and hardware products, common substances of concern include:
Phthalates (such as DEHP, DBP, BBP): commonly found in plastic parts
Bisphenol A (BPA): commonly found in polycarbonate plastics
Heavy metals (lead, cadmium, nickel): may exist in hardware metal components or surface coatings
Flame retardant: Some plastic parts may contain
2、 Preparation before testing
1. Product information collection
Before formal inspection, enterprises need to prepare complete product technical information, including but not limited to:
Product Material List (BOM)
Material composition description of each component
Overview of Production Process Flow
Expected sales area and target market
2. Material disassembly and identification
Plastic hardware products are usually composed of multiple composite materials, and testing agencies need to disassemble and analyze them one by one:
|Component Category | Typical Materials | Testing Focus
|Plastic shell/bracket | PC, ABS, PP, PVC | ortho benzene, flame retardant BPA
|Metal Hardware | Zinc Alloy, Copper, Stainless Steel | Lead, Cadmium, Nickel Release
|Coating/Ink | Paint, Electroplated Coating | Total Heavy Metal Content
|Connectors/Fasteners | Nylon, POM | Specific Additives
3. Laboratory qualification confirmation
When selecting a testing institution, the following qualifications and certifications should be carefully checked:
CMA (China Metrology Certification)
CNAS (National Laboratory Accreditation)
California 65 accredited laboratory qualification
International mutual recognition agreements (such as ILAC-MRA)
3、 Detailed steps of the detection process
Phase 1: Sample reception and registration
After receiving the sample, the testing agency will perform the following operations:
Verify the consistency between the sample information and the commission order
Identify the samples with unique numbers
Take sample appearance photos for archiving
Develop a testing plan based on product characteristics
Phase 2: Chemical analysis testing
According to the type of product material, corresponding testing methods are adopted:
Plastic component testing
GC-MS (gas chromatography-mass spectrometry): used for analyzing volatile organic compounds and phthalates
LC-MS/MS (liquid chromatography tandem mass spectrometry): detection of semi volatile substances
HPLC (High Performance Liquid Chromatography): Quantitative Analysis of Specific Compounds
Metal hardware testing
ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer): Total amount of heavy metals such as lead, cadmium, mercury, arsenic, etc
ICP-MS (Inductively Coupled Plasma Mass Spectrometer): Detection of Trace Heavy Metals
EN 1811/ISO 12870: Nickel Release Test (applicable to parts in direct contact with the skin)
Phase Three: Assessment and Judgment of Results
After the testing is completed, the laboratory will evaluate against the California Proposition 65 checklist:
1. Check whether the product contains chemicals that have been listed in the law
2. Calculate the exposure levels of each substance
3. Conduct compliance assessment against the 'Safe Harbor Levels'
4. Evaluate whether warning signs need to be labeled
Phase Four: Report Preparation and Issuance
The testing report usually includes the following core contents:
Sample description and testing conditions
Specific methods for each testing item
Raw detection data and spectra
Result determination and compliance recommendations
Issuance Date and Validity Period Explanation
4、 Cycle and Cost
|Project | Regular Cycle | Urgent Cycle | Cost Reference
|Single material testing | 3-5 working days | 1-2 working days | 500-1000 yuan
|Complete product testing | 7-10 working days | 3-5 working days | 1000-3000 yuan
Cost influencing factors:
Product complexity and number of components
Quantity and depth of testing items
Do you need expedited service
Report language version (if required in both Chinese and English)
5、 Compliance labeling requirements
According to the test results, the enterprise needs to take corresponding compliance measures:
Scenario 1: No restricted substances detected
The product can be labeled with the statement 'No California 65 warning label' and sold normally in the California market.
Scenario 2: Detected substance but below safe harbor level
It can still be sold normally, but it is recommended to keep the testing report for future reference.
Scenario 3: Detected substances exceeding the safe harbor level
The following warning must be marked on the product or packaging:
Warning: This product contains chemicals known to cause cancer, birth defects, or other reproductive harm in California.
Warning signs must meet the following requirements:
Clear and readable font (in English)
Clearly visible location
Do not use misleading statements
6、 Continuous compliance recommendations
1. Supplier management: Require raw material suppliers to provide a compliance statement (SDS/CoA)
2. Regular re inspection: Re evaluation is required when there are changes in the batch of raw materials
3. Regulatory tracking: California's 65 list is regularly updated (with approximately 10-20 new substances added each year)
4. Document archiving: Keep the test report for at least 3 years
5. Supply chain communication: Timely communicate compliance requirements to downstream partners
If you need to further understand the testing plan for specific product categories or obtain a quotation, please provide a list of product materials and detailed information on testing requirements.
