Guide to Obtaining California Proposition 65 Testing Reports for Adhesives
I. Why Adhesives Require California Proposition 65 Testing
Adhesives often use various chemical raw materials in their production process, some of which may contain chemicals of concern under California Proposition 65. Adhesives are widely used in industries such as construction, furniture, electronics, toys, and packaging. Once products are sold in the California market, companies with annual sales exceeding $5 million must ensure their products comply with Proposition 65 requirements; otherwise, they may face lawsuits and hefty fines.
Furthermore, many brand owners and buyers require suppliers to provide California Proposition 65 testing reports as proof of supply chain compliance.
II. Main Items for Adhesive Testing
1. Commonly Detected Substances
| Detection Category | Specific Substance | Common Sources
| Heavy Metals | Lead, Cadmium, Mercury, Hexavalent Chromium | Pigments, Fillers, Catalysts
| Phthalate | DEHP, DBP, BBP, DINP, etc. | Plasticizer Raw Materials
| Formaldehyde | Formaldehyde and Formaldehyde Emitting Substances | Resin Adhesives
| Benzene | Benzene, Toluene, Xylene | Solvent-Based Adhesives
| Nitrosamines | Specific Nitrosamine Compounds | Certain Rubber-Based Adhesives
2. Testing Standards
EPA 3052 / 3050B: Determination of Heavy Metals by Microwave Digestion
CPSC-CH-E1001-08: Determination of Lead in Children's Products
ASTM D3421: Extraction Method for Plasticizers from Plastics
California Official List (Column) A): Over 800 regulated chemicals
III. Application Process
Step 1: Product Information Confirmation
Provide basic information about the adhesive (type, use, formulation list)
Confirm target market and customer requirements
Determine if full component analysis or targeted testing is required
Step 2: Sample Preparation and Submission
Prepare representative samples according to the testing institution's requirements
Fill out the testing application form, specifying the testing items and limit requirements
Send samples to a qualified laboratory (e.g., CPSC accredited laboratory, ISO 17025 certified laboratory, Dezewei Testing CNAS registration number: L8083)
Step 3: Laboratory Testing
Sample pretreatment (digestion, extraction, etc.)
Instrumental analysis (ICP-OES, GC-MS, HPLC, etc.)
Result interpretation and report preparation
Step 4: Report Issuance and Review
The laboratory issues a test report (including testing methods, results, and conclusions)
If substances exceeding the limits are detected, the cause must be analyzed and rectified.
Resubmission for testing may be necessary.
IV. Processing Time and Fee Reference
| Item | Reference Scope
| Testing Time | 5-7 business days (routine testing)
| Testing Fee | Depends on the number of tests required, approximately 500-1500 RMB per item
