DTi is a domestic third-party testing and certification organization, providing one-stop solutions for the German LFGB standard. With an experienced engineering and business team with over twelve years of testing experience, we offer comprehensive support for all your testing and certification needs. The key steps and core requirements for obtaining German LFGB certification for plastic packaging bags integrate the latest regulations and practical tips:
I. Key Steps Before Certification
1. Material Composition Verification
- Identify the material type of the plastic packaging bag (e.g., PP/PE/PET/PVC, etc.). Test items vary significantly for different materials.
- If printed layers, coatings, or adhesives are present, separate labeling of the ingredients (e.g., ink, heat sealant) is required.
2. Laboratory Qualification Verification
- Select a CPSC-accredited laboratory (number ID: 1552, available on the official website). Reports from non-accredited laboratories will be rejected by Amazon.
II. Core Testing Process
A [Sampling Accessible Parts] --> B [Sub-Testing]
B --> C [Test Passed?] }
C --> | Yes | D [Generate Compliance Report]
C --> | No | E [Retest after Correction]
D --> F [Draft LFGB Certificate]
Specific Test Items (for Plastic Packaging Bags):
1. Sensory Testing
- Evaluate odor/taste migration (simulate real-world scenarios for oily foods).
2. Chemical Safety Testing
- Total Migration: Immerse in three simulated liquids (water, 3% acetic acid, and 10% ethanol) and measure the total amount of soluble matter.
- Heavy Metal Extraction: Limits for lead (≤0.05 mg/kg) and cadmium (≤0.01 mg/kg).
- Specific Substance Testing:
- PVC: Vinyl Chloride Monomer (≤1 mg/kg), Phthalates (7 types).
- PET: Antimony (≤0.04 mg/kg), Acetaldehyde Migration
3. Physical Performance Testing (if applicable)
- Heat seal strength and puncture resistance (to ensure no leakage during transport).
III. Document Drafting and Submission
1. Required Information for the LFGB Certificate
- Product description (including material and intended use), manufacturer and importer information (address/phone number);
- Testing laboratory name and qualification number;
- Knife and fork symbol (must be marked on the packaging).
2. Test Report Requirements
- Must include detailed data for all materials (e.g., multi-layer composite bags require separate testing for each layer).
IV. Amazon Audit Pitfall Avoidance Guide
1. Common Reasons for Rejection
- ❌ Failure to update to the latest standards (e.g., formaldehyde/flame retardant testing added in 2025);
- ❌ Missing importer information (Amazon sellers must provide their own or a partner's information);
- ❌ Failure to indicate the applicable temperature (e.g., "≤70°C"), resulting in excessive migration.
2. Cost Optimization Suggestions
- Batch testing of similar materials can reduce unit costs (e.g., PE bags of different sizes can be tested together).
V. Cycle and Cost Reference
| Step | Cycle
| Laboratory Testing | 5-10 Business Days
| Certificate Drafting and Review | 3-5 Business Days
| Expedited Service | 3-5 Business Days
Note: Costs vary depending on material complexity and the number of test items.
