Obtaining a GB 4806 Test Report for Baby Food Containers in China
Testing Overview
Baby food containers fall under the category of food-contact articles for infants and young children. For containers made of polypropylene (PP), the standard GB 4806.7 applies, while silicone versions must comply with GB 4806.11. Components such as sealing rings and printing inks must be separated and tested individually. Because products intended for infants and young children are subject to stricter regulations—often requiring testing under conditions that simulate high temperatures and exposure to fatty substances—these reports are essential for listing products on domestic e-commerce platforms, supplying supermarkets, and passing market surveillance inspections.
Standard Test Items
1. Sensory requirements: Color, odor, and absence of foreign matter.
2. Overall migration limit.
3. Potassium permanganate consumption.
4. Heavy metals (lead).
5. Decolorization test (for colored or printed products).
6. Specific migration limits based on material: Additional tests for monomers and low-molecular-weight substances are conducted according to the specific material (e.g., PP, silicone, PC, etc.).
Required Documentation
1. Test request form (specifying the material, microwave suitability, and applicable temperature range).
2. List of materials: Including the container body, sealing rings, printing inks, and adhesives.
3. Photographs of the product (focusing on food-contact surfaces and printed areas).
4. Finished product samples (samples with different colors or materials must be submitted separately).
Testing Process
1. Confirm the materials and intended usage scenarios to determine the appropriate testing protocol.
2. Submit the required documentation and send the samples.
3. The laboratory performs physical and chemical testing by immersing the samples in food simulants.
4. Data is reviewed; if the product passes, a CMA/CNAS-accredited GB 4806 test report is issued. If it fails, recommendations for corrective action are provided, and re-testing is available.
5. The report can be used for platform compliance audits, client verification, and regulatory spot checks.
Timeline and Important Notes
The standard turnaround time is 5–7 business days.
Any changes to the raw materials of the container, sealing rings, or ink formulations require re-testing. The test report is valid only for the specific samples submitted. Since these containers are intended for infants and young children, it is recommended to confirm with the retailer whether more stringent testing conditions are required.
