GB4806 testing is indeed an essential step. As glass baby bottles come into contact with infant food, they must be strictly tested according to national standards to ensure safe use.
Guidelines for Obtaining Test Reports for Glass Baby Bottles (China GB4806 Food Contact Materials)
I. Core Testing Standards and Scope of Application
- Specific Standard: GB4806.5-2016 "National Food Safety Standard - Glass Products"
- General Requirements: Must also comply with GB4806.1-2016 "General Safety Requirements for Food Contact Materials and Articles"
- Applicable Products: All glass baby bottles designed for infant feeding (including the bottle body, graduation markings, and matching silicone nipples must individually comply with GB4806.2-2015)
II. Mandatory Testing Items (Special Item for Glass Baby Bottles)
| Testing Items | Test Methods
| Lead (Pb) Migration | GB 31604.34-2016
| Cadmium (Cd) Migration | GB 31604.24-2016
| Inner Surface Water Resistance | GB/T 4548-1995 (Grading Test for Water Resistance of Glass)
| Internal Stress | GB/T 4545-2007 (Polarized Optical Stress Meter Test)
| Mechanical Shock Resistance | GB/T 6552-2015 (Falling Ball Impact Test)
III. Complete Application Process (Including Special Requirements for Infant Products)
1. Document Preparation Stage
- Required Documents:
Product Instructions (must be labeled "Food Contact Use" and applicable temperature range)
Material Certificate (Glass grade such as high borosilicate 3.3, soda-lime glass, etc.)
Brief Description of Manufacturing Process (e.g., whether it includes printing ink, baking decoration process)
- Sample Requirements:
Three complete samples are required (including bottle body, bottle cap, and nipple; the nipple must be separately packaged and the material must be indicated)
If the bottle body has colored patterns, an additional material description for the patterned area is required.
2. Key Points for Selecting a Testing Institution
- Qualification Requirements: Must possess CMA certification (China Metrology Accreditation) and CNAS accreditation.
- Experience with Infant Products: Prioritize institutions with a history of testing baby bottles (e.g., Dezeway Testing, CNAS registration number: L8083)
- Report Validity: The report's purpose must be clearly stated (e.g., a CMA stamp is required for e-commerce platform entry, and an English report is required for export).
3. Testing Cycle and Fees
- Cycle: Regular 5-7 working days (lead and cadmium migration testing requires 48 hours of immersion), expedited 3 working days (fee increases by 50%)
- Fees: Approximately 800-2500 RMB per test for single-material glass baby bottles (includes 5 mandatory tests; an additional 800-1200 RMB is required if a silicone nipple is included).
IV. Report Review and Labeling Standards
1. Verification of Key Report Information
- Must include: Testing standard number (clearly marked GB4806.5-2016), testing institution's CMA/CNAS logo, and sample chromatograms (e.g., raw data from lead and cadmium testing).
- 1. The nipple must have its GB4806.2-2015 test results listed separately (e.g., N-nitrosamine release < 0.01 mg/kg).
2. Mandatory Labeling Information
Example of Compliant Label:
【Food Contact】Glass Baby Bottle
Material: High borosilicate glass (bottle body), silicone (nipple, GB4806.2)
Manufacturer: XXX Co., Ltd.
Standards: GB4806.5-2016, GB4806.1-2016
Precautions: Do not use for microwave heating/sudden heating/cooling.
V. Common Non-Compliance Items and Mitigation Solutions
- Lead and Cadmium Exceeding Standards Risk:
→ Avoid using recycled glass or inferior color glazes; choose lead-free crystal glass or high borosilicate glass.
- Internal Stress Exceeding Standards:
→ Sufficient annealing treatment is required after production (recommended annealing temperature 560-600℃, holding for 2 hours).
- Missing Label Information:
→ The label must be marked "for food contact use" and cannot be vague statements such as "heat resistant" or "non-toxic".
