Obtaining a China GB4806 Test Report for Ceramic Casseroles
Ceramic casseroles fall under the category of ceramic products used as food-contact materials; the core standards applicable are GB4806.4 (Ceramic Products) and GB4806.1 (General Requirements).
I. Test Items
| Item | Limit Requirement
| Lead (Pb) release | ≤0.5 mg/L (flatware: ≤0.8 mg/dm²)
| Cadmium (Cd) release | ≤0.05 mg/L (flatware: ≤0.07 mg/dm²)
| Sensory test | Normal color/luster, no off-odors, no discoloration
| Appearance quality | Intact glaze, no damage
II. Application Process
1. Preliminary consultation: Confirm product dimensions (deep vs. flatware), glaze type, and presence of decorations (decals, gold rims).
2. Select an agency: Choose a testing agency with CMA accreditation (e.g., Dezewei Testing, CNAS Registration No.: L8083).
3. Complete application: Provide product information, intended use, and types of food contact.
4. Submit samples: Typically, 3–5 complete samples are required.
5. Testing turnaround: Standard 7–10 working days; expedited service available.
6. Report Issuance: Includes test results, compliance assessment against standards, and report validity period.
III. Costs and Validity
Basic Package: 800–2,500 RMB (includes lead/cadmium release testing and sensory evaluation).
Report Validity: Typically 5 years; however, re-testing is required if manufacturing processes or raw materials change.
IV. Important Considerations
Deep vs. Flat Distinction: Limits differ between deep vessels (depth ≥ 2.5 cm) and flat vessels; shallow pots (e.g., clay pot lids) are classified under the "flat" standard.
Decorated Areas: Hand-painted sections, decals, and gold-rimmed areas require priority testing, as pigments in these areas carry a higher risk of lead and cadmium contamination.
Prioritize Underglaze Decoration: Using underglaze techniques is recommended to minimize heavy metal risks at the source.
Initial Testing: A comprehensive baseline test is recommended; subsequent testing can focus solely on periodic monitoring of lead and cadmium levels.
Sales Requirements: Documentation is mandatory for listing in food-related categories on platforms like JD.com and Tmall, as well as for sales in brick-and-mortar supermarkets.
V. Compliance Recommendations
Simultaneously apply for a Production License (SC) or file a record for food-related products.
For export products, it is recommended to simultaneously conduct testing for EU Regulation 1935/2004 and US FDA compliance.
Retain records of raw material procurement and glaze formulations to ensure traceability.
