Guide to GB4806 Compliance for Coffee and Milk Tea Cups
Coffee and milk tea cups are typical food-contact materials; products sold within China must comply with the GB4806 series of standards. The following overview covers three key aspects: applicable standards, testing items, and the compliance process. I. Common Cup Materials and Corresponding Standards
| Material | Applicable Standard | Typical Products
| Paper Cups/Bowls (Coated) | GB4806.8 (Paper) + GB4806.7 (Plastic Coating) | Disposable coffee cups, milk tea cups
| Plastic Cups | GB4806.7 | PP/PS/PET cold drink cups, plastic milk tea cups
| Ceramic Cups | GB4806.4 | Coffee cups, mugs
| Glass Cups | GB4806.5 | Glass coffee cups, milk tea cups
| Stainless Steel Cups/Vacuum Flasks | GB4806.9 | Vacuum flasks, straw cups
| Silicone Cups/Straws | GB4806.11 | Silicone straws, silicone cup sleeves
| Aluminum Foil/Composite Cups | GB4806.9 + GB4806.7 | Aluminum foil coffee capsules, takeaway cup lid films
II. Key Testing Items
Paper Cups/Milk Tea Cups
1. Sensory test: Color, odor, foreign matter
2. Evaporation residue (4% acetic acid, 10% ethanol, n-hexane, water): Total migration
3. Potassium permanganate consumption: Reflects total leachable organic matter
4. Heavy metals: Lead, cadmium, arsenic, mercury, chromium
5. Fluorescent whitening agents (specific to paper cups)
6. Formaldehyde (specific to paper cups)
7. Decolorization test (immersion in colorant, alcohol, and cold food oil)
8. Microbial limits (case-dependent)
Plastic/PP Cups
Phthalates (6 types), Bisphenol A (BPA)
Specific migration (depending on material)
Decolorization test
Ceramic/Stainless Steel Cups
Lead and cadmium leaching (critical for ceramics)
Stainless steel: Migration of alloying elements such as chromium, nickel, and manganese
Vacuum flasks: Sealing integrity, thermal insulation performance
III. Compliance Process
Step Step 1: Preparation of Documentation
Product specifications and material descriptions
List of raw materials (PE-coated paper, ink, adhesive, etc.)
Supplier qualifications
Step 2: Sample Submission for Testing
Quantity: 3–5 complete finished products (including accessories such as lids and straws)
Select a testing agency with dual CMA and CNAS accreditation (e.g., Dezewei Testing, CNAS Registration No.: L8083)
Step 3: Testing and Reporting
Turnaround time: 5–7 working days
Cost range: 1,000–4,000 RMB (depending on the number of test items)
Step 4: Compliance Determination and Labeling
If all tests pass → CMA test report issued
Product may be labeled "Food Grade" or "For Food Contact Use"
Recommended label for outer packaging: "This product complies with the GB 4806 National Food Safety Standard"
IV. Compliance Risk Warnings
E-commerce platform requirements: Platforms such as JD.com, Tmall, and Douyin require merchants to upload GB 4806 reports for food-contact products before listing; failure to do so may result in delisting or penalties.
Common causes of non-compliance:
Excessive fluorescent whitening agents in paper cups
Excessive heavy metal migration from ink
Excessive evaporation residue from the inner cup coating
Printed patterns located in areas that come into direct contact with food
V. Recommendations for Compliance
1. Source control: Require suppliers of PE-coated paper, ink, and adhesive to provide declarations of conformity and third-party test reports.
2. Material verification: Select the appropriate standard based on the actual cup material to avoid mismatches.
3. Batch stocking for brands: Mandatory testing of the initial batch (same material and process); subsequent quarterly spot checks.
4. Record keeping: Retain test reports for at least 3 years for future reference.
Conclusion: Coffee and milk tea cups are subject to strict regulatory oversight under the GB 4806 framework. It is recommended to conduct systematic testing of materials and finished products prior to production to ensure a smooth approval process for e-commerce platforms and regulatory compliance in the market.
