Food contact materials (FCMs) are materials that will come into contact with food under normal or foreseeable use conditions, and do not themselves constitute part of the food. A Complete Guide to Testing Drinking Cups (GB4806 Food Contact Materials)
I. Testing Standards
The specific GB4806 sub-standard must be matched to the material of the drinking cup, and all products must comply with GB4806.1-2016 "National Food Safety Standard - General Safety Requirements for Food Contact Materials and Articles":
| Drinking Cup Material | Corresponding Testing Standard
| Stainless Steel (Thermos) | GB4806.9-2016 "Metallic Materials and Articles for Food Contact"
| Plastic Cup | GB4806.7-2016 "Plastic Materials and Articles for Food Contact"
| Ceramic Cup | GB4806.4-2016 "National Food Safety Standard - Ceramic Products"
| Glass Cup | GB4806.5-2016 "National Food Safety Standard - Glass Products"
| Silicone/Rubber Cup (including sealing ring) | GB4806.11-2016 "Rubber Materials and Products for Food Contact"
II. Core Testing Items
1. General Routine Items: Sensory requirements (no odor, no discoloration, no foreign matter), total migration, potassium permanganate consumption, heavy metals (as Pb)
2. Material-Specific Items:
Stainless Steel Cups: Lead, Cadmium, Chromium, Nickel, Arsenic migration
Ceramic/Enamel Cups: Lead (Pb), Cadmium (Cd) migration
Plastic Cups: Plasticizers (phthalates), Bisphenol A migration/residue, decolorization test
Silicone Cups: Potassium permanganate consumption, heavy metals, total migration
3. Labeling Verification: Product name, material (e.g., "Stainless Steel 06Cr19Ni10"), producer/distributor information, "For Food Contact" label or spoon/chopstick symbol must be included. Special usage requirements (e.g., temperature resistance range) must be clearly stated.
III. Processing Procedure
1. Choosing an Institution: You can choose Dezewei Testing, a third-party testing institution with CMA/CNAS accreditation (CNAS registration number: L8083).
2. Submitting Documents and Samples: Fill out the test application form, provide the product manual, and send 3-5 complete samples (must be consistent with commercially available products).
3. Laboratory Testing: The cycle is approximately 5-7 days, using professional equipment such as atomic absorption spectrometer and ICP-MS to complete the index determination.
4. Issuance of Report: A formal report will be issued after the test is passed. The report includes test items, standard basis, result interpretation, etc.
IV. Report Validity Explanation
1. The report itself is valid for 6 years under the laboratory management system.
2. E-commerce platforms (Taobao, Tmall, JD.com, etc.) only recognize reports issued within 1 year from the date of issuance.
3. Some buyers may limit the validity period of the report to 1-3 years, depending on the buyer's specific requirements.
V. Purchase and Testing Precautions
1. 1. Prioritize insulated cups made of 304/316 stainless steel, both of which meet the requirements of GB4806.9 standard. 304 is sufficient for daily use, while 316 offers stronger corrosion resistance.
2. For colored coated cups, pay close attention to coating migration risk and avoid using products with inferior coatings.
3. For children's drinking cups, pay extra attention to material safety. Avoid plastic products containing BPA and prioritize food-grade silicone and 316 stainless steel.
