Processing of GB4806 Test Report for Ceramic Tea Set in China

Guidelines for Handling GB4806 Test Reports for Ceramic Tea Sets in China

1、 Which ceramic tea sets need to undergo GB4806 testing

When ceramic tea sets are produced, sold, or imported within China, any components that come into direct contact with tea or hot water must comply with the requirements of the GB4806 national food safety standard. Mainly includes:

Teapot, teacup, fragrance cup

Tea tray, tea sea, tea tray

Tea filter, filter screen, fair cup

Tea jar, tea storage jar

Tea clips, teaspoons and other supporting utensils

Judgment criteria: Whether the product has direct contact with food (tea) and whether it is sold in the Chinese market. As long as these two conditions are met, GB4806 testing must be conducted.

2、 Applicable national standard number

The GB4806 series standards related to ceramic tea sets mainly include:

|Standard Number | Scope of Application

|GB4806.1-2016 | General Safety Requirements for Food Contact Materials and Products

|GB4806.3-2016 | National Food Safety Standard Ceramic Products

|GB4806.4-2016 | National Food Safety Standard Enamel Products

Among them, GB4806.3-2016 is the core applicable standard for ceramic tea sets.

3、 Handling process

Step 1: Confirm product information and applicable standards

Communicate with the testing agency to clarify the material type (overglaze color, underglaze color, underglaze color), firing process, temperature range for use, and other information of the tea set. Ceramic products with different processes and uses may have different testing items and limit requirements.

Step 2: Submit application and samples

Fill out the food contact material testing application form, provide product samples (usually 2-3 pieces per specification), product description, material list, and other information. The sample should be able to represent the material formula and process of actual production.

Step 3: Laboratory testing

Laboratories with CMA/CNAS qualifications shall conduct relevant testing on ceramic tea sets in accordance with the requirements of GB4806.3-2016 standard. The testing cycle is usually 5-7 working days.

Step 4: Report Issuance and Review

After the laboratory completes the testing, a testing report will be issued. The report includes product information, testing items, testing methods, testing results, judgment conclusions, etc. After receiving the report, enterprises should carefully verify the accuracy of the information.

4、 Main testing items

According to GB4806.3-2016 "National Food Safety Standard Ceramic Products", the main testing items for ceramic tea sets include:

1. Sensory requirements

Check whether the ceramic surface is clean and free of attachments, and whether the soaking solution has no odor or peculiar smell. This project mainly evaluates whether the product will produce uncomfortable sensory changes during use.

2. Migration of lead and cadmium

This is the most essential testing item for ceramic products. Lead and cadmium are common glaze additives, and if their migration exceeds the standard, long-term use may pose a risk to human health. GB4806.3 has strict limit requirements for the migration of lead and cadmium in different types of equipment (flat products, hollow products, etc.).

3. Other physical and chemical indicators

According to the product's purpose and usage conditions, it may also be necessary to conduct tests related to pollution resistance, heat shock resistance, etc.

5、 Required documents for processing

Ceramic tea set samples (2-3 pieces/specification)

Product specification manual

Material composition description (glaze type, firing process, etc.)

Product images (overall and detailed)

Copy of Business License

Testing Application Form

6、 Precautions

Regarding the selection of glaze color technology

The risk of lead and cadmium leaching varies greatly among ceramic products with different glaze processes. The underglaze color process usually has a lower risk of lead and cadmium migration due to the complete coverage of the painted pattern by the glaze layer; The painted patterns of glaze painting technology are directly exposed on the outer surface, which poses a relatively high risk. Before conducting testing, the glaze process type of the product should be clearly labeled.

Regarding the Classification of Instrument Types

GB4806.3-2016 specifies different limit requirements for different types of utensils: flat products with a depth not exceeding 25mm have the strictest limit, followed by hollow products (pots, cups, cans, etc.), and large hollow products (such as large tea trays, tea seas) have relatively loose limit requirements. The testing conditions and result judgment standards for different types of equipment are different, and should be confirmed with the testing agency in advance.

Regarding multi material combination products

If ceramic tea sets contain metal components (such as metal pot lids and metal tea drain frames), they must also meet the requirements of GB4806.9-2016 "National Food Safety Standard for Metal Materials and Products in Contact with Food" and undergo additional metal material testing.

7、 Cost and cycle reference

|Project | Reference Scope

|Testing cycle | 5-7 working days

|Basic cost for a single specification | 800-1500 yuan

|Multi specification combination | Depending on specific quantity and material complexity

If the product needs to meet multiple GB4806 sub standards simultaneously (such as metal+ceramic combination), the cost will increase accordingly.

8、 Certificate validity period

The GB4806 test report does not have a fixed validity period, but the following situations require retesting:

Change in raw material supplier or formula

Production process adjustment

National standard updates and revisions

Customers or platforms have new requirements
