When stainless steel thermos are sold in the US market, they need to comply with the food contact material safety standards of the US Food and Drug Administration (FDA). The following are the detailed steps and key points for stainless steel thermos to undergo FDA food contact material testing:

1. Determine the testing standards

According to FDA regulations, stainless steel thermos need to comply with relevant standards and regulations. These standards and regulations may involve aspects such as material safety, chemical composition, and physical properties. Specific standards include:

- 21 CFR 175.300: General requirements for metal materials.

- GRAS (Generally Recognized As Safe): Applicable to total chromium testing of stainless steel materials.

2. Choose the right testing method

For the inner and outer double-layer stainless steel materials of stainless steel thermos, the possible testing methods include:

- Chemical composition analysis: Detect whether the raw materials of the thermos contain harmful chemical components banned by the FDA.

- Migration test: Evaluate whether the chemical components in the surface coating or material of the thermos will migrate into the food when it comes into contact with food.

- Toxicity assessment: Toxicity assessment of chemical components detected in migration test to determine whether they will cause harm to human health.

3. Prepare samples

Prepare sufficient and qualified samples according to the requirements of the test method. Make sure that the samples are not processed in any way to reflect the true situation of the product.

4. Submit test application

Submit the samples and test application to the FDA-approved testing agency. The application should include detailed information of the product, the purpose of the test, the applicable standards, etc.

5. Conduct the test

The testing agency will test the samples according to the submitted test application and the applicable standards. This may include:

- Chemical analysis: Pay attention to whether the raw materials and coatings of the thermos contain harmful chemical components.

- Physical property test: Evaluate the thermal insulation performance, compressive strength and other physical properties of the thermos.

- Toxicological evaluation: Determine whether the migrated chemical components are harmful to human health.

6. Obtain the test report

The testing agency will issue a detailed test report stating the test results of the sample and whether it complies with the relevant standards and regulations of the FDA.

7. Compliance determination

Based on the results of the test report, determine whether the thermos bottle meets the FDA's food contact material safety standards.

8. Registration and filing

Although the FDA itself does not conduct any testing, the product needs to be registered and filed on the FDA official website. This includes:

- FDA registration: The product needs to be registered on the FDA official website to obtain the qualification for legal sales.

- FDA testing: Testing is carried out according to the regulations published by the FDA to ensure that the product complies with FDA regulations.

9. Continuous compliance

Ensure that the product continues to comply with FDA standards during production, transportation and use. Regular product testing is performed to ensure product safety and compliance.

Through the above steps, you can ensure that the stainless steel thermos bottle meets the US FDA's food contact material safety standards, thereby ensuring the food safety of consumers.
