Temu Platform Requirements for RSL-PFAS Testing Items and Handling Process:

Temu platform's requirements for RSL-PFAS testing primarily focus on per- and polyfluoroalkyl substances (PFAS) in products and their migration behavior. The specific testing points are as follows:

I. Testing Item Classification

Per- and Polyfluoroalkyl Substances (PFAS) Residue Testing

For textiles and apparel (e.g., water/oil repellent treated materials), testing for PFAS residue after skin contact or washing, according to standards such as EN 17681.

Food contact materials (e.g., tableware, packaging containers) require testing for the potential migration of PFAS into food, referencing standards such as EPA 533 and FDA 176.170.

Per- and Polyfluoroalkyl Substances (PFAS) Migration Testing

• Simulate product usage scenarios (e.g., washing, high-temperature environments) to test PFAS migration, such as the migration of oil-resistant layers in packaging materials into food (must comply with FDA 21 CFR 175.300).

Per- and Polyfluoroalkyl Substances (PFAS) Composition Analysis

• Use techniques such as gas chromatography-mass spectrometry (GC-MS) to detect the types and content of PFAS in electronic and electrical products (e.g., waterproof coatings, seals) and industrial products (e.g., coatings, firefighting foam).

II. Key Testing Standards

Textile Products: Must pass EN 17681 standard testing to ensure residue levels are below safety limits.

Packaging Materials: Must comply with regulations such as EPA 533 (total fluorine content) and FDA 21 CFR 175.300 (migration levels).

Electronic and Electrical Products: Use GC-MS to analyze material composition and detect whether PFAS additives are present.

III. Other Related Requirements

Testing Agency Qualifications: Must possess relevant testing qualifications, and testing items must cover major PFAS substances such as perfluorocarboxylic acids (e.g., PFBA, PFOS) and perfluorosulfonic acids.

Sample Types: Include environmental samples (water/soil/air), biological samples (human/animal tissues), and industrial product samples.

IV. Handling Process

Select a Testing Agency

Engage a third-party testing agency with CNAS or ILAC certification to ensure the authority of test results.

Submit an Application

Fill out the product information form, providing detailed information such as product name, material, purpose, and production process.

Sample Shipping

Ship representative samples as required, ensuring the samples reflect the quality of the entire batch.

Testing and Analysis

The testing agency uses professional instruments such as GC-MS for composition analysis to determine the types and content of PFAS.

Report Issuance

After testing is completed, the testing agency will issue an RSL-PFAS test report.

Platform Review

Submit the test report and certification materials to the Temu platform for review. Once approved, the product can be listed for sale.

V. Risk Control Recommendations

Prioritize the use of PFAS-free or low-PFAS alternative materials;

Strengthen production process management to reduce the risk of PFAS contamination;

Conduct regular product testing to ensure compliance with platform requirements.

The above testing requirements reflect a comprehensive consideration of the potential health and environmental risks of PFAS. It is recommended that relevant companies plan testing solutions in advance and establish a compliance system.
