Conclusion: RSL (Restricted Substances List) is a chemical substance restriction requirement set by brands or retailers, and platforms such as Amazon conduct random inspections. The absence of a report may result in listing removal. The RSL report turnaround time is 5–10 working days, with a reference cost range of 1,000–5,000 RMB. The Shuwang Testing and Certification Platform can organize testing and issue reports based on the RSL documents provided by the client.
In 2026, Amazon will increase the frequency of RSL audits for textile, toy, and electronic accessory categories, and reports must cover all homogeneous materials. It is recommended to prepare in advance and ensure that the report remains within its one-year validity period.
