Core Issue: Definition and Differences Between Test Reports and Certificates

A test report is a document issued by a laboratory after testing a sample in accordance with a standard, containing test items, methods, data and results. A certificate is usually a declaration or authorization of conformity issued by the manufacturer, authorized representative or certification body based on the test report and other technical documents, such as a CE Declaration of Conformity or an FCC Grant of Authorization.

The main difference: the report focuses on technical data and test results; the certificate focuses on compliance declaration or authorization. In e‑commerce platform reviews, both are often required to be submitted together and cannot be used interchangeably.

Applicable Scenarios: File Identification in Platform Compliance Review

On Amazon, TEMU, SHEIN, Walmart and other platforms, when reviewing a product listing or category approval, the platform may request test reports and/or certificates either together or selectively. For example:

  • Children’s toys listing: may requests a CPC and children’s product test report (issued by the manufacturer or importer) and a corresponding third‑party test report.
  • Electronic/electrical products: May require FCC SDoC or FCC ID certification (depending on device type), along with a test report demonstrating compliance.
  • Chemical products: May require applicable compliance or applicable compliance test reports; platforms generally do not require a certificate and accept the report as the submission document.

Specific requirements depend on the product listing page and product category. It is recommended to read the platform compliance guidance before preparation.

Common Misunderstandings: Confusion Between Test Reports and Certificates

Misconception 1: A test report is the same as a certificate and they are interchangeable. In fact, the test report is a technical document, while the certificate is a compliance declaration or authorization. Platform reviewers typically need to verify each separately. For example, a CPC and children’s product test report Use cautious wording such as may require, depends on product type, applicable regulation and conformity route. the manufacturer or importer based on a test report; providing only the test report cannot prove that the product meets children’s product safety requirements.

Misconception 2: The validity period of a certificate equals the validity period of its underlying test report. The validity of a certificate depends on regulatory requirements and product changes. For example, a CE Declaration of Conformity has no fixed validity period, but if the product design, standard or applicable regulation changes significantly, the technical file must be updated and the certificate re‑issued. Whether a test report can still be used depends on platform rules; the platform reserves the right to request a newer report.

Misconception 3: As long as a certificate issued by a certification body is available, no test report is needed. In reality, a certificate is usually based on a test report. The platform reviewer may request the test report to verify the scope of testing, methods used, and laboratory qualifications.

Document Preparation Suggestions: When a Report Is Needed vs. When a Certificate Is Needed

The following is general guidance. Actual requirements depend on product category, target market, and platform rules:

  • Children’s products (U.S. product safety authority jurisdiction): A CPC and children’s product test report (issued by the importer or manufacturer) and a children’s product test report from a third‑party laboratory are required.
  • Electronic/electrical products (U.S. FCC jurisdiction): For intentional radiators, an FCC ID grant of authorization (issued by an FCC‑recognized TCB) is generally required, along with a test report. For unintentional radiators, only SDoC may be needed, in which case no certificate is required but a test report is still needed.
  • Electronic/electrical products (EU CE jurisdiction): For low‑risk products, the manufacturer issues a CE Declaration of Conformity (self‑declaration), and a notified body certificate is not required. For high‑risk products (e.g., wireless devices, medical devices), a notified body may be involved, and a corresponding certificate is issued. In either case, a test report provides the technical support.
  • Chemical compliance (applicable compliance, applicable compliance): Platforms usually require test reports, not certificates. Some platforms may accept a supplier’s declaration of conformity as a supplement.

Recommendation: First confirm the specific documentation requirements for your product category on the platform, then determine whether a test report, a certificate, or both are needed.

Pre‑submission Checklist: Verify File Type and Content

  • Check whether the test report is issued by a qualified laboratory (e.g., ISO 17028 accredited), and whether the report includes sample description, test standard, test date and results.
  • Check whether the certificate (e.g., children product documentation, CE DoC, FCC ID grant) is issued by a legitimate entity (manufacturer, importer, or notified body), and whether the certificate information matches the report and product identification.
  • Confirm that the product models, colors, accessories, etc. covered by the report are consistent with the listed product. If there are differences, a statement of differences or additional testing may be needed.
  • Verify that the fields required by the platform upload page (e.g., standard name, validity period if any, certificate number) are completed accurately.

Platforms (including Amazon, TEMU, SHEIN, Walmart, TikTok Shop, etc.) retain the final decision on document review. Product category, target‑market regulations, product changes, and platform rules may affect the validity and acceptance of test reports and certificates. It is recommended to consult a professional testing and certification compliance review team or legal advisor before formal submission.
