Priority Documents to Check When Files Are Incomplete

When a platform review returns a message that documents are incomplete, it is not always necessary to resubmit all files immediately. It is recommended to first compare against the platform rules and focus on checking the following four categories: business qualification documents, product technical documents (including test reports and declarations of conformity), labels/instructions/packaging images, and the scope of existing compliance documents. Requirements may vary by product category (e.g., electronics, children’s products, cosmetics, toys); the final basis is the platform’s published document submission requirements and applicable regulations.

Business Qualification Documents

Business qualification documents typically include: business license (check that the business scope covers manufacturing or sales of the relevant product), import/export operation certificate (if cross-border trade), production license (if applicable), and manufacturer or brand authorization letter (if acting as agent or OEM). Verify that the documents are within their validity period and that the company name matches the entity registered on the platform. For overseas platforms (e.g., Amazon, TEMU, Walmart, etc.), a corresponding local business registration number or tax information may be requested. It is recommended to keep original scanned copies and ensure they are clear and legible.

Product Technical Documents

Product technical documents are central to platform compliance verification. Common documents include:

  • Test reports demonstrating compliance with applicable safety standards or directives (e.g., FCC, CE, UKCA, RoHS, REACH, CPC document, etc., depending on target market and product category);
  • Declaration of Conformity (DoC or Declaration of Conformity), signed by the manufacturer or its authorized representative;
  • Product description, technical specifications, circuit diagrams, or bill of materials (BOM) (may be required by some platforms).

Note: The test report number (Report No.) is primarily used to locate the report version and match uploaded files; it cannot be used alone as proof of authenticity. For further verification, contact the issuing laboratory or use the platform’s designated verification channel.

Labels, Instructions and Packaging Images

Some platforms require product labels, warning statements, instruction manuals, or color packaging images. Label content must include necessary regulatory information such as CE marking, country of origin, manufacturer name and address, model number, batch number, and warning statements (if applicable). Instructions must be in the required language of the target market (e.g., English, French, German). Images must be clear, unobstructed, and consistent with the information in the submitted qualification documents. Common deficiencies include: missing importer information on the label, instructions not translated into the local language, or packaging images showing a different model number than that in the test report.

Reusing Existing Test Reports and Compliance Documents

If you already hold test reports from other platforms or past projects, you may try to use them for the current platform review, but each item should be checked:

  • Is the product model and specification completely identical?
  • Are the applicable regulations or standard versions still accepted?
  • Is the report issuance date within the validity period (validity depends on regulations and platform rules and cannot be generalized)?
  • Does the report cover all test items required by the platform (e.g., children’s products may require CPC document + third-party testing; FCC certification may also require an authorization letter)?

Note: Different platforms have different acceptance policies for reports. It is recommended to consult the platform’s specific requirements regarding report validity and scope.

Common Scenarios Where Platforms Reject Files as Incomplete

Based on experience, the following situations are commonly flagged as incomplete:

  • Model number in test report does not match product label;
  • Declaration of Conformity lacks signature or stamp;
  • SDS/MSDS not prepared in accordance with REACH or local regulatory format;
  • CPC document certificate does not include manufacturer information or the testing laboratory is not CPSC or applicable product safety authorities or market surveillance authorities-recognized;
  • Images are blurry, incomplete, or have been edited;
  • Submitted file language does not meet platform requirements (e.g., only Chinese provided instead of the local official language).

When you receive a rejection notice, it is recommended to identify the problem directly based on the platform feedback to avoid blind resubmission.

Pre-Submission Checklist

Before resubmitting, it is recommended to confirm each step as follows:

  1. Are all file names clearly identifying the product name, model, and file type?
  2. Do file formats meet platform requirements (PDF, JPG, etc.) and size limits?
  3. Is information consistent across files (model, brand, manufacturer name, address, etc.)?
  4. Are signatures, dates, and stamps complete and valid?
  5. If translations are provided, are they accurate and reviewed by a professional organization?
  6. Keep original versions and submission records of all files for future verification.

The final review outcome is subject to platform rules and the actual content of submitted documents. This checklist is provided as a reference for document preparation only and does not constitute a guarantee of platform acceptance.

Risk Notice: The document verification approach described in this article is based on common scenarios and does not cover all platform and regulatory requirements. Product category, target market, regulatory updates, and platform review policies may affect conclusions. Always refer to the platform’s official document submission requirements and the latest compliance guidance. For matters involving CE/UKCA, FCC, FDA, CPSC or applicable product safety authorities or market surveillance authorities, REACH, RoHS, SDS/MSDS, etc., it is recommended to consult a qualified testing and certification organization for case-by-case evaluation.
