Document Preparation Characteristics for Multi-Model Products

When submitting compliance documents for multi-model products (e.g., a series of electronic devices, toys, or apparel differing in color, size, or configuration), filling in the model field is especially important. During platform review, product names, model numbers, labels, reports, and instructions are typically cross-checked; any inconsistency may cause delays or rejection. This article is intended for sellers planning to list multi-model products on platforms such as Amazon, TEMU, and Walmart, to help organize document preparation with field considerations.

Model Consistency in Enterprise Documents

If enterprise documents (e.g., business licenses, manufacturer declarations, ISO certificates) mention product scope, the model expression should match subsequent product documents. For example, the model range listed in a manufacturer declaration should cover the models actually sold. Inconsistent abbreviations or omitted suffixes should be avoided. If the enterprise documents do not explicitly list specific models, it is recommended to attach a model list as an annex.

Requirements for Model Field in Product Documents

The model field in product documents (e.g., test reports, CPC document certificates, DoC) must be complete and accurate. For multi-model products, common practices include:

  • If differences are only in appearance or non-safety-related components, the models may be listed as a series in the report, provided core parameters (e.g., material, electrical structure) are identical.
  • If differences involve critical safety or performance parameters, each model may require a separate report or a supplemental difference statement.
  • Model strings should use alphanumeric characters, avoid special symbols, and exactly match the model entered in the platform seller center.

For example, a toy series includes models A-100, A-101, and A-102. If the report only tested A-100 but claims coverage of all models, supporting evidence (e.g., a difference declaration) must be provided; otherwise, the platform may request additional test data for other models.

Model Correspondence in Labels, Instructions, and Images

The model marked on product labels, instructions, packaging images, and product images uploaded to the platform must match the model string in the report. Common issues include:

  • Label shows “Model: A-100” but report states “A100” (hyphen missing).
  • Model on instruction cover does not match report model.
  • Model on uploaded product images is obscured or not shown.

It is recommended to directly reference the complete model string from the report when creating labels and instructions, and check consistency across all documents.

Adapting Existing Reports for Multi-Model Products

If an existing report covers only one model and you wish to use it for other models, evaluate the following:

  • Whether the other models fall within the coverage scope stated in the original report (e.g., the report explicitly lists a series of models).
  • If not covered, you may attempt to issue a difference declaration or supplemental testing. However, platform acceptance of a difference declaration depends on platform rules and product risk level.
  • Report validity (if any) must still comply with regulations and platform requirements. This article does not constitute a fixed validity determination; the final decision depends on product changes and platform rules.

Common Missing Document Issues

  • Model field incomplete — only lists “series product” without specific models.
  • Model on label inconsistent with report, e.g., extra prefix or suffix.
  • Lack of difference declaration document; platform cannot determine coverage logic.
  • After rejection, failure to carefully check field errors and resubmitting the same materials.

Pre-Submission Check Recommendations

  • Compile a list of all product models and cross-check against reports, labels, instructions, and seller center information item by item.
  • Ensure the model string in the report exactly matches labels, packaging, and images (including case, hyphens, spaces).
  • For series models, prepare a clear model difference statement with supporting evidence of coverage.
  • Retain all original test reports and registration documents to quickly provide them if the platform requests supplementary information.

Risk Notice

The content in this article is for reference only for document preparation and risk checking; it does not constitute a guarantee of platform acceptance. Platform review results are subject to platform rules, product documentation, and actual submitted content. Requirements may vary depending on product category, target market, and applicable regulations. It is recommended to assess based on specific circumstances.
