Amazon rejected the listing because at least one attribute value doesn't meet Amazon's expected format, range, or content rules. Amazon validates every attribute against the product type's spec — any mismatch fails the upload.
Why it happens
- Incorrect formats. Letters where numbers are expected (or vice versa).
- Unsupported characters. Special symbols Amazon doesn't allow.
- Out-of-range values. Numeric values beyond Amazon's accepted limits.
- Missing mandatory fields. Required attributes are empty.
- Typographical errors. Mistakes or inconsistencies in the values.
- Non-compliant data. Values that don't meet category-specific criteria.
How to fix it
- Open the product's template in the app and review the flagged attributes.
- Correct the format or value to match Amazon's spec for the product type.
- Re-upload the product after saving the corrections.
