Error 8004

The Product with SKU [%s] may be identical to existing ASINs ([%s]) based on these attributes: [%s]. For details, see

This error occurs when the product data you provided closely resembles the existing product data for one or more products in the Amazon catalogue. The error message specifies the similar products by providing an ASIN and the similar item attributes.

Whenever possible, Amazon presents customers with a single page for a product, regardless of how many sellers offer the product. Therefore, you must provide enough product data for Amazon to determine if your product matches an existing product or if it is a new, unique product.

Follow these steps to resolve this error:

  1. Search Amazon using the ASINs as listed in the error message to determine if the products are the same as your product.
  2. If you find a match, modify your product data to more closely resemble the existing product data. Carefully review the product title, UPC, brand, manufacturer, and manufacturer part number.
  3. If you do not find a match, modify your product data to more clearly differentiate your product. Carefully review the product attributes mentioned in the error message.
  4. Resubmit your modified product data.
