This error is commonly referred to as a “single matching error” and occurs when your Product ID (such as UPC, EAN, JAN, ISBN) corresponds to the Product ID of an existing ASIN, that means some of the information you’re submitting contradicts the product information (such as, title, brand, colour, size) that is already present for that particular ASIN.
"The provided SKU [SKU] conflicts with the Amazon catalogue. The standard product ID value(s) provided for this SKU corresponds to the ASIN [ASIN]; however, some information is in conflict with the Amazon catalogue. The conflicting attribute values(s) are Brand (Merchant: [MERCHANT_VALUE] / Amazon: [AMAZON_VALUE]). If your product is this ASIN, modify these attributes to reflect Amazon catalogue values. If your product is different from this ASIN, check if the standard product ID value(s) are correct."
This matching error occurred because we found a similar product in the Amazon catalogue. However, there is a discrepancy between some of the information you have submitted versus what is on Amazon. Hence, you must check if the product found is the same as the one you are trying to list.
