Error!

You cannot change a product detail page, or add offers on another seller’s generic product, or copy the product detail page to another store. If you want to sell a generic product, you must create a new product. To create a new product, follow the process outlined in Add a Product tool. For more information, go to Amazon Generic Product Policy. If you believe that you are compliant with our policy, contact Selling Partner Support and mention error code 5885. When you contact Selling Partner Support, provide the following information: • Product title • SKU • ASIN • If you are using an inventory file template for feeds upload, provide the Batch ID of the processing report. • Real world image of the product and packaging that clearly shows if the product is generic and unbranded.
