This article addresses error messages that one may encounter when listing FBA.

INVALID_MSKU_REMAP

This SKU already exists in your inventory and is mapped to a different ASIN. You will need to change the SKU for this item. It may be that the ASIN for the SKU has changed in the catalog.

This issue occurs when Amazon.com’s information is not in sync with the information provided by Amazon’s MWS API. This is outside of our control and usually remedies itself the next time Amazon initiates an API sync.

If you are still having this issue after 24 hours, contact Seller Central Support and tell them that the item is not being found when searched in their MWS API. They should provide a window for when the problem will be solved.

Not all products are eligible for Stickerless Commingled Inventory. Products in grocery, health and beauty, and media must always be labeled. Amazon is always evaluating categories and products and may change product eligibility at any time.

Solution (possible): Add the item to the FBA Shipment in Seller Central. After adding the item, some version of the following message may appear: This product is not eligible for stickerless commingling. This product requires labeling to be received at our fulfillment centers. I agree to apply labels to these products.

Item has no eligible Fulfillment Center because it is hazmat (hazardous material). You cannot send it to FBA.

Unfortunately, Amazon does not tell us which item is causing the error.

UPC for the listing was assigned to multiple ASINs. When you send the shipment, the ASINs conflict in the back end and cause errors in the system. This can happen when an item that used to be stickerless now becomes requiring label.

Solution: You may have to create a new listing on Seller Central.
