Stranded inventory is FBA inventory in fulfilment centres that does not have an associated active offer, and, as a result, is not available for sale on Amazon.
If you add a product with stranded inventory to your shipment, you will receive a stranded inventory alert.
Amazon notifies you about stranded inventory in three ways:
When you delete or close a listing or change it from Fulfilled by Amazon to Fulfilled by Merchant, it may strand your inventory. Product listing issues, infringement concerns, or system errors can also result in stranded inventory.
For the complete list of explanations for stranded inventory, please see Resolve stranded inventory issues.
If there is lost inventory at the fulfilment centre, or if there are customer returns of an item without an active offer, this inventory will be stranded.
If the quantity column is populated on Bulk upload template (e.g. Inventory Loader), listings will automatically change from Fulfilled by Amazon to Fulfilled by Merchant which will strand your inventory.
Additionally, if you do not fill out the Is this product a battery or does it require batteries? column, it may strand your inventory in some categories.
When you create a new or revise an existing listing, make sure that the ASIN, SKU, and condition are the same as the inventory in your stranded inventory list.
Include all vital information for a listing before sending a shipment, including the brand, category, price, and condition.
