Why Is My FBA Inventory Stranded? How to Fix It

Stranded inventory is FBA stock sitting in a fulfillment center with no active offer attached to it. The units are real, the monthly storage fee is real, and the listing sells nothing. So if you are asking why is my FBA inventory stranded, the answer is almost always that the offer broke, not that the units moved.

This is the part that catches people out: Amazon keeps charging storage on stranded units, and it keeps a clock running on them.

What stranded FBA inventory means

Two things have to be true for a unit to sell through FBA: the unit has to be in the warehouse, and an active FBA offer has to point at it. Stranded inventory is the second half failing. The stock shows up in your inventory reports, it counts against your storage bill, and it is not buyable.

You are told about it in three places: an email, the Fix stranded inventory page, and the stranded inventory notification on your Inventory dashboard.

Why your FBA inventory went stranded

The common causes, in rough order of how often sellers hit them:

1. The listing was closed or deleted. The units stay in the warehouse and lose the offer.
2. The listing was switched from Fulfilled by Amazon to Fulfilled by Merchant. The fulfillment channel no longer matches the stock.
3. The SKU on the inventory and the SKU on the listing stopped matching, so the FNSKU has nothing to attach to.
4. A listing error, a compliance hold or an infringement claim took the offer down while the units stayed put.
5. A platform side error. Sellers reported a sitewide wave of listing errors stranding inventory across unrelated brands, which is worth checking before you rebuild anything.

How to fix stranded inventory step by step

Work in this order. The cheap fixes take minutes, so do not open a case first.

1. Open Fix stranded inventory in Seller Central and read the stranded reason on each row. The reason decides the fix.
2. If the reason is a closed or deleted listing, relist it. Amazon's automatic relist covers the reasons Listing closed, Listing closed and inventory error, and Item discontinued.
3. If the reason is Merchant fulfilled, change the fulfillment channel back to FBA. Automatic change to FBA does exactly this.
4. Once Amazon approves the offer, the units become buyable for customers within 24 hours.
5. If the SKU on the stranded row does not match the SKU on your listing, rebuild the listing on the SKU that the inventory carries. A new SKU will not pick up units that were received under the old one.
6. Only then open a case, and ask for the listing to be reconnected to the FBA inventory rather than for the stock to be moved.

What other sellers report, and what Amazon does not document, is that nudging the price by a cent can push a stuck offer back to active within minutes. Treat that as a workaround, not the procedure.

The automatic action that can remove your units

This is the expensive part, and almost nobody checks it.

Since June 30, 2020, aged stranded inventory is no longer classed as unsellable. Instead Amazon acts on it automatically, based on settings you control under Edit automatic-action settings on Fix stranded inventory. You choose how long a unit is allowed to sit stranded, up to 30 days, before the action fires.

Sellers on the forums report that the action can be set to dispose of units rather than return them, and that they only found out after the fact. Amazon's own announcement says removal happens "based on seller-configured settings" and does not publish a default, so go and read yours.

The order of events matters here. A disposed unit is gone, and a unit that is gone is not a unit you can relist, sell or claim.

How to stop it coming back

• Never delete a listing that still has FBA stock behind it. Close the offer if you have to, then relist, but do not remove the record.
• Before you flip a SKU to merchant fulfilled, check whether units for that SKU are still in a fulfillment center.
• Set your automatic-action window deliberately, and set it to return rather than dispose unless you genuinely want the stock destroyed.
• Check Fix stranded inventory on a schedule, not when the bill arrives. Stranded units pay the same monthly storage rate as everything else in Q4, and Q4 is when that rate is at its highest.
• Keep SKUs stable. Most stranding that is not caused by Amazon is caused by someone editing a SKU.

Stranded inventory is one of several clocks that run on FBA stock without asking you. The others are covered in our guide to the five clocks in FBA inventory management, and the related case where units arrive but never get credited to you is covered in what to do when an FBA shipment is delivered but not checked in.
