Stranded Inventory
FBA units you own but cannot sell because the listing is suppressed, deactivated, or otherwise broken.
Stranded Inventory refers to FBA units that exist in Amazon's fulfillment centers under your account but are not currently sellable because the listing has a problem. Common causes: the listing was suppressed for a content violation, the ASIN was merged into another listing, the seller account is gated for the brand, the listing was accidentally deactivated, or the product was flagged for a category restriction.
Stranded inventory is a triple loss: you can't sell it (no revenue), you're paying storage fees on it (cost), and it counts against your IPI score (cap on future capacity). Amazon's Stranded Inventory page in Seller Central lists all stranded units with the reason and a recommended fix; the fix usually requires editing the listing, opening a case, or filing a removal order.
The playbook: check the Stranded Inventory page daily (yes, daily — small amounts pile up fast), fix what's fixable, file removal orders for the rest. SellerVault's daily inventory health check surfaces stranded inventory alongside other restock priorities so it doesn't get forgotten.
