Overview

Even when your inventory is physically sitting in Amazon's fulfillment centers, it doesn't always mean customers can buy it. Amazon refers to this as a "buyability" issue, and it can quietly eat into your sales if left unaddressed. Understanding the common reasons inventory becomes unbuyable — and knowing where to check — is essential for maintaining healthy FBA operations.

Key Points / What Sellers Need to Know

• Non-buyable status is the most common cause — The majority of buyability problems stem from inventory being classified under a non-buyable status such as stranded, reserved, researched, or unfulfillable.
• Stranded inventory is tied to listing issues — When inventory sits in fulfillment centers without an active product offer, it becomes stranded and invisible to shoppers.
• Reserved inventory is typically temporary — Units set aside for order fulfillment, processing, or investigations are usually restored automatically.
• Unfulfillable inventory cannot be sold — Expired or damaged goods must be removed or disposed of through a removal order.
• Search suppression can also block sales — Even buyable inventory may not reach customers if listings are suppressed due to quality issues.
• Low inventory with low sales velocity creates regional gaps — Amazon may limit availability in certain areas when stock is scarce and demand is minimal.

Understanding the Four Non-Buyable Inventory Statuses

Amazon categorizes non-buyable inventory into four main statuses, all visible through the FBA Inventory overview page. Stranded inventory occurs when products in the warehouse lack an active listing, typically because of listing errors or account health problems. Reserved inventory is temporarily held to fulfill pending orders or for internal processing and investigations — this status usually resolves on its own without seller intervention. Researched inventory is under Amazon's investigation, often related to lost or damaged unit claims, and can take up to 60 days to resolve, though most cases are completed much sooner. includes items in unsellable condition, such as expired or damaged products, which sellers must remove or have disposed of.
