FBA inventory storage limits

To better manage fulfillment center storage space so that products are received and delivered to buyers more quickly, inventory storage limits may be applied.

Storage limits are based on units and are set for each storage type. Your current limits, potential storage limits, and usage are shown when you expand Restock Limits, which you can view in your Inventory performance dashboard and Shipping Queue.

Individual selling accounts have a default storage limit of 250 units for standard-size items, 150 units for oversize items, and 25 units for Hazmat items, and are not subject to storage limit increases.

Professional selling accounts storage limits depend on the following criteria:

• Sellers who maintain an Inventory Performance Index (IPI) of the required threshold or above on the week before the next period limits are enforced receive higher storage limits.
• New sellers who have been active for less than 13 weeks, or sellers without enough sales data receive default storage limits of 250 units for standard-size items, 150 units for oversize items, and 25 units for Hazmat items.

Storage limits are updated quarterly and calculated using several factors including:

• Your sales volume, including your sales' seasonality periods
• Your historical IPI scores
• Available fulfillment center capacity

Sellers with consistently higher IPI scores will receive higher storage limits, adjusted for sales volume and available capacity. When setting limits for an upcoming quarter, Amazon considers both your recent sales volume and seasonal volume from the last year.

Professional account holders can track their Inventory Performance Index in the Inventory performance dashboard and learn about IPI on the IPI Help page. The dashboard provides a hub for optimizing your FBA business, including customized recommendations to grow your sales and reduce costs. Your IPI score is updated weekly based on your ongoing inventory management.

The green, yellow, and red indicators also alert you to how close you are to your limit:

Storage limits are applicable for three storage types: sortable, non-sortable and dangerous goods. To see which storage types your products are categorized as and how many units they occupy, go to FBA inventory age and the Inventory Age report. If you do not see a storage type in your Storage Monitor, it is because you have a limit of zero for that storage type.

Under the FBA inventory storage limits policy, you will not be able to create a new shipment to Amazon for a storage type until your inventory level drops below your limit for that storage type.

For example, if your current limit for standard-size inventory is 200 units and you have 220 units of standard-size inventory at an Amazon fulfillment center, you cannot create a new standard-size inventory shipment. However, if you are below your storage limit for oversize inventory, you can create shipments of oversize inventory.

If you send more inventory than what your storage limit allows, the extra inventory may be refused at the fulfillment center. For more information, go to Shipping and routing requirements.

There are three ways to decrease the amount of inventory you have in a fulfillment center:

• Sell more inventory. Manage Inventory Health provides recommendations to increase sales.
• Request to have inventory returned to you by creating a removal order.
• Request to have inventory disposed of by creating a removal order.

You can reduce your inventory levels by removing inventory from fulfillment centers. For more information, see Remove inventory (overview).

For recommendations on managing your inventory, go to the Inventory performance dashboard.

Can I buy more storage space?

No, storage space cannot be purchased.

Can I change the storage type of a product?

No. Storage types are determined by Amazon based on the characteristics of a product.

You can check which storage type your products are on the FBA inventory age page.

Can I trade space for one storage type with space in for another storage type?

No. Inventory cannot be traded between storage types.

What if I don't have an IPI score or am a new FBA seller?

Most sellers with Professional selling accounts have an IPI score, but some do not because we don’t have enough data to generate a score. This is usually the case for sellers who are new to FBA or have small quantities of FBA inventory.

You can view the date you received your first IPI score by clicking Show details under the IPI score color bar. This will reveal your Historical performance index, and your First IPI score date will be visible above the graph.

Will my FBA inventory storage limits change?

We continually assess our network capacity to find opportunities to increase storage limits. You can see your most up-to-date storage limits by expanding Restock Limits at the bottom of the Inventory performance dashboard. Please note that Selling Partner Support does not have further guidance to offer.

How do I get a storage limit increase for the next period?

Your storage limit is based on how well you drive sales and efficiently manage on-hand inventory as measured by your Inventory Performance Index (IPI) score. The best way to improve your IPI score, increase your storage limit, and minimize your FBA storage fees is to keep your inventory at lean levels while ensuring you have enough on-hand inventory to minimize lost sales of popular items.

To learn more about how you can improve future storage limit allocations , go to IPI frequently asked questions.

My IPI score has increased. Can my storage limits be reviewed immediately?

No. Your current storage limit remains in effect until the next adjustment cycle. We encourage you to take actions to maintain your IPI score in time for the next storage limit cycle.
