To better manage fulfillment center storage space, so that products are received and shipped to buyers more quickly, inventory storage limits can be applied. Storage limits are based on volume (measured in cubic feet) and are set for each storage type. Your current and potential storage limits and usage are shown when you expand Storage Volume, which you can view in your Inventory performance dashboard and Shipping Queue
Individual selling accounts have a set storage limit of 10 cubic feet; this value does not change. Individual selling accounts are not subject to storage limit increases.
Professional selling accounts may or may not have storage limits, depending on the following criteria:
Professional accounts that do have storage limits will still have a minimum of 25 cubic feet for standard, over-size, clothing, or footwear inventory.
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.
Storage limits are calculated using several factors including:
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.
Storage limits are applicable for six storage types: standard-size, oversize, apparel, footwear, flammable, and aerosol. To see which storage types your products are categorized as and how much cubic feet they occupy, go to FBA Inventory Age and the Inventory Age report.
If you do not see a storage type in your Storage Volume, it is because you have a limit of zero for that storage type.
Dangerous goods storage limit adjustments (flammable and aerosol) are handled separately from other storage types. See FBA Dangerous Goods program for more details.
Example: A unit measuring 47 x 12 x 10 inches divided by 1,728 = 3.3 cubic feet.
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 25 cubic feet and you have 26 cubic feet of standard-size inventory at an Amazon fulfillment center, you will not be able to create a new standard-size inventory shipment. However, if you are below your storage limit for oversize inventory, you will be able to create shipments of oversize inventory.
If you send more inventory than your storage limit allows, the extra inventory may be refused at the fulfillment center. For more information, see Shipping and routing requirements.
Storage overage fees will be charged if your existing inventory exceeds your storage limit for any storage type on any day within a given month. Please visit the Overage fee help page to learn more.
There are three ways to decrease the amount of inventory you have in an Amazon fulfillment center:
For more information, see Remove inventory (overview).
At this time, Amazon does not offer the ability to purchase storage space.
No. Storage types are determined by Amazon based on characteristics of a product.
You can check which storage type your products are categorized as and how much cubic feet they occupy on the FBA Inventory age page.
No. Inventory cannot be traded between storage types.
The storage type previously referred to as “hazmat” has been converted into two new storage types – aerosol and flammable. Storage limit adjustments for aerosol and flammable storage types are handled separately. See FBA dangerous goods (hazmat) program for more details.
Most sellers with Professional selling accounts have an IPI score, but some do not because we do not have enough data to generate a score for the account (for example, sellers who are new to FBA or have small quantities of FBA inventory).
After you first receive an IPI score, you will not be subject to storage limits for two full storage limit cycles.
You can view the date you received your first IPI score by clicking the Show details link 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.
Most sellers will receive their first IPI score approximately 15 weeks after their first product is received by FBA.
Visit the Inventory performance dashboard for recommendations on managing your inventory.
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 Storage Volume at the bottom of the Inventory performance dashboard. Please note that Selling Partner Support does not provide further guidance.
