To better manage fulfilment centre 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 on the Storage Monitor display, 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 customised 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 set by volume. Your remaining 2020 storage limits will be determined based on your IPI during two score check weeks: the week of July 27, 2020 (Week 31) and the week of August 24, 2020 (Week 35). You are not subject to storage volume limits if your Inventory Performance Index is 500 or above on either one of these score check weeks.
Storage limits are applicable for four storage types: standard-size, oversize, clothing, and footwear. You can see which storage types your products are categorized as and how much cubic feet they occupy using the FBA Inventory Age page 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.
Dangerous goods storage limit adjustments (flammable and aerosol) are handled separately from other storage types. For more information, search for 'dangerous goods' in Seller Central and select Dangerous Goods FAQ at the top of the search panel.
Example: A unit measuring 100 x 60 x 25 cm divided by 28316.8 = 5.30 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 fulfilment centre, 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 fulfilment centre. 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 that you have in an Amazon fulfilment centre:
For more information, see Remove inventory (overview).
We may also create storage limits for specific ASINs. If an ASIN-specific limit is applied to your seller account, you can find the details in the downloadable Inventory Health report under the header asin-limit. This information is not available in the online Inventory Health report. See ASIN quantity limits for FBA.
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.
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 colour 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.
