Table of Contents
In the past few years, Amazon has gradually made inventory storage update. Firstly, in the summer of 2020, FBA sellers faced a new limitation, making it difficult to launch new products on Amazon. This limitation was the ASIN-level quantity that was limited to just 200 units. Amazon implemented a new change after that. In April 2021, the ASIN-level limitation was removed, and Amazon introduced storage-type level inventory limitations. The available inventory storage space is six different storage types: apparel, aerosol, footwear, flammable, oversize, standard-size Recently, from the first of January 2022, Amazon’s IPI (Inventory Performance Index) threshold for storage limits becomes 400 (previously 500). Although as a part of its strategy, Amazon expands its storage capacity. The main intention of this restriction is to prevent large shipments during the holiday season because it consumes storage space.

What is Amazon Inventory Storage Limit?

 Amazon storage limits are based on volume and measured in cubic feet and represent the total amount of inventory you can store in Amazon fulfillment centers. These inventory storage limits are applied to manage fulfillment center storage space better.

In this way, the shipment of the products will be faster, and buyers will receive them quickly. When you expand Storage Volume, your current and potential storage limits and usage are shown. The information is available in your Inventory Performance Dashboard and Shipping Queue.

  • Individual selling accounts:

They have a set storage limit of 10 cubic feet, and this value does not change. Individual selling accounts are not subject to storage limit increases.

  • Professional selling accounts:

Depending on the following criteria, they may or may not have below storage limits:

  1. Sellers will not be subject to storage volume limits for standard-size, clothing, oversize, and footwear items if they maintain an Inventory Performance Index (IPI) of the required threshold or above on either of two score checkpoints.
  2. Sellers will not receive storage limits if they are new sellers who have been active for less than 26 weeks or sellers without enough sales data to generate an IPI score during both of the two score check weeks.
  3. The Professional accounts that do have storage limits will still have a minimum of 25 cubic feet for clothing, oversize, standard, or footwear inventory.

Actually, Restock Limits decide how many units of your Amazon FBA inventory you are allowed to send to fulfillment centers. They are set up per storage type.

Restock limits are apart from your Inventory Performance Index (IPI) and are applied independently. They’re determined based on your past and forecasted sales. If your IPI score is above 500, you will not have an additional storage limit on top of the restock limit.

  2. Secondly, go through “Inventory Performance.” After that tab and scroll down to click on your “Restock Limit” and find your “Utilization Quantity” and “Restock Limit,” which is known as “Maximum Inventory Level”.

How Can I Increase My Amazon Storage?

At the moment, and because of the FBA Inventory Storage policy, you are not allowed to create a new shipment to Amazon for a storage type until your inventory level drops below your limit for that storage type.

Here we mention an example. When 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 cannot create a new standard-size inventory shipment.

Additionally, if your oversize inventory is below your storage limit, you can create shipments of oversize inventory. Your extra inventory may be refused at the Amazon fulfillment center if you send more inventory than what the storage limit allows you.

All Sellers must meet the threshold score that Amazon sets. In case of falling below that threshold, Amazon will set storage limits on your account. This limitation is until you can improve your inventory health. At the time of writing, the average Amazon IPI ranges from 400 to 800.  

The average Amazon IPI ranges from 400 to 800.

Ideally, you should have at least a 550 score. Although a 400 to 549 score is still reasonable, it requires attention not to fall below the threshold. Your IPI storage will generally limit if your score incurs below 350. Besides, you have to pay overage fees.

Don’t forget to keep an eye on the IPI threshold on the Amazon website because of often changes.

Every three months, Amazon calculates your IPI:

  • 6 weeks before the quarter ends
  • At the end of each quarter

Therefore, before imposing inventory limits, Amazon notifies you and gives you enough time to improve your score.

You will qualify for unlimited storage space for each of six storage types if you score above the threshold during these two score check weeks.
