FBA inventory storage limits

To better manage fulfillment center storage space, we established inventory limits: 500 for small/standard-size and 100 for oversize inventory units, and 100 for hazmat items for all FBA sellers.

If you are subject to a storage limit, a storage monitor will appear in several places in your seller account, including your Shipping Queue. If you are not subject to a storage limit, the storage monitor will not be displayed. Alternatively, we may email you your storage limit from time to time.

You can remove or dispose off inventory at any time by submitting a removal order. See Remove inventory (overview).

Standard-size versus oversize

A standard-sized item is one that, when fully packaged, weighs 12 kg or less and does not exceed:

45cm on its longest side
34cm on its median side
26cm on its shortest side

Any item exceeding these dimensions is considered oversized.

To determine which of your products are standard-size and which are oversize, see Product size tiers.

Tracking your limit

Typically, inventory storage limits apply to new sellers and experienced sellers with slower-moving inventory. 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.

Storage limits are automatically evaluated every month to determine whether or not your limit should be adjusted. Your current inventory level takes into account your inventory in Amazon fulfillment centers, and any processed removal orders.

Note: It may take up to 24 hours for your inventory level to be updated once a shipment is received at an Amazon fulfillment center.

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

Green	Your inventory level is at less than 75% of your limit.
Yellow	Your inventory level is between 75% and 90% of your limit.
Red	Your inventory level is at more than 90% of your limit.

Exceeding your limit

You will be notified in your seller account and by email when you reach your inventory storage limit. You will not be able to create a new shipment until your inventory level drops below your limit. For ASIN-specific limits, you will not be able to add those ASINs to a new shipment until your inventory of that ASIN drops below your limit.

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.

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

Sell some of your current inventory
Request to have some of your inventory returned to you by creating a removal order
Request to have some of your inventory disposed of by creating a removal order

Important: Customer returns contribute to your overall inventory count.

When you submit a removal order or make similar changes, the inventory storage monitor won't reflect the changes until your request has been processed, which typically happens on the following day.
