Amazon FBA Storage Capacity Limits help control how much inventory sellers can store and send to Amazon fulfillment centers. These limits are designed to ensure warehouse space is used efficiently while maintaining fast receiving and fulfillment times.
Understanding how storage capacity works can help sellers avoid shipment delays, inventory restrictions, and inbound shipment errors.
📦 What Are FBA Storage Capacity Limits?
Storage capacity limits determine the maximum amount of inventory you can store or send to Amazon within a specific storage type.
Amazon measures capacity using:
Cubic feet (storage usage)
Shipment volume limits
Inventory performance metrics
If you exceed your available capacity, Amazon may prevent you from creating new shipments until additional capacity becomes available.
🏷️ Types of Storage Capacity
Amazon separates inventory into different storage types, including:
Sortable
Items typically stored on shelves, such as:
Books
DVDs
Video games
Toys
Small electronics
Non-Sortable
Larger items that cannot fit on standard shelving.
Oversize
Large and bulky products requiring special storage.
Apparel
Clothing and textile products.
Each storage type has its own capacity allocation and limits.
📊 How Amazon Determines Capacity
Amazon considers several factors when assigning storage capacity:
Inventory Performance Index (IPI)
Historical sales volume
Sell-through rate
Inventory age
Available warehouse space
Seasonal demand
Sellers with strong inventory performance often receive higher capacity allocations.
🚚 How Storage Capacity Affects Shipments
Storage capacity impacts your ability to:
Create inbound shipments
Send additional inventory
Replenish stock
Expand inventory levels
If your shipment exceeds available capacity, Amazon may display errors such as:
This product exceeds the allowed volume for SORTABLE storage.
or
Shipment exceeds available capacity.
🔍 How to Check Your Capacity
In Seller Central, you can review your available capacity through:
Inventory Performance Dashboard
and
Storage Volume Monitor
These tools show:
Current storage usage
Maximum allowed capacity
Available shipment volume
Capacity utilization percentages
⚠️ Common Reasons Capacity Is Reached
Sellers often hit capacity limits because of:
Slow-moving inventory
Excess inventory storage
Large inbound shipments
Seasonal storage restrictions
Lower IPI scores
💡 Tips for Managing Capacity
To maximize available capacity:
Remove aged inventory
Improve sell-through rates
Avoid overstocking slow sellers
Monitor storage usage regularly
Create smaller replenishment shipments
Keep your Inventory Performance Index healthy
❓ What Happens If You Reach Your Capacity Limit?
If your account reaches its storage limit:
New shipments may be blocked
Shipment creation may fail
Certain products may be restricted from inbound shipment
You may need to wait for inventory to sell or remove inventory
In most cases, you can keep your existing inventory and shipment batches while waiting for additional capacity to become available.
✅ Summary
Amazon FBA Storage Capacity Limits control how much inventory sellers can store and send to fulfillment centers. Monitoring your capacity and maintaining healthy inventory performance can help prevent shipment delays and storage restrictions.
