Warning: FBA Inventory Intake Blocked by 2026 for Sellers Below 400 IPI!

Amazon FBA Inventory Management Policies Tighten: Alert for Sellers Below 400 IPI Score

Currently, Amazon's FBA (Fulfillment by Amazon) inventory management policies have been significantly strengthened. Sellers with an IPI (Inventory Performance Index) score below 400 face severe disruptions to their business operations due to inventory intake restrictions and increased costs. It's crucial to check your IPI score and improve inventory efficiency right away.

Key Changes in Amazon's Stricter FBA Inventory Management Policies

Currently, the importance of inventory management for Amazon FBA sellers is more critical than ever. Amazon continues to strengthen its inventory management policies to ensure efficient Fulfillment Center operations. Notably, the FBA Capacity Limits, recently implemented, have shifted from quarterly to monthly, demanding more agile inventory management. Furthermore, IPI score thresholds are being strictly enforced: if your score drops below 400, inventory intake can be immediately restricted. Adding to this, with Amazon's FBA Prep Services recently discontinued, sellers are now solely responsible for all product preparation and labeling, increasing overall operational burden. Failing to recognize and prepare for these changes can lead to unexpected cost increases and lost sales opportunities.

Key Policy Details

Maintaining an IPI Score of 400 is Essential Amazon measures IPI scores on a scale from 0 to 1,000, and maintaining 400 points or higher is the minimum requirement to avoid FBA inventory restrictions. If your score falls below 400, your inventory storage capacity will be limited.

4 Key Factors Determining Your IPI Score Your IPI score is updated weekly based on the following four metrics: Excess Inventory Percentage: Inventory exceeding 90 days of projected sales. Sell-Through Rate: The quantity of inventory sold over the past 90 days divided by the average quantity of inventory available. Stranded Inventory: Inventory in the fulfillment center that cannot be sold due to listing errors or other issues. In-Stock Rate: The percentage of time your sellable ASINs (Amazon Standard Identification Numbers) have been in stock over the past 30 days.

Monthly Inventory Limits Applied Based on Cubic Feet Currently, FBA inventory limits are recalculated monthly and applied based on volume (cubic feet), not the number of units. These limits are determined by comprehensively considering a seller's past sales volume, inventory utilization, and IPI score.

Stricter Aged Inventory Surcharge For inventory stored for 181 days or more, an additional Aged Inventory Surcharge is applied, on top of the Monthly Storage Fee. Notably, recently increased policies have raised the surcharge rates for inventory stored for 366 days or longer.

⚠️ Serious Consequences of Failing to Meet IPI Scores and Violating Policies

FBA Inventory Intake Restrictions and Refusals: You may be unable to send new inventory to Amazon fulfillment centers, leading to stockouts and lost sales opportunities, even for your best-selling products. Overage Fees: For inventory exceeding your allocated storage limits, additional overage fees will be charged on top of regular storage fees, significantly eroding your profitability. ASIN-Specific Restock Caps: Even if your overall account has sufficient storage capacity, restocking for specific ASINs may be restricted. Revenue Loss and Account Health Deterioration: Stockouts lead to decreased customer satisfaction and lower sales rankings, negatively impacting revenue in the long run, which can, in turn, create a vicious cycle of IPI score decline.

3 Actionable Plans You Can Implement Right Now

1. Check Your IPI Dashboard Weekly: Log in to Seller Central, navigate to the Inventory → Inventory Performance dashboard, and review your IPI score and detailed metrics every week. Pay close attention to Excess Inventory, Sell-Through Rate, Stranded Inventory, and In-Stock Rate. 2. Immediately Address Excess and Stranded Inventory: On the Inventory → Manage Inventory Health page, identify excess and stranded inventory. Quickly liquidate or resolve these issues by creating Removal Orders, offering price discounts, or running advertising campaigns. 3. Develop Strategies to Improve Sell-Through Rate: It's crucial to increase your sell-through rate to prevent inventory from sitting too long in Amazon warehouses. Boost your sales velocity through effective listing optimization, utilizing Amazon Ads, and implementing competitive pricing.

Common Mistakes to Avoid

Treating IPI as Just a "Backend" Metric: Many sellers mistakenly view their IPI score as merely a number and neglect to manage it regularly, only to react too late after receiving sudden inventory restriction notifications. Remember that IPI is a critical indicator for the growth of your Amazon FBA business. Focusing Solely on Bulk Shipments Over Inventory Turnover: Sending excessive inventory to Amazon warehouses without proper sales forecasting inevitably leads to excess inventory and a bomb of long-term storage fees. Currently, it is far more important to increase your inventory turnover through a small-batch replenishment strategy.
