Inventory Performance Index threshold change and increased to 500.
Amazon is working to manage inventory performance to ensure all products have space available during peak. To enable this, Amazon is changing the IPI minimum threshold requirement to 500. Sellers below 500 will be subject to limits effective August 16, 2020 through the end of the year.
The majority of sellers will not be impacted by this change. Most sellers with IPI scores below 500 will have more storage space than last year.
You can improve your IPI by following guidance on improving sell through or reducing your excess and stranded inventory in the Inventory Performance Dashboard.
