Effective April 1, 2024, a low-inventory-level fee will apply to standard-size products with consistently low inventory relative to customer demand. When sellers carry low inventory relative to unit sales, it inhibits our ability to distribute products across our network, degrading delivery speed and increasing our shipping costs.
A low-inventory-level fee will only apply if a product’s inventory level relative to historical demand (known as “historical days of supply”) is below 28 days. We will only charge a low-inventory-level fee when both the long-term historical days of supply (last 90 days) and short-term historical days of supply (last 30 days) are below 28 days (4 weeks). For example, if a product’s short-term historical days of supply is above 28 days but long-term historical days of supply is below 28 days, the low-inventory-level fee won’t apply.
For each seller, we will calculate the historical days of supply metric at the parent-product level, and we will add the low-inventory-level fee to the FBA fulfillment fee for all shipped units of eligible products. Note that some products are not eligible for the low-inventory-level fee. For more information on fee eligibility, review the FAQ below.
