Overview

On December 5 2023 Amazon expanded the FBA Manage Inventory Health Report for U.S. sellers by adding three data fields that surface recommended stock levels, replenishment quantities, and short‑term demand forecasts. The metrics are available both in the Seller Central interface and through the public GET /fba/inventory/v1/health API, giving sellers a data‑driven way to balance inventory, avoid stock‑outs, and curb excess storage fees.

Key Points

• Three new data points — The report now returns fba‑minimum‑inventory‑level, fba‑replenishment‑need, and fba‑forecasted‑demand for every SKU in the United States marketplace.
• API exposure — All three fields are included in the same health‑report endpoint, allowing third‑party tools, custom dashboards, and automated scripts to pull the numbers without manual export.
• Effective date — The enhancement launched on December 5 2023; any historical records generated before that date will not contain the new fields.
• Inventory‑planning focus — The metrics are engineered to help sellers set safety‑stock thresholds, schedule inbound shipments, and align inventory with projected sales velocity.
• U.S.‑only rollout — At present the change applies exclusively to the United States marketplace; Amazon has indicated that other regions will receive the update in later releases.
• No extra fees — Access to the new fields does not incur additional charges; they are part of the standard FBA health‑report package for eligible sellers.

How the New Metrics Work

1. fba‑minimum‑inventory‑level — Calculates the smallest quantity of a SKU that should remain in Amazon’s fulfillment network to satisfy expected demand while accounting for supplier lead time and a safety‑stock buffer.

   • Example: A vendor selling silicone kitchen spatulas imports the product from a factory in Vietnam with a 30‑day transit time. Amazon’s algorithm determines that 150 units represent the minimum safe stock, so the seller should never let the Amazon inventory dip below that number.
