What happened?
Amazon US will introduce a Business Hour Delivery Rate requirement for seller-fulfilled orders for Amazon Business customers from September 30, 2026. Relevant sellers must maintain a rate of at least 90%. The metric is calculated over a rolling 14-day period and measures whether packages shipped by sellers are delivered during business customers’ operating hours. The requirement mainly concerns B2B sellers using seller fulfillment, third-party overseas warehouses, or local warehouses. If the rate falls below 90%, Amazon will notify sellers and provide improvement recommendations. Because business customers typically need to receive packages during working hours, weekend delivery, carrier delivery times, and the type of delivery address may affect the metric. Sellers can review shipping templates, carrier services, business-address identification, and estimated delivery times, and adjust warehouse cutoff times and delivery promises when necessary to avoid declines in B2B order performance and impacts on business-customer repeat purchases.
What does this mean for cross-border sellers?
