Amazon Sets 90% Business Hour Delivery Rate Requirement for Seller-Fulfilled Amazon Business Orders Starting September 30, 2026 (July 2026)
Amazon has announced a new performance requirement for merchant-fulfilled (MFN) sellers who ship to Amazon Business customers in the US store. Starting September 30, 2026, these sellers must maintain a Business Hour Delivery Rate of 90% or higher — the share of seller-fulfilled shipments to Amazon Business buyers that arrive within the buyer's operating hours, measured over a rolling 14-day period. Sellers below 90% on September 30 will be notified with improvement recommendations, and if their rate has not improved by October 30, their seller-fulfilled offers may be deactivated for Amazon Business customers. The requirement applies only to seller-fulfilled shipments destined for Amazon Business customers; FBA and consumer (retail) orders are excluded. Amazon says shipments fulfilled using Automated Handling Time, Shipping Settings Automation, and Amazon Buy Shipping together are guaranteed to meet the requirement.
Real-World Impact
A seller shipping seller-fulfilled Amazon Business orders must have at least 90 of every 100 of those shipments (over a rolling 14-day window) arrive within the buyer's business hours to stay above the threshold; falling below 90% by September 30 without recovering by October 30 risks deactivation of seller-fulfilled offers for Amazon Business buyers.
