Amazon FBM: 90% of Amazon Business orders must arrive during business hours
From September 30, 2026, US seller-fulfilled shipments to Amazon Business customers must arrive during the customer's operating hours at least 90% of the time, measured over a rolling 14 days. Sellers below 90% on September 30 get a notice. If the rate hasn't improved by October 30, their FBM offers may be switched off for Amazon Business customers. Amazon says shipments that use Automated Handling Time, Shipping Settings Automation and Amazon Buy Shipping together are guaranteed to meet it.
Your net on a $10 / $25 / $50 sale: n/a / n/a / n/a
A rule, not a fee. The risk is losing Amazon Business buyers on FBM offers after October 30, 2026.
