Amazon Requires a 90% Business Hour Delivery Rate on Seller-Fulfilled Amazon Business Orders From September 30, 2026 — Miss It by October 30 and Your FBM Offers Can Be Deactivated for Business Buyers
Amazon has set a hard performance floor on a metric most FBM sellers have never had to manage. Starting September 30, 2026, sellers in the US store must maintain a Business Hour Delivery Rate (BHDR) of 90% or higher on seller-fulfilled shipments going to Amazon Business customers. BHDR is not about hitting the promised delivery date — it measures whether the package actually arrived during the business customer's operating hours, which means a parcel dropped at 9pm or on a day the office is closed counts against you even if it was technically on time. Amazon's announcement says sellers below 90% on September 30 get a notification and improvement recommendations; if the rate has not recovered by October 30, seller-fulfilled offers may be deactivated for Amazon Business customers. FBA offers and standard retail offers are not affected. The timing is the problem: the enforcement window sits directly on top of Q4 peak, when carrier delivery timing is at its least predictable.
Real-World Impact
The 90% floor over a rolling 14-day window is tighter than it sounds at low B2B volume. If you ship 40 Amazon Business orders in a 14-day window, four deliveries landing outside the buyer's operating hours puts you at exactly 90% — the fifth drops you below the line. At 20 orders in the window, two misses is 90% and three is a fail. Sellers with thin B2B volume have almost no cushion, which is why Amazon's three-tool combination (Automated Handling Time + Shipping Settings Automation + Amazon Buy Shipping) matters more than trying to manage the rate order by order.
Key Points
- From September 30, 2026, sellers in the US store must maintain a Business Hour Delivery Rate of 90% or higher on applicable seller-fulfilled shipments
- BHDR measures the percentage of your seller-fulfilled shipments delivered to Amazon Business customers within those customers' operating hours — it is a delivery-timing metric, not a delivery-date metric, so an on-time parcel delivered outside business hours still counts as a miss
- The metric applies only to seller-fulfilled orders going to Amazon Business and Business Prime customers at commercial addresses — FBA offers and standard retail offers are explicitly unaffected
- Amazon's announcement states the rate is measured over a rolling 14-day period, so a single bad week of carrier performance can move the number fast in either direction
- Enforcement is two-stage: below 90% on September 30, 2026 you get a notification plus improvement recommendations; if the rate has not improved by October 30, 2026, your seller-fulfilled offers may be deactivated for Amazon Business customers
- Amazon states that shipments using all three of Automated Handling Time, Shipping Settings Automation, and Amazon Buy Shipping are guaranteed to meet the requirement — that combination is the documented safe harbor, not merely a suggestion
- The metric is surfaced in the Account Health dashboard under Program Eligibilities, where a detailed report can be downloaded to see which shipments failed
- Amazon's guidance points sellers toward ground services that deliver earlier in the day; Seller Central guidance names UPS Ground, UPS Ground Saver, and FedEx Ground as carriers that perform well on this metric
- The Seller Central announcement covers the US store; trade coverage reports parallel business-hour delivery rollouts in Amazon's European stores on their own schedules — confirm your own deadline per marketplace in Seller Central rather than assuming the US date applies everywhere
- Sellers pushed back in the announcement thread on the grounds that final-mile delivery timing is carrier-controlled — packages arriving at midnight, before a business opens, or on a public holiday are cited as failures outside seller control. Amazon has not published an exemption for those cases beyond the three-tool safe harbor
What You Should Do Now
- 1Open Account Health > Program Eligibilities now and find your current Business Hour Delivery Rate — do this before September 30, because the first enforcement snapshot is taken on that date, not after a grace period
- 2Download the detailed BHDR report and look at which carrier and service level produced the failed deliveries; the pattern is usually one service delivering late in the evening rather than random noise
- 3Turn on all three of Automated Handling Time, Shipping Settings Automation, and Amazon Buy Shipping — Amazon states shipments using all three are guaranteed to meet the requirement, which is the only documented way to take carrier timing risk off your account
- 4For B2B-heavy SKUs, shift to ground services that deliver earlier in the day rather than the cheapest service; the metric rewards morning delivery windows, not lowest cost
- 5If your rate is below 90%, fix it before the October 30 checkpoint — with a rolling 14-day measurement window, changes made in early October have time to show up, but changes made in the last week of October do not
- 6If B2B is a meaningful share of your seller-fulfilled volume and you cannot get the rate above 90%, consider moving those ASINs to FBA before peak — FBA offers are exempt from this metric entirely
