Amazon's 90% Business Hour Delivery Rule Hits September 30
You have three weeks. As reported across multiple seller-news outlets and confirmed in Seller Central, Amazon requires a Business Hour Delivery Rate of 90% or higher on applicable seller-fulfilled shipments starting September 30, 2026. Sellers still below the line by October 30 can have their seller-fulfilled offers deactivated for Amazon Business customers.
This is not another dashboard metric you can look at next quarter. It targets a specific, profitable slice of your revenue, and the enforcement date is already on the calendar.
What is the Business Hour Delivery Rate and how is it measured?
The Business Hour Delivery Rate measures whether your seller-fulfilled order arrived during the buyer's operating hours, not merely whether it arrived by the promised date. A package that lands at a closed loading dock at 7pm counts against you even though it was technically on time.
As reported, the metric runs on a rolling 14-day window and applies in the US, UK and Germany. Confirm the current scope and your own rate in Seller Central before you act on any of this.
Applies to: seller-fulfilled offers shown to Amazon Business customers
Threshold: 90% or higher, as of September 2026
Measurement: rolling 14-day period
Markets: US, UK and Germany
Consequence: seller-fulfilled offers may be deactivated for Amazon Business buyers if the rate has not improved by October 30
Does this shut down my whole Amazon account?
No. This is scoped to seller-fulfilled offers served to Amazon Business customers. Your FBA offers and your standard retail offers are not affected by this particular rule.
That scoping is worth understanding properly, because the panic version of this news circulating in seller groups is wrong. The realistic downside is losing your B2B offers, and for sellers with a meaningful Amazon Business share that is painful enough on its own.
Why business hour delivery is harder than it sounds
Standard consumer delivery targets a home address where someone is usually around in the evening. B2B is the opposite. Offices close. Receiving departments keep their own hours. Loading docks shut at 4pm.
Most FBM operations were never built around this. You picked a carrier on landed cost and transit days. Neither of those tells you what time of day the parcel gets handed over, and that is now the number Amazon grades you on.
Pull your current Business Hour Delivery Rate in Seller Central and see where you actually stand against the 90% line
Break the failures down by carrier and by service level, not by ASIN. This is a logistics problem, not a listing problem
Check your cut-off times. A late-afternoon handover often becomes a next-day evening delivery
Ask your carriers directly what delivery-window control they offer on business addresses, and what it costs
For lanes you cannot fix in time, work out whether moving that selection to FBA before the deadline is cheaper than losing the B2B offer
What should you do if you are already below 90%?
Treat the October 30 date as your real deadline and the September 30 date as the day the clock starts. Because the metric is a rolling 14-day figure, changes you make in early October can still move it before enforcement, but changes made in late October cannot.
The sellers who will struggle here are the ones running FBM at thin margins with a single cheap carrier. If that is you, the honest question is not how to squeeze the metric. It is whether that selection belongs in FBM at all.
Recommended tools
Tracking delivery performance by carrier and lane is not something Seller Central does well on its own. A dedicated inventory and fulfilment platform will surface the pattern faster. Compare the options in this inventory management tools comparison.

Get your fulfilment reviewed before September 30
Three weeks is enough time to fix a carrier problem. It is not enough time to fix it twice. If you sell to Amazon Business at any real volume and you are not confident where your rate sits, book a free account audit and we will look at your fulfilment mix, your carrier performance and what it would take to hold the line.
What is the Amazon Business Hour Delivery Rate?
It is a seller performance metric that measures whether seller-fulfilled orders to Amazon Business customers are delivered during the buyer's operating hours, rather than simply by the promised delivery date. Amazon requires 90% or higher from September 30, 2026.
When does the 90% requirement start?
September 30, 2026, as reported in Amazon's seller communications. Sellers below the threshold receive a notification, and if the rate has not improved by October 30 their seller-fulfilled offers may be deactivated for Amazon Business customers.
Does the Business Hour Delivery Rate affect FBA sellers?
No. The requirement applies to seller-fulfilled shipments to Amazon Business customers. FBA offers and standard retail offers are not covered by this rule. Confirm your own exposure in Seller Central.
Which countries does the rule apply to?
As reported, the requirement covers the US, UK and Germany. Sellers operating in other marketplaces should confirm current scope in Seller Central, since Amazon has expanded programmes like this to further regions before.
How long is the measurement window?
The metric is calculated over a rolling 14-day period. That cuts both ways: a bad fortnight drags you down quickly, but genuine operational fixes also show up in the number within about two weeks.
What happens if I fall below 90%?
Amazon sends a notification with improvement recommendations. If the rate has not recovered by October 30, seller-fulfilled offers may be deactivated for Amazon Business buyers, which removes you from that customer segment while leaving retail offers in place.
Should I move my B2B selection to FBA to be safe?
For some lanes that is the pragmatic answer, since FBA offers are outside this rule. It is a margin decision, not an obvious one. Compare the fulfilment fee against the B2B revenue at risk before committing.
Can an agency help with this?
Yes. Diagnosing delivery-window failures means reading carrier performance by lane and service level, which most sellers have never had to do. The team at AMZ Expert handles this as part of full account management.
Summary
From September 30, 2026, Amazon expects 90% of your seller-fulfilled Amazon Business orders to arrive while the buyer's premises are actually open, measured over a rolling 14 days. The exposure is limited to your B2B offers rather than your whole account, but October 30 is a hard enforcement date. If you sell B2B through FBM, audit your carrier delivery windows this month rather than next.
