Amazon Business Hour Delivery Rate: The 90% FBM Requirement Starting September 30, 2026

Starting September 30, 2026, Amazon requires seller-fulfilled offers in its US store to maintain a Business Hour Delivery Rate (BHDR) of 90% or higher; sellers below that on September 30 get a notification, and offers whose rate has not improved by October 30 may be deactivated for Amazon Business customers. FBA offers and retail offer eligibility are not affected. Data checked 2026-09-02 against Amazon’s Seller Forums announcement and three Seller Central help pages.

If you never ship your own orders, this does not touch you — the metric only exists for Fulfilled by Merchant (FBM) shipments. If you do, the number is already being calculated for you.

What Amazon Actually Announced

Amazon posted the change to the News_Amazon account in Seller Forums; the thread is timestamped June 30, 2026 (New business hour delivery requirement for seller-fulfilled shipments, checked 2026-09-02). The operative sentence: “Starting September 30, 2026, you’ll need to maintain a Business Hour Delivery Rate of 90% or higher.”

The metric’s help page carries the same transition in a banner: “Business Hour Delivery Rate is transitioning from an informational metric to a required performance standard. Starting September 30, 2026.” (Business Hour Delivery Rate (BHDR), checked 2026-09-02).

Two boundaries there are the ones sellers get wrong. The requirement is scoped to the US store in every official page describing it — no other marketplace is named. And it does not cover your whole catalogue: only FBM shipments to Amazon Business buyers at commercial addresses count, so a seller with heavy FBM volume and light B2B volume can have a low BHDR built from a handful of shipments.

BHDR joins an existing list rather than replacing anything. The Order Performance program policy (checked 2026-09-02) now carries it alongside Order Defect Rate under 1%, Late Shipment Rate under 4% and On-Time Delivery Rate at 90% or above.

How BHDR Is Calculated

The metric measures Amazon Business shipments delivered on the first attempt and within the customer’s business hours, as a percentage of your total Amazon Business shipments in a 14-day period (BHDR help page, checked 2026-09-02).

That window is not the last 14 days. BHDR covers shipments with a promised delivery date between 7 and 21 days ago — Amazon’s worked example is that on November 21 the calculation runs on shipments promised between November 1 and November 14, refreshed daily. The seven-day lag matters: a fix made today does not begin showing in the number for a week, and takes another two to wash through.

Business days and hours come from the delivery preferences the business customer set on their account. Where none are set, Amazon applies a default of Monday to Friday, 8:30 a.m. to 5:00 p.m. local time.

Two filters narrow what counts. Only tracked shipments qualify — the policy page states: “Only tracked shipments (with a valid delivery scan) will be considered for BHDR evaluation.” And commercial addresses only: an Amazon Business buyer shipping to a residential address is outside the metric.

One wording difference across the official pages is worth knowing before you argue a case. The BHDR metric page defines the measure as delivery “on the first attempt and within business hours”, and the downloadable report backs that up — its Business Hour Delivery column is defined the same way, with “First attempt on a Closed Day” listed among the failure reasons. The BHDR FAQ and the policy page summarise it more loosely as delivery “within their hours of operation”. Treat the first-attempt condition as real.

Where to Find Your Number and Your Failing Shipments

BHDR sits on the Account Health dashboard, under Program Eligibilities. Amazon’s documented steps: go to Account Health, then Program Eligibilities, click Download report, and open it from your downloads. The metric page also lists the Fulfillment Insights dashboard as a place the rate appears.

The report is the part worth your time, because it is the only place the customer’s operating hours become visible after the fact. Its columns include Order ID and Tracking ID, Promised Delivery Date, the First Attempt Delivery Date and Time, a yes/no Business Hour Delivery flag, a Failure Reason, the Customer Business Hours on First Attempt Date, Final Attempt Delivery Date and Time, Carrier Name, Ship Method, and an Is Buy Shipping flag.

Carrier plus ship method plus the Buy Shipping flag, lined up against the failure reasons, is the whole diagnostic. You are looking for one of three patterns: a service that delivers late in the day, a service that attempts on days the customer is closed, or handling times pushing the first attempt into a bad slot.

Two states confuse people. No BHDR on Fulfillment Insights means no Amazon Business shipments delivered in over three months. BHDR showing as N/A means you did deliver such shipments in the past three months, but none fell inside the latest 14-day window. Neither is a bug, and neither is a reason to relax — an N/A seller acquires a metric with a single B2B order. If you are unsure how much of your volume is B2B, start with the Amazon Business (B2B) selling guide; if the account structure itself is unclear, business account vs seller account sorts out which is which.

The Protection Path: Three Tools Together

This is the most consequential paragraph in Amazon’s documentation and the easiest to skim past. Per the BHDR FAQ (checked 2026-09-02): “Shipments fulfilled using all three tools — Automated Handling Time, Shipping Settings Automation, and Amazon Buy Shipping are automatically protected from the business hour delivery rate requirement, provided you shipped on time (as determined by the first carrier scan occurring on or before the expected ship date).”

Read the conditions rather than the promise:

1. All three, together. Buy Shipping alone does not protect a shipment; neither does AHT.
2. Only if you shipped on time. The test is the first carrier scan landing on or before the expected ship date. A late hand-off forfeits protection.
3. AHT and SSA are Professional-seller features. The FAQ prefixes both with “If you’re a Professional seller”. The 90% requirement is written against seller-fulfilled offers generally, but the documented route to immunity is not available on an Individual plan.

Automated Handling Time sets handling time per SKU from how long it has historically taken you to hand that SKU to a carrier. Shipping Settings Automation (checked 2026-09-02) calculates transit times from up-to-date carrier data, from your nearest warehouse with inventory to the customer’s address. Amazon Buy Shipping filters out shipping methods that do not adhere to the customer’s operating days, and accepts your own negotiated rates.

Amazon’s own arithmetic, from the FAQ, shows what protection is worth:

Five protected shipments out of a hundred moved a failing account to exactly the threshold. If your rate is in the low 80s, the fastest lever is not a new carrier — it is putting the three tools on the B2B slice of your volume.

Where protection is not available, the FAQ’s advice is to avoid residential shipping options for commercial addresses, confirm which carrier services guarantee Monday-to-Friday 8:30 a.m.–5:00 p.m. delivery, and use the report to prioritise your best-performing services for business shipments.

What Happens Below 90%

The announcement gives fixed dates for the first cycle: below 90% on September 30, Amazon notifies you with recommendations; if the rate has not improved by October 30, your seller-fulfilled offers may be deactivated for Amazon Business customers. It adds, verbatim: “Fulfillment by Amazon (FBA) and retail offer eligibility will not be impacted.”

The standing policy language is a rolling clock rather than a calendar date. The Order Performance program policy states Amazon sends a warning when the 14-day average is below 90%, and that if performance does not improve within 30 days of that warning, FBM offers may be deactivated for Amazon Business customers, FBA and consumer store offers unaffected. Read together: September 30 to October 30 is the first 30-day clock, not a one-off grace period.

Reactivation is documented, and it is a submission rather than an appeal. Per the FAQ: download the report from the Account Health Eligibilities page to review the flagged shipments, then click Resolve Issues and follow the instructions. To reinstate offers you must submit the specific steps being implemented and a demonstration that you understand the requirement. Amazon states it reviews the request within 72 hours.

Repeat offences carry a heavier remedy: on subsequent violations with BHDR still below the minimum, the FAQ states you will be required to use the tool combination for at least 180 days to have offers reactivated.

There is a documented exception. Asked whether delays beyond a seller’s control are excused, Amazon answers “Yes” for major fulfilment network disruptions, saying it will take steps to mitigate the impact on BHDR, and suggests pausing listings, vacation mode, or shifting inventory. Note the shape: relief is described for network-wide disruption, not an individual carrier missing an individual delivery.

Common Mistakes

• Assuming FBA coverage protects you. FBA offers are outside the metric, but they also cannot compensate for a failing FBM BHDR. If you are still weighing the models, FBA vs FBM covers the trade-offs.
• Optimising for speed instead of arrival window. A faster service landing at 6:30 p.m. fails; a slower one landing at 10 a.m. passes.
• Using residential-oriented services for commercial addresses — called out explicitly in the FAQ as not guaranteeing business-hour delivery.
• Turning on Buy Shipping and stopping there. Protection needs all three tools plus an on-time first carrier scan.
• Waiting for the number to move. With a 7-to-21-day promised-date window, changes made in late September will not show in the September 30 reading.
• Ignoring a small denominator. No minimum-volume floor is documented on any of these pages.

Checklist Before September 30

1. Open Account Health → Program Eligibilities and record your current BHDR.
2. Download the report and sort by Failure Reason; count “closed day” versus “outside hours” failures.
3. Pivot the failures by Carrier Name and Ship Method; identify the worst service still carrying B2B orders.
4. Check the Is Buy Shipping column on failing rows. If most say no, the protection path is your fastest fix.
5. Confirm you are on a Professional selling plan — AHT and SSA require it.
6. Enable Automated Handling Time, then Shipping Settings Automation, then route B2B orders through Buy Shipping. All three, or protection does not apply.
7. Verify first carrier scans land on or before the expected ship date.
8. Ask carriers which services guarantee Monday-to-Friday 8:30 a.m.–5:00 p.m. delivery, and reserve those for commercial addresses.
9. Re-check weekly through October, remembering the seven-day lag.
10. Keep the wider picture in view — account health rating explains how these metrics interact.

Frequently Asked Questions

Does the Business Hour Delivery Rate requirement apply outside the United States?

Every official page describing it is scoped to the US. The Seller Forums announcement introduces the requirement “in our US store”, and the BHDR metric page, the BHDR FAQ and the Order Performance program policy each open with “This article applies to selling in: United States” (checked 2026-09-02). No other marketplace is named in any of them.

Does BHDR affect my FBA listings?

No. The announcement states FBA and retail offer eligibility will not be impacted, and the policy page repeats that FBA and consumer store offers are unaffected when FBM offers are deactivated for a low BHDR. Only FBM shipments to Amazon Business customers with commercial addresses enter the calculation.

What counts as the customer’s business hours if they never set any?

Monday to Friday, 8:30 a.m. to 5:00 p.m. local time is the documented default, applied when the business customer has not indicated delivery preferences. Where preferences exist, those apply instead, and the hours used for a given shipment appear in the report’s “Customer Business Hours on First Attempt Date” column.

Can a second delivery attempt inside business hours save the shipment?

The metric page and the report’s column definitions describe the measure as delivery on the first attempt and within business hours, with “First attempt on a Closed Day” listed as a failure reason — so a successful second attempt does not appear to reverse a failed first one. Final attempt date and time are recorded separately, which helps diagnosis but is not the field the metric is built on.

How long does reactivation take after offers are deactivated?

Amazon states it reviews reinstatement requests within 72 hours. The request goes through Resolve Issues on the Account Health dashboard and must include the specific steps you are implementing plus a demonstration that you understand the requirement. On a repeat violation, Amazon states you will be required to use the Automated Handling Time, Shipping Settings Automation and Buy Shipping combination for at least 180 days before offers are reactivated.

The Bottom Line

BHDR is not a new metric; it is an old display number with a deactivation consequence attached as of September 30, 2026 in the US store. The threshold is 90%, the measurement is a 14-day window offset seven days into the past, and the only documented way to make a shipment immune is Automated Handling Time plus Shipping Settings Automation plus Buy Shipping, with an on-time first carrier scan.

The sequence is short: read your number on Account Health, download the report to find which carrier and ship method is producing failures, and decide whether you fix this by changing services or by moving B2B volume onto the protection path. Given the seven-day lag, make that decision before the last week of September. New to the dashboards involved? What is Amazon Seller Central is the orientation piece.
