Amazon are updating the UK FBM requirements for Amazon.co.uk. These will, they say, help increase your conversion with more accurate delivery promises, ensure timely deliveries for business customers and facilitate smooth customs clearance.
Deliver Amazon Business customers in operating hours
To ensure secure delivery and fewer delivery reattempts, Amazon expect that you maintain a business hour delivery rate of 90% or higher starting on the 30th of September 2026. This moves from an informational metric to a required performance standard.
The metric measures the percentage of FBM shipments delivered to Amazon Business customers within their hours of operation. The policy applies to sellers with 20 or more tracked FBM shipments to Amazon Business customers with commercial addresses in the trailing 14-day measurement window. Sellers with fewer than 20 shipments will not be evaluated under this policy.
From the 30th of October, if your performance remains below the requirement set out in the policy, non-compliant listings may be deactivated for business customers. To review your business hour delivery rate, go to the Account Health Dashboard.
More accurate handling times
In Amazon’s UK store, 90% of FBM orders already dispatch within a one-day handling time. Reflecting this, starting on the 15th of July 2026, the account-level default handling time will only display 0-day and 1-day options.
If your account-level handling time is set to 2-days, it will automatically change to 1-day (you can still set a longer handling time per SKU).
Starting on the 1st of September 2026, if an SKU’s handling time is one or more days longer than your actual performance for more than 30 days, Amazon will enable Automated Handling Time for those SKUs making you offer faster delivery promises that reflect your actual performance.
Seamless delivery for cross-border shipments
To ensure customs clearance, you must comply with new EU Customs Reform regulations for shipments originating from outside the EU delivered to an EU address, starting on the 1st of July. For shipments under €150 imported under Import One-Stop Shop (IOSS), select an approved courier authorised to provide correct customs documentation, supply your courier with Amazon’s IOSS number and ASIN details for each product.
