Amazon are updating Fulfilled by Merchant (FBM) requirements for Amazon.co.uk, which they say will increase your conversion with more accurate delivery promises, ensure timely deliveries for business customers and facilitate smooth customs clearance.
Deliver reliably to Amazon Business customers during their 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 from the 30th of September 2026.
This metric measures the percentage of FBM shipments delivered to Amazon Business customers within their hours of operation.
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 Account Health Dashboard.
Improve your delivery promise with more accurate handling time
In Amazon’s UK store, 90% of FBM orders already ship within one day handling time. Reflecting this, starting on the 15th of July 2026, 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).
Amazon to shorten your handling time automatically
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 ‘to make it easy for you to offer faster delivery promises’ that reflect your actual performance.
To learn how to monitor your SKU-level handling time, go to Modify handling time.
Ensure 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 carrier authorised to provide correct customs documentation and supply your carrier with Amazon’s IOSS number and ASIN details for each product. For more information, go to Changes to programme policies.
