What happened?
Amazon’s UK seller policy page states that, from September 30, 2026, UK FBM sellers must maintain an in-business-hours delivery rate of at least 90%, primarily for seller-fulfilled orders. Amazon recommends choosing reliable carriers and accurately setting order handling times and transit times. Sellers can also use Automated Handling Time, Shipping Settings Automation, and Amazon Buy Shipping to reduce the potential impact of inaccurate delivery promises. For cross-border orders shipped from the UK or other non-EU regions to EU addresses, sellers must also comply with new EU customs reform requirements. For parcels valued below €150 and using IOSS, sellers should choose carriers that can provide correct customs documents and provide the carrier with Amazon’s IOSS number and the ASIN for each product. The changes mainly affect UK FBM sellers, sellers shipping cross-border from the UK to the EU, and Chinese sellers relying on low-value direct-shipping models.
What does this mean for cross-border sellers?
UK FBM sellers should recheck handling times, transit times, and carrier performance before September 30, 2026, to ensure an in-business-hours delivery rate of at least 90%. For low-value IOSS parcels shipped from the UK or other non-EU regions to the EU, also verify the customs documents, Amazon’s IOSS number, and product ASIN information.
What should sellers do now?
