What happened?
Amazon published an update to the UK Seller Fulfilled Prime eligibility standards within the past 48 hours, with implementation planned for October 30, 2026. The new rules will no longer assess the entire account under one uniform standard, but will evaluate products by size tier, covering standard-size, oversize, and extra-large items. For standard-size products, at least 25% of customer page views must show “one-day delivery.” For extra-large products, sellers may use carriers other than Amazon Buy Shipping or Easy Ship when the carrier can provide a valid tracking number, but the relevant orders must still maintain an on-time shipment rate of at least 97%. The one-day delivery requirement for standard-size products and the on-time rate requirement for extra-large orders shipped with non-Amazon logistics have grace periods, with formal eligibility impact deferred until January 6, 2027. The changes mainly affect UK FBM, overseas warehouse, and self-operated logistics sellers; FBA products are not within the core scope.
What does this mean for cross-border sellers?
UK Seller-Fulfilled Prime will be assessed separately for standard-size, oversize, and extra-large products. FBM, overseas warehouse, and self-operated logistics sellers should monitor product size, delivery display, tracking coverage, and on-time shipping performance. Standard-size products need at least 25% of page views to show one-day delivery, while extra-large orders shipped through non-Amazon logistics need an on-time rate of at least 97%; these requirements formally affect eligibility assessments on January 6, 2027.
What should sellers do now?
- 1Export all UK FBM, overseas warehouse, and self-operated logistics Prime products this week. Label each ASIN by standard-size, oversize, or extra-large status, inventory location, and handling time, and create a complete review sheet.Dimensional weight
- 2Check tracking-number coverage and the on-time shipment rate for extra-large orders shipped through non-Amazon logistics. Flag exceptions order by order, confirm that the relevant orders meet at least 97%, and prepare a carrier and order review report.
- 3Sample standard-size Prime products to check customer page views and one-day delivery displays. Record the current percentage, identify ASINs below 25%, and prepare a handling-time and weekend-delivery adjustment list.Listing character checker
