What happened?
Amazon announced that it will update Seller Fulfilled Prime eligibility requirements in the UK from October 30, 2026. Products will be divided into three size tiers: standard-size, oversize, and extra-large. Prime eligibility will no longer be assessed only across the seller’s entire account, but separately for each size tier.
For standard-size products, at least 25% of detail-page views must show “delivery within one day.” For oversize products, sellers may use carriers other than Amazon Buy Shipping or Easy Ship, but must provide valid carrier tracking numbers and maintain an on-time delivery rate of at least 97%.
The new rules mainly affect sellers shipping from warehouses in the UK, overseas warehouses, and sellers fulfilling large products themselves. Sellers should check product size tiers, weekend operating capabilities, on-time shipping rates, tracking-number transmission, and one-day delivery coverage. Otherwise, a seller could lose Prime eligibility for one size tier rather than having the entire account removed from the program.
What does this mean for cross-border sellers?
UK Seller Fulfilled Prime will be assessed separately for standard-size, oversize, and extra-large products, so sellers may lose Prime eligibility for only one size tier. Monitor one-day delivery views for standard-size products and tracking numbers and on-time delivery rates for oversize products.
