Amazon Tightens Seller Fulfilled Prime Delivery-Speed Requirements — Higher One- and Two-Day Thresholds Take Effect July 6, 2026 (Announced May 26, 2026)
Amazon is raising the minimum delivery-speed thresholds that Seller Fulfilled Prime (SFP) sellers must hit to keep the Prime badge on their seller-fulfilled listings, effective July 6, 2026. For standard-size items, sellers must show a one-day delivery promise on at least 40% of Prime customer page views (up from 30%) and a two-day promise on at least 75% (up from 70%); the five-day threshold stays at 90%. Oversize items move to 15% one-day (up from 10%) and 80% five-day, and extra-large items move to 25% two-day (up from 15%) and 60% five-day. Amazon said it will launch a new tool in September 2026 that lets sellers enter shipping times, weekend shipping availability, and cut-off times at the individual delivery-zip-code level, feeding those inputs directly into Amazon's delivery-estimate calculation. As a transition cushion, weekends are excluded from the speed-metric evaluation until October 17, 2026, after which weekends are folded back into the calculation — though sellers must still fulfill weekend orders during that window. Amazon scheduled support webinars for June 8 and June 15, 2026.
Real-World Impact
A standard-size SFP seller previously needed a one-day delivery promise on just 30% of Prime page views; from July 6, 2026 that bar rises to 40% — a 10-percentage-point jump. Extra-large items see the steepest relative change: the two-day threshold climbs from 15% to 25%.
Key Points
- Effective July 6, 2026, Amazon raises SFP minimum delivery-speed thresholds across standard, oversize, and extra-large size tiers — sellers who fall below the new bars risk losing the Prime badge on seller-fulfilled listings
- Standard-size: one-day promise required on at least 40% of Prime page views (up from 30%), two-day on at least 75% (up from 70%), five-day stays at 90%
- Oversize: one-day rises to 15% (up from 10%), with an 80% five-day threshold; Extra Large: two-day rises to 25% (up from 15%), with a 60% five-day threshold
- In September 2026, Amazon will launch a tool to let sellers input shipping times, weekend shipping availability, and cut-off times at the individual delivery-zip-code level, feeding directly into Amazon's delivery-estimate calculation
- Weekends are excluded from the speed-metric evaluation until October 17, 2026, after which they are folded back into the calculation — but sellers must still fulfill weekend orders during the transition
- Amazon scheduled support webinars for June 8 and June 15, 2026, and points sellers to the Customize Your Fulfillment and Improve Delivery Speeds pages in Seller Central
What You Should Do Now
- 1Pull your current SFP delivery-speed metrics by size tier and compare them against the new July 6 thresholds (40% one-day / 75% two-day for standard) to see where you fall short before the change takes effect
- 2If you rely on a single fulfillment location, evaluate adding a regional warehouse, a faster carrier service, or 3PL coverage to lift your one- and two-day promise rates
- 3Plan to adopt the zip-code-level delivery-promise tool when it launches in September 2026 so your shipping times, cut-offs, and weekend availability feed accurate delivery estimates
- 4Use the weekend-exclusion window (through October 17, 2026) to build out weekend fulfillment capacity — weekends still must be fulfilled, and they re-enter the speed metric after that date
