Peak fulfilment fees also run 15 Oct 2026–14 Jan 2027 in US (~$0.32 average uplift) and UK (see UK peak fees update).

Who’s affected
FBA sellers sending stock for Black Friday / festive demand in US and UK.
What to do
- If you missed the window, switch priority ASINs to FBM/3PL rather than hoping for late FBA receiving.
- Create remaining inbounds only when capacity allows; do not spam failed shipment plans.
- Recalculate days of cover with longer FBA lead times through peak.
- Read our missed-cutoff blog for a recovery checklist.
Why it matters for replenishment
Policy, fee and inbound changes move the dates and unit economics behind reorder points. Update lead times, landed cost and channel buffers in the same week Amazon publishes the change — not after the stockout.
