The last piece of the Q4 cost picture landed this week. Amazon Shipping now has published peak surcharges, and with USPS, UPS and FedEx already committed, every major US parcel route is running holiday pricing at the same time.
Amazon Shipping, the standalone parcel service that competes with UPS and FedEx, applies peak surcharges from October 25, 2026 to January 16, 2027, with the steepest rates between November 22 and December 26. The structure is a per package demand surcharge plus extra charges for large, heavy or additional handling parcels (EcomWatch, September 6).
On the marketplace side, FBA, Remote Fulfillment with FBA, Multi-Channel Fulfillment and Buy with Prime run peak fees from October 15, 2026 to January 14, 2027, and the 3.5% fuel and logistics surcharge introduced in April applies on top (Retail Dive).
Amazon's own multichannel rate card puts the same terms in writing for MCF sellers: peak fulfilment fees effective October 15 to January 14, with the 3.5% surcharge described as offsetting elevated fuel and logistics costs (Amazon 2026 peak rate card).
The windows do not line up, and that is where the money goes missing. Amazon charges a fulfilment fee when the unit leaves the fulfilment centre, not when the customer orders it, so an order placed on October 14 that ships on October 15 pays the peak rate. Any Q4 price set from September fee math is already slightly wrong.
For a standard small item, trade reporting puts the combined effect at roughly $0.43 above the base fulfilment fee once the average peak increase and the 3.5% surcharge are both applied, scaling upward with size and weight. On a $14 item that is close to three points of margin, which is enough to turn a promotional price into a loss.
Peak fees arrive as small per unit changes spread across thousands of units, which is exactly what an account level margin chart hides. Nova reconciles fulfilment costs per unit from settlement data, so October's increase reads as a line you can point at. See Nova Profit & Loss and the FBA calculator.
