From Amazon's 2026 US FBA fulfillment fee changes and product size tiers pages, read 2026-10-21. Amazon charges the fee when the unit leaves the warehouse, so a unit ordered before 15 October and shipped after it pays the peak rate.

It depends on the size tier, the shipping weight and the price. A small standard unit under 2 oz priced $10 to $50 is $3.32 before the 3.5% surcharge; Amazon's own example, an iron of 3.35 lb, is $7.13, or $7.38 with the surcharge.
From 15 October 2026 to 14 January 2027, Amazon charges peak rates on units shipped in that window. The same iron is $7.67 at peak, before the surcharge.
Since 17 April 2026, Amazon adds 3.5% to every US FBA fulfillment fee, peak and non-peak alike.
Length × width × height in inches, divided by 139. Bulky and extra-large items are measured with a minimum width and height of 2 inches. Amazon charges the greater of unit weight and dimensional weight, except for small standard and extra-large 150+ lb units, which pay on unit weight.
Yes. Products priced under $10 get Amazon's Low-Price FBA rates, about $0.86 less per unit than at $10 or more, on average. Products over $50 pay a little more.
The $10 to $50 band. Below $10 is the low-price band, and above $50 the higher one.
Monthly storage, the inbound placement service fee, a low-inventory-level fee when stock falls below 28 days of supply, returns processing when Amazon gives the buyer free return shipping, and removal or disposal when you take stock out.
