Amazon FBA fee changes: what multichannel sellers need to know
The 2026 fulfilment fee adjustments hit low-price and bulky items hardest. Here is what changes and how to protect your margins.
What is actually changing
The headline is a restructured fulfilment tier for lightweight low-cost units and a revised dimensional band for oversize items. For high-volume sellers of sub-$15 products, per-unit economics shift enough to matter.
Storage utilisation surcharges also tighten, rewarding sellers who keep FBA lean and penalising stagnant inventory more sharply than before.
Fee changes do not kill catalogs, untracked fee changes do.
How to respond without panic
Re-price affected SKUs against the new landed cost, and consider shifting slow bulky items to a merchant-fulfilled channel. Commercium settlement views make real per-order margin visible so you decide on facts, not fear.
Trim aged FBA stock ahead of the surcharge date. The cheapest way to beat a storage fee is to not be storing the unit when it lands.
