Overview

Amazon is revamping the way it calculates Fulfillment by Amazon (FBA) fees for parcel‑size items across its European marketplaces. Beginning 15 October 2025 the company will drop dimensional‑weight pricing in favor of a pure unit‑weight model and will replace the existing two parcel categories with seven more granular size tiers. Sellers who rely on European FBA should prepare now because the changes are expected to lower fees for most products while reshaping pricing for a subset of items.

Key Points

• Unit‑weight‑only pricing — Fees for parcel‑size SKUs will be derived solely from the product’s actual weight, removing the previous “whichever is greater, weight or dimensional weight” rule.
• Seven new size tiers — The former “small” and “standard” classifications are being split into seven distinct tiers that align fees more closely with real handling costs.
• Staggered European rollout — The United Kingdom and several EU stores adopt the new system on 15 October 2025; the remaining European marketplaces follow on 1 November 2025.
• Expanded returns processing fee – From 1 November a returns processing charge will be added for an additional product category whose return rate exceeds a preset threshold.
• All major fulfillment programs affected – Local FBA, cross‑border UK‑EU FBA, and the Pan‑European FBA programme will all use the new fee structure.

How the New Fee Calculation Works

1. Determine unit weight — Amazon measures the exact weight of each unit as it arrives at the fulfillment centre.

   • Example: A set of silicone kitchen utensils weighs 350 g; that figure becomes the sole basis for its fee.

2. Match the unit to a size tier — The product’s dimensions are compared against the definitions of the seven new tiers, and the appropriate tier is assigned.

   • Example: A compact Bluetooth speaker measuring 22 cm × 12 cm × 8 cm falls into Tier 2, while a larger speaker of 35 cm × 20 cm × 15 cm lands in Tier 4.
