2026 fulfillment rates

The built-in Amazon US rate card uses the official January 15, 2026 price bands and the peak schedule beginning October 15, 2026. The 3.5% fuel and logistics surcharge effective April 17, 2026 is enabled by default and can be switched off if Amazon withdraws it.

Dimensional and billable weight

Large standard and bulky tiers use the greater of unit weight and dimensional weight, calculated as packaged length × width × height divided by 139. Small standard uses unit weight under Amazon's published rules.

Frequently Asked Questions

Are these official Amazon charges?

The built-in fulfillment and referral rules are transcribed from official Amazon US pages and dated in the interface, but the result is an estimate. Seller Central remains authoritative for a specific SKU.

What is not included?

Conditional costs such as returns, taxes on fees, aged or low inventory, overmax, packaging, removals, inbound defects, promotions, and program-specific discounts are not automatic. Add known amounts under other costs or use the manual fulfillment fee.

Why can the selected size tier be rejected?

Each tier has a published weight range. Correct the tier or packaged weight, or enable the custom fulfillment fee when Seller Central provides a special rate.
