Peak season surcharges.

How they work

Peak surcharges apply during defined holiday windows. Demand surcharges add fees on specific services and package types, often scaled to how far your volume exceeds a baseline.

Why they surprise shippers

The schedules are detailed and change yearly, and they compound with your highest-volume weeks. Most shippers underestimate the total until the invoices arrive.

How to plan around them

Model your exposure before the season using your carrier's published schedule and your shipment mix, then adjust service selection and timing where you can.
