A peak season surcharge is an additional freight charge applied for a defined period when transport demand, handling pressure or capacity constraints rise. It is normally added to the base freight rate and should state the affected lane, equipment, shipment type, effective dates and charging unit.
How is a peak season surcharge calculated?
The charge may be quoted per container, shipment, weight unit or freight unit. A common method is total peak surcharge = charge per unit × chargeable units.
Illustrative surcharge calculation
| Calculation step | Amount | What it means |
|---|---|---|
| Quoted surcharge | $175 per container | Illustrative carrier charge |
| Chargeable containers | 4 | Containers covered by the booking |
| Peak season surcharge | $700 | $175 × 4 |
The shipment adds $700 before any unrelated origin, destination, fuel or customs charges. The values are illustrative and are not a market rate.
What should the quotation specify?
Check the currency, unit, lane, container or service type, effective window, booking date rule and whether the surcharge applies at origin, destination or both.
How does it affect landed cost?
Allocate the surcharge using the same defensible basis used for comparable freight costs, such as container, weight, volume or shipment. Keep the allocation method consistent when comparing suppliers.
What should buyers verify?
Confirm that the shipment falls inside the published period, that the unit count matches the transport document and that the base rate has not already included the surcharge.
