Glossary Discription

Peak season surcharge is an additional fee imposed by carriers, freight forwarders, and logistics service providers during periods of exceptionally high demand when capacity constraints, increased operational costs, and resource limitations justify premium pricing to manage volume and maintain service levels. These surcharges are most commonly applied in ocean freight, air cargo, and parcel shipping during predictable high-volume periods such as pre-holiday retail seasons, Chinese New Year manufacturing rushes, back-to-school shipping peaks, and harvest seasons for agricultural products. Carriers implement PSS to offset the increased operational expenses associated with peak demand including overtime labor costs, equipment repositioning, additional temporary facilities, and premium rates for subcontracted capacity. The surcharges are typically announced weeks in advance with specific effective dates and applicable trade lanes, allowing shippers to plan accordingly or adjust shipping schedules to avoid peak periods. PSS amounts vary based on service type, origin-destination pairs, and demand intensity, ranging from modest percentages to substantial per-container or per-shipment fees.
