Peak Season Surcharge (PSS)
The Peak Season Surcharge (PSS) is a surcharge on sea freight costs that is applied during periods of high demand and congestion in the sea freight sector. This surcharge is intended to assist shipping companies in coping with additional operational costs and to regulate the availability of space and services when demand exceeds supply. The calculation of the PSS may vary and is typically expressed as a fixed amount per TEU (Twenty-foot Equivalent Unit).
