Peak Season Surcharge (PSS) is a temporary surcharge levied by shipping lines or carriers during peak cargo demand periods (such as before holidays or traditional shipping seasons) to cover capacity tightness and rising equipment turnover costs. It typically appears in container transport and is borne by the shipper or consignee. Use cases: the August-October Christmas stocking season in Europe and the US, the pre-Spring Festival shipping peak, etc. Notes: PSS is not a fixed fee; it is necessary to confirm with the freight forwarder before booking whether it will be charged, the amount, and the effective time; standards vary by shipping line and route, and may be adjusted at any time. Difference from GRI (General Rate Increase): GRI is a general increase in the base freight rate, while PSS is a temporary surcharge for a specific peak season; difference from BAF (Bunker Adjustment Factor): BAF fluctuates with oil prices, while PSS fluctuates with supply and demand seasonality. Foreign trade practitioners should reserve PSS costs when quoting and clearly specify the party bearing the surcharge in the contract to avoid profit erosion.
📝 Examples
1. Due to the concentrated shipment of Christmas orders from Europe and America, the shipping company has announced that starting from August 1, a Peak Season Surcharge (PSS) of USD 500 per 40-foot container will be imposed on the Asia-US West Coast route. Please adjust your quotations promptly and notify your customers.
(Note: This demonstrates the reason for the PSS, the route, and the amount, and reminds you to adjust quotations.)
2. Notice from the freight forwarder: For the cargo originally scheduled to be loaded on September 10, the shipping company has temporarily imposed an additional PSS of USD 300 per 20-foot container. Please confirm whether you accept it; otherwise, space may be affected.
(Note: This demonstrates the temporary nature of the PSS and its impact on booking decisions.)
