The War Risk Surcharge (WRS) is applied to sea freight costs during periods of heightened risk of war or political instability in specific regions or shipping routes. This surcharge is activated when there are specific threats or conflicts that jeopardize the safety of maritime transportation. The costs of additional security measures, such as deploying armed security personnel, are passed on to customers through this surcharge. The calculation of the War Risk Surcharge may vary and is typically expressed as a fixed amount per TEU (Twenty-foot Equivalent Unit).
