Low Sulphur Surcharge, also known as Low Sulphur Fuel Surcharge, LSS or LSF, was introduced in January 2015 by the International Maritime Organization (IMO) to reduce the amount of sulphur-containing fuel used by vessels.Carriers charge a fee to cover the costs for this more expensive fuel type. These fees are called LSS, LSF or ECA (Emission Control Area) Surcharge.The LS surcharge is not a fixed amount; it varies by carrier and routing.
