Tonnage Dues refer to a form of tax or charge levied on ships based on their size or the amount of cargo they transport. It is a maritime term that applies to vessels using seaports or waterways and has historical roots dating back to the 17th century.
Tonnage Dues are typically calculated based on the ship's gross registered tonnage (GRT), which is a measurement of the total internal capacity of the vessel. The dues are often assessed per unit of weight or volume of cargo, or as a fixed fee per ship. They are imposed by port authorities or related government agencies as a means of generating revenue to maintain and develop port infrastructure, including the construction and maintenance of docks, channels, and other facilities.
These charges are generally collected to cover the costs associated with port services such as dredging, pilotage, navigation aids, vessel traffic management, and security. Tonnage Dues play a crucial role in funding the upkeep and improvement of ports, ensuring the smooth and safe passage of vessels, as well as fostering economic activity through international trade.
The rates for Tonnage Dues may vary depending on the country, port, or waterway being used. They often differ for domestic and foreign-flagged vessels, with exemptions or reduced fees offered for certain types of ships such as those engaged in fishing or recreational boating. Tonnage Dues serve as a significant source of revenue for port authorities, enabling the sustainable management and operation of ports worldwide.
