IMO Treaty on Hazardous and Noxious Cargo to Enter into Force in 2027, Enhancing Global Shipping Liability Regime
The International Maritime Organization (IMO) has announced that the International Convention on Liability and Compensation for Damage in Connection with the Carriage of Hazardous and Noxious Substances by Sea, known as the 2010 HNS Convention, will come into effect on November 29, 2027. This development follows the fulfillment of conditions required for the treaty's activation, achieved on May 29, 2026. The treaty aims to close a significant gap in the international liability and compensation framework for shipping, particularly as the volume of chemicals and alternative fuels transported by sea increases. The convention mandates shipowners to maintain state-certified insurance or financial security and introduces an HNS Fund to provide additional compensation. The fund will be financed by contributions from receivers of HNS cargo in contracting states. The treaty applies the 'polluter pays' principle, ensuring compensation for those affected by hazardous cargo incidents.
