The International Maritime Organization has confirmed that the HNS Convention, governing liability and compensation for damage from hazardous cargo transport by sea, will enter force on 29 November 2027. After nearly three decades of delays, this creates immediate compliance obligations for Malta's ship registry and the global maritime industry, requiring new insurance certificates, reporting systems, and a two-tier compensation framework backed by both shipowners and cargo receivers.
