Status of the HNS Convention and 2010 Protocol

His Excellency Mr. Ünal Çeviköz (right) signed the 2010 HNS Protocol on behalf of Turkey in London on 22 October 2011.

Entry Into Force

The 2010 HNS Protocol will enter into force 18 months after the date on which it is ratified by at least twelve States, including four States each with not less than 2 million units of gross tonnage, and having received during the preceding calendar year a total quantity of at least 40 million tonnes of cargo that would be contributing to the general account.


The Protocol was open for signature at the headquarters of the IMO between 1 November 2010 and 31 October 2011. It now remains open for accession. Ratification, acceptance, approval or accession is effected by the deposit of an appropriate instrument with the Secretary-General of IMO.

A Contributing Cargo Reporting Form for States and receivers of HNS have been developed to accompany any expression of consent to be bound by the Protocol and is designed to assist in the ratification/accession process only. If a State has not received any HNS contributing cargo, it can submit a nil declaration.

Status of Signature/Ratification

Denmark was the first State to sign, subject to ratification, the Protocol of 2010 to the International Convention on Liability and Compensation for Damage in Connection with the Carriage of Hazardous and Noxious Substances by Sea, 1996.
