Hong Kong International Convention for the safe and environmentally sound recycling of ships

The Inventory of Hazardous Materials has been designed to try to minimise the dangers of these hazards. The Convention defines a hazard as: “any material or substance which is liable to create hazards to human health and/or the environment".[4]

All vessels over 500 gross tonnes (GT) that are in commercial service (the convention does not apply to warships or naval auxiliary or ships operating their whole life only in waters subject to the sovereignty or jurisdiction of the State whose flag the ship is entitled to fly) will have to comply with the convention once it comes into force. Each party that does wish to comply must restrict the use of hazardous materials on all ships that fly the flag of that party.[5]

New ships must all carry an Inventory of Hazardous Materials. The inventory will list all 'hazardous materials' on board the vessel, including their amounts and locations. Existing ships must comply no later than five years after the convention comes into force, or prior to being recycled if this occurs before the five-year period. The inventory will remain with a vessel throughout its lifespan, being updated as all new installations enter the ship, as these may potentially contain hazards. The presence of the inventory will then ensure the safety of crew members during the vessel's working life, and also the safety of workers during the recycling process.

The convention was open for signature between 1 September 2009 and 31 August 2010, and remained open for accession afterwards. It will enter into force two years after "15 states, representing 40% of the world merchant shipping by gross tonnage, and on average 3% of recycling tonnage for the previous 10 years, have either signed it without reservation as to ratification, acceptance or approval, or have deposited instruments of ratification, acceptance, approval or accession with the Secretary General".[6] None of these conditions was met as of 2017:

The EU Ship Recycling Regulation [16] entered into force on 30 December 2013. Although this regulation closely follows the Hong Kong convention, there are important differences. The Regulation sets out a number of requirements for European ships, European ship owners, ship recycling facilities willing to recycle European ships, and the relevant competent authorities or administrations. It also requires the Commission to adopt a number of acts implementing the Regulation (in particular the European List of ship recycling facilities authorized to recycle ships flying the Union flag). For the Inventory of Hazardous Materials required by the EU regulation, there are additional substances listed as prohibited.[17]
