The Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships has been in force since 26 June 2025. Ships of 500 GT and above flying a Party’s flag carry an Inventory of Hazardous Materials (IHM) and its certificate, and go only to authorized recycling yards. Existing ships have until 26 June 2030. EU-flagged ships, and non-EU ships calling at EU ports, also fall under the EU Ship Recycling Regulation.
| From | Who | Requirement |
|---|---|---|
| 26 Jun 2025 | New ships | International Certificate on Inventory of Hazardous Materials |
| 26 Jun 2025 | Every ship going for recycling (new or existing) | International Ready for Recycling Certificate |
| 26 Jun 2025 | Ship recycling facilities | Document of Authorization to conduct Ship Recycling (DASR) |
| 26 Jun 2030 | Existing ships (or earlier, before going for recycling) | International Certificate on Inventory of Hazardous Materials |

Adopted at a diplomatic conference in Hong Kong, China, in May 2009, the Convention needed at least 15 States, 40% of world merchant tonnage and recycling capacity of at least 3% of those States’ combined tonnage. Those conditions were met in 2023 and it entered into force 24 months later, on 26 June 2025. On that day IMO counted 24 Parties covering 57.15% of world tonnage, among them the flag States Japan, Liberia, the Marshall Islands and Panama, and the recycling States Bangladesh, India, Pakistan and Türkiye.
Ships covered: every ship entitled to fly a Party’s flag, a definition that includes floating platforms, FSUs and FPSOs and a vessel stripped of equipment or being towed. Not covered: ships under 500 GT, ships operating all their life only in waters of their flag Party, and warships, naval auxiliaries and other government ships on non-commercial service.
Hazardous materials: the Convention prohibits or restricts materials such as asbestos, polychlorinated biphenyls (PCBs), ozone-depleting substances, and anti-fouling compounds and systems containing organotin compounds or cybutryne.

The shipowner prepares and keeps a ship-specific IHM listing the hazardous materials on board, with their location and quantity. It is verified by the Administration or its recognized organization, following IMO’s 2023 IHM guidelines (resolution MEPC.379(80)). It has three parts:
Parts II and III are prepared before the ship is recycled. Before recycling, the owner gives the authorized yard the completed IHM so that the yard can prepare a ship-specific Ship Recycling Plan.

Port State control: a ship may be inspected in the port of another Party, starting with a check that it carries a valid IHM certificate or Ready for Recycling Certificate with the IHM. IMO’s FAQ says that failing to update the IHM should not on its own be a detainable deficiency; inconsistencies are reported to the flag and put right at the next survey. Failing to carry a valid certificate is among the deficiencies that may justify detention.

Regulation (EU) No 1257/2013 applies to ships flying the flag of an EU Member State, with the same 500 GT, government-ship and domestic-only exclusions. EU-flagged ships may be recycled only at yards on the European List of ship recycling facilities. Its Article 12 applies to non-EU ships calling at a port or anchorage of a Member State.
| Ship | Document | Since |
|---|---|---|
| New EU-flagged ship | Inventory certificate (IC) | 31 Dec 2018 |
| EU-flagged ship going for recycling | Ready for recycling certificate (RfRC) | 31 Dec 2018 |
| Existing EU-flagged ship | Inventory certificate (IC) | 31 Dec 2020 |
| Non-EU ship at an EU port or anchorage | Statement of compliance (SoC) with the IHM | 31 Dec 2020 |
A non-EU ship that does not comply may be warned, detained, dismissed or excluded from EU ports and offshore terminals (Article 12(5)). A ship can fall under both regimes; check with your flag State and class which certificates it needs under each.

On 26 June 2025. It was adopted in Hong Kong, China, in May 2009; its entry-into-force conditions were met in 2023 and it entered into force 24 months later. IMO reported 24 Parties at that date, covering 57.15% of world shipping by tonnage.
Ships entitled to fly the flag of a Party. It does not apply to ships of less than 500 GT, ships operating throughout their life only in waters under the jurisdiction of their flag Party, or warships, naval auxiliaries and other government ships on non-commercial service.
Under the Hong Kong Convention, an existing ship needs its International Certificate on Inventory of Hazardous Materials no later than 26 June 2030, or before it goes for recycling if that is earlier. New ships have needed one since 26 June 2025.
Part I lists hazardous materials in the ship's structure and equipment and is kept up to date through the ship's life. Part II covers operationally generated waste and Part III covers stores; both are prepared before the ship is recycled.
The certificate issued after the final survey, once the IHM, the ship recycling plan and the facility's authorization have been checked. The Administration sets its validity, which may not exceed three months.
Yes. Regulation (EU) No 1257/2013 applies to ships flying an EU flag, which may be recycled only at facilities on the European List, and its Article 12 applies to non-EU ships calling at an EU port or anchorage. Since 31 December 2020 those non-EU ships have been asked for a statement of compliance together with their IHM.
