IHM Part I reports, which are prepared according to the MEPC.269(68) 2011 Guidelines for the Development of the Inventory of Hazardous Materials, shall be certified by the flag states or by recognized organizations (ROs).

The EU SRR requires investigation of 15 hazardous substances, listed in Annexes I and II to the regulation, while HKC requires 13. In the table below, you can see the details of the Annexes and Appendices as well as the details of the IHM.


What is the IHM?

The IHM is a list of hazardous materials that are present on a ship. The IHM quantifies and locates hazardous materials on board ships which are known to represent a potential hazard to people and the environment. For assuring a safe and environmentally friendly handling of these materials, detailed documentation of those materials in the ship’s structure and equipment, and in stores, is essential.

The IHM consists of three parts:

  • Part I: Hazardous materials contained in the ship’s structure and equipment
  • Part II: Operationally generated wastes
  • Part III: Stores

The IHM Part I is prepared either during the construction of the ship or while the vessel is in operation. It is maintained and kept up to date until the end of the ship’s life.

IHM preparation for new ships

For newbuilding projects, the IHM Part I is prepared by the shipyard. The IHM is based on Material Declarations (MD) and the Supplier’s Declaration of Conformity (SDoC) provided for all machinery, equipment, materials and coatings installed on board a vessel. The MD and SDoC contain information on whether hazardous materials, as listed in Annexes I and II of the EU SRR and/or Appendixes 1 and 2 of the HKC, are present in the specified products.

New ships flying the flag of an EU/EEA member state are required to have on board an IHM Certificate (IC) issued on behalf of the flag, starting from 31 December 2018.

IHM preparation for ships in operation

The ship owner is responsible for the preparation of the IHM Part I for ships in operation. IHM reports are prepared by hazmat experts, based on document analysis and on-board investigation through sampling and visual checks.

For ships in operation flying the flag of an EU/EEA member state, the IHM Certificate issued on behalf of the flag is required starting from 31 December 2020.

For ships in operation flying the flag of a third country (non-EU/EEA flag) but visiting EU/EEA ports or anchorages, the IHM Statement of Compliance (SoC) is required starting from 31 December 2020.

EU/EEA member states’ port authorities will be authorized to control ships in order to verify whether they have a valid IHM Certificate or SoC, or a Ready for Recycling Certificate (RfRC), on board.
