Maritime Services – Inventory of Hazardous Materials (IHM)


 What is an IHM?

 An Inventory of Hazardous Materials (IHM) is a document in which all potentially hazardous material onboard a vessel that can pose a risk to the health and safety of personnel or to the environment is located, identified, quantified & maintained.

 The EU SRR and the HKC, both statutory requirements, place responsibility on ship owners, ship builders, suppliers, recycling facilities and national authorities to ensure the safe and environmentally viable management of hazardous materials (hazmats) as well as the sustainable recycling of ships. A fundamental requirement of these regulations is the documentation of hazardous materials on board ships, the so-called Inventory of Hazardous Materials (IHM), and the authorization of ship recycling facilities.

 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

 Why do you need it?

 It is mandatory for all ships larger than 500 tonnes to keep an IHM. The inventory replaces the Green Passport, adopted in the Hong Kong International Convention in 2009, and is a requirement by the EU Ship Recycling Regulation 2013.

  What is the IHM Process?

 Collection of necessary information and documentation

  1. Preparation, on board visual inspection and sampling check
  2. Collected samples sent for laboratory analysis
  3. IHM prepared by trained and certified personnel
