Inventory of Hazardous Materials (IHM)

The Inventory of Hazardous Materials (IHM) is a mandatory document that identifies, quantifies, and locates hazardous substances present on board a ship, including their type, quantity, and location.

It plays a critical role in ensuring safe vessel operations and environmentally responsible ship recycling by managing hazardous materials throughout the vessel’s lifecycle.

Maintaining an accurate and up-to-date IHM is essential for regulatory compliance and operational safety.

The IHM document shall be properly maintained and updated throughout the operational life of the ship.

All ships exceeding 500 gross tons must possess a valid and certified IHM when entering EU ports or anchorages.
