Inventory of Hazardous Materials (IHM) data now available on online product catalogue

Customers can now retrieve essential information and documents on IHM classifications at their fingertips for improved safety and simplified compliance.

An Inventory of Hazardous Materials (IHM) is an important document containing information regarding potentially hazardous materials on board a vessel. Improper handling and disposal of hazardous materials can cause environmental pollution and threaten the safety of crew members.

Apart from minimizing risks to protect crew members, IHM also ensures compliance with regulations such as the Hong Kong Convention and EU Ship Recycling Regulation (1257/2013).

IHM for new and existing vessels

The IHM for new and existing ships are vastly different. For new vessels, the shipyard is primarily responsible for establishing the IHM based on material declarations and information from suppliers to identify the location and quantity of Hazardous Materials on-board.

As for existing vessels, the shipowner will have to prepare the IHM based on several processes like samplings, analyses and interpretations of results. Changes on board the vessel while it is still in operation would require a mandatory update to the IHM. When a ship reaches the end of its lifespan, a final investigation for Hazardous Materials is conducted and are transported to a waste facility to be scrapped safely.

Our products have been IHM-classified for your convenience

In accordance with existing regulations, certified personnel at WSS have carefully reviewed and classified our portfolio of more than 2,700 standard products with potentially hazardous materials. This helps to ease regulatory compliance, as well as to simplify the shipowners’ preparation of an IHM report, be it for new or existing vessels, or vessels ready for recycling.
