Inventory of Hazardous Materials

Keeping hazardous materials onboard your ship under control.

Empowering you to successfully compile your Inventory of Hazardous Materials (IHM) to the highest standard, ensuring legislative compliance.


IHM is a structured system to control hazardous materials onboard ships and achieve compliance with the Hong Kong Convention for the Safe and Environmentally Sound Recycling of Ships.

We empower you to successfully compile your IHM to the highest standard, and ensure legislative compliance.

What we offer

A specialist from one of our IHM Approval Teams provides support and a Dynamic PDF file to assist you with your Inventory compilation, and then takes care of the desktop approval, onboard verification and certification.

LR also offers independent approval of companies who provide shipbuilders and shipowners with IHM compilation and hazardous materials sampling/testing services against legislative requirements. To date we have checked and approved the procedures and operations of around 20 Hazardous Material expert companies.

What are the benefits?

We can help you minimise risk, potential liabilities, and enhance the safety of your ships’ crews by identifying, recording and controlling hazardous materials onboard your ships, in line with existing and forthcoming legislation.

A comprehensively compiled IHM will also assist with your in-house enviornmenal management systems and help demonstrate your commitment to safe and environmentally sound practices at the end of your ship’s life.
