IHM – Inventory of Hazardous Materials & Maintenance Services
What Is the IHM?
The Inventory of Hazardous Materials (IHM) is a vessel‑specific document that identifies, locates, and quantifies hazardous materials onboard a ship. These materials are regulated under the IMO Hong Kong Convention and the EU Ship Recycling Regulation (EU SRR).
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
IHM Part I must be maintained throughout the vessel’s entire service life.
Who Must Comply?
Under the EU SRR, the following must carry a valid IHM:
- All ships ≥ 500 GT
- EU‑flagged ships
- Non‑EU ships calling at EU ports or anchorages
- Floating platforms, submersibles, and similar structures
Exemptions: Warships, naval auxiliaries, government‑operated non‑commercial vessels, and ships operating exclusively within their flag state’s waters.
Consequences of Non‑Compliance
If a vessel fails to present a valid IHM Certificate or Statement of Compliance:
- Warning
- Detention
- Dismissal from port
- Exclusion from EU ports and offshore terminals
Not maintaining IHM Part I is not detainable, but missing certificates is.
How IHM Compliance Works
For existing ships, the compliance process includes:
- Collection of ship drawings, manuals, and specifications
- Assessment of collected information
- Preparation of the Visual/Sampling Check Plan
- Onboard visual inspection and sampling
- Laboratory analysis
- Preparation of IHM Part I
- Submission to class
- Verification and issuance of Statement of Compliance
Faroe Maritime Services can handle the entire process.
IHM Maintenance – A Mandatory Requirement
All ships ≥ 500 GT must maintain IHM Part I throughout their operational life.
Shipowners must:
- Establish an IHM Maintenance Procedure & Manual
- Integrate it into the Safety Management System (SMS)
- Appoint an IHM Designated Person (IHM DP)
- Review all vessel purchases regularly (bimonthly or quarterly)
- Collect MD/SDoC for all relevant items
- Update IHM Part I when hazardous materials are added, removed, or relocated
Faroe Maritime Services provides full IHM maintenance support and can act as your externally designated IHM DP.
Digital IHM Manager System
We use an approved IHM Manager system suitable for any class and any fleet.
The system allows:
- Storage of all product data
- Upload of MD/SDoC (PDF, scanned copies, images)
- Location‑based hazardous material tracking
- Adding items stored onboard or in workshops
- Automatic versioning of IHM revisions
- Lifetime historical overview of all changes
- Restoration of deleted items (e.g., asbestos removal)
- Full audit log with user, date, and time stamps
This ensures transparent, traceable, and compliant IHM maintenance.

IHM Renewal Surveys
During renewal surveys, class surveyors verify:
- Updated and vessel‑specific IHM Part I
- Valid Statement of Compliance
- IHM maintenance procedure integrated into SMS
- Consistency between IHM and actual vessel condition
- Proper documentation for new installations, removals, or modifications
Digital IHM records are fully acceptable during surveys.
