Important Update on Hazardous Materials Inventory for Liberian Flag Vessels

The Liberian Maritime Authority has recently issued a critical update regarding the Inventory of Hazardous Materials (IHM) required for ships registered under the Liberian flag. This update aligns with the Hong Kong Convention (HKC) and addresses compliance with both European Union and International Maritime Organization regulations. Refer a Attachment.

New Survey Requirements:
Starting from April 1, 2024, the Administration will directly conduct all surveys related to the IHM for vessels both currently registered and those registering with Liberia. This transition from Recognized Organizations (ROs) to the Administration marks a significant change in the procedure to enhance the consistency and oversight of hazardous material management.

Compliance Deadlines:
Vessels calling at any European Union port are required to have a valid Inventory Certificate on Hazardous Materials (ICIHM) onboard. Additionally, for ships visiting non-EU ports worldwide, the same certification is mandated by June 26, 2025, or before the vessel goes for recycling if this occurs sooner. This ensures that all Liberian-flagged vessels meet the necessary environmental protection and safety standards regardless of their operational areas.

Certification Process:
The Administration’s auditors are empowered to issue the ICIHM, referencing the EU Ship Recycling Regulation (EU SRR), to meet both EU and IMO requirements. Notably, additional shipboard inspections may not be necessary if the IHM has been properly maintained and updated as required by the regulations.

Survey Integration Options:
Surveys for the IHM can be conducted either as standalone services or integrated with other routine inspections, such as the Annual Safety Inspection (ASI) or audits under the ISM Code, ISPS Code, and Maritime Labour Convention (MLC).

Documentation for Full-term Certification:
To obtain a full-term certificate, vessel operators must submit the following documentation to the Administration by June 26, 2025:

  • An initial IHM Part I report and updated maintenance records compliant with MEPC.379(80).
  • The existing Statement of Compliance or International Certificate on IHM previously issued by classification societies.

Scheduling and Fees:
For details on how to schedule a survey, including options to advance or extend the date of the ASI, and information on associated fees, stakeholders should contact the Administration via email at
