Liberia Flag — Key IHM Compliance Facts

Liberia is a long-standing Hong Kong Convention party. Below are the regulatory pillars every Liberia-flagged ship operator should track in 2026.

Second-largest open registry by gross tonnage; one of the most active maritime administrations.

Hong Kong Convention party — ICIHM is mandatory from 26 June 2025 for all Liberian-flagged vessels of 500 GT and above.

Liberian Maritime Authority requires IHM Expert acceptance for IHM service providers (Varuna Sentinels BV is on the accepted list, valid until January 2028).

MEPC Resolution 379(80) and amendments 405(83) apply to all IHM development and maintenance for Liberian ships.

Continuous IHM maintenance is enforced through annual confirmation surveys.

IHM Part I, II & III — Liberia Flag Specifics

Liberia uses an IHM Expert acceptance regime. Service providers preparing or maintaining IHM for Liberian vessels must hold a valid IHM Expert Acceptance Certificate from the Liberian Maritime Authority. Varuna Sentinels BV holds this acceptance until January 2028.

Liberia Flag IHM — Frequently Asked Questions

Is Varuna Sentinels accepted by the Liberian Registry as an IHM Expert?

Yes. Varuna Sentinels BV holds an IHM Expert Acceptance Certificate from the Republic of Liberia, confirming compliance with MEPC Resolution 379(80). The acceptance is valid until 24 January 2028.

Do Liberian-flagged ships need both HKC and EU SRR IHM?

Liberia is not an EU Member State, so the EU Ship Recycling Regulation does not apply by flag. However, Liberian ships calling at EU/EEA ports may face EU SRR scrutiny on IHM content and approved-yard selection.

How often must IHM Part I be reviewed for a Liberian ship?

Continuously throughout the vessel's operational life — every structural modification, equipment swap or hazardous-material change triggers an IHM update obligation. Annual confirmation surveys verify maintenance.

What format must Material Declarations use for Liberian-flagged ships?

Material Declarations issued on or after 26 June 2025 must follow the IMO MEPC.405(83) format with the 200 mg/kg cybutryne threshold.

Where can I find the Liberian Maritime Authority's IHM circular?

The Liberia Maritime Authority publishes Marine Operations Notes covering HKC and IHM requirements on its official website.
