The International Maritime Solid Bulk Cargoes (IMSBC) Code is poised for significant amendments set to come into force on January 1, 2025. These amendments, according to Captain Akshat Arora, a Senior Risk Assessor, are pivotal for members involved in the transport of solid bulk cargoes to ensure compliance. Some contracting governments may even adopt parts of these amendments voluntarily from January 1, 2024.

The Significance of IMSBC Code Amendments

The IMSBC Code, a critical component of maritime safety regulations, ensures the safe stowage and shipment of solid bulk cargoes. The upcoming amendments aim to enhance maritime safety further by addressing specific discrepancies and introducing new requirements.

Key Changes in the Amendments

Revised Cargo Information and Declaration Form

Under the new amendments, the cargo information section (Section 4.2 of the IMSBC Code) will now include a mandatory sub-item for the cargo’s bulk density, as per SOLAS regulation XII/10. This change is crucial for accurately assessing the cargo’s properties and ensuring safe transportation.

Expansion of Non-cohesive Cargoes List

The amendments extend the list of non-cohesive cargoes in Appendix 3, including various new cargoes like BARYTE and ELECTRIC ARC FURNACE DUST, PELLETIZED. This extension mandates determining the angle of repose for these cargoes before loading to apply the appropriate trimming provisions.

Updated Exemptions for Fixed Gas Fire Systems

A noteworthy update is the 6th revision of the list of Solid Bulk Cargoes exempt from having a fixed CO2 fire-fighting installation onboard. This revision includes the new cargo “ELECTRIC ARC FURNACE DUST, PELLETIZED.”

Detailed Examination of Amendments

Importance of Bulk Density Information

The inclusion of bulk density information is a vital step in aligning the IMSBC Code with SOLAS XII/10 requirements. It aids in the accurate verification of solid bulk cargoes’ density, enhancing cargo and ship safety.

The Extended List of Non-cohesive Cargoes

The extended list of non-cohesive cargoes underscores the importance of understanding cargo properties to apply the correct safety measures, such as trimming provisions under section 5 of the IMSBC Code.

The Revised Exemptions for Fire Safety

The updated exemptions reflect ongoing efforts to tailor fire safety requirements to the specific risks associated with certain cargoes, thereby optimizing safety protocols onboard.

Compliance and Enforcement

Voluntary Compliance Ahead of 2025

The Maritime Safety Committee encourages early compliance with the revised cargo information form, highlighting the industry’s proactive approach to safety.

Recommendations for Ship Operators and Shippers

Ship operators and shippers are advised to familiarize themselves with the new requirements to ensure smooth transitions and compliance ahead of the mandatory enforcement date.

Role of Port State Control Officers

Port State control officers play a crucial role in enforcement, using discretion in the interim period until the amendments formally come into force.

Implications for Maritime Safety and Efficiency

These amendments signify a significant leap forward in maritime safety, ensuring that cargo handling and shipping practices keep pace with the evolving demands and standards of the industry.


The forthcoming amendments to the IMSBC Code mark a pivotal moment for maritime safety and operational standards. As the maritime community prepares for these changes, the emphasis on compliance and proactive measures remains paramount.
