How should managers handle IMO amendments before they enter into force?

Many maritime authorities and shipping companies follow regulatory developments only after final adoption, or just as a treaty’s entry-into-force date approaches. This reactive approach sharply increases the risk of non-compliance, of ship detentions in port State control (PSC) inspections and of rushed costs. To build lasting compliance, senior managers should recognise four distinct stages in the life of IMO documents:

1. Discussion papers: the first presentation of ideas and challenges in committees, with no legal commitment;
2. Proposed measures: draft technical texts in working groups and sub-committees;
3. Adopted amendments: texts adopted by committees under the tacit acceptance procedure, with fixed dates of acceptance and implementation;
4. In-force requirements: binding legal rules that form the basis of audits, inspections and legal action.

A four-step method for change management and proactive compliance

Moving from a passive stance to organised monitoring needs this four-step model:

• 1. Regulatory monitoring: regular review of the agendas and reports of the main sessions (MSC, MEPC, FAL, LEG) to identify decisions under consideration early.
• 2. Applicability assessment: careful analysis of which categories of ship (by age, type and size), ports, certificates or national legislative requirements the new amendment targets.
• 3. Responsibility assignment: naming the responsible organisational unit, estimating capital or operational needs and redesigning checklists and internal systems.
• 4. Implementation tracking: continuous monitoring of progress until full readiness is assured before the official due date.

A practical example: for the requirement to operate a maritime single window (MSW) under the FAL Convention, organisations that began redesigning their data architecture and coordinating with customs immediately after the amendment was adopted in 2022 were fully compliant by the date it became mandatory (1 January 2024), while those who ignored this window faced uncoordinated document exchange and disrupted port calls.

Strategic conclusion

The time between the adoption of an amendment and its entry into force (usually between 16 and 24 months under the tacit acceptance procedure) is not a passive waiting period; it is a strategic opportunity to train staff, adjust contracts and upgrade fleets and ports.
