Panama City, 8 August 2025 — The Panama Maritime Authority (PMA) has introduced Merchant Marine Circular (MMC-404), establishing a compulsory Pre-Arrival Checklist for Panama-flagged vessels calling at ports under the oversight of the United States Coast Guard (USCG), Paris Memorandum of Understanding (Paris MoU), Australian Maritime Safety Authority (AMSA), and the China Maritime Safety Administration (MSA).
The circular, issued on 31 July 2025 and now in effect, replaces and consolidates MMC-381, MMC-393, MMC-398, and MMC-402. It is intended to strengthen the operational readiness of the Panamanian merchant fleet, reduce the likelihood of Port State Control (PSC) deficiencies, and minimise the risk of vessel detentions.
Under MMC-404, the completed Pre-Arrival Checklist must be submitted to prearrival@amp.gob.pa 120 hours before arrival at a covered port. For voyages lasting less than 96 hours, the submission must be made at least 24 hours prior to arrival. The checklist is mandatory for all Panama-flagged vessels, except passenger ships, and must be signed by the Master and/or the Designated Person Ashore (DPA).
Non-compliance may result in administrative sanctions against the Master, Chief Engineer, and/or the vessel’s operating company.
The circular also requires immediate reporting of any serious equipment failures or other issues that cannot be resolved onboard before arrival. In such cases, operators must prepare a corrective action plan, set timelines, conduct a risk assessment, and coordinate with the vessel’s Recognized Organization (RO) and Segumar Offices. Notification to the relevant Port State Control authority is also required in accordance with SOLAS Chapter I, Regulation 11.
Impact on the Marine Industry
The introduction of MMC-404 is expected to have a notable effect on vessel operations and compliance procedures.
- Operational Planning: Masters and operators will need to integrate the checklist submission timeline into voyage schedules, ensuring sufficient time for preparation and verification.
- Compliance Burden: Companies may require dedicated personnel to handle checklist submission and tracking to avoid last-minute errors.
- Port State Control Outcomes: Early detection of deficiencies through the checklist could reduce detentions and improve the standing of Panama-flagged vessels in PSC regimes such as the US, Paris MoU, Australia, and China.
- Financial Implications: Fewer detentions mean lower risk of delays, penalties, and off-hire costs, while non-compliance could attract fines or sanctions.
- Industry Influence: If successful, MMC-404 could prompt other flag states to adopt similar proactive PSC compliance measures, leading to broader industry changes.
