The first financial quarter of 2026 marks the entry into force a suite of International Maritime Organization (“IMO”) amendments, introducing significant operational, safety, and compliance obligations. While these measures originate internationally, they directly impact Indonesian-flagged vessels and foreign vessels operating in Indonesian waters.

Indonesia has incorporated key IMO conventions into national law:

• Safety of Life at Sea (“SOLAS”) governing vessel safety procedures;
• Standards of Training Certification and Watchkeeping (“STCW”) setting qualification standards for seafarers; and
• International Maritime Dangerous Goods Code (“IMDG Code”) as the mandatory international regulation under the IMO governing the safe transport of hazardous materials by sea.

These amendments are enforced through the Directorate General of Sea Transportation (“DGST”), Port State Control (“PSC”) inspections, Harbourmaster and Port Authority Office (“KSOP”)and classification society certification.

From both legal and business perspective, these amendments go beyond procedural updates. They redefine operational responsibilities, increase regulatory scrutiny, and heighten liability exposure. Making these factors essential for investors and operators to understand when assessing risk and opportunity in Indonesia’s shipping market.

Enhanced Transparency and Container Loss Reporting

A central change under SOLAS is the mandatory reporting of containers lost at sea. Shipowners, masters, and operators must report the number, location, and circumstances of lost containers, with follow-up reports once full details are available. Reports must be submitted to both the flag state and, where relevant, the coastal state.

Implications:

Liability: Failure to report may constitute a regulatory breach, aggravating exposure in marine casualty disputes.

Insurance: P&I Clubs may impose stricter reporting conditions.

Commercial contracts: Charterparties must clarify responsibility for reporting obligations and related liabilities.

PSC inspections at major ports such as Tanjung Priok and Batam are expected to enforce these rules immediately once inquired. For investors, compliance is no longer a formality. Robust operational protocols and documentation are critical to mitigate regulatory sanctions and reputational risk.

Technical and Hazardous Cargo Compliance

The IMDG Code Amendment 42-24, now fully mandatory, introduces stricter requirements for classification, labelling, documentation, and segregation of dangerous goods. Misdeclared or improperly handled cargo carries very high enforcement risk, including civil liability, and reputational damage.

Similarly, SOLAS updates for shipboard cranes and anchor-handling winches now require load testing, certification, and Safe Working Load (SWL) marking. These requirements are particularly relevant for offshore vessels and heavy-lift operations. Non-compliance may invalidate insurance coverage and increase operational risk.

Enforcement Trends in Indonesia

Indonesian is moving towards “substance over form” enforcement. Flag state inspections, PSC audits, and KSOP oversight are expected to increase in frequency, with a focus on documentation, crew certification, and equipment compliance. Operators who treat IMO compliance as a paper exercise risk not only fines and detentions but also operational disruption and insurance disputes.

Commercial and Contractual Implications

The 2026 amendments require a proactive review of commercial arrangements. Charterparties, insurance policies, and shipper contracts must reflect the enhanced reporting obligations, training requirements, and equipment standards. Investors and operators should incorporate clauses that clearly allocate responsibilities for container loss, dangerous goods compliance, and crew certification. Proactive risk management, including updated internal compliance protocols and crew training verification, will be critical to avoiding enforcement actions and costly disputes.

From a business standpoint, operators who adapt quickly gain a competitive edge. Efficient reporting systems, certified training programs, and properly documented equipment compliance enhance operational reliability, reduce risk, and strengthen relationships with insurers and financiers. Conversely, failure to comply could delay cargo handling, lead to vessel detention, or increase insurance premiums which would directly impacting profitability.

Conclusion: Implications for Indonesia and Investors

The IMO 2026 amendments represent a structural shift in maritime compliance, enhancing safety and transparency in Indonesia’s shipping sector. For Indonesia, enforcement promotes a safer, more professionalized maritime industry aligned with national strategic objectives.

For investors, the implications are mixed. On the one hand, compliance adds operational cost and administrative complexity. On the other, the amendments enhance predictability, reduce hidden risks, to further capitalize on growth opportunities in one of the largest economies in Asia.

In essence, IMO 2026 is not just a regulatory update, it is a strategic signal. The choice for operators and investors is whether to view it as a compliance burden or as a foundation for sustainable, risk-managed, and commercially resilient shipping operations in Indonesia.
