Bangladesh deposited instruments of accession to three International Maritime Organization liability treaties on 6 July 2026, yet none of the three regimes became operative for the country on that date. The instruments cover the 1992 Protocol to the Civil Liability Convention, the 2001 Bunkers Convention, and the 2007 Nairobi Wreck Removal Convention.

The timing is precise. The IMO record shows the Bunkers and Nairobi Conventions enter into force for Bangladesh on 6 October 2026. The 1992 Civil Liability Protocol enters into force on 6 July 2027. The state news agency BSS presented the accessions as a way to secure compensation without prolonged litigation. That account captures the treaties' remedial ambition, but it risks treating accession, entry into force, and domestic implementation as the same legal event.

What does accession actually trigger?

Deposit on 6 July 2026 expressed Bangladesh's consent to be bound. It started three separate legal clocks. Each convention addresses different risks and should not be treated as one undifferentiated model.

• The 1992 CLC Protocol (Articles III and VII(1), (8)) channels liability for persistent cargo-oil pollution from tankers to the registered owner, subject to limited defences. Ships carrying more than 2,000 tonnes of persistent oil in bulk as cargo must maintain compulsory insurance, and claimants may sue the insurer directly.
• The Bunkers Convention (Articles 1(3), 1(5), 3 and 7) covers pollution from fuel used or intended for a ship's operation, defines "shipowner" more broadly, and requires insurance for registered owners of ships over 1,000 gross tonnage.
• The Nairobi Convention (Articles 7–9 and 12) concerns locating, marking and removing hazardous wrecks, with insurance certification for ships of 300 gross tonnage and above.

Bangladesh's instrument included a declaration under Nairobi Article 3(2), extending the Convention from its default convention area to its territory, including the territorial sea.

Why does the missing Fund matter?

The largest remaining gap is Bangladesh's non-accession to the 1992 Fund Convention. The Civil Liability Convention is the shipowner layer of a two-tier tanker pollution regime. When valid claims exceed the shipowner's limit, or first-layer compensation is unavailable for specified reasons, the Fund supplies additional compensation. The IOPC Funds state that the combined maximum is 203 million Special Drawing Rights for qualifying incidents, including amounts paid under the CLC. The Fund is therefore not a separate 203 million SDR layer on top of the shipowner's payment.

Membership carries real costs. Articles 10 and 15 place annual contributions on persons in a member state who receive more than 150,000 tonnes of contributing oil after carriage by sea — not directly on the state treasury. Article 14 permits, but does not require, the state to assume a contributor's obligations.

The current IOPC membership list does not record Bangladesh as a Fund party. It records India, Sri Lanka and Maldives as parties to both the 1992 Civil Liability and Fund Conventions. The result is a regional asymmetry. A qualifying tanker spill affecting Bangladesh after July 2027 could engage the shipowner and insurer layer, while Bangladeshi claimants would remain outside the industry-financed second tier.

What do the incidents show?

The Sundarbans record requires care. A joint United Nations–Bangladesh assessment describes the tanker OT Southern Star as carrying 357,664 litres of heavy fuel oil in an inland river casualty. The official record does not establish the sea-going element required by CLC Article I(1). The IOPC Director reported a low likelihood of Fund involvement and said only that the incident could have become a Fund incident if pollution entered Indian territory. That was conditional, not a coverage determination.

A fire aboard MT Banglar Saurabh at Chattogram's outer anchorage in October 2024 illustrates ongoing tanker risk. The Bangladesh Navy reported that its response prevented crude oil from spreading into the Karnaphuli River and Bay of Bengal. It was not a completed CLC/Fund pollution incident.

A scope tension also remains. Bunkers covers operational-fuel pollution from sea-going ships. CLC/Fund covers persistent oil carried as cargo by sea-going tankers. Coal and fly ash fall outside both.

How does international law frame implementation?

UNCLOS Articles 192 and 194 require protection of the marine environment and measures to prevent, reduce and control pollution. Article 235(2)–(3) connects those duties to recourse for prompt and adequate compensation and to cooperation on compulsory insurance and compensation funds. ITLOS has explained that Article 194(1) due diligence requires a functioning national system of legislation, administrative procedures, enforcement and vigilance (paras 234–235).

Domestically, Bangladesh's official laws database still publishes the Merchant Shipping Ordinance 1983. Sections 471–472 contain a general shipowner limitation framework, but the Ordinance predates the three instruments deposited in July 2026. The Admiralty Act 2000 designates the High Court Division as the Admiralty Court, yet jurisdiction over maritime claims does not itself create every convention right or procedure. A claimant invoking direct action still needs domestic rules on the competent court, permissible insurer defences, service, limitation-fund procedure, recognition of foreign certificates, and enforcement.

The IMO's Legal Committee has noted that a Bunkers claims manual could assist claimants, promote uniform treatment of claims and reflect the role of national courts in determining the nature and admissibility of claims. The IOPC guide for member states recommends advance claims-handling arrangements, including coordination with insurers and communication with affected communities.

What remains unsettled?

A limitation issue persists. Bunkers Article 6 and Nairobi Articles 10(2) and 12 preserve the right to limit liability under applicable national or international regimes, including the 1976 LLMC as amended. Bangladesh does not appear in the IMO's August 2026 lists of parties to the 1976 LLMC or its 1996 Protocol. The 1983 Ordinance contains limitation provisions, but its figures are expressed in taka, while the Protocol limits — increased by the 2012 amendments — use Special Drawing Rights.

The joint UN–Bangladesh assessment after Southern Star identified weak inland-vessel management, very low oil-spill preparedness, unclear agency mandates, and the need for a claims programme and staff capacity. The article's analysis recommends a sequenced programme: convention-specific legislation covering certificates, direct action, jurisdiction, limitation funds, judgment recognition and time bars; an assessment of Fund accession with the required oil-receipt reporting architecture; alignment of the limitation regime with international standards; and a claims protocol for affected communities.

The legal conclusion is narrower than the public narrative, but more consequential. Bangladesh has validly entered the treaty process and made the correct Nairobi territorial-sea declaration. It has not yet completed the legal and institutional compensation system. Until the Fund layer, implementing legislation, limitation rules and claims machinery are in place, the conventions will allocate international obligations without guaranteeing an effective domestic route from maritime damage to payment. Maritime liability should be measured not at the moment of accession, but at the point where an affected claimant can convert damage into compensation.
