BIMCO (Baltic and International Maritime Council) is the world's largest shipping organisation representing ~65% of global tonnage. Its safety advisories are referenced in standard Charter contracts, so a BIMCO Hormuz rating directly affects insurance, deviation rights, and vessel scheduling.Source: BIMCO / Lowdown

Has BIMCO advised ships to use Iran's Hormuz toll system?

As of 7 May 2026, BIMCO had not issued updated Hormuz safety guidance following Iran's creation of the Persian Gulf Strait Authority, leaving vessel operators without authoritative industry direction on registering with the PGSA.Source: Lowdown

How does BIMCO's silence on PGSA affect shipping insurance?

Most war-risk insurance clauses reference industry advisories. Without a BIMCO advisory classifying the PGSA or the Hormuz corridor, underwriters are applying their own judgement, resulting in wider premium spreads and inconsistent cover terms.Source: Lowdown

Background

The Baltic and International Maritime Council (BIMCO) is the world's largest international shipping organisation by direct membership, founded in 1905 and headquartered near Copenhagen, Denmark. Its members include shipowners, operators, managers, brokers, and agents responsible for roughly 65 per cent of global tonnage. BIMCO drafts standard Charter-party contracts that underpin the bulk of international seaborne trade, issues safety advisories that carry contractual weight in most time-Charter agreements, and represents the Shipping Industry before the International Maritime Organisation and national regulators. Unlike trade associations that lobby on behalf of members, BIMCO's primary function is documentary and normative: its contracts and advisory ratings create the operational language the industry runs on.

The practical significance of a BIMCO advisory is embedded in standard contract law. Most time-Charter contracts contain war-risk clauses that reference industry advisory bodies; a BIMCO designation of an area as a war zone or high-risk zone can trigger additional war-risk premium requirements, owner deviation rights, or charterer cancellation rights without either party needing to negotiate the trigger separately. This means BIMCO guidance functions as a semi-automatic market signal: publication of an advisory or its deliberate withholding both move markets and reshape vessel routing decisions.

BIMCO's standards and advisories are used across all major shipping sectors and routes, from bulk carriers on the Pacific grain trade to tankers on The Atlantic oil corridor. Its influence extends beyond its member base because its standard contracts are adopted by non-members under commercial pressure from counterparties who insist on BIMCO forms. The organisation's ability to set a neutral, non-governmental benchmark for safety and contractual practice makes it one of the few international bodies with practical authority over day-to-day shipping operations that is not itself a state or inter-governmental organisation.

More questions

What does BIMCO do and why does its guidance matter?

BIMCO is the world's largest direct-membership shipping organisation. It drafts standard Charter-party contracts and issues safety advisories that are referenced in most time-Charter war-risk clauses, giving its guidance the force of contract across the Shipping Industry.Source: BIMCO

What is a BIMCO advisory and what effect does it have?

A BIMCO advisory is an official safety or risk assessment for a shipping area or route. When it designates a zone as high-risk or a war zone, most standard time-Charter contracts automatically trigger premium requirements, deviation rights, or cancellation rights.Source: BIMCO standard charter-party forms

Why has BIMCO not updated its Hormuz safety guidance?

BIMCO has withheld updated Hormuz guidance because publishing an advisory that either endorses or rejects Iran's Persian Gulf Strait Authority toll regime could be read as implicit recognition of Iranian authority over the strait. Western flag states have privately signalled that engagement with the PGSA is politically sensitive.Source: industry reporting

How is BIMCO different from the International Group of P&I Clubs?

BIMCO is a shipowners and operators trade association that sets contracts and advisories. The International Group of P&I Clubs is the umbrella body for marine liability insurers. BIMCO provides the contractual and advisory framework; P&I Clubs provide the insurance. Both influence whether ships can move commercially, but through different mechanisms.Source: BIMCO / International Group

Does BIMCO have authority to close a shipping route?

No. BIMCO has no enforcement powers. Its influence is contractual: when its advisories are embedded in Charter-party war-risk clauses, an adverse designation effectively makes a route commercially unusable without legal obligation from any government.Source: BIMCO

BIMCO About BIMCO

How the World Sees Them

Iran

Tehran's PGSA launch received zero registrations in its first 24 hours, a failure that reflects BIMCO and operator caution rather than purely physical risk aversion.

Flag states

Open-registry states (Panama, Liberia, Marshall Islands) look to BIMCO for a non-political baseline when setting their own guidance for vessels flying their flags.

Shipping industry

Operators await BIMCO guidance before committing to novel registration requirements; the industry norm is to treat the advisory as the authoritative signal before taking on contractual or legal exposure.

Western governments

The UK and EU have signalled that registering with Iran's PGSA constitutes implicit recognition; BIMCO's silence is understood as deference to that position.
