Conventions

Hague-Visby, Hamburg and Rotterdam Rules

Published 28 August 2026 · updated 22 September 2026

Cargo liability at sea is governed by an international convention rather than by ordinary contract law, because a carrier writing its own terms would exclude everything. There are four regimes in circulation. One governs the great bulk of world trade, one is in force but has been ratified by no major trading nation, one has never come into force at all, and the oldest is still the law in the United States. Knowing which applies to a shipment is a real question with a procedure behind it.

The four regimes

The practical consequence of that last line is worth stating flatly. The Rotterdam Rules are frequently written about as though they were the coming standard. They have been sitting five ratifications deep for years. Nothing on your desk is governed by them.

What Hague-Visby actually imposes

Four provisions carry most of the weight, and each of them is narrower than newcomers expect.

Seaworthiness is a due diligence obligation, not a guarantee. The carrier must exercise due diligence before and at the beginning of the voyage to make the ship seaworthy, properly man, equip and supply her, and make the cargo spaces fit. It is not a continuing warranty running through the voyage, and a latent defect that diligence would not have found is not a breach.

Cargo care is an active duty. The carrier must properly and carefully load, handle, stow, carry, keep, care for and discharge the goods. Where the charterparty puts loading and stowage on the charterer, the interaction between that transfer and this duty is a recurring argument.

The exceptions are a closed list, and one of them is the argument. The catalogue includes perils of the sea, fire unless caused by the actual fault or privity of the carrier, inherent vice, insufficiency of packing and a catch-all for causes arising without the carrier's fault. The one that shapes the whole regime is the exception for act, neglect or default of the master, mariner or pilot in the navigation or the management of the ship. That is the nautical fault defence, and it means the carrier is not liable for its own crew's navigational negligence.

Contracting out downward is void. Any clause relieving the carrier from liability otherwise than as the Rules provide is null and void. Contracting out upward, in the cargo owner's favour, is permitted.

Limitation and time bar, compared

The limits are unbreakable in ordinary negligence. They are lost where the damage resulted from an act or omission of the carrier done with intent to cause damage, or recklessly and with knowledge that damage would probably result, which is a demanding test and is very rarely met.

The United States is the standing exception to the whole table. It never adopted the Visby Protocol, so its statutory figure remains 500 US dollars per package or customary freight unit, fixed in 1936 and never uprated. On a high value package that limit is markedly lower than Hague-Visby; on a heavy low value one it can be higher. Do not assume the direction of the difference without working it out.

Working out which regime applies

Three routes, and they can point at different answers.

• Mandatory application. Hague-Visby applies of its own force where the bill is issued in a contracting state, where the carriage is from a port in a contracting state, or where the contract provides that the Rules govern. A state's own enacting statute may extend that further, as the United Kingdom's does.
• A clause paramount. Where the Rules do not apply compulsorily, a clause in the charterparty or bill brings them in contractually. That is what makes the regime reach charter trades at all.
• The forum. Whether a tribunal applies its own mandatory regime or gives effect to a chosen one depends on where the dispute is heard. Two forums can reach different answers on the same shipment, which is why the law and arbitration clause matters as much as the paramount clause does.

One more limit catches people. The Rules bite on contracts of carriage covered by a bill of lading or similar document of title. A voyage charterparty is not one, so the Rules do not apply to the charter as such until a bill is issued and comes to regulate the relationship between carrier and holder. Charterparties import them by clause, not by force of law.

Why Hamburg and Rotterdam failed to displace it

The Hamburg Rules were a cargo-interest reform: no nautical fault defence, presumed fault in place of the exception list, higher limits and a doubled time bar. They were adopted by states with little carrying tonnage of their own and by almost none with a lot, which left a convention in force whose commercial centre of gravity is somewhere else. A shipment to or from a Hamburg state raises a genuine conflict question, and that is the main reason to know the regime exists.

The Rotterdam Rules were more ambitious. They cover door to door rather than tackle to tackle, address electronic transport records, and let volume contracts derogate within limits. That ambition is arguably why they stalled, since a longer and more novel instrument gives every delegation more to object to. Whatever the cause, the arithmetic is in the status table above.

For anyone fixing today the working position is short. Hague-Visby is the default assumption, United States trades carry a different figure, the clause paramount is the mechanism, and the deadline that ends most cargo claims is the one-year bar rather than any argument about merits.
