Conventions

Hague-Visby, Hamburg and Rotterdam Rules

Published 28 August 2026 · updated 17 October 2026

A carrier's liability for cargo at sea is set by an international convention, not by ordinary contract law, because a carrier allowed to write its own terms would exclude every risk. Four sets of rules are in use. One covers most of world trade. One is in force but no major trading nation has ratified it. One has never come into force at all. And the oldest is still the law in the United States. Working out which one applies to a shipment is a real question, and there is a method for answering it.

The four regimes

The practical result of that last line should be stated clearly. Articles often describe the Rotterdam Rules as the coming standard, but they have stayed at five ratifications for years. Nothing on your desk is governed by them.

What Hague-Visby actually imposes

Four provisions matter most, and each one is narrower than newcomers expect.

Seaworthiness is a duty of due diligence, not a guarantee. Before and at the start of the voyage, the carrier must take reasonable care to make the ship seaworthy, to crew, equip and supply it properly, and to make the cargo spaces fit. This is not a promise that lasts through the whole voyage, and a hidden defect that reasonable care would not have found is not a breach.

Caring for the cargo is an active duty. The carrier must properly and carefully load, handle, stow, carry, keep, care for and discharge the goods. When the charterparty makes the charterer responsible for loading and stowing, how that transfer fits with this duty is a frequent argument.

The exceptions are a fixed list, and one of them causes the argument. The list includes perils of the sea (dangers of the sea that reasonable care could not prevent), fire (unless caused by the carrier's own actual fault or knowledge), inherent vice (a defect in the goods themselves), poor packing, and a general exception for causes that arise without the carrier's fault. The one that shapes the whole regime is the exception for the act, neglect or default of the master, crew or pilot in navigating or managing the ship. This is the "nautical fault" defence, and it means the carrier is not liable when its own crew navigates negligently.

Reducing the carrier's liability by contract is void. Any clause that frees the carrier from liability in a way the Rules do not allow has no effect. Increasing the carrier's liability, in the cargo owner's favour, is allowed.

Limitation and time bar, compared

Ordinary negligence cannot break these limits. The carrier loses the limits only if the damage came from an act or omission done with intent to cause damage, or recklessly and knowing that damage would probably result. That test is hard to meet, and it is very rarely met.

The United States is the lasting exception to the whole table. It never adopted the Visby Protocol, so its legal limit is still 500 US dollars per package or customary freight unit. That figure was set in 1936 and has never been raised. On a valuable package, the US limit is clearly lower than Hague-Visby; on a heavy, low-value one it can be higher. Do not assume which way the difference goes without working it out.

Working out which regime applies

There are three routes, and they can lead to different answers.

• Mandatory application. Hague-Visby applies automatically when the bill of lading is issued in a country that has signed the convention, when the voyage starts from a port in such a country, or when the contract says the Rules apply. A country's own law may extend this further, as the United Kingdom's law does.
• A clause paramount. When the Rules do not apply automatically, a clause in the charterparty or the bill can bring them in by contract. This is how the regime reaches charter trades at all.
• The forum. Whether a court or tribunal applies its own mandatory rules or the rules the parties chose depends on where the dispute is heard. Two forums can reach different answers on the same shipment. That is why the law and arbitration clause matters as much as the clause paramount.

One more limit often surprises people. The Rules apply to contracts of carriage covered by a bill of lading or a similar document of title. A voyage charterparty is not such a document, so the Rules do not apply to the charter itself. They only start to apply once a bill is issued and governs the relationship between the carrier and the holder of the bill. Charterparties bring the Rules in by a clause, not by force of law.

Why Hamburg and Rotterdam failed to displace it

The Hamburg Rules were a reform in favour of cargo owners: no nautical fault defence, presumed fault instead of a list of exceptions, higher limits and twice the time to bring a claim. They were adopted by countries with few ships of their own and by almost none with large fleets. As a result, the convention is in force, but the main centres of shipping are elsewhere. A shipment to or from a country that applies the Hamburg Rules raises a real question of which law applies, and that is the main reason to know the regime exists.

The Rotterdam Rules were more ambitious. They cover the whole journey from door to door rather than only from loading to discharge, they deal with electronic transport records, and they allow large volume contracts to depart from the rules within limits. This wide scope may be why so few countries have ratified them: a longer and newer convention gives every country more to object to. Whatever the reason, the status table above shows the result.

For anyone fixing ships today, the practical position is simple. Assume Hague-Visby by default. Trade with the United States uses a different figure. The clause paramount is the tool that brings the Rules in. And what ends most cargo claims is the one-year time bar, not an argument about who was right.
