Multimodal Transport Document vs Ocean B/L: Liability Gap

Your shipping line arranged the trucking. They quoted the price. Their name is on the bill of lading. Then your cargo gets damaged on the truck — and they say it's not their responsibility.

In many cases, they're right. The difference comes down to which transport document you're holding: an ocean bill of lading or a multimodal transport document. This guide explains what each one covers, where carrier liability starts and ends, and how to tell them apart.

What is the difference between an ocean bill of lading and a multimodal transport document?

An ocean bill of lading covers port-to-port carriage only. The carrier's responsibility begins when cargo is loaded onto the vessel and ends when it's discharged at the destination port. Under the Hague-Visby Rules, this is known as "tackle to tackle" coverage — the period from when the ship's equipment first engages the cargo at loading to when it releases the cargo at discharge.

A multimodal transport document covers door-to-door carriage. According to the UNCTAD/ICC Rules for Multimodal Transport Documents, the Multimodal Transport Operator (MTO) assumes contractual responsibility for the entire journey, regardless of how many transport modes are involved — truck, rail, vessel, or air.

The key distinction is not the form of the document. It's the scope of liability. One covers the sea leg. The other covers everything.

Why does the same shipping line issue both documents on the same form?

Most shipping lines use a single bill of lading form for both port-to-port and multimodal shipments. According to trade documentation experts at LCViews, the form itself doesn't change — the fields filled in on the form determine whether it functions as an ocean B/L or a multimodal transport document.

This creates a practical problem. Shippers often assume that because the shipping line's name and logo appear on the document, the line is responsible for the entire journey. That assumption is wrong when the document is a port-to-port ocean B/L.

As stated in the terms and conditions of several major shipping lines, when the carrier arranges pre-carriage or on-carriage beyond the port, the carrier acts as "the Merchant's Agent only" and is not liable for loss or damage during those inland legs.

What happens when cargo is damaged on the inland leg?

The outcome depends entirely on which document you hold.

Scenario: Your cargo is damaged on the truck between the factory and the port of loading.

• Ocean B/L (port to port): The shipping line has no liability. The damage occurred outside the port-to-port coverage. You must pursue a claim against the trucking company directly. Under the Hague-Visby Rules, the carrier's liability does not extend to periods before loading or after discharge.

• Multimodal transport document (door to door): The MTO is liable. Under the UNCTAD/ICC Rules, the operator is responsible for loss or damage from the moment the goods are taken in charge until delivery at the final destination.

Same cargo. Same truck. Same damage. Different document, different outcome.

How do you tell which document you have?

Since both documents often use the same printed form, the title alone is not reliable. According to UCP 600 documentation guidelines, what matters is the content of the fields, not the title of the document.

Check two fields on the face of your B/L:

• "Place of Receipt" — where the carrier first takes charge of the goods

• "Place of Delivery" — where the carrier delivers the goods at destination

If both fields are blank or show the same location as the port of loading and port of discharge, the document covers port-to-port carriage only. Carrier liability is limited to the sea voyage.

If either field shows an inland location — a factory address, a warehouse, an ICD (Inland Container Depot) — the carrier has taken responsibility beyond the port. The document functions as a multimodal transport document, and the carrier's liability extends door to door.

What about liability limits and applicable laws?

When cargo is damaged under a multimodal transport document, the applicable liability regime depends on where the damage occurred. This is known as the network liability system.

• Sea leg: Hague-Visby Rules apply. Carrier liability is limited to approximately 667.67 SDR per package or 2 SDR per kilogram, whichever is higher.

• Road leg: The CMR Convention applies in most international road transports. Different liability limits apply.

• If the damage location is unknown: The sea carriage rules typically apply by default under most multimodal B/L terms.

For ocean B/L shipments involving the United States, COGSA (Carriage of Goods by Sea Act) limits carrier liability to $500 per package unless the shipper declares a higher value on the B/L and pays an additional freight charge.

In either case, carrier liability limits rarely cover the full value of the cargo. According to industry practice, most shippers purchase separate cargo insurance regardless of which transport document they hold.

What should you check before shipping?

• Confirm whether your B/L is port-to-port or door-to-door by checking "Place of Receipt" and "Place of Delivery"

• If port-to-port, arrange separate contracts and insurance for the inland legs

• If door-to-door, verify the carrier's terms for inland liability — some multimodal B/Ls still limit inland responsibility

• Read the B/L terms and conditions, specifically clauses about pre-carriage and on-carriage liability

• Consider cargo insurance for the full value, regardless of document type — carrier liability limits are low
