What Is a CMR Consignment Note? A Complete Guide to International Road Transport Documents

The CMR consignment note is one of the most important documents in international road transport. It records the details of the goods, the sender, the consignee, the carrier, and the conditions of carriage, and it defines the contractual relationship between sender and carrier. The CMR Convention itself was drawn up in 1956 to create uniform rules for international road carriage contracts and to define the carrier’s responsibilities. For anyone organizing cargo transport in Iran by road, or moving goods across Iran’s borders, understanding this document is a practical necessity, not a formality.

What Does CMR Stand For?

CMR comes from the French title of the convention, Convention relative au contrat de transport international de marchandises par route, meaning the Convention on the Contract for the International Carriage of Goods by Road. In everyday use, “CMR” refers both to the convention and to the road consignment note issued under it. The note records the key details of the shipment and the carriage contract on a standardized form.

What Is a CMR Consignment Note Used For?

A CMR note typically serves to:

• Record the sender’s details and identify the carrier

• Record the consignee’s details and state the place of taking over and the place of delivery

• Describe the goods: number of packages, weight or quantity, and type of packing

• Record freight charges and related instructions

• Support checks at borders and during customs clearance in Iran and in neighboring countries

• Document the international carriage contract itself

Customs authorities and other control bodies may also use the information on the CMR note to verify the goods, the sender, the consignee, and the carrier.

What Information Appears on a CMR Note?

Under the CMR Convention, the consignment note must contain specific information:

Sender: The name and address of the person or company handing over the goods for carriage.

Carrier: The name and address of the company or person responsible for the carriage.

Consignee: The name and address of the party to whom the goods must be delivered.

Place of taking over and place of delivery: Where the goods are collected and where they are to be delivered.

Description of the goods: The nature of the goods, number of packages, marks and numbers on the packages, and gross weight or quantity. For dangerous goods, the nature of the hazard must be stated in line with the applicable requirements.

Freight charges: The carriage charges and certain related costs.

Customs instructions: Where needed, instructions relating to customs formalities and other related matters.

The Carrier’s Liability Limit: A Figure That Is Often Far Below the Value of the Goods

One point cargo owners often overlook is that a carrier’s financial liability under the CMR Convention is not calculated on the real value of the goods. It is capped by weight. Compensation for loss or damage is limited to 8.33 Special Drawing Rights (SDR) per kilogram of gross weight of the goods lost or damaged. For many lightweight but valuable shipments, such as electronic components or precision equipment, this covers only a small fraction of their real commercial value. As an illustration, the total loss of a 10-tonne consignment would be compensated at a maximum of 83,300 SDR, which can be far below its actual commercial value.

This cap is lifted in only two situations. First, if the sender formally declares a value for the goods on the consignment note and pays the supplementary charge. Second, if the carrier’s wilful misconduct, or fault considered equivalent to it, is proven, in which case the limit no longer applies. This is why relying only on the carrier’s legal liability under CMR is not a substitute for independent cargo insurance. The two are different layers of protection and should be considered together for any shipment involved in cargo transit in Iran or beyond.

Reservations and Claim Deadlines

The CMR Convention sets short, strict deadlines for objecting to the condition of the goods, and missing them can cost you the right to claim. They differ depending on the type of problem:

• Apparent loss or damage: reservations must be made no later than the time of delivery.

• Non-apparent loss or damage: reservations must be made in writing within seven days of delivery, Sundays and public holidays excepted.

• Delay in delivery: no compensation is payable unless a written reservation is sent to the carrier within twenty-one days from the time the goods were placed at the consignee’s disposal.

If the consignee takes delivery without making the required reservations, this is treated as prima facie evidence that the goods were received in the condition described in the consignment note. Separately, the general limitation period for legal action is one year from delivery, extended to three years in cases of wilful misconduct.

How Many Copies Does a CMR Note Have?

Under the convention, the consignment note is made out in three original copies signed by the sender and the carrier. The first copy stays with the sender, the second travels with the goods, and the third is retained by the carrier. Depending on the operation, additional copies may be prepared for border and customs use.

When Is a CMR Note Used?

The CMR applies to international carriage of goods by road, meaning the place of taking over and the place of delivery are in two different countries and the conditions for applying the convention are met. In practice, it is a central document for land exports, land imports, cargo transit in Iran and through neighboring countries, shipments to neighboring states, road freight to Central Asia, and road freight toward Europe.

CMR vs. a Domestic Consignment Note

A CMR note is designed for international road carriage and issued within the framework of the CMR Convention. Domestic consignment notes, by contrast, are issued under the national transport rules of each country. A CMR note should therefore not be seen as just an international version of a domestic waybill. It is part of a legal and contractual framework that independently sets the liability limit, the claim deadlines, and the way damage claims are handled.

Why Accuracy Matters When Completing a CMR Note

The information on the CMR note must match the commercial and shipping documents: sender and consignee names, places of taking over and delivery, description of goods, number of packages, weight, marks and numbers, carriage details, and customs instructions. Under the convention, the sender is liable for certain costs, damage, and problems resulting from incorrect or insufficient information supplied. Discrepancies are also among the most common reasons for holds during customs clearance in Iran and at neighboring borders.

What Is e-CMR?

With the growth of electronic commerce, an electronic version of the consignment note, known as e-CMR, has been introduced. The additional protocol on e-CMR was adopted in 2008 and entered into force in 2011, allowing an electronic consignment note to be used between countries that have acceded to it. e-CMR can reduce paper documents, speed up information exchange, and give the parties in the transport chain better access to shipment data. In recent years, more countries have joined the protocol.

Why CMR Matters for Exports

In land exports, goods travel from the country of origin to the destination and may cross several borders on the way. Accurate, consistent shipping documents matter a great deal in this situation. The CMR note presents the main details of the shipment and the parties to the carriage in a standard format. That is why correctly completing the CMR, and understanding the liability cap and the claim deadlines, should be part of planning any export shipment by road from Iran.

Practical Tips on the CMR Consignment Note

• Check the goods before signing the delivery receipt. Signing without reservations is treated as prima facie evidence that the goods were received in good condition.

• If you see visible damage, record your reservation on the delivery document at that moment, not after the driver has left.

• For damage that is not apparent, send a written reservation within seven days of delivery (excluding Sundays and public holidays).

• For delay claims, remember the separate 21-day written reservation deadline.

• For valuable, lightweight goods, ask the carrier about declaring the value of the goods on the consignment note and paying the supplementary charge, because the default liability cap is based on weight, not value.

• Do not rely on the carrier’s legal liability alone. For full coverage of the goods’ value, arrange independent cargo insurance.

Frequently Asked Questions About the CMR Consignment Note

What happens if damage is not visible at the time of delivery?

The consignee must send a written reservation to the carrier within seven days of delivery (Sundays and public holidays excepted). Taking delivery without any reservation is treated as prima facie evidence that the goods were received in the condition described in the consignment note.

Does the carrier’s CMR liability cover the full value of the goods?

Usually not. Liability is capped at 8.33 SDR per kilogram of gross weight, not the real value of the goods. For fuller protection, the sender should declare the value of the goods or arrange separate cargo insurance.

What is the main difference between CMR and e-CMR?

CMR is the traditional paper consignment note, while e-CMR is its electronic equivalent under an additional protocol, allowing digital exchange and authentication of the document between participating countries.

The CMR consignment note is one of the most important documents in international road transport. It records the details of sender, consignee, carrier, goods, and conditions of carriage, and it sits alongside the convention’s rules on carrier liability and claim deadlines. For exporters, importers, carriers, drivers, and anyone moving cargo through cargo transport in Iran or through its border crossings, a clear understanding of the CMR note can prevent costly disputes.
