Courier Liability Caps and Insuring a Research Shipment

If a research consignment is lost or damaged in transit, what will the carrier pay by default, why is it a per-kilogram figure, and when is declared-value cover worth buying?

When an international parcel is lost or damaged, the carrier's liability is set by a convention and by its own terms, and in both the unit of account is the kilogram. A parcel that weighs half a kilogram and contains material worth several thousand euros will, by default, be compensated as a half-kilogram parcel. The default is usually far below the invoice.

That does not make the carrier careless or the system unfair. It reflects what the system was built for: bulk freight, where weight and value are roughly proportional. Research consignments are the opposite case, light and valuable, and a buyer who knows this in advance can choose between three options: accept the cap, declare a higher value, or insure separately.

Why liability is per kilogram

Carriage conventions trade a certain, modest, quickly payable sum for the carrier against the claimant's freedom to sue for whatever the goods were worth. A carrier that can predict the maximum cost of a loss can price the service at a rate ordinary shippers can pay. A claimant who wants more can say so in advance, and pay for it.

The unit is the Special Drawing Right, an international reserve asset whose value is calculated from a basket of currencies. Its value in a national currency moves daily. A cap expressed in SDR per kilogram therefore has no fixed local-currency figure, and the carrier converts at the rate on a date its terms specify.

Air: the Montreal Convention cap and its revision

For international carriage by air, the governing instrument in most African states is the Montreal Convention of 1999. Article 22(3) limits the carrier's liability for destruction, loss, damage or delay of cargo to a figure per kilogram. In the text as enacted that figure is 17 Special Drawing Rights per kilogram. The same paragraph lets the consignor make a special declaration of interest in delivery at destination, and pay a supplementary sum if required, which raises the limit to the declared amount ^[1].

The number in the text is not the number in force. The Convention provides for the limits to be reviewed at intervals, and the International Civil Aviation Organization has revised them: the cargo figure rose to 19 SDR per kilogram in 2009 and to 22 SDR per kilogram with effect from 28 December 2019. A page that quotes a single figure without a date is out of date or is quoting a particular carrier's terms. Check the current figure with the carrier, and check whether the states of dispatch and of destination are parties to the Convention.

The Convention also sets time limits for complaints. For damage to cargo, the recipient must complain forthwith after discovery, and in any case within fourteen days of receipt. For delay, the complaint must be made within twenty-one days from the date the cargo was placed at the recipient's disposal. Both complaints must be in writing ^[1].

Carriers' own terms

Express carriers publish their own conditions of carriage and these apply by contract on top of, or in place of, a convention. One such set of terms, published by DHL Express for its Vietnamese service, states a limit for air shipments of 26 Special Drawing Rights per kilogram, or the current market or declared value if lower, and a limit of 8.33 Special Drawing Rights per kilogram for cross-border road carriage ^[2]. Those are one carrier's published figures for one country's service. The terms printed on your own airway bill, or published for your country, govern your shipment.

The same terms require a claim to be submitted in writing within thirty days of the carrier accepting the shipment, and allow only one claim per shipment ^[2]. Thirty days from acceptance is shorter than it sounds: a parcel that is slow to arrive and then found damaged can reach the end of the claim window before anyone opens it. Diary the date on dispatch.

Road: the CMR figure and national law

For international road carriage, a convention known as the CMR sets a limit of 8.33 SDR per kilogram, and the carrier's terms above repeat that figure for cross-border road carriage ^[2]. The CMR is a European convention with a small number of non-European parties. Whether it applies to a consignment moving between two African states depends on whether both are parties to it, and for most African routes that should be confirmed, not assumed. In its absence the carriage is governed by national road transport law or the haulier's contract. For overland routes, ask the haulier which terms apply and in what document they are written.

What is excluded

The Convention makes the air carrier liable for damage caused by delay unless it proves it took all reasonable measures ^[1]. Express carriers' conditions often go further in the other direction. The DHL terms cited above state that it is not liable for damage or loss caused by delay, while offering a money-back guarantee on some services, and that all other types of loss or damage, meaning consequential loss, are excluded ^[2]. Direct loss of the goods is what is compensated.

For a research buyer the exclusion that matters is the quiet one. A parcel that arrives intact but has been held for days in a depot, or exposed to heat, has not been lost. It has been delayed, and a delay claim, where it exists at all, does not cover the value of goods that cannot now be used. Whether goods are still usable after a warm delay is a question for the supplier and the laboratory, discussed on the information site under what happens if a peptide gets warm. It is outside what a carrier compensates.

Declared value and shipment insurance

The Convention allows a special declaration of interest in delivery; carriers offer an equivalent they call declared value or value protection. DHL describes a Shipment Value Protection service for its South African customers ^[3], and its general terms say it may be able to arrange shipment protection covering the full value of the goods if the shipper instructs it in writing and pays the charge, and that the protection does not cover indirect loss or loss caused by delays ^[2]. Other carriers have comparable products under different names.

Independent insurance is the alternative. A cargo insurer writes a policy against the consignment's value, with its own exclusions, its own conditions on packing and its own claims procedure. It can be cheaper or dearer than the carrier's product. It also separates the claim against the insurer from the claim against the carrier, which can make recovery slower but more complete.

1. Work out the invoice value of the consignment and divide by its weight in kilograms to see the value per kilogram.
2. Compare that with the carrier's cap for your route. If the value per kilogram is many times the cap, the default will not cover the loss.
3. Ask the supplier whether the quoted price includes cover and whom it protects.
4. Read the exclusions in writing. Note delay, indirect loss and packaging conditions.
5. Record the dispatch date, the claim deadline and the person who will file.

Filing a claim

Photograph the outer packaging before opening it. Keep the packaging. Write down the time of receipt and the condition on delivery, and note any damage on the carrier's delivery record when you sign, if the courier will allow it. Then send a written notice, which keeps the Convention's deadline and any shorter contractual one ^[1][2].

Include the airway bill number, the commercial invoice, the packing list, the photographs and the delivery record. Make one claim, listing everything, because the carrier's terms allow only one per shipment ^[2].

Who should buy cover

There is no universal answer. Who bears the risk of loss in transit depends on the sale terms agreed between buyer and supplier. Some suppliers bear it until delivery and include cover in the price. Others transfer it to the buyer at dispatch. The buyer should find out which applies before paying, and write it into the purchase order.

If the supplier bears the risk, ask what cover it holds. If the buyer bears it, compare the cost of cover with the cost of replacing the consignment and the time that would take. If neither wants to pay, the default is the carrier's cap, and both should know what that figure is.
