Delay in Cargo Transportation
Under Iranian law, a delay in transportation occurs when the carrier fails to deliver the cargo within the agreed time. Article 386 of the Iranian Commercial Code obligates the carrier to deliver the goods to the destination within the specified time. If it fails to do so, it will be liable for losses arising from the delay. This liability applies where the delivery time is expressly stated in the contract or can be determined by prevailing trade practice.
In addition, Article 227 of the Iranian Civil Code conditions contractual liability on the possibility of performance and on the absence of force majeure. Therefore, if the delay results from events beyond the carrier’s control, such as natural disasters or war, the carrier may be exempt from liability. However, where the delay is attributable to the carrier’s own fault or to the actions or omissions of its employees or agents, the carrier will be responsible for compensating the resulting damages. This framework provides the legal basis for assessing disputes arising from delayed delivery.
Conditions for Establishing the Carrier’s Liability for Delay
For a transportation company to be held liable for delay, certain conditions must be met. First, a valid contract of carriage must exist between the parties. Second, the delivery time must be specified either in the contract or by established trade custom. Third, the delay must have occurred without a justified and provable reason. The injured party must also prove that it suffered damages as a result of the delay.
Pursuant to Article 515 of the Civil Procedure Code, the claimant must specify the amount of damages claimed and support the claim with evidence. If the carrier can prove that the delay was caused by factors such as adverse weather, force majeure events, or legal impediments beyond its control, it will not be liable. Otherwise, the carrier may be required to compensate both direct and, where legally recognized, indirect losses arising from the delay. These requirements are intended to ensure that liability is determined on a fair and evidence-based basis.
The Role of the Contract of Carriage in Proving Liability for Delay
The contract of carriage is the primary document for determining liability for delay. It typically specifies the delivery timeline, the method of transport, cargo handling and storage conditions, and insurance arrangements. Under Article 388 of the Commercial Code, where a written contract exists and the delivery time is clearly stated, the carrier is required to comply with that term. If the delivery time is not stated, the burden may fall on the interested party to prove the applicable customary delivery time.
The contract may also include provisions addressing delay damages, such as a liquidated damages clause payable for late delivery. Where such a clause exists, courts commonly rely on it when issuing judgments. For this reason, both carriers and customers should clearly state the delivery time and delay-related terms in the contract, so that, in the event of a dispute, the competent authority can identify responsibility with clarity.

Damages Arising from Delay and How They Are Calculated
Damages resulting from delay may include direct losses such as a reduction in the value of goods, the loss of a sales opportunity, or contractual penalties owed to third parties. In assessing damages, courts typically rely on expert opinions and the documents submitted by the cargo owner. Article 221 of the Civil Code provides that the breaching party must compensate damages arising from non-performance, provided that the damages are direct and foreseeable.
In certain cases, indirect damages, including harm to commercial reputation, may also be considered if properly substantiated. If the contract specifies liquidated damages, the court may apply the agreed amount without recalculating. Depending on the circumstances, courts may also consider current market pricing, including commodity exchange reports, to estimate losses.

Legal Exceptions to the Carrier’s Liability for Delay
Iranian commercial and civil law recognize exceptions that may relieve a carrier from liability where the required conditions are met. The most significant exception is force majeure, namely events such as floods, earthquakes, war, or widespread strikes that occur beyond the carrier’s control. In addition, if the origin or destination is closed due to security measures or legal restrictions, the carrier may not be liable.
Delays caused by the cargo owner, including late loading, unilateral route changes without prior notice, or deficiencies in required documentation, may also fall outside the carrier’s liability. The carrier must, however, prove that such circumstances occurred. Judicial practice generally places the burden of proving force majeure on the carrier, and general or unsupported assertions may not be sufficient to exclude liability.
Legal Remedies for Delay in Cargo Delivery
Where delay is established and damages have occurred, the law provides remedies to protect the cargo owner. The primary remedy is a civil claim seeking compensation for material and, where applicable, non-material damages. Another remedy is termination of the contract, where a termination right has been stipulated due to delay. A further remedy is the enforcement of a liquidated damages clause when agreed in the contract. In addition, where the cargo is insured, the injured party may pursue compensation from the insurer, subject to the policy terms.
Certain transport companies may also face industry-related sanctions, such as fines or suspension, under relevant internal or sector-specific regulations. These remedies aim to preserve a fair legal balance between the parties to a contract of carriage.

The Difference Between Domestic and International Transport Delays
In domestic transportation, Iranian laws, such as the Commercial Code, the Civil Code, and the relevant regulations of the national road transport authority, apply. In international transportation, however, international conventions, including the CMR, may govern the relationship. Under the CMR framework, the carrier’s liability is often defined more strictly, and in many cases, the carrier remains liable unless it proves a qualifying force majeure event.
In international transport, the CMR consignment note is the principal document evidencing the contract of carriage. Limitation periods and compensation caps may also differ from domestic rules. Accordingly, companies engaged in international transportation should maintain thorough knowledge of applicable transnational rules to manage exposure to significant liabilities.
The Role of Insurance in Compensating Delay-Related Losses
Cargo insurance can play an important role in mitigating financial losses from delays. Depending on the specific policy terms, a cargo insurance policy may cover delay-related losses only under particular conditions. In standard cargo insurance policies, delay is generally not covered unless an additional premium is paid and a specific endorsement is included. Carrier liability insurance may also cover some losses suffered by third parties, including the cargo owner, subject to the policy scope.
In any event, insurance does not eliminate the carrier’s underlying liability. Rather, it provides a financial mechanism for compensation. To obtain insurance compensation, the cargo owner typically must submit the carriage contract, invoices, a timely notice of the claim, and documents evidencing the delay and the resulting loss. Insurance, therefore, serves as a complementary risk management tool to reduce the consequences of delayed delivery.
Limitation Period for Filing Claims Related to Delay
Iranian law does not expressly set out a separate limitation period specifically for delay in transportation; however, under Article 388 of the Commercial Code, claims against the carrier must generally be brought within one year from the date of delivery or from the scheduled delivery date. After the expiry of this period, the claim may be inadmissible. This general rule covers claims involving delay, loss, damage, or non-delivery.
Similarly, under the CMR Convention, the time limit for bringing a claim is commonly one year. This period may be extended in certain situations, such as where a legal impediment exists or the parties have agreed, depending on the applicable framework. As a result, injured parties should act within the relevant time limits to avoid losing the right to seek compensation.
Legal Recommendations for Cargo Owners and Transportation Companies
To reduce disputes, cargo owners should enter into a written contract with reputable carriers. The contract should clearly specify the delivery time, the nature of the cargo, packaging requirements, insurance coverage, delay penalties, and a defined complaint procedure. It is also advisable to use an official consignment note.
On the carrier side, careful documentation of loading procedures, routes, communications, and any unexpected obstacles is essential for establishing an effective defense when needed. Accurate record keeping of timelines, road conditions, and incidents can be decisive in demonstrating an exemption from liability. In addition, appropriate insurance coverage and staff training on legal compliance can help protect the company against potential claims. Implementing these measures reduces risk and improves legal certainty for both parties.
Frequently Asked Questions About Delay in Cargo Transportation
A delay occurs when the carrier fails to deliver the cargo within the time specified in the contract or determined by applicable trade customs, and the delay results in loss to the cargo owner.
