Damage Due to the Inherent Nature of Cargo
Interlink編集部Overview
Damage caused by inherent properties of the cargo refers to damage such as breakage, deterioration, leakage, weight loss, rust, spoilage, mold, and degradation that occur due to the characteristics of the cargo itself rather than external incidents during transportation or the handling by the carrier.
In international transport, cargo is subjected to factors such as long transit times, changes in temperature and humidity, vibration, transshipment, storage, and condensation inside containers. If the cargo itself has properties such as being sensitive to moisture, prone to oxidation, easy to leak liquids, liable to spoilage, naturally losing weight, or susceptible to time-related degradation, then damage caused by these inherent properties becomes a problem.
In such cases, even if the cargo is damaged, it does not necessarily mean the carrier, NVOCC, or freight forwarder is immediately liable for compensation. In actual logistics practice, it is necessary to separate and verify the relationships between external incidents, inadequate packing, inherent cargo properties, insurance exclusions, and subrogation claims.

Why Are Inherent Cargo Properties an Issue?
In cargo incidents, damage is often discovered during transit, leading shippers or insurers to claim that "since the damage occurred during transportation, the carrier is responsible." However, the fact that damage was discovered during transportation and the fact that it was caused by the carrier’s responsibility are separate matters.
If the cargo itself is sensitive to moisture, temperature, oxidation, vibration, or the passage of time, rust, spoilage, deterioration, leakage, weight loss, or quality degradation may occur even without any special external incidents. Such damage may be categorized as caused by the inherent properties of the cargo, not by the carrier’s handling.
However, not all claims can be denied solely because of inherent cargo properties. If there are external incidents such as seawater wetting, container damage, reefer power failure, abnormal temperature deviations, or rough handling, these should be considered as carrier liability or insurance events. In practice, it is necessary to separate and confirm through documentation whether the damage is usually caused only by the cargo’s properties or triggered by an external incident.
Common Misunderstandings
| Common Misunderstanding | Correct Understanding | Practical Cautions |
|---|---|---|
| If damage occurred during transportation, it is the carrier’s responsibility | Even if damage is discovered during transportation, if caused by the cargo's inherent properties, carrier exemption becomes an issue | Confirm the cause of damage, not just the timing of discovery |
| If it is an inherent property, insurance will not cover it | Insurance coverage is determined by policy terms, presence of external incidents, and exclusions | Separate insurance payments from carrier liability |
| Usual leakage can be included in the damage amount | Leakage or weight loss normally caused by the cargo’s nature may be excluded from claims | Distinguish normal range from abnormal range |
| If there is rust or spoilage, it must be an external incident | Rust and spoilage can also occur due to moisture, temperature, cargo condition, and inadequate moisture-proofing | Check salt reactions, temperature and humidity records, packing status |
| If a survey shows the damage amount, responsibility is also determined | Damage amount confirmation and determination of liability are separate issues | Review cause description in the survey report |
Classification by Damage Type

Distinction from Poor Packing
The inherent nature of the cargo and poor packaging often overlap as issues in actual logistics practice. The inherent nature of the cargo refers to problems arising from the cargo’s own characteristics causing damage. On the other hand, poor packaging refers to insufficient protective measures, packing, securing, moisture-proofing, rust prevention, waterproofing, temperature control, etc., appropriate to those characteristics.
For example, the fact that metal products are prone to rusting is an inherent characteristic of the cargo itself. However, if anti-rust treatment, moisture-proof packaging, desiccants, and sealing are insufficient despite the cargo being prone to rust, poor packaging becomes an additional issue.
In such cases, carriers or insurance companies may claim exemption from liability based on both the cargo’s nature and poor packaging. For the shipper side to argue against this, it is necessary to provide documentation demonstrating that appropriate packaging, moisture control, and rust prevention measures were taken considering the cargo’s nature, or that an external accident was the cause of damage.
Normal Leakage, Normal Weight Loss, Natural Deterioration
Depending on the cargo, some degree of leakage, weight loss, or consumption may occur during transport. This is common with liquid cargo, powders, grains, minerals, chemicals, food raw materials, etc., where minor leakage, weight reduction, or volume reduction may naturally occur.
Such normal leakage, normal weight loss, and natural deterioration should be distinguished from damage caused by external accidents. Within the normal range, these are often excluded from claims or may raise issues of carrier exemption.
On the other hand, if there is significant leakage or weight loss beyond the normal range, it is necessary to check for other causes such as container damage, poor stowage, cargo handling accidents, inadequate temperature control, or theft. The key is to differentiate the range predictable due to the cargo’s nature from the range caused by abnormal accidents.

Cases Commonly Problematic in Practice
| Case | Issue | Points to Confirm | Practical Response |
|---|---|---|---|
| Metal products are rusting | The dispute centers on seawater wetting, condensation, or insufficient rust prevention | Salt reactions, rust-proof packaging, container condition | Check for evidence of external water exposure |
| Food is spoiled | The dispute concerns poor temperature control, natural deterioration, or condition before shipment | Temperature records, manufacture date, best-before date, pre-shipment inspection | Confirm timing when quality deterioration occurred |
| Liquid cargo is leaking | The issue is whether this is normal leakage, container defect, or external impact | Container specifications, leak location, exterior damage | Confirm whether leakage is within normal range |
| Weight discrepancy in powder cargo | It is necessary to separate normal weight loss, measurement differences, handling spillage, theft | Loading weight, discharge weight, weighing records, bag condition | Organize causes and scope of weight loss |
| Mold occurs due to condensation inside the container | The dispute involves cargo hygroscopicity, insufficient moisture-proof packaging, or external water exposure | Ceiling condensation, packaging moisture content, desiccants, salt reaction | Differentiates container sweat and external water exposure |
| Chemicals have separated or sedimented | The issues are temperature changes, elapsed time, component characteristics, contamination | SDS, product specifications, temperature records, test results | Confirm whether changes are normal due to cargo characteristics |
Specific Examples
Example 1: Rust Damage to Metal Parts
This case involved metal parts imported from Southeast Asia to Japan that showed rust damage. The shipper filed a claim alleging water damage during transit, but the container exterior showed no holes or damage, and no salt reaction was observed.
The survey found condensation marks on the container ceiling, high moisture content in the wooden pallets and cardboard packaging, and insufficient moisture-proof packing and desiccants. In this case, the main causes could be attributed to the cargo’s rust-prone nature, inadequate moisture protection, and container sweat rather than an external accident.
Example 2: Degradation of Refrigerated Food Quality
This case involved refrigerated food that showed quality deterioration at the import location. The shipper claimed temperature control failure during reefer transport, but reefer records showed no significant temperature deviations.
On the other hand, checking the manufacture date, expiration date, and pre-shipment storage conditions revealed that at the time of shipping, the shelf life was already short, and the cargo itself was vulnerable to quality deterioration over time. In this case, it is the cargo’s inherent characteristics and pre-shipment condition that become the issue, rather than the carrier’s temperature control failure.
Example 3: Leakage of Liquid Cargo
This case involved drum cargo of liquid chemicals, where partial leakage was confirmed upon arrival. There were no strong impact marks on the outer packaging, but a small amount of leakage was observed around the drum lid.
Upon investigation, container specifications, sealing conditions, expansion due to temperature changes, and the normal range of leakage were considered problematic. If no external impact or dropping incidents can be confirmed, this should not be immediately regarded as a carrier handling accident only, but rather assessed by considering the nature of the liquid cargo, container suitability, and sealing condition.
Relation to Marine Cargo Insurance and Subrogation Claims
Even if insurance compensation is paid under marine cargo insurance, this does not automatically establish liability of the carrier, NVOCC, or freight forwarder. Payment of insurance proceeds is a decision under the insurance contract and should be considered separately from the determination of carrier liability.
When subrogation claims are made by the insurance company, if the cause of damage is thought to lie in the inherent nature of the cargo, it is important to organize and review relevant information such as cargo characteristics, packing condition, temperature and humidity records, survey reports, and receipt descriptions to formulate a rebuttal.
In responding to subrogation claims, it is important not to simply accept the insurance payout amount as is, but to verify cause of the accident, exempting clauses, liability limits, notification deadlines, and statute of limitations, while reserving all rights and defenses.
Practical Points
Damage due to the inherent nature of the cargo is a critical exemption and rebuttal point in determining the liability of carriers, NVOCCs, and freight forwarders. Even if damage is discovered during transit, it is necessary to differentiate whether it was caused by an external accident or by the cargo’s own nature.
Especially with issues such as rust, spoilage, leakage, shortage, mold, deterioration, and quality decline, causes cannot be judged by appearance alone. It is necessary to verify through documentation whether there was external water damage, temperature deviation, container damage, or cargo handling accidents, or whether it arose from the cargo’s nature, insufficient moisture protection, pre-shipment condition, or normal wear and tear.
In actual logistics practice, it is important to organize cargo specifications, SDS, temperature and humidity records, packing specifications, receipts, survey reports, and Claim Letters, and before acknowledging liability, confirm the relationships among the cargo’s inherent nature, packing deficiencies, external accidents, insurance exemptions, and subrogation claims.
