Every year, cargo damage claims cost the global shipping industry billions of dollars. According to the latest data from the International Union of Marine Insurance (IUMI), cargo losses exceeded USD $9 billion in 2024 alone. While marine insurance provides essential protection, the operational disruption, delayed deliveries, and reputational damage that accompany cargo claims far exceed the immediate financial loss.
The good news? Most cargo damage is preventable. Through decades of surveying cargo across Asia Pacific, Singapore Marine Agency has identified clear patterns in how and why cargo gets damaged—and more importantly, what you can do to stop it before it happens.
Here are the five most common types of cargo damage claims we encounter, the prevention methods that work, and how SGMA’s independent surveys protect your interests at every stage.
1. Improper Stowage
What It Is
Improper stowage is the leading cause of cargo damage in containerized shipping. This occurs when cargo is incorrectly secured within a container, vessel hold, or on deck—leading to shifting, crushing, or collapse during transport. Common stowage errors include:
- Inadequate securing with insufficient lashings, dunnage, or bracing
- Overloading containers beyond safe weight limits
- Poor weight distribution creating imbalance
- Incompatible cargo stowed together (e.g., heavy machinery atop fragile goods)
- Failure to account for vessel motion during sea transit
Why It Happens
Stowage failures often stem from time pressure at loading terminals, lack of proper training, or cost-cutting measures that skip essential securing materials. In some cases, shippers underestimate the forces cargo will experience during a long ocean voyage—particularly in rough seas where containers can experience lateral acceleration exceeding 1G.
Prevention Methods
Before Loading:
- Engage a marine surveyor to review the stowage plan before cargo leaves the warehouse
- Ensure adequate securing materials (lashing straps, timber dunnage, airbags, blocking) are on hand
- Calculate the cargo’s centre of gravity and confirm compatibility with container specifications
- Review the vessel’s cargo securing manual (CSM) if shipping break-bulk
During Loading:
- Supervise loading operations with an experienced cargo surveyor present
- Photograph each stage of the stowage process for documentation
- Verify that lashing points are used correctly and securing equipment is rated for the cargo weight
- Conduct a final pre-departure inspection to confirm all fastenings are tight
SGMA Survey Checkpoints:
When you book a pre-shipment stowage inspection with Singapore Marine Agency, our surveyors verify:
- Cargo is secured to container/vessel structure per IMO/ISO standards
- Lashing tension is adequate and evenly distributed
- Dunnage placement prevents point-loading and cargo contact
- Weight distribution complies with container payload limits
- Photographic evidence is captured at each securing stage
Case in Point: In Q4 2025, SGMA conducted a pre-loading survey for a machinery shipment from Indonesia to Singapore. Our surveyor identified insufficient bracing that would have led to cargo shift during transit. The client implemented our recommendations, and the cargo arrived undamaged—avoiding a potential USD $180,000 claim.
2. Moisture Damage
What It Is
Moisture damage (also known as wet damage) occurs when cargo that is moisture-sensitive, such as steel coils, electronics, food products, or paper goods, is exposed to water, condensation, or high humidity. This can result in rust, mold, spoilage, or electrical failure. Moisture ingress typically happens through:
- Container rain (condensation forming on the container roof and dripping onto cargo)
- Leaking hatch covers on bulk vessels
- Damaged or worn container door seals
- Exposure to rain during loading/unloading
- Insufficient desiccants or ventilation in the container
Common Scenarios
Container Rain: When a loaded container travels from a hot, humid climate (e.g., Southeast Asia) to a cooler region, moisture in the air condenses on the interior walls and ceiling. Without adequate moisture control, this water drips onto cargo, often going unnoticed until the container is opened at destination.
Hatch Cover Leaks: For cargo shipped in vessel holds (break-bulk or dry bulk), worn hatch cover rubber seals or damaged steel plating can allow seawater ingress during heavy weather. By the time the vessel arrives in port, the cargo may be substantially damaged.
Prevention
Pre-Loading Inspection:
- Inspect the container or hold interior for signs of previous water damage (rust streaks, staining)
- Check door seals and gaskets for cracks, tears, or deformation
- Verify that the container floor is dry and free from standing water
- Review hatch cover condition reports if shipping in vessel holds
Moisture Control:
- Install moisture-absorbent desiccants (calcium chloride or silica gel bags) inside the container, calculating the correct quantity based on cargo volume and voyage duration
- Use cargo blankets or moisture barriers to separate cargo from container walls
- Ensure adequate airflow by avoiding over-packing—leave 10-15cm gaps along walls for air circulation
- For high-value moisture-sensitive cargo, consider ventilated containers with airflow vents
During Transit:
- For long ocean voyages, request periodic container atmosphere monitoring if feasible
- On break-bulk vessels, request ultrasonic hatch cover testing (UHCT) before departure to detect seal leaks
Documentation:
- Take timestamped photos and humidity readings at the time of loading
- Note any pre-existing damage to the container or hold in the pre-loading survey report
How SGMA Helps:
Singapore Marine Agency’s container condition surveys thoroughly inspect containers before loading. Our surveyors use moisture meters to measure relative humidity inside the container and check all seals, floors, and walls for signs of leakage. We provide a detailed photographic report documenting the container’s pre-loading condition – critical evidence if a moisture damage claim arises.
3. Temperature-Related Damage
What It Is
Temperature-related damage affects refrigerated (reefer) cargo such as perishable food, pharmaceuticals, and chemicals that require climate-controlled transport. Damage occurs when:
- The reefer unit fails mid-voyage, causing cargo to spoil
- Temperature settings are incorrect for the cargo type
- Pre-cooling is insufficient before loading, starting the journey at the wrong temperature
- Warm ambient air enters the container during stuffing, raising the internal temperature
- Power supply issues at port cause prolonged shutdown of refrigeration
According to industry data, reefer claims account for approximately 15% of all cargo damage by value, with pharmaceuticals particularly vulnerable due to strict temperature validation requirements (typically ±2°C tolerance).
Common Causes of Reefer Failure
- Mechanical breakdown: Compressor failure, refrigerant leaks, or sensor malfunctions
- Incorrect temperature set point: E.g., setting a pharmaceutical load at +5°C when it requires +2 to +8°C
- Poor cargo stowage blocking airflow: Reefer containers rely on airflow around cargo; over-packing or improper stowage blocks circulation
- Electrical supply issues: Voltage fluctuations, plug disconnections, or generator failures on the vessel
- Insufficient pre-cooling: Loading cargo into a reefer that hasn’t reached the target temperature
Monitoring Requirements
Modern reefer containers are equipped with data loggers that record internal temperature throughout the voyage. However, these logs are only useful if reviewed promptly. Many cargo damage claims occur because shippers fail to:
- Request the temperature log at destination
- Verify that the reefer unit maintained the target temperature throughout transit
- Respond to temperature excursions during the voyage (if real-time monitoring is available)
Prevention
Before Loading:
- Pre-cool the reefer container to the target temperature at least 6 hours before cargo loading
- Verify that the reefer unit is functioning correctly by running a pre-trip inspection (PTI) test
- Confirm that the temperature setpoint matches the cargo’s requirements (refer to the manufacturer’s storage guidelines)
- Check that ventilation settings are correct, some cargo requires fresh air exchange (e.g., bananas produce ethylene gas), while others need sealed environments
During Stuffing:
- Minimize the time the reefer doors are open to prevent warm air ingress – ideally, load cargo within 30 minutes
- Ensure cargo is stowed with adequate airflow gaps – do not stack cargo flush against walls or the T-shaped floor decking
- Use load-bearing pallets to allow airflow beneath the cargo
- Do not exceed the reefer’s maximum payload capacity, as overloading reduces cooling efficiency
Survey Procedures:
Pre-Shipment Reefer Inspection by SGMA:
- Verify the reefer unit passes a full PTI test (compressor operation, temperature accuracy, alarm functionality)
- Check that the cargo thermometer matches the reefer unit’s displayed temperature
- Inspect the container interior for cleanliness (previous cargo residue can cause contamination)
- Photograph the cargo at loading with timestamps showing date, time, and initial temperature
- Provide a written report confirming the reefer was fit for the voyage
On-Arrival Survey:
If temperature excursion is suspected, SGMA conducts an immediate on-arrival survey to:
- Download the reefer unit’s data logger and generate a temperature graph
- Compare logged temperatures against the required range
- Inspect cargo for signs of thawing, spoilage, condensation, or discoloration
- Secure samples if required for laboratory testing (e.g., pharmaceuticals)
Case Study: In January 2026, SGMA was engaged by a meat supplier shipper to survey a reefer container carrying frozen meat from Brazil to Singapore. Upon arrival, our surveyor downloaded the data logger and identified a 4-hour temperature excursion to +12°C (outside the required range of -18°C to -25°C) during the voyage. The reefer unit had experienced a compressor failure that went unnoticed. Thanks to our survey evidence and the data log, the shipper’s insurance claim was settled without any issues, and the compromised frozen meat were not released to the market – preventing a potential public health issue.
4. Contamination
What It Is
Contamination occurs when cargo comes into contact with foreign substances that render it unfit for use, unsafe, or commercially unacceptable. Common contaminants include:
- Odor contamination: Previous cargo (e.g., fish, chemicals, tobacco) leaves residual odors that permeate into sensitive goods like coffee, tea, or cocoa
- Physical contamination: Dust, rust, oil, or cargo residue from prior shipments mixes with the current cargo
- Chemical contamination: Leaking containers or incompatible cargo stowed nearby release vapors or liquids that contaminate adjacent cargo
- Pest contamination: Insects, rodents, or microorganisms in the container or hold infest the cargo
Contamination claims are particularly damaging because they often affect the entire cargo lot, not just isolated packages. In food-grade shipments, even minor contamination can lead to a total rejection by the buyer.
Sources of Contamination
Container History: Containers are used for a wide variety of cargo types. A reefer that previously carried fish may retain odors even after cleaning, contaminating a subsequent load of fresh fruit. Similarly, a dry container used for chemicals may have residue on walls that contaminates bagged cargo.
Incompatible Cargo Stowage: When cargo with strong odors or volatile emissions (e.g., rubber, chemicals, onions) is stowed near odor-sensitive cargo, cross-contamination can occur—even through sealed packaging.
Pest Infestation: Cargo loaded from warehouses with poor pest control can introduce insects or rodents into containers. Some jurisdictions (e.g., Australia, New Zealand) impose strict quarantine rules, and infested cargo may be fumigated, destroyed, or rejected at the border.
Pre-Loading Inspections
The most effective way to prevent contamination is through rigorous pre-loading container inspections:
Visual Inspection:
- Inspect the container interior for residue, stains, rust, or foreign matter
- Smell the interior—even faint odors can contaminate cargo during a 2-3 week ocean voyage
- Check for pest entry points (holes, cracks, damaged door seals)
- Verify cleanliness standards for food-grade cargo (ISO 22000, BRC standards if applicable)
Cleanliness Certification:
For food-grade or pharmaceutical shipments, request a container cleanliness certificate from the container depot. If the container does not meet standards, reject it and request a replacement.
Documentation
If contamination is discovered at destination, immediate documentation is critical:
- Photograph the contaminated cargo and container interior from multiple angles
- Secure samples of the contaminant (e.g., collect residue from container walls, capture live insects in a sealed container)
- Note the container number, seal number, and previous cargo history (available via the container operator’s booking system)
- Obtain an independent survey report from a qualified marine surveyor
SGMA’s Contamination Survey Services:
When contamination is suspected, Singapore Marine Agency provides:
- On-site inspection within hours of discovery to preserve evidence
- Laboratory sample coordination if required (e.g., chemical analysis, microbiology testing)
- Container history research to identify the source of contamination
- Detailed photographic evidence and written survey reports accepted by insurers and cargo receivers worldwide
Our surveyors are trained in HACCP principles and food safety standards, ensuring that contamination surveys meet the documentation standards required for insurance claims and legal proceedings.
5. Physical Impact Damage
What It Is
Physical impact damage includes crushing, denting, tearing, or breakage caused by rough handling during loading, transit, or discharge. Common scenarios include:
- Cargo dropped from lifting equipment (forklifts, cranes, ship’s gear)
- Containers struck by terminal equipment or other containers
- Palletized cargo crushed when stacked too high or on unstable surfaces
- Fragile cargo damaged due to insufficient cushioning or packaging
- Rolling or sliding during vessel movement in heavy seas
Physical impact is often visible immediately and is one of the easier types of damage to prevent—but only if proper handling procedures are enforced.
Why It Happens
Operator Error: Inexperienced or fatigued equipment operators may mishandle cargo, particularly at congested terminals where time pressure is high.
Inadequate Packaging: Shippers sometimes under-package cargo to save costs, using insufficient padding, weak pallets, or under-spec crating. While the cargo may survive the warehouse, it often fails to withstand the rigors of ocean transport.
Terminal Congestion: At busy ports like Singapore, containers are frequently shifted multiple times before loading. Each move introduces the risk of impact damage, especially if handled hastily.
Handling Procedures
Proper Lifting Techniques:
- Use certified lifting gear (slings, spreader bars, hooks) rated for the cargo weight
- Employ professional rigging teams for oversized or heavy cargo
- Avoid side-loading fragile cargo – lift vertically whenever possible
- Never use cargo hooks on packaged goods unless specifically designed for hook lifting (e.g., steel coils)
Packaging Standards:
- Fragile items should be double-boxed with foam, bubble wrap, or inflatable airbags
- Pallets must be in good condition with no broken or cracked boards
- Use stretch wrap or strapping to secure cargo to pallets
- Mark all packages clearly with “FRAGILE” or “HANDLE WITH CARE” labels in multiple languages
Loading Supervision
The most effective way to prevent physical impact damage is to have a marine surveyor present during loading and discharge:
Pre-Loading Survey:
Before cargo is handled, SGMA surveyors:
- Inspect all packaging for pre-existing damage
- Verify that the cargo is ready for transport (properly secured, adequately packaged)
- Photograph the cargo condition before any movement
During Loading:
Our surveyors:
- Monitor lifting operations to ensure safe handling
- Identify and stop any unsafe practices (e.g., cargo swinging freely on crane hooks)
- Document each stage with photographs
- Communicate with terminal operators to correct any issues in real-time
Post-Loading/Pre-Departure Survey:
After loading is complete:
- Verify that cargo is properly stowed and secured in the container or vessel hold
- Confirm that no damage occurred during loading
- Seal the container and photograph the seal number for later verification
Damage Documentation
If damage occurs despite precautions, immediate documentation is essential:
- Stop handling operations immediately
- Photograph the damaged cargo from multiple angles
- Document the exact time, location, and handling equipment involved
- Obtain witness statements from terminal staff if possible
- Engage a marine surveyor to prepare a formal damage survey report
