Mold, Discoloration, Quality Deterioration Damages and Cargo Insurance

What Are Mold, Discoloration, and Quality Deterioration Damages?

Mold, discoloration, and quality deterioration damages refer to losses where cargo, during transportation or storage, is affected by moisture, temperature fluctuations, condensation, water exposure, contamination, passage of time, inadequate packaging, insufficient temperature and humidity control, or similar factors, resulting in mold growth, discoloration, deterioration, odor, component changes, quality degradation, or becoming unusable or unsellable.

For goods such as food, agricultural products, textiles, paper products, lumber, leather goods, chemicals, pharmaceuticals, cosmetics, resin products, metal products, and precision instruments, the product value may be lost due to quality changes even if the external packaging is not significantly damaged.

Marine cargo insurance does not determine coverage solely based on the occurrence of mold or discoloration.

The cause must be distinguished as to whether it was an accidental external event during transit, a natural change due to the inherent nature of the cargo, pre-existing quality defects before shipment, or inadequate preparation such as packaging, moisture-proofing, or temperature control.

In ICC 2009, normal leakage, ordinary weight loss, and ordinary wear and tear are excluded under Clause 4.2; insufficient or improper packing or preparation for transportation is excluded under Clause 4.3; and inherent vice or nature of the goods is excluded under Clause 4.4.

Additionally, if the container or transport equipment itself was unsuitable for safe carriage, the relationship with Clause 5.1.2 should also be checked.

Therefore, in quality deterioration incidents, it is important to separately verify the damage condition, cause, timing of occurrence, basic insurance terms, exclusion clauses, liability coverage, and extent of loss.

Exclusion Clauses in ICC 2009 and Quality Deterioration Damage

Clause	Main Content	Relation to Quality Deterioration Damage	Points for Practical Confirmation
Clause 4.2	Ordinary leakage, usual decrease in weight or volume, normal wear and tear	Issues such as normal drying, evaporation, shrinkage, and aging changes arise	Distinguish between normal loss specific to each cargo and abnormal accidental damage
Clause 4.3	Insufficient or improper packing or preparation unable to withstand ordinary transport risks	Lack of moisture protection, desiccants, light shielding, inner packaging, or securing is problematic	Confirm who packed, when, and according to what specifications
Clause 4.4	Defects or nature inherent to the cargo itself	Natural progression of moisture absorption, fermentation, decay, oxidation, discoloration, etc.	Confirm whether damage occurred without external accident
Clause 4.5	Delay damage, including if caused by insured risk	Concerns about spoilage, approaching expiration date, or quality degradation due to transport delay	Separate physical accidental damage from loss due to elapsed time
Clause 5.1.2	Containers or transport equipment unsuitable for safe carriage	Quality changes due to holes, faulty doors, inadequate cooling capacity, etc.	Confirm recognition of unsuitability and who loaded and when

Clauses 4.2, 4.3, and 4.4 are adjacent but are not the same exclusion.

It is necessary to separately examine normal shrinkage or wear, packing deficiencies as part of transport preparation, and the cargo’s inherent nature.

Why a Causal Relationship with an Accidental External Incident Is Required

Marine cargo insurance is fundamentally designed to cover damage that occurs accidentally during transportation or storage.

Changes such as spoilage, fermentation, oxidation, drying, and discoloration that naturally progress under normal transport conditions tend to be evaluated as changes inherent to the cargo itself, rather than damage caused by an unforeseeable accident.

Moreover, if necessary preparations for transport—such as packaging, moisture control, temperature setting, drying, or pre-cooling—were insufficient before shipment, the cause is likely considered to stem from the preparation phase prior to transport rather than an accidental incident during transit.

Therefore, for quality changes to be covered by cargo insurance, it is not enough that they were discovered during transport. A causal relationship between the quality change and an external accident occurring during transport or the insurance coverage period must be demonstrated.

Causal Relationship to Confirm	Conditions Likely Considered Insurable	Conditions Where Exclusion May Be Contested	Main Evidence
Accident’s Accidental Nature	Unexpected water ingress, leakage, cooling system failure, external contamination	Deterioration naturally progressing under normal conditions	Accident reports, equipment logs, container records
External Origin	Exposure to external water, oil, odors, heat, etc.	Changes caused solely by moisture, components, or microorganisms inside the cargo	Component analysis, moisture content, microbiological tests
Temporal Relationship	Rapid change occurring after a specific accident	Gradual progression starting from manufacturing or storage	Temperature history, quality inspections, chronological photos
Abnormality of Damage	Rapid or localized damage exceeding normal expectations	Wear or deterioration typical of cargo characteristics	Past records, acceptable standards, expert opinions
Pre-shipment Condition	Objective evidence showing the cargo was normal before shipment	Unknown pre-shipment quality or signs of abnormality	Pre-shipment inspection, quality certificates, photos

Cargo Commonly Problematic

Cargo Type	Typical Quality Changes	Main Possible Causes	Practical Points to Confirm
Food, Agricultural Products, Marine Products	Mold, spoilage, discoloration, odor, quality deterioration	Temperature, moisture content, microorganisms, delays, insufficient pre-cooling	Check temperature records, manufacturing date, expiration date, hygiene inspection
Clothing, Textile Products	Mold, color transfer, discoloration, odor	Humidity, condensation, dye transfer, insufficient moisture control	Confirm packaging, moisture-proof materials, humidity, dye fastness
Leather Products	Mold, hardening, discoloration, odor	High humidity, insufficient drying, residual chemicals	Verify manufacturing moisture content, storage conditions, packaging
Paper Products, Printed Materials	Warping, discoloration, mold, printing deterioration	Moisture absorption, water exposure, condensation, pallet moisture	Check paper moisture content, outer packaging, pallets, container interior
Wood, Furniture	Mold, warping, discoloration, cracking, insect damage	Insufficient drying, moisture content, humidity, temperature variation	Confirm moisture content, drying certificate, fumigation, pre-shipment condition
Chemicals, Resins, Rubber	Hardening, softening, discoloration, separation, component changes	Temperature, UV exposure, oxidation, container defects	Check SDS, storage temperature, component analysis, container condition
Pharmaceuticals, Cosmetics	Component changes, discoloration, odor, off-specification	Temperature deviation, light exposure, aging, inadequate sealing	Verify lot number, stability tests, temperature records, regulatory standards
Metal, Machinery Parts	Rust, corrosion, discoloration, oil film degradation	Condensation, salt contamination, water exposure, insufficient rust prevention	Inspect salt presence, rust prevention measures, packaging, environment at time of incident
Precision Equipment, Electronic Components	Corrosion, insulation decline, malfunction	Humidity, condensation, temperature fluctuations, static electricity	Check functional tests, humidity records, packaging specifications

Basic Four Classifications of Damage Causes

Category	Typical Examples	Viewpoint in Insurance	Main Documentation for Verification	Attribution of Responsibility
Accidental External Incidents	Container puncture, warehouse water leakage, unexpected temperature deviation, external contamination	Considered for coverage as accidental incidents during the insurance period	Accident photos, temperature records, survey reports, warehouse records	Check carrier, warehouse operator, trucking company, etc.
Inherent Nature of Cargo	Natural fermentation, spoilage, oxidation, moisture absorption, natural discoloration	Inherent Vice under Clause 4.4 is applicable	Specifications, ingredient lists, SDS, storage conditions, quality history	Confirm management by manufacturer, exporter, and cargo owner
Pre-Shipment Quality Deficiency	Mold present before shipment, high moisture content, insufficient drying or pre-cooling	Considered a condition existing before insurance coverage start	Pre-shipment inspection reports, lot numbers, production dates, moisture content, photos	Verify manufacturer, exporter, inspection agencies
Packing and Preparation Deficiencies	Insufficient desiccants, inadequate moisture barriers, insufficient light shielding, improper vanning	Application of Clause 4.3 is at issue	Packing specifications, photos, desiccant calculations, vanning records	Confirm packer, cargo owner, warehouse operator, etc.

There could be cases where multiple causes overlap.

For example, if the cargo has a high moisture content combined with insufficient moisture barrier packing, and further condensation occurs due to temperature differences along the route, it is necessary to individually assess the inherent nature of the cargo, pre-shipment quality, packing, and transport environment.

Clause 4.4 and the Inherent Nature of Cargo

ICC 2009 Clause 4.4 excludes losses and expenses arising from inherent defects or the nature of the insured cargo.

The inherent nature of cargo refers to characteristics such as hygroscopicity, perishability, fermentation, oxidation, discoloration, volatility, drying, and spontaneous combustion that the cargo naturally possesses.

If quality changes occur during normal transit time or under usual environmental conditions without external accidental causes, Clause 4.4 may apply.

Assessment Item	Condition Likely Considered Inherent Vice	Condition Likely Considered External Accident	Supporting Documents
External Accident	No specific accident can be identified	Perforation, water leakage, equipment failure, etc. can be confirmed	Accident reports, container/warehouse records
Damage Distribution	Uniform and gradual progression throughout the cargo	Localized concentration near water entry points or similar	Damage distribution map, photos, survey
Occurrence Speed	Can be normally predicted over time	Sudden onset after the accident	Chronological inspections, temperature/humidity logs
Pre-shipment Quality	High moisture content, signs of deterioration, approaching expiry	Normal quality objectively confirmed	Inspection certificates, quality certificates, photos
Comparison with Same Lot	Similar changes occur in other shipments	Damage limited only to cargo involved in the accident	Quality records of different lots or containers

However, the mere fact that cargo is prone to deterioration does not automatically exclude all damages from coverage.

If an external accident caused the quality change or significantly worsened it beyond normal conditions, the causal relationship should be verified.

Clause 4.2 and Normal Wear and Weight Loss

Clause 4.2 excludes normal leakage, ordinary decrease in weight or volume, and usual wear and tear.

While this is similar to Clause 4.4 on Inherent Vice, Clause 4.2 specifically addresses the normal shrinkage or abrasion that is generally unavoidable during transportation.

Cargo / Phenomenon	Examples Relevant to Clause 4.2	Examples Considered as Abnormal Damage	Points to Confirm
Liquid cargo	Minor loss due to normal evaporation or adhesion	Significant leakage caused by container damage or valve failure	Allowable loss rate, container condition, quantity records
Agricultural products	Weight loss from normal drying	Decay or disposal following abnormal heating or water intrusion	Loading and discharge weights, moisture content, weather conditions
Paper / Wood	Slight moisture content variation under normal environmental conditions	Severe deformation or mold caused by water leakage or flooding	Permissible range, incident records, moisture levels
Metal parts	Minor abrasion from normal handling	Extensive corrosion due to water exposure	Packing, salt content, damage distribution

Clause 4.3 and Inadequate Packaging or Transport Preparation

ICC 2009 Clause 4.3 excludes losses caused by insufficient or improper packaging or preparation of the insured cargo to withstand the ordinary incidents of the insured transport.

For this clause, packaging includes the stowage of cargo inside the container.

Therefore, the inspection covers not only the outer cartons but also humidity control materials, desiccants, inner packaging, pallets, container liners, cargo arrangement, securing methods, ventilation, light shading, and pre-cooling, comprehensively.

Clause 4.3 Assessment Based on Packer and Packing Timing

Packing / Preparation Status	Position under Clause 4.3	Practical Considerations	Main Reference Materials
Packed by the insured themselves	Exclusion issues arise if packing is inadequate or improper	Confirm awareness of cargo characteristics	Packing specifications, work records, photographs
Packed by employees of the insured	Exclusion issues arise if packing is inadequate or improper	Check training, work standards, and inspection system	Work procedures, inspection sheets, personnel records
Packed by an independent contractor after insurance inception	Independent contractors are not included in employees under Clause 4.3	Coverage is not automatic; check other clauses and contracts	Contract agreements, work dates and times, insurance inception time
Packed by an independent contractor before insurance inception	Exclusion issues arise as packing was done prior to insurance inception	Exemption cannot be avoided simply by third-party packing	Packing date, insurance inception date, work records
Packed by the exporter before insurance inception	Exclusion issues arise as preparation was done prior to insurance inception	Confirm timing even if the packer differs from the insured	Sales terms, packing records, policies
Improper loading inside the container	Included as packing under Clause 4.3	Check for uneven loading, ventilation obstruction, moisture retention, etc.	Vanning photos, loading diagrams, work records

The mere fact that packing was done by a third party does not automatically trigger Clause 4.3.

It is necessary to verify not only who performed the packing but also whether it was before or after insurance inception, whether the packer was an independent contractor or employee, and whether damage arose from inadequate packing.

Clause 5.1.2 and Container Unsuitability

Poor packaging and unsuitability of the container or transport equipment itself should be verified separately.

If the container has holes, the doors cannot be closed, or refrigeration capacity is insufficient, the relationship with Clause 5.1.2 may become an issue.

Category	Typical Examples	Main Clause	Points to Confirm
Poor Packaging on Cargo Side	Insufficient moisture barrier, lack of desiccants, defective inner packaging	Clause 4.3	Packer, timing, suitability for cargo characteristics
Improper Container Stowage	Obstructed ventilation, uneven load distribution, cargo contact	Clause 4.3	Main party responsible for vanning, handling method, timing
Unsuitability of the Container Itself	Holes, defective doors, floor contamination	Clause 5.1.2	Recognition at loading, party responsible for loading, insurance start timing
Reefer Equipment Failure	Cooling stoppage, sensor malfunction	Basic terms, special clauses, Clause 5.1.2, etc.	Failure timing, settings, alarms, maintenance records

Differences Among ICC(A), ICC(B), and ICC(C)

Mold, discoloration, odors, and quality deterioration are terms describing the outcome of damage and do not always constitute independent insured risks by themselves.

Comparison Item	ICC(A)	ICC(B)	ICC(C)
Basic Structure	All Risks type, excluding specified exclusions	Damage caused by risks listed in Clause 1	Damage caused by a more limited list of risks than ICC(B)
Entry Point for Quality Deterioration	Consideration of whether there is accidental physical damage from an external cause	Requires causal relationship with listed risks	Requires causal relationship with a more limited list of specified risks
Mold After Rain Exposure	Considered if not excluded	If rain exposure itself is not a listed risk, applicability is questionable	Applicability is generally further limited
Discoloration After Seawater Intrusion	Check for external accident and applicable exclusions	Confirm causal link with intrusion of seawater, lake water, or river water	Confirm scope under basic terms or additional clauses
Natural Decay or Natural Discoloration	Clause 4.4 is relevant	Clause 4.4 is relevant	Clause 4.4 is relevant
Inadequate Packing	Clause 4.3 is relevant	Clause 4.3 is relevant	Clause 4.3 is relevant
Normal Wear and Tear	Clause 4.2 is relevant	Clause 4.2 is relevant	Clause 4.2 is relevant

The All Risks coverage in ICC(A) does not mean unconditional coverage for all resultant damages.

It requires confirmation that the damage is accidental physical damage and does not fall under exclusions in Clause 4, Clause 5, or other provisions.

Under ICC(B) and ICC(C), it is necessary to confirm whether the direct cause of mold or discoloration is attributable to the insured risks listed in their respective terms.

Relationship with Condensation and Moisture

Condensation inside containers and high humidity can cause mold, discoloration, corrosion, and softening of packaging materials.

However, the mere occurrence of condensation does not automatically qualify as an accidental external cause.

Possible Cause	Typical Situation	Matters to Confirm	Required Documentation
Moisture originating from cargo	Moisture was released from wood, agricultural products, or damp pallets	Moisture content at shipment, dryness condition	Moisture content inspection, drying certification
Condensation due to temperature difference	Moved from a hot and humid region to a cold region	Shipping route, external temperature, cargo temperature	Meteorological records, temperature history
Insufficient moisture protection	Insufficient use of desiccants, moisture barriers, or liners	Packing design and required quantities	Packing specifications, desiccant calculation
Container damage	Water intrusion due to punctures or door defects	External accident and container suitability	EIR, photos, damage report
Extended retention	Transport or storage period exceeded initial assumptions	Delays, cargo characteristics, insurance period	Transport timeline, storage records

The causes of condensation and moisture, and the extent of resulting quality changes, should be investigated separately.

Relation to Oil Contamination and Odor Transfer

When oil, fuel odor, chemical smells, mold odors, or other unpleasant odors transfer to cargo or packaging, even minor visible damage may render the goods unusable or unsellable.

In such cases, it is necessary to objectively verify not only the presence of odor but also the odor source, transfer route, residue on the cargo, and the impact on use or sale.

Items to Check	Main Checkpoints	Documentation	Possible Responsible Parties
Container Floor	Residues of oil, chemicals, previous cargo	Floor photographs, cleaning records, inspection reports	Container provider, carrier
Adjacent Cargo	Possibility of odor or liquid transfer	Stowing records, cargo details, leakage records	Carrier, parties related to adjacent cargo
Warehouse Environment	Floors, equipment, chemicals, storage compartments	Warehouse records, surveillance video, environmental measurements	Warehouse operator, facility manager
Cargo-Specific Odor	Whether odor is inherent to the product or indicative of deterioration	Comparison with normal goods, component analysis	Manufacturer, cargo owner
Impact on Sale and Use	Non-compliance with regulations, hygiene, or buyer standards	Quality assessment, third-party inspection, buyer standards	Determined according to the cause of damage

Quality Inspection and Survey

Inspection / Verification Item	Verifiable Aspects	Practical Purpose	Points of Caution
Survey	Damage condition, extent, cause, responsible segment	To serve as fundamental data for insurance claims and subrogation	Simultaneously check cargo, packaging, and container
Moisture Content Test	Moisture level of cargo, wood, paper, packaging materials	Compare pre-shipment quality, condensation, and storage environment	Compare with normal products or reference values
Mold and Microbiological Test	Types of microorganisms, bacterial count, hygiene issues	Objectively determine usability and marketability	Record sampling method and inspection timing
Odor Inspection	Presence of oil odor, chemical odor, mold odor, etc.	Confirm quality deterioration due to odor contamination	Do not rely solely on subjective evaluation
Component Analysis	Oxidation, decomposition, contamination, non-standard components	Verify deterioration of chemicals, foodstuffs, pharmaceuticals, etc.	Comparison with normal lot is essential
Functional Testing	Usability of mechanical and electronic parts	Distinguish between external damage and functional damage	Confirm potential for readjustment or repair
Usability and Saleability Judgment	Resale, reprocessing, change of use, need for disposal	Calculate damage amount and residual value	Do not finalize based only on cargo owner’s claims

Determining Unsaleability and Damage Amount

Even if the quality has deteriorated, it does not necessarily mean that the entire quantity will be discarded or considered a total loss immediately.

Handling Method	Points to Confirm	Impact on Damage Amount	Required Documentation
Normal Sale	Whether quality standards are met	Actual loss may be limited	Quality inspection, sales records
Discounted Sale	Rate of market value decline	Consider the difference from normal value	Regular price, discounted price, sales data
Change of Use	Possibility of repurposing for other uses	Deduct residual value	Repurposing estimate, purchase offer
Reprocessing / Repacking	Potential for quality recovery and associated costs	Consider reasonable restoration expenses	Reprocessing estimate, test results
Partial Sorting	Whether undamaged and damaged parts can be separated	Limit quantity of damage	Sorting records, quantity sheets
Disposal	Whether disposal is required for legal, hygiene, or safety reasons	Confirm residual value and disposal costs	Disposal certificate, administrative or inspection agency documents

Before carrying out disposal or resale, notify the insurance company, surveyor, and responsible parties, and preserve evidence and residual value.

Common Practical Issues

Case	Main Focus	Insurance Judgment Points	Documents to Check	Initial Response

Metal parts corroded from container condensation	Rust prevention packing and external environment	Clause 4.3, Clause 4.4, cause of accident	Rust prevention specs, salt analysis, weather records	Collect corroded parts and packing materials
Third-party packer’s moisture protection design was inadequate	Packers and packing timing	Scope of Clause 4.3 application	Outsourcing contract, packing date, insurance start date	Notify third party of liability

Comparison of Freight Forwarder Involvement Scope

The Standard Five Classifications used in this article are not classifications established by law or the entire industry, but a framework for analyzing the scope of freight forwarder involvement in this series.

Standard Five Classifications	Expected Involvement	Points to Check in Quality Deterioration Incidents	Areas Not Automatically Covered	Practical Response
Simple Intermediary	Intermediating cargo information, packaging instructions, insurance notifications, etc.	Whether special quality preservation conditions were accurately communicated	Final decision on quality guarantee or insurance indemnity payment	Promptly forward information and accident notifications to related parties
Cargo Transportation Service Provider	Transport services using carriers and warehouse operators	Arrangements of temperature, humidity, transport methods, and storage conditions	Unconditional guarantee of the cargo’s intrinsic quality	Record transport segments and management conditions
NVOCC / House B/L Issuer	Involvement in ocean transport as House B/L issuer	Consistency between received cargo information and transport conditions	Automatic responsibility for manufacturing or pre-shipment quality defects	Keep instructions and notifications given to the Master Carrier
Door-to-Door Single Contractor	Integrated arrangement of collection, packaging, warehousing, ocean transport, and delivery	Temperature and humidity, packaging, storage, and delivery condition at each stage	Unlimited liability for all accidents caused by external service providers	Manage responsibility holders and records for each process centrally
Agent/Coordinator for Specific Operations	Individual coordination of packaging, inspection, survey, temperature control, etc.	Scope of mandate, specifications, approvers, inspection criteria	Quality judgments and legal decisions beyond the mandate	Retain written instructions and approval records

The terms Contracting Carrier and Actual Carrier denote legal or contractual statuses and do not replace the Standard Five Classifications.

Example 1: Mold Damage Caused by Container Breach

Consider a case where clothing transported in a sealed container was found upon arrival with water damage to the outer boxes and widespread mold, and a breach caused by impact was confirmed on the container side wall.

Pre-shipment inspection showed no abnormalities in the clothing or packaging materials, and if cargo near the breach shows higher moisture content and mold incidence, a causal link between external water intrusion and quality deterioration can be examined.

In such cases, the ICC terms, the type of water, timing of the breach occurrence, packaging, moisture prevention measures, and extent of damage should be reviewed.

To prepare for claims against the carrier or container provider, preserve the breach site, the Equipment Interchange Receipt (EIR), the container interior, the wet packaging, and the damaged cargo.

Example 2: Natural Mold on High Moisture Content Wood

Consider a case where wooden furniture components are transported in a standard sealed container, and despite no holes or water ingress in the container, uniform mold developed throughout the cargo upon arrival.

If the wood’s moisture content before shipment was high, there is no record of drying treatment, and similar mold was found on other cargo from the same lot, the issue may relate to the cargo’s inherent characteristics or pre-shipment quality defects under Clause 4.4.

Additionally, if insufficient desiccants or moisture-proof packaging were used relative to the cargo’s moisture level, Clause 4.3 should also be considered.

It is necessary to assess the cause as a combination of cargo characteristics, pre-shipment quality, and packaging design rather than attributing it to a single factor.

Example 3: Insufficient Moisture Protection by Independent Packer

Consider a case where the cargo owner outsourced moisture-proof packing of precision machinery to an independent packing company, resulting in internal condensation and corrosion during transport.

Under Clause 4.3, independent contractors are not considered employees of the insured; however, if the packing was done before the insurance commencement, exclusions based on timing could become an issue.

Even if the packing was performed by an independent contractor after the insurance commenced, immediate insurance payment is not guaranteed. The basic conditions, causation, other exclusions, and recourse against the packing company should be reviewed.

Retain the outsourcing contract, packing date, insurance start date, moisture protection design, amount of desiccant used, work photos, and accident notification sent to the packing company.

• Authority to decide on reprocessing, discounted sales, change of use, or disposal
• Obligation to preserve damaged goods, packaging materials, and containers
• Obligation to cooperate with claims against carriers, warehouse operators, packers, etc.
• Relationship between marine cargo insurance and compensation claims
• Liability for legal fees, survey fees, disposal costs, and related expenses

Order of Priority for Judging Conflicting Documents

Items to Confirm	Documents to Prioritize	Supplementary Documents	Points to Note for Judgment
Pre-shipment Quality	Third-party inspection, manufacturing and quality records, pre-shipment photos	Staff explanations, later reports	Do not rely solely on self-declaration after the incident
Packing Contents	Work photos, packing specifications, material records	Quotations, standard specifications	Verify actual work rather than planned specifications
Packer and Packing Date/Time	Work records, outsourcing contracts, timestamps	Invoices, emails	Accurately confirm timing before and after insurance coverage begins
Temperature and Humidity History	Data loggers, reefer raw data, equipment alarms	Weather data, staff reports	Give priority to raw data over modifiable transcribed documents
Source of Water or Contamination Entry	On-site photos of containers and warehouses, component analysis	Explanations from shipping line and warehouse operator	Cross-check physical evidence with damage distribution
Unsellability	Third-party inspection, laws and standards, purchaser’s pre-set criteria	Post-incident buyer refusal notices	Do not judge only by standards newly established after the incident

Priority is given to time-stamped quality records, temperature logs, work photos, EIR, and inspection records created at the time of the incident, rather than explanations created later or oral explanations based on memory.

Common Misunderstandings

Misunderstanding	Actual Consideration	Practical Measures
Discoloration will be paid by insurance.	The cause of discoloration and the basic insurance terms and exclusions must be verified.	Check pre-shipment quality, incidents, packaging, and inspection results.
ICC(A) unconditionally covers mold.	Even All Risks policies have exclusions such as Clauses 4.2, 4.3, and 4.4.	Confirm causal relationship with accidental external events.
Quality changes themselves are insured risks under ICC(B) and ICC(C).	Quality changes must result from the specified insured perils listed.	Match direct cause with the perils in Clause 1.
All mold is caused by accidents during transportation.	Pre-shipment quality, inherent cargo nature, or packaging deficiencies may be factors.	Verify pre-shipment inspection and moisture content.
If desiccants are included, packaging is not defective.	Quantity, placement, duration, cargo moisture, and shipping route must be appropriate.	Confirm desiccant calculation and packaging specifications.
If a third party performed the packing, Clause 4.3 does not apply.	Packaging by a third party before insurance commencement can still be problematic.	Check who packed the cargo and timing relative to insurance start.
Container punctures are also considered packaging defects.	Container unsuitability relates also to Clause 5.1.2.	Confirm EIR, party responsible for loading, and awareness of unsuitability.
If the cargo’s appearance is poor, it is a total loss.	Use, reprocessing, markdown sales, and residual value should be evaluated.	Obtain quality inspection and processing cost estimates.
If the cargo owner states it is unsellable, it is unsellable.	Objective quality standards, regulations, and inspection results are required.	Confirm third-party inspection and prior sales standards.
Odor cannot be photographed, so it does not constitute damage.	In food, apparel, pharmaceuticals, etc., odor alone may render the cargo unusable.	Conduct odor and composition tests.
Once insurance compensation is paid, notification to third parties is unnecessary.	Maintaining the insurer’s subrogation rights must be ensured.	Notify carrier, warehouse operator, etc., within the deadline.

Situations When Consulting a Maritime Lawyer Is Advisable

In cases of quality deterioration damage, issues related to the cause of the accident, insurance exclusions, packaging liability, carrier responsibility, warehouse operator liability, and freight forwarder liability may arise simultaneously.

It is particularly advisable to consider consulting a lawyer specializing in maritime and logistics fields at an early stage in the following situations:

• When the amount of damage is large and multiple causes and liable parties are involved
• When the applicability of Clause 4.3 or Clause 4.4 is under dispute
• When it is difficult to distinguish between pre-shipment quality and accidents occurring during transport
• When the packer, timing of packaging, or the start of insurance coverage is contested
• When the carrier, warehouse operator, or packer denies responsibility
• When the cargo owner has filed a claim for compensation against the freight forwarder
• When mass disposal, regulatory compliance, or sales suspension is required

Differences Between Cargo Insurance and Freight Forwarder Liability

Comparison Item	Cargo Insurance	Freight Forwarder Liability	Practical Points for Confirmation
Subject of Coverage	Damage to the insured cargo	Legal and contractual liability borne by the freight forwarder	Separate physical damage from liability
Criteria for Judgment	Covered risks, exclusions, insurance period, causation	Contractual obligations, negligence, causation, liability limits	Do not equate insurance denial with absence of liability
Cargo-specific Characteristics	Clause 4.4 may be relevant	Generally requires separate proof of freight forwarder’s negligence	Confirm provision and communication of cargo information
Packaging Deficiencies	Clause 4.3 may be relevant	Confirm whether packaging was accepted or there was a duty to provide instructions	Verify scope of work and responsible party for packaging
Post-incident Response	Insurance notification, survey, damage evaluation	Evidence preservation, liability notification, compensation negotiation	Proceed with both processes in parallel

Points to Note in Freight Forwarder Operations

Freight forwarders and NVOCCs should not immediately assume that mold, discoloration, or quality deterioration discovered is due to a transport accident or their own responsibility.

First, they should organize information regarding the cargo characteristics, pre-shipment quality, packaging, moisture protection, temperature and humidity, container condition, storage environment, and the sequence of events during the incident.

If the cargo owner had provided special instructions on temperature, humidity, ventilation, light shielding, moisture prevention, or quality maintenance conditions, it should be confirmed whether this information was accurately communicated to the carrier, warehouse operators, packers, and others.

Conversely, if the freight forwarder was not informed of the cargo properties and did not undertake packaging or quality control, the scope of their responsibilities should be made clear.

After an incident, claims for marine cargo insurance and claims against third parties such as carriers, warehouse operators, and packers should be handled separately.

Containers, packing materials, temperature data, surveillance footage, and other evidence may be lost quickly, so preservation should be requested immediately after the incident is discovered.

Summary

For mold, discoloration, and quality deterioration damage, confirming the cause and causal relationship is more important than the appearance of the damage.

ICC 2009 Clause 4.2 excludes ordinary leakage, normal weight loss, and ordinary wear and tear; Clause 4.3 excludes inadequate or improper packing or preparation for shipment; and Clause 4.4 excludes inherent defects or qualities of the cargo.

Container loading is included in the packing referred to in Clause 4.3. It is necessary to confirm both the packer and the timing of packing, as issues can arise not only from packing done by the insured or their employees but also from packing done before the insurance commenced.

Independent contractors are not considered employees under Clause 4.3; however, the mere fact that an independent contractor performed the packing does not automatically exclude coverage.

If the container or transport equipment itself was not suitable for safe transportation, this should be examined separately in relation to Clause 5.1.2, apart from any packing defects.

ICC(A) is an All Risks type, excluding specified exceptions, but ICC(B) and ICC(C) require a causal link between the perils listed in Clause 1 and the quality deterioration. In all conditions, the exclusions under Clauses 4.2, 4.3, and 4.4 should be checked.

The inherent nature of the cargo, pre-shipment quality defects, and packing deficiencies tend to be structurally excluded from insurance coverage because they stem from the cargo itself or the preparation stage before commencement of transit, rather than accidental external events.

On the other hand, accidental incidents such as container punctures, warehouse water leaks, unexpected temperature deviations, or external contamination causing quality deterioration should be considered for coverage based on the basic insurance terms and exclusion clauses.

Quality changes are difficult to assess from photographs alone; therefore, objective tests such as moisture content, mold/microbial presence, odors, composition, and functional evaluation are important.

When determining whether cargo is unsalable or a total loss, it is essential to check possibilities for reprocessing, sorting, discounted sale, change of use, and residual value, and not to decide on total disposal solely based on the cargo owner's claims.

The specific applicability of coverage, application of exclusion clauses, damage amount, packing responsibility, carrier liability, warehouse operator responsibility, and freight forwarder liability vary depending on the actual insurance policy, special clauses, packing timing, cargo characteristics, cause of incident, inspection results, and individual factual circumstances.
