Marine Cargo and Freight Insurance Claim Denied: Seaworthiness, Packing Exclusions, and All Risk vs. Named Perils

Marine cargo insurance protects goods in transit — by sea, air, road, or rail — against physical loss or damage. When goods are lost, stolen, or damaged in transit and the cargo insurer denies the claim, importers, exporters, freight forwarders, and logistics companies need to understand the specific legal and policy framework governing these disputes. Marine insurance operates under a distinct body of law with different rules than standard commercial property coverage.

How Marine Cargo Insurance Works

Marine cargo insurance is governed in the U.S. by principles drawn from maritime law and the parties' contract (the policy itself). Two primary coverage structures exist:

All Risk (Institute Cargo Clauses A, or equivalent). Covers all physical loss or damage to cargo from any external cause, except specifically excluded perils. This is the broadest and most common coverage for commercial shipments.

Named Perils (Institute Cargo Clauses B and C). Covers only the specific perils listed in the policy — fire, explosion, collision, sinking, grounding, water entry, general average. Loss from any cause not listed is not covered.

The coverage type is not always clearly communicated, and shippers sometimes believe they have "all risk" coverage when they have only named perils protection. If your claim was denied because the cause of loss is not covered, determine which coverage structure you actually purchased.

Common Marine Cargo Denial Grounds

Inherent Vice. One of the most fundamental exclusions in marine cargo insurance, inherent vice refers to the natural tendency of goods to deteriorate or cause self-damage — fresh produce that rots, goods that rust due to their own moisture content, fragile items that break from ordinary vibration. If your goods were susceptible to the type of damage that occurred due to their own inherent nature rather than an external cause, the carrier may invoke inherent vice to deny the claim.

To challenge an inherent vice denial: was the damage actually caused by an external peril (excessive moisture in the container, temperature excursion due to refrigeration failure, rough handling) rather than the goods' own nature? Expert evidence from a cargo surveyor or specialist is often necessary.

Inadequate Packing. Cargo policies typically exclude damage caused by inadequate or improper packing or preparation of the goods. If the carrier argues your goods were not appropriately packed for the rigors of transport — inadequate cushioning, improper palletizing, insufficient moisture protection — it may deny the claim.

The packing exclusion is often over-applied. Challenge it by demonstrating: (1) the packing was appropriate for the type and expected conditions of the transit; (2) the damage resulted from unusual conditions beyond what the packing was reasonably designed to withstand; (3) industry standards support the packing method used.

Unseaworthiness/Unairworthiness. Marine cargo policies may deny claims if the vessel carrying the goods was unseaworthy at the inception of the voyage and the insured had knowledge of the unseaworthiness. This exclusion is more relevant in older institute clauses; modern ICC A clauses typically extend coverage even when unseaworthiness exists, provided the insured was not complicit.

If unseaworthiness is raised, examine the specific policy wording and whether the "due diligence" or "indemnitee" exception applies.

Delay. All major marine cargo clauses exclude loss, damage, or expense caused by delay — even if the delay is caused by a covered peril. If goods spoil because a covered event delayed the voyage but the physical goods were not damaged, the loss from delay is excluded.

War and Strikes. Standard marine cargo policies exclude war risks and strikes. Separate war and strikes coverage (Institute War Clauses, Institute Strikes Clauses) must be purchased and is typically attached to the main policy. If a political event, piracy (which may qualify as war risk in some jurisdictions), or civil disturbance caused the loss, coverage depends on whether war/strikes clauses were attached.

Piracy. Piracy is specifically defined in marine insurance and may or may not be covered depending on the policy form. Under ICC A clauses, piracy is a covered all-risk peril. Some older policies or customized forms may have different treatment.

The "All Risk" Misconception

Despite the name, "all risk" cargo coverage does not cover everything. It covers all external causes of physical loss or damage except specific exclusions. Common all-risk exclusions include:

• Inherent vice and ordinary leakage/loss in weight
• Delay
• Insufficient packing
• Insolvency or financial default of the carrier
• Nuclear risk and war
• Deliberate damage or willful misconduct of the assured

"All risk" means the burden shifts: the carrier must prove a loss is excluded rather than the insured proving it's covered. This is an important procedural advantage for the insured in an all-risk claim.

Documentation and Survey Requirements

Marine cargo claims have strict documentary requirements:

• Original bill of lading and commercial invoice
• Packing list and survey report from a cargo surveyor (independent marine surveyor at destination)
• Notice of loss to the carrier within the time limits specified by the carrier's bill of lading (often 3 days for visible damage, longer for concealed damage)
• Photographs of damaged goods in original packaging

Failure to preserve the goods for inspection, dispose of damaged goods before survey, or provide timely notice to the carrier can compromise your claim. If the carrier argues you failed to comply with these obligations, assess whether strict compliance was possible and whether the carrier suffered actual prejudice.
