Marine Cargo Insurance: Why Importers Should Purchase Their Own Coverage

If you import goods into the United States, you are exposed to cargo loss from the moment your supplier loads merchandise onto a truck or vessel until it arrives at your warehouse. Most importers rely on their exporter's insurance or assume the ocean carrier will cover losses. Both assumptions create dangerous gaps. This article covers the practical side of marine cargo insurance — who should buy it, what type to buy, how long coverage lasts after delivery, and how to handle claims when something goes wrong.

For a deeper look at the legal framework, marine surveyor dynamics, and how a public adjuster fits into the claims process, see our companion article on marine cargo insurance claims.

Why the Importer — Not the Exporter — Should Purchase the Insurance

This is the single most important piece of practical advice in marine cargo insurance: if you are importing goods, you should be the one purchasing and controlling the cargo insurance policy. Do not rely on your supplier's coverage, even if the trade terms say they will provide it. Here is why.

You Control the Claim

When you own the policy, you file the claim directly with an insurer you chose. You do not have to ask your exporter to file on your behalf, wait for them to follow up, or wonder whether they reported the loss accurately. You pick up the phone, call your insurer, and manage the process yourself. When the exporter owns the policy, you are a third party trying to recover through someone else's contract — someone who has no financial incentive to fight for your full recovery because the goods already left their hands.

You Choose the Insurer and Jurisdiction

When an exporter in China, Vietnam, or India arranges cargo insurance, they typically place it with a local insurer in their own country. If a loss occurs and you need to make a claim, you may find yourself dealing with an insurance company thousands of miles away, operating under a different legal system, in a different language, in a time zone that makes communication nearly impossible. By purchasing your own policy through a US-based or European-based carrier, you ensure that:

• The insurer is subject to your state's insurance regulations and department of insurance oversight
• Claims handling occurs in your time zone with adjusters who speak your language
• You have access to regulatory complaint processes if the insurer acts in bad faith
• Legal disputes, if they arise, can be resolved in courts accessible to you

You Set the Coverage Limits and Terms

Exporters who provide insurance as part of CIF (Cost, Insurance, and Freight) terms are only required under Incoterms rules to provide minimum coverage — typically Institute Cargo Clause C, with coverage at 110% of invoice value. This is the narrowest coverage available, protecting against only a short list of catastrophic perils. If your goods are damaged by rain, theft, rough handling, or contamination, Clause C will not pay. When you buy your own policy, you choose the coverage level, the deductible, and the insured value — and you are not stuck with whatever minimum your supplier thought was acceptable.

You Avoid the “Black Hole” Problem

One of the most common complaints from importers who relied on their exporter's insurance: the claim disappears into a black hole. The exporter files the claim with their local insurer, then stops responding to your emails about the status. The foreign insurer has no obligation to communicate with you because you are not their policyholder. Weeks turn into months. The claim may have been denied without your knowledge. You have no access to the denial letter, no ability to dispute it, and no regulatory body to complain to. This scenario is entirely avoidable if you own the policy.

Why US or European Carriers Work Better for Importers

When selecting a marine cargo insurer, US-based importers should strongly prefer carriers domiciled in the United States or in well-regulated European markets (UK, Germany, France, Scandinavia). This is not about specific company names — it is about structural advantages that matter enormously at claim time.

Regulatory Protections

Insurers licensed in US states are subject to state insurance department oversight, including fair claims settlement practices regulations. In California, for example, an insurer that unreasonably delays or denies a cargo claim faces potential penalties under the Unfair Practices Act and the Fair Claims Settlement Practices Regulations. These regulatory teeth do not exist when your policy is written by an insurer in a country with weak or nonexistent consumer protection laws.

Claims Handling Accessibility

A US or European carrier will have claims offices, surveyors, and adjusters available in the same hemisphere and often the same country as the destination. When damage is discovered at your warehouse in Los Angeles, you need an inspection within days — not a two-week wait for an insurer in a distant time zone to assign a surveyor. Domestically regulated carriers maintain networks of approved surveyors and can mobilize quickly.

Communication and Documentation

Claims correspondence, policy interpretation disputes, and settlement negotiations are immeasurably easier when conducted in English with professionals who understand US commercial expectations. When your insurer operates in a different language and legal tradition, even basic communications become burdensome, and nuanced coverage arguments become nearly impossible to make effectively.

CIF vs. FOB: How Trade Terms Affect Who Bears the Risk

International trade terms — known as Incoterms — define when risk of loss transfers from seller to buyer during transit. Understanding these terms is essential because they determine who has an insurable interest at each point in the journey.

FOB (Free on Board)

Under FOB terms, risk passes to the buyer once the goods are loaded on the vessel at the port of origin. From that point forward, the buyer bears all risk of loss or damage during ocean transit and inland delivery. This is the most common arrangement for US importers from Asia. Because risk transfers at the origin port, the importer has clear insurable interest for the entire ocean and inland leg — making it straightforward to purchase their own cargo insurance.

CIF (Cost, Insurance, and Freight)

Under CIF terms, the seller arranges and pays for insurance during ocean transit. However — and this is the critical point many importers miss — risk still passes to the buyer at the port of origin, the same as FOB. The seller provides insurance as a contractual obligation, but the buyer bears the risk. This means that even under CIF terms, the buyer is the one who suffers the loss if cargo is damaged. The seller's insurance obligation is a convenience, not a substitute for the buyer having control over their own coverage.

The Practical Implication

Regardless of whether you buy FOB or CIF, you — the importer — bear the risk of loss during ocean transit. The difference is only whether the seller arranges minimal insurance on your behalf. In either case, purchasing your own comprehensive cargo policy gives you better coverage, direct claim access, and peace of mind. Many experienced importers negotiate FOB pricing specifically so they can control their own insurance without paying the seller a markup for inferior coverage.

Institute Cargo Clauses: Understanding A, B, and C Coverage

Marine cargo insurance policies worldwide are typically written using the Institute Cargo Clauses, published by the Institute of London Underwriters (now part of the International Underwriting Association). These clauses come in three tiers — A, B, and C — representing decreasing breadth of coverage.

Institute Cargo Clause A — All Risks

Clause A is “all risks” coverage, meaning it covers loss or damage from any external cause unless specifically excluded. Standard exclusions include willful misconduct of the assured, ordinary leakage or loss in weight, inherent vice, insufficiency of packing, delay, insolvency of the carrier, and war or strikes (which can be added back by endorsement). For most importers, Clause A is the appropriate choice because it provides the broadest protection without requiring the insured to prove the loss falls within a named peril.

Institute Cargo Clause B — Named Perils (Broad)

Clause B covers a specified list of perils including fire, explosion, vessel sinking or capsizing, collision, discharge at a port of distress, earthquake, lightning, washing overboard, entry of sea water into the vessel or container, and total loss of any package lost overboard or dropped during loading or unloading. Clause B does not cover theft, pilferage, or non-delivery — significant gaps for many shippers.

Institute Cargo Clause C — Named Perils (Narrow)

Clause C is the most restrictive tier, covering only catastrophic events: fire, explosion, vessel sinking, capsizing, or stranding, collision, discharge at a port of distress, and General Average sacrifice. It does not cover theft, water damage, earthquake, lightning, or washing overboard. This is the minimum level that CIF sellers are obligated to provide. It is rarely adequate for goods with any meaningful value or susceptibility to damage.

Warehouse-to-Warehouse Coverage and the Post-Arrival Period

Marine cargo insurance policies typically provide “warehouse-to-warehouse” coverage, meaning the goods are insured from the moment they leave the seller's warehouse at origin until they arrive at the buyer's warehouse at destination. This includes all intermediate handling, transshipment, and inland transit. But what many importers do not realize is that this coverage does not terminate the instant goods arrive at your warehouse.

The 30-Day (or 60-Day) Post-Arrival Window

Under standard Institute Cargo Clause wording, coverage continues for a specified period after the goods arrive at the final warehouse. The standard duration is 60 days from discharge of the goods from the ocean vessel at the final port of discharge. Some policies provide 30 days from arrival at the insured's warehouse. The exact wording varies by policy, so checking your specific terms is essential.

This post-arrival window exists because damage sustained during transit may not be immediately apparent. Containers may sit at port for days before being trucked to your warehouse. Once at the warehouse, it may take additional time to devan (unload) the container and inspect all goods. Water damage, mold growth from moisture exposure, or concealed mechanical damage may only become visible during unpacking or quality inspection.

Why This Matters for Claims

If you discover damage during unpacking — say, two weeks after the container arrived — you are still within the coverage period. Many importers mistakenly believe they missed their window and never file a claim. Others file late because they did not know the clock was ticking. The key rules:

• Document everything immediately upon discovery, regardless of how long the goods have been in your warehouse
• Notify your insurer as soon as damage is found — do not wait to quantify the full extent
• Preserve all packaging, containers, and shipping materials as evidence of how damage occurred in transit
• Check your specific policy for the exact post-arrival duration and whether it runs from vessel discharge or warehouse arrival

General Average: The Hidden Exposure

General Average is one of the oldest principles in maritime law and one of the least understood exposures in international trade. When a vessel encounters a peril that threatens the entire voyage — a fire, structural failure, or grounding — and the ship's master takes deliberate action to save the vessel and remaining cargo (such as jettisoning containers overboard, flooding a cargo hold, or incurring extraordinary expenses for salvage), the resulting loss is shared proportionally among all cargo interests on the vessel.

This means that even if your cargo was completely unaffected by the emergency, you can be assessed a General Average contribution — a percentage of your cargo's value — to compensate cargo owners whose goods were sacrificed or to reimburse the vessel owner for extraordinary expenses. The assessment can be 10%, 20%, or even higher depending on the severity of the incident.

What Happens Without Insurance

If you do not have marine cargo insurance, the shipping line will not release your containers until you post a cash deposit or bank guarantee equal to your estimated General Average contribution. This can take months to resolve while your goods sit at port accruing demurrage and storage charges. With a cargo insurance policy in place, your insurer posts the General Average bond on your behalf, your goods are released promptly, and the insurer handles the adjustment process — which can take years to finalize — without tying up your capital.

General Average Is More Common Than You Think

Major container vessel fires, groundings, and structural failures occur multiple times per year. High-profile incidents like the Maersk Honam fire (2018), the ONE Apus container collapse (2020), and the Ever Given Suez Canal grounding (2021) each triggered General Average declarations affecting thousands of cargo interests. Without insurance, each affected importer faced potential financial paralysis waiting for their goods.

Public Adjusters Can Adjust Marine Cargo Claims

Many importers and freight professionals are surprised to learn that a licensed public adjuster can represent cargo owners on marine insurance claims. The traditional model has always involved marine surveyors working for the insurer, with the cargo owner navigating the process alone. But there is nothing in insurance law that limits public adjusters to homeowner or commercial property claims. Cargo is personal property, and a public adjuster is licensed to represent insureds on any personal property insurance claim.

What a Public Adjuster Brings to a Cargo Claim

A public adjuster with experience in trade and logistics offers cargo owners something no marine surveyor provides — advocacy. The surveyor works for the insurer. The public adjuster works for you. Specifically, a PA on a cargo claim will:

• Review the cargo policy to identify all applicable coverages, extensions, and favorable provisions the insurer may not volunteer
• Document the loss comprehensively, including consequential damages like spoilage, re-order costs, lost sales, and expediting expenses that cargo owners often forget to claim
• Challenge the marine surveyor's findings when they undervalue the loss or misattribute the cause of damage
• Ensure compliance with policy conditions (timely notice, mitigation, preservation of evidence) so the insurer cannot deny coverage on technicalities
• Negotiate the settlement directly with the insurer's marine claims adjuster, pushing for full indemnification rather than a discounted offer

PA vs. Marine Surveyor: Understanding the Difference

A marine surveyor inspects and reports. They measure the physical damage, identify probable cause, and estimate loss. They do not interpret policy language, negotiate coverage, or advocate for the insured. A public adjuster does all of those things. The surveyor's report becomes one piece of evidence in the claim file — the PA uses that report (and challenges it when needed) as part of a comprehensive claim strategy aimed at maximizing recovery.

For context on the broader role of public adjusters across all property claim types, see our overview on inland marine insurance claims, which also discusses how PAs handle non-standard property exposures.

Practical Tips for Purchasing Marine Cargo Insurance

Whether you are a first-time importer or an experienced trader looking to improve your coverage, these practical guidelines will help you make better purchasing decisions.

Open Cargo Policy vs. Single Shipment Certificates

If you import regularly, an open cargo policy (also called a blanket policy or floating policy) covers all shipments automatically as they occur. You report shipments periodically and pay premiums based on declared values. This eliminates the risk of forgetting to insure a shipment and typically provides lower rates than individual certificates. Single shipment coverage makes sense only for one-time or very infrequent imports.

Insured Value: Always Add a Margin

Standard practice is to insure cargo at 110% of CIF value (cost of goods + insurance + freight). The extra 10% accounts for anticipated profit and incidental expenses you would incur if the goods were lost and you had to re-order. Some policies allow up to 120% or higher if you can demonstrate additional costs like lost sales, expediting charges, or duty on goods that cleared customs before damage was discovered. Insuring at invoice value alone leaves you under-indemnified.

War and Strikes Clauses

Standard Institute Cargo Clauses exclude war, civil war, revolution, and strikes. These are available as separate endorsements (Institute War Clauses and Institute Strikes Clauses) and should be added to every policy. The premiums are typically modest except for cargo transiting active conflict zones, where they spike dramatically.

Duty and Increased Value Coverage

Customs duties paid on imported goods can represent a substantial additional cost. If cargo is damaged after clearing customs, you have already paid duty on goods you cannot sell. Some marine cargo policies cover duty as part of the insured value; others require a separate “increased value” endorsement. Verify how your policy handles this, especially with current tariff rates driving duties higher.

Steps to Take When You Discover Cargo Damage

The actions you take in the first 24 to 48 hours after discovering cargo damage determine the strength of your claim. Marine cargo insurers are sophisticated and will scrutinize whether you met all policy conditions. Follow these steps:

1. Photograph everything before disturbing it. Document the container seal number, external container condition, stacking damage, water intrusion marks, and the state of goods as found upon opening.
2. Note the container condition on the delivery receipt. When the trucker delivers the container, inspect it externally and note any damage, broken seals, or signs of water intrusion on the delivery receipt before signing.
3. Notify your insurer immediately. Do not wait to quantify the full loss. A brief initial notice preserving your rights is far better than a detailed notice filed late.
4. Preserve all packaging and evidence. Do not dispose of damaged goods, packaging materials, dunnage, or the container itself until the surveyor has inspected and the insurer has authorized disposal.
5. Segregate damaged from undamaged goods. Keep damaged goods separate and clearly marked. Do not commingle with other inventory.
6. Mitigate further damage. If goods are wet, move them to a dry area. If refrigerated goods lost temperature, take steps to prevent further spoilage. You have a duty to mitigate, and failure to do so can reduce your recovery.
7. Gather shipping documents. Assemble the bill of lading, commercial invoice, packing list, certificate of insurance, survey report (if already issued), and any correspondence with the carrier about the damage.
8. File a claim with the ocean carrier as well. Even if your cargo insurance will pay the claim, file a notice of claim with the ocean carrier within their required timeframe (typically 3 days for apparent damage, 3 days after delivery for concealed damage). This preserves subrogation rights for your insurer to recover from the carrier later.

Common Mistakes Importers Make With Cargo Insurance

Based on years of handling these claims, the following mistakes cost importers money over and over:

• Relying on the exporter's insurance— As discussed above, this leaves you without direct access to the claim process and often with inadequate coverage.
• Assuming the carrier is liable for full value— Ocean carrier liability under COGSA is limited to $500 per package unless higher value is declared on the bill of lading. A 40-foot container of electronics worth $200,000 may yield only $500 per carton from the carrier.
• Not inspecting promptly— The longer you wait to open the container and inspect goods, the weaker your claim becomes. Insurers will argue that damage occurred during your storage, not during transit.
• Disposing of damaged goods before inspection— Never throw away damaged goods, packaging, or dunnage before the surveyor has examined them. This eliminates physical evidence of transit damage.
• Under-insuring to save premium— Insuring at FOB value instead of CIF + 10% leaves you with a recovery that does not cover freight, insurance cost, duty, or lost profit on the damaged goods.
• Not reading the policy exclusions— Inherent vice (goods that damage themselves due to their own nature), insufficient packing, and delay are standard exclusions. If you ship perishables, ensure your policy includes temperature variation coverage. If your goods are fragile, ensure packing specifications meet the policy's requirements.
• Missing the carrier notice deadline— Filing a claim with your insurer but forgetting to file notice with the ocean carrier within 3 days can undermine your insurer's subrogation rights and create policy compliance issues.

Summary: Taking Control of Your Cargo Insurance

Marine cargo insurance is not an area where cost-cutting serves you well. The difference between a claim that pays in full and a claim that pays 40 cents on the dollar — or gets denied entirely — often comes down to decisions made long before the loss occurs. Buy your own policy. Choose a US or European carrier. Insist on Institute Cargo Clause A. Understand your post-arrival coverage window. And when a significant loss occurs, recognize that you do not have to navigate the process alone.

A public adjuster with trade and logistics expertise represents you in exactly the same way an attorney represents you in court — except in the insurance claim arena rather than the legal arena. The insurer has trained professionals working their side. You should have trained professionals working yours.
