  • JAH Insurance Brokers offers specialized advice to tailor coverage to each type of logistics operation.

What is international marine cargo insurance?

International marine cargo insurance is a contract that protects your goods against loss, damage, or breakage while they are being transported by sea between countries. This type of coverage takes effect from the moment the cargo leaves your warehouse of origin until it reaches the agreed-upon final destination.

Contrary to popular belief, the carrier’s liability is subject to very low legal limits. If a container falls overboard or is damaged during unloading, the compensation you would receive from the shipping line would not cover even a fraction of the actual value of your products.

That’s why this insurance isn’t an extra expense but an investment in the continuity of your business. It allows you to recover the market value of your goods and maintain cash flow in the event of unforeseen circumstances.

Why is it important to have marine cargo insurance?

Every year, thousands of containers are damaged or lost on shipping routes around the world. The causes range from storms and navigation accidents to human error in cargo handling. Without an adequate policy, all that risk falls directly on your company.

In addition, many international commercial contracts require the seller or buyer to have shipping insurance. Trade terms such as CIF (Cost, Insurance, and Freight) require the exporter to deliver the goods insured all the way to the port of destination.

Protecting goods in transit not only safeguards your investment but also strengthens your reputation with customers and business partners. You demonstrate that your operation is professional and that you are prepared for any contingency.

What risks does marine cargo insurance cover?

Coverage varies depending on the type of policy you purchase. The three main categories are the Institute Cargo Clauses, classified as A, B, and C.

Comparison of A, B, and C Clauses in Marine Cargo Insurance

Risk A B C
Theft
Seawater
Fire
Collision

Clause A: All-Risk Coverage

This is the most comprehensive option. It covers virtually any physical damage to or loss of the goods, except for the exclusions expressly mentioned in the policy. It includes theft, drops, contamination, and seawater damage, among others.

It is the recommended option for high-value cargo or fragile products that require maximum protection.

Clause B: Intermediate Coverage

It protects against specific risks such as shipwreck, fire, collision, overturning of the transport vehicle, and seawater entering the hold. It does not include theft or losses due to negligent handling.

It works well for goods with lower exposure to theft or that travel on routes with a low incidence of claims.

Clause C: Basic Coverage

It offers limited protection against major events such as fire, explosion, sinking of the vessel, and grounding. It is the most economical option, but leaves many common damage scenarios unprotected.

It is only advisable when the profit margin is very narrow and insurance costs must be minimized.

Types of Marine Cargo Insurance Policies

In addition to coverage clauses, there are different types of policies available depending on the frequency and volume of your shipments.

Single-Voyage Policy

Covers a single ocean shipment. It’s useful when you make occasional exports or imports and it doesn’t make sense to purchase annual coverage.

You must apply for the policy before each shipment, which involves more administrative work but allows you to tailor the terms to each specific transaction.

Open or Floating Policy

Covers all shipments you make during a specified period, typically one year. Each time you ship goods, you simply notify the insurer of the shipment details, and coverage is automatically activated.

This approach reduces processing time and operational costs. JAH Insurance Brokers simplifies this process with digital tools that allow insurance certificates to be issued in minutes.

Monthly Declaration Policy

Similar to the open policy, but shipment details are reported at the end of each month. It’s practical for logistics operators with a high volume of shipments who prefer to consolidate the information.

How to Determine the Insurable Value of Your Cargo?

The insurable value is the basis for calculating both the premium you’ll pay and the compensation you’d receive in the event of a claim. There are several ways to determine it, depending on market practices.

CIF Value Plus an Additional Percentage

The most common method is to insure the CIF value (cost of goods + freight + insurance) plus an additional margin of between 10% and 20%. This margin covers unforeseen expenses such as customs clearance, replacement costs, and loss of expected profits.

Commercial Invoice Value

Some exporters prefer to insure only the value invoiced to the buyer. This alternative reduces the premium but also limits compensation in the event of a total loss.

Replacement value

For goods that are difficult to replace or have long production lead times, it is advisable to insure the cost of replacing the product in the destination market. This ensures that you will be able to fulfill your obligation to your customer even if the original shipment is lost.

What are the most common exclusions?

No policy covers absolutely everything. Knowing the exclusions helps you avoid unpleasant surprises when filing a claim.

Natural wear and tear

Insurance does not cover losses caused by the normal aging of the goods, gradual oxidation, or the product’s natural decomposition. The exporter is expected to take appropriate measures to preserve the goods.

Inadequate packaging

If the cargo is damaged because the packaging was insufficient to withstand normal maritime transport conditions, the insurer may deny the claim. Deficient packaging is the shipper’s responsibility.

Delays and Loss of Market

Cargo insurance does not cover financial losses resulting from delivery delays. If your goods arrive late and you lose a sale, that loss is not covered unless you purchase a specific extension of coverage.

Wars, strikes, and terrorism

These risks are typically excluded from standard coverage. However, you can add them through additional clauses if your goods will be passing through areas of conflict or political instability.

What information do you need to get an insurance quote?

When you request a quote, the broker or insurer will ask you for specific details about your shipment. Having this information ready speeds up the process.

Details about the goods

Detailed description of the product, quantity, weight, dimensions, and commercial value. If the cargo is hazardous or perishable, you must indicate this so the policy includes the appropriate conditions.

Route and mode of transportation

Port of origin, port of destination, planned transshipments, and name of the carrier. It’s also important to specify whether the cargo will be shipped in a full container (FCL) or consolidated with other goods (LCL).

Agreed Incoterm

The trade term defines who assumes the risk at each stage of the journey. Knowing the Incoterm allows the insurer to determine the scope of coverage for the goods.

Claims history

If you’ve had previous claims, you’ll likely be asked about them. A clean claims history can help you secure better premium rates.

5 Criteria for Choosing the Right Policy

Not all policies are the same, nor do they all fit your needs. These criteria will help you make an informed decision.

1. Coverage level commensurate with the value of the goods

If you export high-value products, the difference in premium between basic coverage and all-risk coverage is usually minimal compared to the amount you could lose. Don’t skimp on protection when the potential impact is significant.

2. Financial strength of the insurer

Verify that the insurance company has the capacity to pay out large claims. Ratings from agencies such as A.M. Best, Standard & Poor’s, or Fitch provide an objective measure of the insurer’s stability.

3. Experience in international trade

An insurer with a track record in marine cargo understands the specific characteristics of shipping routes, ports, and types of goods. That experience translates into better-designed coverage and more streamlined claims processes.

4. Network of correspondents and adjusters

When a loss occurs at a distant port, you need someone to inspect the cargo quickly. A global network of adjusters speeds up damage assessment and the payment of compensation.

5. Personalized advice

Every operation has its own specific risks. JAH Insurance Brokers offers specialized guidance to identify exposures, compare alternatives, and structure the coverage that best suits your type of cargo and route.

Common Mistakes When Purchasing Marine Cargo Insurance

Many exporters and importers make mistakes that reduce their protection or unnecessarily increase the premium.

Underinsuring the cargo

Declaring a value lower than the actual value to pay a lower premium seems like a good idea until a loss occurs. The indemnity is calculated proportionally, so you would receive less than what is needed to replace the cargo.

Failing to Review Exclusions

Signing the policy without reading it is risky. Some exclusions are negotiable or can be removed by paying a small surcharge. Knowing them ahead of time allows you to make informed decisions.

Forgetting About Land Legs

Maritime transport rarely begins at the port. Your cargo first travels by truck or train to the dock. If the policy doesn’t cover that leg of the journey, any damage that occurs before shipment remains unprotected.

Relying solely on the carrier’s insurance

The shipper’s civil liability is capped at very low limits set by international conventions. In many cases, the maximum compensation does not exceed a few dollars per kilogram. Your own cargo insurance is the only way to guarantee the actual value of your goods.

What to Do in the Event of a Claim?

If your cargo is damaged or lost, acting quickly is essential to obtaining fair compensation.

Document the damage immediately

Take photos and videos of the condition of the goods upon receipt. Note the container number, the seals, and any visible anomalies on the outer packaging.

Notify the insurer and the broker

Contact JAH Insurance Brokers or your insurer within the first 24 to 48 hours. Provide all shipping documentation: bill of lading, commercial invoice, packing list, and photos of the damage.

Request an adjuster’s inspection

The insurer will appoint an independent adjuster to assess the extent of the damage. Cooperate by providing the adjuster with access to the goods and all the information they require.

Preserve the damaged goods

Do not discard or repair anything until the adjuster has completed their inspection. Tampering with evidence can complicate or invalidate your claim.

Frequently Asked Questions About International Marine Cargo Insurance

Is it mandatory to purchase marine cargo insurance?

Legally, it isn’t always required, but many commercial contracts and letters of credit mandate it. Furthermore, operating without insurance exposes your working capital to unforeseen losses that could jeopardize the viability of your business.

How much does marine cargo insurance cost?

The premium depends on the value of the goods, the type of product, the route, the claims history, and the level of coverage chosen. In general, it ranges from 0.1% to 1% of the insured value. JAH Insurance Brokers helps you find the best balance between coverage and cost.

What is the difference between cargo insurance and carrier liability?

Cargo insurance is purchased by the owner of the goods to cover the actual value of their products. Carrier liability has very low legal limits and applies only if negligence is proven. Your own insurance guarantees you adequate compensation without relying on third parties.

Can I insure goods that are already in transit?

It depends on the insurer and the circumstances. Some insurers accept retroactive coverage if the cargo has not yet reached its destination and there is no knowledge of damage. Ideally, you should purchase the insurance before shipment to avoid complications.

What should I do if my cargo is damaged at a foreign port?

Notify JAH Insurance Brokers immediately. We have a network of correspondents in major ports around the world who can inspect your cargo and facilitate the claims process no matter where the incident occurs.

Does the insurance cover goods in refrigerated containers?

Yes, but it requires special conditions. You must declare that the cargo is traveling in a reefer container and specify the required temperature range. JAH Insurance Brokers offers specific cold chain coverage to protect your perishable goods.
