What Is Cargo Insurance? Types, Costs, and Who Actually Needs It
Quick Answer
Cargo insurance protects goods against financial loss from damage, theft, or destruction during transit. Not a single product. Four distinct types cover different parties, different modes of transport, and different legal relationships. The one that applies to you depends entirely on your role in the supply chain.
If you are searching "cargo insurance," you are probably one of two people. A trucker or freight broker trying to understand your liability for other people's freight. Or a shipper trying to protect the value of goods you are sending with shipping insurance.
These are fundamentally different products. Most articles conflate them. This one does not.
The Four Types of Cargo Insurance
1. Motor Truck Cargo Insurance
This covers a carrier's legal liability for freight in their care, custody, and control. If you drive a truck and a load gets damaged in a collision, stolen from your trailer, or destroyed in a fire, motor truck cargo insurance covers your liability to the cargo owner.
One thing to be clear on: this is not the shipper's policy. It is the carrier's policy. It covers what the carrier owes the shipper when something goes wrong, not what the shipper recovers directly.
The FMCSA does not federally mandate motor truck cargo insurance for most carriers. But in practice, it is not optional. Every serious shipper and freight broker requires proof of coverage before assigning a load, typically a minimum of $100,000 per occurrence. Go without it and you lose access to business. Full stop.
What it covers: collision, fire, theft, overturn, water damage in transit.
What it does NOT cover: Certain perils catch carriers off guard. Negligent loading and unloading is excluded. Acts of war. Cargo you were not legally authorized to haul. And if you picked up freight without a proper bill of lading, expect a coverage dispute before the claim is even reviewed.
Cost: Motor truck cargo insurance typically runs $1,000 to $3,000 per year for owner-operators, depending on commodity type, coverage limits, and claims history. High-value or high-risk freight (electronics, pharmaceuticals, jewelry) commands higher premiums.
2. Contingent Cargo Insurance
This is the policy designed for freight brokers and logistics intermediaries who arrange transportation but do not physically haul the freight themselves.
The logic goes like this. A freight broker books a load with a carrier. The carrier drops the ball and the freight is damaged. The carrier's motor truck cargo policy should respond. But what if it does not? What if the carrier's insurer denies the claim, the carrier is underinsured, or the carrier has simply disappeared?
Contingent cargo insurance is what steps in when the primary carrier policy fails to respond. Not a first-line policy. A backstop.
The FMCSA requires freight brokers to carry a $75,000 surety bond (BMC-84), but this is not cargo insurance. It covers failure to pay, not cargo loss. Contingent cargo is a separate purchase, and any broker moving serious freight volume carries both.
What it does NOT cover: Contingent cargo is not a substitute for the carrier's primary policy. It does not respond to every cargo claim. It responds specifically when the carrier's coverage fails to respond first. If the carrier pays, contingent cargo stays dormant.
Cost: Contingent cargo insurance runs approximately $1,200 to $2,500 per year for a $100,000 policy limit. Brokers moving higher volumes or higher-value freight pay proportionally more.
3. Ocean and Marine Cargo Insurance
In the US, you will hear both terms used for the same thing. "Ocean cargo insurance" is the more common term in domestic freight circles when referring specifically to sea shipments. "Marine cargo insurance" is the broader industry term that technically covers any mode of transport under a marine policy, including road and air legs that connect to an ocean shipment. The coverage is functionally the same. The terminology depends on who you are talking to.
Whatever you call it, this covers goods transported by sea and typically extends to multimodal shipments that include an ocean leg.
Two main structures exist in the US market.
Annual open policy (also called a blanket policy): An ongoing policy that automatically covers all qualifying shipments up to the stated limits. Used by importers and exporters who move freight regularly. No need to declare each shipment individually.
Per-shipment policy (also called a specific cargo policy): A single-shipment policy purchased for a specific origin, destination, and cargo. Better for one-off shipments or smaller businesses that do not ship often enough to justify an annual policy.
Ocean and marine cargo insurance covers loss at sea, piracy, rough weather, container overboard events, and General Average declarations. General Average is a maritime law principle worth knowing. If part of a cargo is jettisoned to save a vessel, all cargo owners on that ship share the financial loss proportionally, whether their goods were thrown overboard or not. This is one of those clauses most shippers never know exists until they are staring at an unexpected bill.
What it does NOT cover: Inherent vice (goods that deteriorate naturally, like fresh produce without temperature controls), improper packing by the shipper, and delay claims are typically excluded. War risk is usually a separate rider. Verify both before booking an ocean shipment.
Cost: Ocean and marine cargo premiums typically run 0.1% to 0.5% of the cargo's commercial invoice value, depending on commodity, trade lane, vessel type, and coverage scope.
4. Air Cargo Insurance
Air cargo insurance covers goods transported by aircraft. Premiums are generally higher than ocean coverage because air shipments tend to involve higher-value goods (electronics, pharmaceuticals, luxury items), and the speed of transit introduces unique risks around handling and temperature sensitivity.
The Montreal Convention limits airline liability to 26 Special Drawing Rights (SDR) per kilogram of cargo, effective December 28, 2024. SDR is the International Monetary Fund's unit of account, currently valued at approximately $1.37. In practice, that works out to roughly $35 per kilogram. For a 10-kilogram electronics shipment worth $5,000, the airline's maximum liability is approximately $356. Three hundred and fifty-six dollars. That is the gap air cargo insurance fills, and it is a significant one.
What it does NOT cover: Delay claims are generally excluded. Cargo improperly packaged for air transport is also excluded (air packaging requirements are stricter than ground). And if goods were handed to a freight consolidator rather than the airline directly, the liability chain gets complicated fast.
Cost: Air cargo premiums typically run 0.25% to 0.75% of declared value, reflecting the higher commodity values and faster turnaround requirements.
Carrier Liability vs Cargo Insurance: The Distinction That Costs People Money
Every mode of transport comes with default carrier liability. It is not insurance. It is a contractual cap.
| Mode | Governing law | Default carrier liability |
|---|---|---|
| Road (US domestic) | Carmack Amendment | Actual loss, subject to contract limitations and carrier defenses |
| Ocean (US imports/exports) | COGSA (Carriage of Goods by Sea Act) | $500 per package or per customary freight unit |
| Air | Montreal Convention (updated Dec 2024) | 26 SDR per kg (~$35 per kg) |
| Rail | Carmack Amendment | Similar to road, subject to tariff limitations |
These limits are not floors. They are ceilings. A carrier can limit their liability further through tariff provisions or bill of lading terms. They can also deny claims entirely based on packaging failures, acts of God, inherent vice of the cargo, or shipper error.
Cargo insurance pays regardless of fault. Carrier liability pays only when the carrier accepts responsibility, applies its own depreciation methodology, and agrees the loss falls within its contractual obligations. Those are fundamentally different outcomes. One you control. The other you do not.
How Much Does Cargo Insurance Cost?
Several variables determine the premium.
Commodity type. Electronics, pharmaceuticals, and luxury goods attract higher rates than raw materials or bulk commodities. High-theft categories like alcohol, tobacco, and consumer electronics are rated accordingly.
Mode of transport. Ocean typically carries the lowest rates. Air is higher. Road is risk-dependent on route and commodity.
Origin and destination. Trade lanes through high-risk regions, ports with elevated pilferage rates, or countries with political instability attract premium surcharges.
Coverage type. All-risk coverage costs more than named-perils coverage. All-risk covers any external cause of loss not specifically excluded. Named-perils only covers the specific events listed in the policy. Know the difference before you sign.
Declared value. Coverage is tied to the commercial invoice value of the goods.
| Coverage type | Typical rate | Who buys it |
|---|---|---|
| Ocean / marine cargo (standard trade) | 0.1% to 0.5% of cargo value | Importers, exporters |
| Air cargo | 0.25% to 0.75% of cargo value | High-value shippers |
| Motor truck cargo | $1,000 to $3,000/year | Truckers, carriers |
| Contingent cargo | $1,200 to $2,500/year for $100k limit | Freight brokers |
| Parcel / high-value shipping insurance | 0.6% to 1% of declared value | E-commerce, individual shippers |
Who Needs Cargo Insurance
Motor carriers and owner-operators. If you haul freight for others, motor truck cargo insurance is effectively mandatory. Beyond legal requirements, a single denied cargo claim from a major shipper or broker can end commercial relationships you spent years building. Not worth the gamble.
Freight brokers. Contingent cargo insurance is the backstop for when a carrier's policy fails. Brokers who move significant volume without it are exposed to losses that have nothing to do with their own operations. The carrier messes up, and you are the one holding the bill.
Importers and exporters. If you purchase goods FOB origin (meaning the seller's responsibility ends when goods leave their facility), you own the cargo from that point forward. Ocean or marine cargo insurance is the only protection against loss at sea or in transit. No coverage equals no recourse.
E-commerce businesses and high-value shippers. Standard parcel carrier liability is capped at $100 by default for UPS and FedEx, and $100 on USPS Priority Mail and Ground Advantage, with nothing at all on First Class Package Service. For any business regularly shipping watches, electronics, jewelry, or collectibles, that gap between declared value and actual carrier liability is a real and recurring financial risk. Specialist shipping insurance from providers like Secursus fills it at 0.6% to 1% of declared value, with 72-hour claim resolution versus the 30 to 90 days you will wait going through the carriers directly.
Is Cargo Insurance Required by Law?
For most shipments, no. There is no universal legal mandate to purchase cargo insurance in the United States.
The practical picture is more nuanced.
Motor carriers: The FMCSA requires cargo insurance for household goods movers ($5,000 per vehicle, $10,000 per occurrence). For other cargo types, there is no federal mandate. But individual shippers and brokers almost universally require proof of coverage before tendering freight. Legally optional. Practically mandatory.
Ocean freight: No US law requires importers to carry ocean or marine cargo insurance. But letters of credit, trade finance arrangements, and purchase contracts frequently include insurance requirements. If your bank requires insurance as a condition of financing, it is functionally mandatory whether the law says so or not.
Air freight: No legal requirement. But airline liability under the Montreal Convention is so limited (26 SDR per kg, approximately $35) that most professional shippers treat air cargo insurance as non-negotiable for anything above commodity value.
How to Calculate Cargo Insurance
The standard calculation for a single shipment:
Total Insured Value (TIV) = Commercial Invoice Value + Freight Cost + Insurance Premium + 10% margin
The 10% margin covers incidental costs in the event of a total loss: replacement sourcing, delays, administrative expenses. Most US insurers recommend it or require it.
Example: You are shipping $50,000 of electronics. Freight costs $2,000. Estimated insurance premium at 0.3% of $52,000 is $156. Your TIV works out to $52,000 + $156 + $5,215 (10% margin) = approximately $57,371. Round up to $57,500.
For international shipments using Incoterms (the standardized trade terms that govern who owns risk at each point of the journey), the TIV calculation is the same. What changes is who is responsible for purchasing coverage. Under CIF terms, the seller buys it. Under FOB terms, the buyer buys it from the moment goods leave the origin port. If your contract does not specify, do not assume you are covered.
For ongoing annual open policies, the calculation happens per shipment at declaration, or on an estimated annual basis with adjustments at renewal.
FAQ
What is the difference between cargo insurance and freight insurance? The terms are used interchangeably across the US market. "Freight insurance" sometimes specifically refers to coverage for the freight charges themselves (the cost of shipping) rather than the goods. In most practical contexts, both terms refer to coverage for the goods in transit.
Who pays for cargo insurance, the buyer or the seller? For domestic shipments, either party can purchase coverage and it should be specified in the contract. For international shipments, it depends on the Incoterms agreed to. Under CIF (Cost, Insurance, Freight) the seller arranges and pays for insurance to the destination port. Under FOB (Free on Board) the buyer takes on responsibility and cost from the origin port. Do not assume. Specify it.
Is cargo insurance the same as shipping insurance? Not always. In US freight industry usage, "cargo insurance" most commonly refers to motor truck cargo (carrier liability coverage) or commercial ocean and transit policies for bulk freight. "Shipping insurance" more commonly refers to parcel-level coverage for individual shipments sent via UPS, FedEx, or USPS. Functionally both protect goods in transit, but the policies, underwriters, and claim processes are different.
What is motor truck cargo insurance? An inland marine policy that covers a trucking company's legal liability for goods in their care, custody, and control. If the freight they are hauling is damaged in a collision, stolen, or destroyed, this policy covers their liability to the cargo owner. The carrier's policy, not the shipper's.
What is contingent cargo insurance? A backstop policy for freight brokers and logistics intermediaries. It responds when the primary carrier's cargo insurance fails to cover a loss, whether because the claim was denied, the carrier was underinsured, or the carrier's insurer became insolvent. It does not replace the carrier's primary cargo coverage. It fills the gap when that coverage fails to respond.
How much cargo insurance do I need? For motor carriers, the industry standard is $100,000 per occurrence minimum, with many shippers requiring $250,000 or more for high-value loads. For freight brokers, contingent cargo limits should match or exceed the value of the highest-value shipment you regularly handle. For importers and exporters, coverage should equal the commercial invoice value plus freight plus a 10% margin.
Do freight forwarders provide cargo insurance? Freight forwarders can arrange cargo insurance on your behalf, but they are typically acting as an agent, not the insurer. The policy is still issued by an insurance company. Some forwarders include insurance automatically in their service. Others offer it as an add-on. Always confirm what is covered, at what declared value, and under which policy terms. Do not assume coverage exists just because you are working with a forwarder.
What does cargo insurance NOT cover? Common exclusions across all types: inherent vice (goods that deteriorate naturally), improper packing by the shipper, delay claims, war and nuclear risks (usually available as separate riders), contraband or illegal cargo, and losses caused by the insured's own negligence. Read the exclusions section of any policy before you need to file a claim. That is where the surprises are.
