Cargo Insurance for Trucking

Cargo Insurance: What Every Motor Carrier Must Understand

I am Nazar Mamaev with Full Coverage Truck Insurance. Cargo insurance is the most misunderstood coverage in trucking, and it is the one that generates the most claims disputes. Most carriers know they need it. Few understand what it actually covers, what it excludes, and where the gaps are that can cost them tens of thousands of dollars.

This page explains cargo insurance from a regulatory, legal, and practical standpoint. I reference the actual federal regulations because the details matter when a $150,000 load of electronics gets damaged in transit and everyone is pointing fingers.

The Legal Foundation: Carmack Amendment

The Carmack Amendment (49 USC 14706) is the federal law that governs a motor carrier's liability for freight damage. Under Carmack, a for-hire motor carrier is strictly liable for the actual loss or injury to property it transports in interstate commerce. This means:

• You are liable for freight damage regardless of fault
• The shipper only needs to prove: (1) the freight was delivered to you in good condition, (2) it arrived damaged or did not arrive, and (3) the amount of damages
• You cannot contractually limit your Carmack liability below the actual value of the freight unless you offer the shipper a choice of rates (released value rates)

Carmack liability is absolute. If a deer runs into the side of your trailer and damages the freight, you are liable. If another driver rear-ends you at a red light and the freight shifts and breaks, you are liable. If the freight gets wet because your trailer seal failed, you are liable. The only common defenses are acts of God (tornadoes, earthquakes), acts of the shipper (improper packaging), and acts of a public enemy (terrorism).

This is why cargo insurance exists. Without it, a single freight claim can bankrupt a small carrier.

FMCSA Cargo Insurance Requirements: BMC-32 and BMC-34

Here is where the confusion starts. Under 49 CFR 387.303(b), the FMCSA only requires minimum cargo insurance for household goods (HHG) motor carriers. Specifically:

49 CFR 387.303(b)(1) - Household Goods Carriers

Household goods carriers must maintain cargo insurance with minimum limits of $5,000 per vehicle and $10,000 per occurrence. This is filed with FMCSA using one of two forms:

• BMC-34: Filed by a surety company. This is a surety bond guaranteeing cargo loss payment. Less common.
• BMC-32: Filed by an insurance company. This is an endorsement on your cargo policy certifying minimum coverage levels to the FMCSA. More common.

The BMC-32 and BMC-34 are federal filings, similar to the BMC-91 for liability. They go on record with the FMCSA and can be verified through the carrier lookup tool.

What About Non-HHG Carriers?

If you are hauling general freight, refrigerated goods, building materials, machinery, or anything other than household goods, the FMCSA does not require you to carry cargo insurance. There is no federal filing requirement for cargo coverage on non-HHG carriers.

But here is the practical reality: every freight broker, load board, and shipper requires cargo insurance as a condition of doing business. DAT, Truckstop, Amazon Relay, Uber Freight, CH Robinson, XPO, and every other load source requires proof of cargo coverage before they will tender a load. The FMCSA minimum is not the standard. The market standard is $100,000 minimum, with many requiring $250,000 or more.

So while cargo insurance is technically optional for most carriers under federal law, it is functionally mandatory if you want to haul freight.

Types of Cargo Insurance Coverage

Motor Truck Cargo (MTC) - Standard Form

This is the standard cargo policy for motor carriers. It covers physical loss or damage to freight in your care, custody, and control during transport. Standard MTC policies are "all risk" with named exclusions, meaning they cover everything unless specifically excluded.

What MTC covers:

• Collision damage (your truck is in an accident and the freight is damaged)
• Overturning
• Fire
• Theft of the entire vehicle (not always theft of contents, check your policy)
• Weather damage during transit
• Loading and unloading damage (varies by policy)

Broad Form Cargo

A broader version of MTC that includes additional perils like:

• Theft of contents from a locked, unattended vehicle (standard MTC often excludes this)
• Mechanical breakdown of refrigeration units
• Contamination
• Mysterious disappearance

Broad form costs 20-40% more than standard MTC but eliminates many of the gaps that generate denied claims.

Contingent Cargo

Contingent cargo insurance is purchased by freight brokers to cover the gap when a carrier's cargo insurance fails to respond. If a carrier's policy is cancelled, excludes the loss, or has insufficient limits, the broker's contingent cargo policy fills the gap. This is not a motor carrier product, but brokers you work with should carry it.

Coverage Limits: How Much Do You Need?

Your cargo limit should reflect the maximum value of any single load you haul. Here are standard limits by cargo type:

• General dry freight: $100,000 is standard. Many brokers require $250,000.
• Refrigerated goods: $100,000 - $250,000. Higher-value perishables may need $500,000.
• Electronics, pharmaceuticals: $250,000 - $500,000+. Some loads exceed $1,000,000.
• Building materials: $100,000 is usually sufficient.
• Machinery and equipment: $100,000 - $500,000 depending on individual load values.
• Household goods: $50,000 - $250,000 depending on shipment type (local moves vs. interstate).

Your cargo limit is a per-occurrence limit, not an annual aggregate. If you carry $100,000 in coverage, you can have multiple $100,000 claims in a single year (though your underwriter will not be happy about it).

Common Cargo Insurance Exclusions

This is where most carriers get surprised. Standard MTC policies have exclusions that create real coverage gaps:

1. Unattended Vehicle Theft

Many standard cargo policies exclude theft when the truck is left unattended and unlocked, or sometimes any unattended vehicle theft. If your truck is parked overnight at a rest stop and the cargo is stolen, your policy may not cover it. Broad form cargo eliminates or narrows this exclusion.

2. Refrigeration Breakdown (Reefer Failure)

Standard MTC does not cover spoilage caused by mechanical failure of your refrigeration unit. If your reefer unit dies and a $80,000 load of produce spoils, standard cargo does not pay. You need a refrigeration breakdown rider (also called a reefer breakdown endorsement). This adds $300-$800 per year to your cargo premium and is absolutely essential for any carrier hauling temperature-controlled freight.

3. Shipper Load and Count

If the shipper loads and seals the trailer and you deliver with seals intact, but the receiver claims a shortage, most cargo policies exclude "shipper load and count" claims. The logic is that you never had custody of the individual items inside the sealed trailer. This is a significant exclusion for carriers hauling sealed, pre-loaded trailers.

4. Inadequate Packaging

If the shipper packages the freight poorly and it is damaged in transit due to normal transportation conditions (not an accident), your cargo policy likely excludes it. The shipper's poor packaging is a defense under both Carmack and under the cargo policy exclusion.

5. Intentional Acts and Employee Dishonesty

If your driver intentionally steals or damages freight, your cargo policy excludes it. You would need a separate fidelity bond or crime policy to cover employee dishonesty.

6. Hazardous Materials

Standard cargo policies exclude hazmat shipments unless specifically endorsed. If you haul any classified hazardous material, you need a hazmat endorsement on your cargo policy. This adds to cost and not all carriers offer it.

Cargo Insurance Costs

Cargo premiums are based on your limit, deductible, cargo type, loss history, and number of trucks:

• $100K limit, $1,000 deductible, dry van: $1,000 - $1,800/year
• $100K limit, $2,500 deductible, dry van: $800 - $1,400/year
• $250K limit, $2,500 deductible, dry van: $1,400 - $2,500/year
• $100K limit, $1,000 deductible, reefer (with breakdown rider): $1,800 - $3,000/year
• $250K limit, $2,500 deductible, flatbed: $1,500 - $2,800/year
• $500K limit, $5,000 deductible, high-value freight: $3,000 - $6,000/year

These are annual premiums for the policy, not per truck. Cargo coverage is written on a per-occurrence basis for your entire operation.

Filing a Cargo Claim: How the Process Works

When freight is damaged, here is the standard process:

1. Document everything at delivery: Take photos of the damage, note it on the bill of lading (BOL), and have the receiver sign acknowledging the damage.
2. Notify your broker and your insurance carrier immediately. Most policies require notice within 30 days, but sooner is always better.
3. Preserve the damaged freight. Do not dispose of it until the insurance adjuster has inspected or authorized disposal. Disposing of evidence kills your claim.
4. Provide documentation: BOL showing good condition at pickup, delivery receipt noting damage, photos, repair estimates or replacement value documentation.
5. Claim is investigated and paid. Standard cargo claims take 30-90 days to resolve. Complex claims with coverage disputes take longer.

Cargo Insurance for Specific Operations

Refrigerated (Reefer) Carriers

Reefer operations need standard MTC plus a refrigeration breakdown rider. Additionally, document your reefer unit's temperature at pickup and delivery. Many policies require continuous temperature monitoring. If you cannot prove the reefer was maintaining proper temperature, a spoilage claim gets complicated.

Pre-cool your reefer before loading. A reefer unit is designed to maintain temperature, not bring it down. If you load warm freight into a warm trailer and it spoils, that is on you.

Flatbed Carriers

Flatbed cargo is more exposed to weather, road debris, and securement failures. Your cargo policy should cover improper load securement if it does not exclude it. Invest in quality straps, tarps, and edge protectors, and train your drivers on FMCSA securement requirements under 49 CFR 393 Subpart I.

Auto Haulers

Auto haulers need higher cargo limits because a single load of vehicles can be worth $300,000-$1,000,000+. Standard cargo limits of $100K are wildly insufficient. Auto hauler cargo policies are a specialty product with specific terms for vehicle damage during loading, unloading, and transport.

Hazmat Carriers

Hazmat cargo requires specific endorsements and often a separate cleanup and environmental liability component. A hazmat spill creates cargo damage AND environmental remediation costs that can reach millions. Standard cargo does not cover the environmental cleanup. You need pollution liability coverage in addition to cargo.

How to Get a Cargo Insurance Quote

To quote cargo coverage, I need:

• DOT and MC number
• Types of cargo you haul (be specific: "general freight" vs. "refrigerated produce" vs. "electronics" makes a big difference)
• Maximum load value you expect to haul
• Number of trucks
• 3-year claims history (loss runs from current carrier)
• Whether you need reefer breakdown, hazmat endorsement, or other specialty riders

Start your application here and I will quote cargo coverage from multiple A-rated carriers to find the best combination of coverage and price for your operation.

Frequently Asked Questions

Is cargo insurance legally required for trucking companies?

Under 49 CFR 387.303(b), the FMCSA only requires cargo insurance for household goods carriers. General freight, reefer, flatbed, and other carrier types have no federal cargo insurance requirement. However, every broker, load board, and shipper requires it contractually. You cannot haul freight commercially without it.

What is the difference between BMC-32 and BMC-34?

The BMC-32 is an insurance filing where your cargo insurance carrier certifies minimum coverage levels to the FMCSA. The BMC-34 is a surety bond filing where a surety company guarantees cargo loss payment. Both satisfy the FMCSA cargo insurance requirement for household goods carriers, but the BMC-32 (insurance filing) is far more common. Non-HHG carriers do not file either form since they have no federal cargo requirement.

Does cargo insurance cover stolen loads?

It depends on the circumstances and your policy terms. Most standard policies cover theft of the entire vehicle and cargo (truck hijacking). Many exclude theft of cargo from an unattended vehicle, especially if unlocked. Broad form cargo policies provide better theft coverage, including theft from locked, unattended vehicles. Read your policy's theft exclusions carefully.

What is a refrigeration breakdown rider?

A refrigeration breakdown rider (or reefer breakdown endorsement) adds coverage for cargo spoilage caused by mechanical failure of your reefer unit. Standard cargo policies exclude this peril. The rider costs $300-$800 per year and is essential for any carrier hauling temperature-controlled freight. Without it, a reefer unit failure that spoils a $50,000 load of meat is an uninsured loss.

How does the Carmack Amendment affect my cargo insurance?

The Carmack Amendment makes you strictly liable for freight damage in interstate commerce. Your cargo insurance is what pays for that liability. Without cargo insurance, Carmack claims come directly out of your pocket. The two work together: Carmack creates the liability, your insurance pays for it. Your policy limits should match or exceed the maximum value of freight you transport.

Can brokers require more cargo insurance than I carry?

Yes. Brokers and shippers can contractually require any cargo limit they choose. If a broker requires $250,000 and you carry $100,000, you either increase your limit or do not haul that broker's freight. Some brokers require $500,000 or $1,000,000 for high-value loads. Before accepting a load, confirm your coverage meets the broker's requirements.

What happens if my cargo claim exceeds my policy limit?

You are personally liable for the difference. If you carry $100,000 in cargo insurance and a $250,000 load is destroyed, your policy pays $100,000 (minus deductible) and you owe the remaining $150,000 out of pocket under Carmack Amendment liability. This is why matching your cargo limit to your maximum load value is critical. Underinsuring to save $500 per year on premium can cost you $100,000+ on a single claim.
