When the Carrier's Cargo Insurer Says No: The Policy Brokers Keep Forgetting

Last spring I got a call from a broker in Dallas who had moved a reefer load for a chemical distributor. Specialty resins — 44,000 pounds, $380,000 declared value — from Houston to Memphis. Somewhere in the Tennessee heat, the reefer unit cycled down for six hours and held a temperature forty degrees above the required setpoint. The resin solidified in the trailer. Total loss.

The carrier had a $100,000 cargo policy. The insurer looked at the loss and said: mechanical breakdown, excluded. Right in the policy form. Denied in full.

The broker had verified the COI. The ACORD 25 showed the right limit, the right insurer, the right effective dates. Everything looked clean. What the broker didn't have was a contingent cargo policy — their own coverage that would have caught the claim when the carrier's insurer walked away. Three months of negotiation and a $210,000 settlement check later, they had one.

I've been thinking about that call ever since because the setup is completely ordinary. The carrier looked fine. The documentation was fine. The only gap was a single line item on the broker's own insurance program that most brokers don't think about until after a claim.

What contingent cargo insurance actually is

A contingent cargo policy is the broker's own coverage that responds when the carrier's cargo insurance doesn't. Not as a substitute for verifying the carrier's coverage — you still do that. But as a catch when that verification turns out not to protect you as well as you assumed.

The standard trigger for a contingent cargo policy is a wrongful denial: the carrier's insurer should have paid under the terms of the policy, but didn't. Some forms also respond when the carrier's limit is exhausted, when the carrier's insurer is insolvent, or when the carrier had active coverage at time of tender but the policy lapsed before the claim was submitted.

It does not, in most forms, cover situations where you tendered freight to a carrier with no cargo insurance at all. That's a different problem — you failed to verify coverage — and it exposes you to underwriting fraud questions on your own policy. Contingent cargo is for the situations where the carrier's policy was real and just didn't respond the way you expected.

Why carrier cargo claims get denied more than brokers expect

The BMC-91X on file with FMCSA tells you the carrier has an insurance policy. That's it. It doesn't tell you whether a specific loss falls within coverage.

Cargo policies have exclusions, and some of the most common ones apply to the loads that actually go wrong:

Mechanical breakdown: refrigeration unit failure, engine trouble, power loss. If the cargo spoils or heat-damages because the equipment broke, the carrier's insurer will look hard at whether this exclusion applies. Reefer loads are especially exposed.

Loading and unloading operations: if the damage happened while freight was being loaded or unloaded — and the insurer can argue it did — they'll try to exclude it. This shows up constantly in damage claims where the carrier blames how the product was packed.

Inherent vice: the product was already compromised. Insurers use this on pharmaceutical freight, perishables, and anything with a shelf life.

Contamination and vermin: not as exotic as it sounds. A trailer that wasn't cleaned before loading can cross-contaminate food-grade product. That claim gets denied fast.

Then there's the limit problem. Under 49 CFR § 387.303 Table 1, the federal minimum cargo insurance requirement for a general freight carrier is $5,000 per vehicle. Five thousand dollars — an amount set in the early 1980s and never updated. A carrier running a $5,000 cargo policy is fully compliant with every federal requirement while hauling a $500,000 load. Market practice is much better; most brokers write $100,000 minimums into their carrier agreements. But market practice and what's buried in the policy endorsements are two different things.

I've seen ACORD 25s showing $100,000 cargo limits where the underlying policy had a $25,000 per-shipment sublimit. The declarations page didn't show it. The sublimit was in an endorsement nobody requested. You don't find that until the claim.

The Carmack layer underneath all of this

The Carmack Amendment (49 U.S.C. § 14706) gives shippers a right to sue carriers directly for cargo loss. But Carmack also lets carriers limit their liability to a declared value stated in the bill of lading. If the BOL says the shipment is valued at $50,000 and the actual loss is $380,000, Carmack limits recovery to $50,000 — before the insurance question even comes up.

This matters because a broker who sees "$100K cargo coverage" on a COI and assumes the shipper is protected may be missing the fact that the BOL capped recovery at a fraction of that. The insurance is irrelevant above the declared value cap. Shippers who don't read the terms they're signing lock themselves out of full recovery and then turn around and ask why the broker didn't warn them.

I'm not a lawyer and I don't play one, but I've sat in enough post-claim conversations to know that the "who's responsible for what" question almost always turns on paperwork that existed before the load moved. The declared value line. The carrier agreement. The COI effective date versus the load date. And whether the broker has any coverage of their own when the carrier's insurer says no.

The Montgomery angle

Before Montgomery v. Caribe Transport II, freight brokers had a credible preemption argument: FAAAA preemption could block state-law negligent selection claims. The Supreme Court ended that unanimously in May 2026. Justice Barrett wrote the opinion. Brokers can now be sued in state court for negligently selecting an unsafe carrier.

The cargo claim question and the negligent selection question are different, but they compound. A shipper who loses freight and gets their cargo claim denied doesn't just ask whether the carrier was properly insured. They ask why you booked that carrier in the first place. That's the negligent selection angle, and it's now fully in play.

If you don't have contingent cargo coverage and you're facing a denied cargo claim post-Montgomery, you're funding your own defense against a claim that could include consequential damages — the downstream losses the shipper suffered because the freight didn't arrive — not just the cargo value.

What to look for if you're screening a broker

Brokers aren't required by federal regulation to carry contingent cargo. Part 371 of the FMCSA regs covers broker obligations, and the financial responsibility requirement that matters there is the $75,000 BMC-84 surety bond (or BMC-85 trust fund) — that's about the broker's financial responsibility for services rendered, not freight loss.

So if you're a shipper vetting a broker, or a 3PL evaluating which broker handles a dedicated lane, you're asking for three things:

1. BMC-84 bond status — verifiable directly on FMCSA. DOTScreener pulls this in the broker screening and shows you whether the bond is current. This one's easy to verify.

2. General liability — at least $1M per occurrence, on the ACORD 25.

3. Contingent motor truck cargo — listed on the ACORD 25, under "Description of Operations" or as a separate certificate line. Look for the limit (minimum $100K, $500K or higher if you're moving high-value freight), the insurer, and the effective dates.

Most brokers won't volunteer the contingent cargo cert. You have to ask. If they don't carry it, that goes in the file as a documented gap — not automatically disqualifying, but something the shipper needs to know before they start tendering loads.

If you're a broker who doesn't carry it

Call your E&O broker this week and ask about a contingent motor truck cargo endorsement. In most markets, the premium is modest relative to the exposure — often a few hundred to a couple thousand dollars annually depending on load volume. The cost went up after Montgomery because insurers understand what the decision means for broker liability. It's still worth having.

If you're running loads above $100,000 on a regular basis, the coverage limit matters as much as having the policy. A $100K contingent cargo limit on a broker moving pharmaceutical freight or electronics is not a real backstop. Buy to the exposure you're actually writing, not the regulatory minimum that doesn't exist.

How I document this

For every brokered load, the carrier file includes:

• ACORD 25 from the carrier showing limits, insurer, and effective dates — not just a COI number in a TMS field
• Verification that the policy was active on the day freight moved, not just at onboarding (DOTScreener's Continuous Monitoring flags when a carrier's insurance status changes after approval)
• My own contingent cargo certificate on file if I'm handling freight where the carrier's limit is close to the shipment value

When I'm evaluating a broker on behalf of a shipper client, I request the broker's ACORD 25 explicitly and check for the contingent motor truck cargo line. If it's missing, I note it in the file and flag it to the shipper before the relationship starts. They deserve to know what coverage is and isn't behind their freight.

The broker in Dallas told me she wished someone had asked her about contingent cargo before the resin load. Nobody had. Now she carries $500K. It costs her less per year than one week of the settlement she paid. That math should be obvious. For most brokers it isn't, until it is.
