Your Contingent Cargo Policy Isn't the Backstop You Think It Is

The Load That Taught Me the Hard Way

A broker I know — sharp, years of experience, not someone who cuts corners — moved a reefer load of pharmaceutical supplies from California to Illinois. Declared value: $228,000. Specialty medical equipment, temperature-sensitive. The carrier was Sunrise Express Freight LLC, MC-1247893, DOT-3567102, about seven months of authority. They had a cargo policy on file showing a $100,000 limit. He verified it on the FMCSA L&I database. Active. Green. Done.

The driver stopped in Gallup, New Mexico and turned off the reefer unit for eight hours to save on fuel. Temperature excursion. The consignee rejected the load on delivery — the temperature logs showed a 14-hour excursion above the required storage range. $228,000 in pharmaceutical supplies, unsalvageable.

The carrier's cargo insurer denied within six weeks. Reason: driver-induced reefer failure was excluded under the policy's reefer breakdown clause. The broker turned to his own contingent cargo coverage. His insurer's response: "We need the denial letter from the underlying carrier policy. We pay after the carrier's coverage formally denies." Four months of back-and-forth. Denial letter arrived. His contingent policy had a $75,000 sublimit on temperature-sensitive commodities.

He covered $153,000 out of his own pocket. Then the shipper's attorney called.

That's not a freak situation. It's a failure mode built into how contingent cargo coverage works, and most brokers don't figure it out until they're inside a claim.

What "Contingent" Actually Means

Contingent cargo coverage — also called broker's cargo, dependent cargo, or excess cargo — is specifically designed NOT to be primary insurance. Your policy doesn't compete with the carrier's policy. It waits. The trigger is one of these conditions: the carrier's cargo insurer denies the claim outright, the carrier's policy pays partially and leaves a gap, or the carrier has no cargo coverage and simply can't pay.

Until one of those conditions is formally satisfied, your policy sits on the sideline. You can't speed it up. Carrier insurers fight freight claims — it's standard practice. A $228,000 disputed claim gets full attention from their adjusters, who will look for every exclusion they can find. Reefer breakdown. Improper packing attributed to the shipper. Temperature-sensitive goods not declared as such on the BOL. Spoilage from an undisclosed commodity. These exclusions are real and they hold up.

While you're waiting for the carrier's insurer to respond, your shipper is waiting for payment. The relationship is burning. Post-Montgomery v. Caribe Transport II, LLC — the U.S. Supreme Court's unanimous May 2026 decision confirming that FAAAA doesn't preempt state-law negligent-selection claims against brokers — that waiting period now has legal consequences for you. You selected the carrier. If the loss goes uncovered and the shipper can't recover, you're a defendant.

FMCSA Doesn't Require Cargo Insurance for Most Freight

This part stops most people cold when they hear it.

49 CFR § 387.9 sets the financial responsibility minimum for motor carriers at $750,000 for general freight (vehicles over 10,001 lbs, interstate operation). That number is for PUBLIC LIABILITY — bodily injury and property damage from a highway accident. It has nothing to do with cargo.

For general commodity freight, FMCSA sets no minimum cargo insurance requirement. None. A carrier can hold valid operating authority, active FMCSA status, and zero cargo coverage, and be 100% compliant with federal regulations. The $750K floor protects other people on the road when their driver causes a crash — not your shipper's freight when it gets destroyed.

The exception is household goods movers, who must carry cargo coverage under 49 CFR § 387.303. Every other carrier: no federal floor.

This is why you can pull a carrier on SAFER, see Active status, check the L&I database, see the liability filing — and have no idea whether they have cargo coverage at all. The FMCSA doesn't require them to file it, so many don't have it. You'd have to look at the cargo line item specifically on L&I, and a blank cargo line isn't a red flag in most vetting workflows because brokers assume it's there.

A carrier with no cargo insurance who accepts your $200K electronics load is operating legally under federal regulations. If that happens, your contingent coverage becomes the only coverage — IF your policy language allows it. Some contingent policies require the underlying carrier to have cargo coverage in place as a condition of your policy activating. If the carrier has none, your policy may also deny, leaving you with nothing.

Three Ways This Fails in Practice

The trigger delay. You can't file on your contingent policy until the carrier's insurer formally responds. For disputed claims, that's weeks to months. Your shipper isn't waiting months, and your relationship with them isn't surviving it. You're paying out of pocket or spending the next six months in claim mediation while the shipper has already decided you're not a partner they trust.

The sublimit mismatch. Most contingent cargo policies have commodity-specific sublimits buried in the policy schedule. Electronics, pharmaceuticals, jewelry, alcohol, and temperature-sensitive goods often have lower per-occurrence limits than the policy maximum. A broker with a $1,000,000 annual contingent cargo policy might have a $75,000 sublimit on reefer commodities and a $50,000 sublimit on electronics. Brokers often don't know their own sublimit schedule by commodity. Most have never looked.

The shared exclusion problem. Carrier policies and contingent policies can exclude the same loss. Reefer breakdown. Pilferage without signs of forced entry. Consequential damages. Spoilage from improper packing. If the carrier's policy denies on an exclusion that also appears in your contingent policy language, you have two formal denials and no coverage from either direction.

The Cargo Limit Math You're Not Doing

When you pull a COI and see $100,000 in cargo coverage, one question should follow automatically: what is this load worth? If the answer is more than $100,000, you have an underinsurance problem that exists independent of anything your contingent policy will do about it.

The carrier's $100K limit is their ceiling. Yours starts after they deny. If they deny a $228,000 claim and your contingent policy has a $75K sublimit on reefer commodities, the math leaves $153,000 uncovered. That's not a worst-case edge case. That's what happened in the scenario above and variations of it happen constantly.

For high-value lanes — anything above $75,000 in declared value — the carrier's cargo limit needs to be compared against the load value explicitly, not assumed to be adequate. On lanes where I regularly move loads above $200,000, I require carriers to show cargo limits at or above the declared value. That requirement goes in the carrier setup record and gets re-confirmed on the COI at tender.

If a carrier can't show the coverage, they don't work that lane. Not that specific load. That lane. Because a carrier who carries $100K in cargo insurance isn't set up for high-value freight, and a single exception today becomes the expectation tomorrow.

The Timing Problem

There's one more failure mode that catches brokers who think they've got this figured out.

Even a verified, active cargo policy today might not be active at load pickup.

Under FMCSA operating rules, insurers must give advance notice before cancelling a policy — typically 30 days. The insurer files a notice of cancellation, the effective date is 30 days out, and during that window the policy technically remains active. If you're running your L&I check at carrier onboarding and not at load tender, you could be looking at a filing that's three weeks old. The pending cancellation might have been filed last week and effective in nine days, and your onboarding check is showing you a clean green.

For any load above $75,000, I pull L&I cargo status at load tender. Not at onboarding. The check takes 60 seconds and it's the only way to know the policy is active on the day the freight actually moves.

What I Actually Do Before Tendering High-Value Loads

For any load above $75,000 in declared value, three things happen before the load tender goes out:

Carrier cargo limit vs. load value. Written in the notes, not just assumed. If the COI shows $100K and the load is worth $120K, that gap doesn't get ignored. Either the carrier provides an endorsement or certificate specific to the load value, or the load doesn't move with them.

My own contingent policy sublimit for that commodity. Call your insurance broker, ask for the sublimit schedule by commodity class. It's usually a one-page attachment to your policy. Most brokers have never read it. Print it. Know what you're actually covered for before you commit to a lane that can exceed it.

For reefer loads: does their cargo policy cover driver-induced temperature excursions? Ask the carrier's dispatcher. Most small carriers have no idea what their own policy covers, and the question gets a pause or a "I'll have to check." That response is information. A carrier whose dispatcher doesn't know whether driver-induced reefer failure is covered has probably never had to deal with a cargo claim. They don't understand their own exposure, which means they also don't understand the operational behavior that could trigger it.

How I Document This

For every load above $75,000 in declared value, the vetting file includes:

• FMCSA L&I cargo insurance pull, timestamped at load tender (not just onboarding)
• Carrier's specific cargo coverage limit written into the file notes, not just attached
• My own contingent sublimit for that commodity, noted by load
• If cargo value exceeds carrier policy limit: how the gap was addressed — endorsement, load value reduced, or written acknowledgment from the shipper of the coverage gap
• For reefer loads: whether reefer breakdown or driver-induced temperature excursion coverage was confirmed, and what the dispatcher's response was

If a claim ever happens on that load, I want a file that shows I did the coverage math before the freight moved. Not a generic "insurance verified" checkbox from onboarding six weeks ago. A timestamped, load-specific record showing I compared the numbers.

The Bottom Line

Contingent cargo isn't a safety net. It's coverage-of-last-resort with its own trigger requirements, sublimits, and exclusions that can mirror the same exclusions that sink the carrier's policy. The gap between what brokers think their contingent policy covers and what it actually covers is where the $100K and $150K out-of-pocket checks get written.

FMCSA doesn't require carriers to insure your shipper's freight. The $750K they're required to carry protects people in highway accidents, not cargo. Your contingent policy won't fill that gap automatically, and it may not fill it at all depending on your sublimits and the carrier's coverage status.

Post-Montgomery, uncovered cargo losses have a straight path into state court with a negligent-selection claim attached. You picked the carrier. If the math doesn't work — carrier policy limit too low, your sublimit too low, both policies hitting the same exclusion — you're the last one standing with exposure.

Pull your sublimit schedule today. Compare it to your highest-value lanes. Do the math before you're inside a claim, not after.
