BMC-84 vs BMC-85: The $75K Bond Difference That Only Matters When the Broker Disappears

I've talked to brokers who couldn't tell me whether they carry a BMC-84 or a BMC-85. They just know they have "the $75K bond." That's like a carrier telling you they have "cargo insurance" without knowing whether there's a $10,000 per-occurrence sublimit on refrigerated freight.

The bond type matters. It matters most in exactly the scenario where you want answers fastest: when the broker defaults, goes dark, or files for bankruptcy while your carrier hasn't been paid and your shipper is demanding documentation.

Here's what the difference actually is, and why you should be checking it on every broker you sub to — or every broker your shipper uses to hand you freight.

What FMCSA Actually Requires

Under 49 CFR Part 387, Subpart B — specifically § 387.307 — every licensed freight broker must maintain proof of financial responsibility of at least $75,000. That threshold was raised from $10,000 by MAP-21 in 2012, and yes, plenty of brokers were squeaking by on ten grand before that. The regulation doesn't care which instrument you use to satisfy it. A broker can file a BMC-84 surety bond or a BMC-85 trust fund and get the same green checkmark in FMCSA's system.

Those two instruments are not the same thing.

The BMC-84: You're Borrowing Someone Else's Balance Sheet

A BMC-84 is a surety bond. The broker goes to a bonding company — usually a large insurance carrier — and that company puts its name on a promise: if the broker defaults on a legitimate claim, the surety will pay, up to the $75K limit.

The broker pays a premium (typically a few percent of the bond amount annually), and the surety assumes the credit risk. When a claim gets filed, you're dealing with a professional financial institution that has its own legal team, its own claims process, and its own money. If the broker goes under on Monday, the surety company still exists on Tuesday.

That's the key structural advantage: the BMC-84's backing is independent of the broker's solvency. The bond issuer isn't in the same bankruptcy filing as the broker.

The BMC-85: The Broker's Own Money in a Box

A BMC-85 is a trust fund arrangement. The broker deposits $75,000 (or more) into a trust account — a separate legal vehicle — and an approved trustee holds it. The money is supposed to be available to pay valid claims from carriers and shippers the broker has harmed.

On paper, that sounds solid. The trust is a separate legal entity from the broker. The theory is that the trust assets are protected from the broker's creditors in a bankruptcy.

In practice? It's messier.

First, the trust has to actually have the money in it. The FMCSA requirement is that the balance stays above $75K. But trust account monitoring is not a real-time, continuously audited process. A broker in financial distress might raid or deplete the trust before regulators catch up. The FMCSA doesn't have daily visibility into every BMC-85 trust balance.

Second, in a real insolvency, the "separate trust" argument gets contested. Bankruptcy trustees will argue about whether the trust was properly funded, whether the commingling rules were followed, whether the trust qualifies for the protections the broker claimed. You might win that argument eventually. But you'll spend legal fees getting there, and the timeline is months to years, not days.

Third, $75,000 split among all the parties the broker stiffed is often a fraction of total claims. A mid-sized broker that goes under owing money to 50 carriers and a handful of shippers is not going to make anyone whole out of a $75K trust.

What a Real Default Looks Like

Consider this scenario. A shipper uses MC-1247893 (DOT-3567102), a regional freight broker out of the Midwest, to move three loads of manufacturing components per week — consistently $40,000 to $60,000 in freight value per move. The broker is running a BMC-85 trust fund.

Over about six months, the broker is quietly struggling. They're paying carriers late. Some carriers stop taking their loads. The broker starts using carriers they normally wouldn't — newer authorities, higher OOS rates — because the established carriers have cut them off. Then one Thursday, the broker stops answering the phone. Website goes dark. The broker files Chapter 7 that Friday.

The shipper has two loads in transit. Carriers are owed approximately $43,000 combined. They file claims against the BMC-85 trust. The trustee's position: the trust account held $61,000 at the time of filing, but some of those funds are contested because of transfers made in the prior 90 days. The proceedings take 14 months.

Now imagine the broker had been carrying a BMC-84 surety bond instead. The bonding company — a large specialty insurer still very much in business — processes valid claims against the bond. Slower than anyone wants, but not a 14-month bankruptcy proceeding.

This is not a hypothetical edge case. Broker insolvencies happen. The freight market is cyclical, margins are thin, and brokers who grew fast in a strong market sometimes collapse fast when capacity tightens.

What You Can Check

The FMCSA's SAFER database shows broker authority status, but it doesn't prominently display which instrument — BMC-84 or BMC-85 — a broker filed. You can look up a broker's insurance and bond filings through the FMCSA licensing and insurance portal (the same L&I system you check for carrier insurance).

The bond form — BMC-84 or BMC-85 — is in that record. So is the name of the surety company or trustee, and the effective date of the filing.

What you want to see with a BMC-84: a bonding company that is a recognized, rated surety. Avoid brokers bonded by shell entities or small companies with no track record. The bond is only as good as the company backing it.

What you want to see with a BMC-85: look at who the trustee is and, if you can get it, request the trust balance confirmation. Big reputable shippers ask for this. Most brokers find the request intrusive. That discomfort is information.

The Montgomery Angle

Post-Montgomery v. Caribe Transport II, shippers now have direct state-law exposure for negligent selection of carriers. That ruling is primarily about carriers — it says the FAAAA doesn't preempt state negligent-selection claims against brokers who hire unsafe carriers. But the underlying logic is the same when a shipper picks a broker: you're delegating a consequential selection decision, and if that broker is financially unstable, marginally capitalized, and using riskier carriers because reputable ones won't touch them, you have a problem.

A broker's financial health is a signal about their vetting behavior. Financially stressed brokers make different carrier selection decisions. They use whoever picks up the load. They don't maintain ongoing relationships with vetted carrier networks. They're one bad week away from disappearing with a carrier's payment.

I'm not saying every BMC-85 holder is a risk. Some sophisticated brokerages use trust funds by design, and they're well-funded and well-run. But knowing the instrument type is the first step to actually evaluating the risk — not just assuming the FMCSA checkbox means everything is fine.

What I Check When Vetting a Broker

The FMCSA authority age — how long have they been licensed? Anything under 18 months gets extra scrutiny. I want to see a track record.

The bond type and the backing entity. BMC-84 from a rated surety: good. BMC-84 from something I can't verify: question mark. BMC-85: ask the trust question.

Contingent cargo coverage. If the broker is moving freight on my shipper's account, do they carry contingent cargo? This is separate from the $75K bond, and it matters if a carrier's primary cargo policy fails to respond on a claim.

Their carrier network. Are they using fresh authorities? High OOS-rate carriers? If I pull three recent carriers they've worked with and two of them have Unsafe Driving BASICs over 75th percentile, the broker's vetting standards are not what they said in their carrier packet.

Payment record. The freight community is small. Carriers talk. A broker with a pattern of short-paying or slow-paying carriers is burning bridges with the better operators, and the ones willing to work with them are often doing so because they have no better options.

How I Document This

When screening a broker — either as a shipper evaluating a brokerage relationship or as a sub-broker due-diligence step — my file should include:

• Broker MC number and authority effective date (pulled from FMCSA)
• Bond type: BMC-84 or BMC-85, plus the name of the bonding company or trustee
• Bond effective date and confirmation that it's currently in force (not expired or under suspension)
• Whether the broker carries contingent cargo insurance and the limit
• A note on which carriers they've recently used and a quick SAFER check on two or three of them
• If BMC-85: a note acknowledging the trust fund structure and any effort made to verify the trust balance

This takes 15 minutes. For a relationship where you're moving $200,000 a month in freight through a single broker, those 15 minutes are cheap insurance.

The bond type alone doesn't tell you whether a broker is trustworthy. But it tells you what your recourse looks like when everything goes wrong. That's worth knowing before you hand them the first load.
