The Handshake Rate Lost. Your System Can Collect the Other One.

Primary Steel paid the negotiated rate. The freight moved. Then the carrier went bankrupt, and the estate sent a second bill for $187,923.36 on 1,081 shipments already paid. On June 21, 1990, the Supreme Court said the estate could collect. The lawful price was the tariff on file at the Interstate Commerce Commission, not the number both sides had billed and settled.

That failure mode is in front of ops leaders in the last week of September 2026. A company can hold a price everyone shook on, a price the truck ran for, and a price the system will invoice. The one that survives is the one the records can reconstruct. Q4 does not create the gap. It is when messy coverage makes the gap expensive.

There used to be one lawful price, and it was not the handshake

The command is older than trucking. The Interstate Commerce Act of 1887 barred railroads from charging anything but the published schedule. In Louisville & Nashville Railroad v. Maxwell (1915), the Supreme Court said the filed rate was the only lawful charge, deviation was not allowed on any pretext, and ignorance or a misquote was no excuse for paying or charging less or more than the file. Hardship was the point. A clerk who could "misquote" a favored shipper would turn the published price into a fiction.

Congress put motor carriers under that logic in 1935. For 45 years the rate that mattered was a tariff. Charging something else could be a penalty or a crime, and shippers were treated as if they knew the file. The Commission had already named the cheat. In a 1907 case the Court later quoted, it warned that billing clerks could become experts at errors for favored shippers, while everyone else paid the tariff. That is a permissions problem: someone inside the operation changes the number, calls it a mistake, and leaves nothing an audit can rebuild.

Deregulation changed the market and left the old rule standing

On July 1, 1980, President Carter signed the Motor Carrier Act, Public Law 96-296. He called it the end of 45 years of rules that kept trucks empty and sent them out of route. The Act pushed entry, phased out much of the antitrust immunity that let rate bureaus fix prices, and let carriers price inside a zone of reasonableness the ICC would not review. He said it would cut consumer costs by as much as $8 billion a year. That was a signing promise, not a measured result.

Entry is countable. An FTC evaluation in March 1982 found applications for operating authority rising from 6,746 in fiscal 1976 to 22,735 in fiscal 1980, then 29,311 in the twelve months after the Act. Approvals in whole or in part went from 69.8 percent in fiscal 1976 to 97.4 percent in fiscal 1980. Grants to brand-new entrants went from 468 in fiscal 1976 to 2,452 from July 1980 through June 1981. The Senate Commerce Committee, writing the record for the bill that killed the ICC, said 25,000 new carriers started between 1982 and 1990.

Brokers scaled too. After noting the Surface Freight Forwarder Deregulation Act of 1986, that 1995 report said the intermediary sector had flourished: by 1991 the ICC had licensed more than 7,000 brokers, up from 50 authorized before that law. The later FMCSA count is a different definition, so the figures should not be multiplied. The direction held. The 2023 pocket guide shows 19,443 registered property brokers in the 2018 snapshot and 30,716 as of December 30, 2022. Those are registrations, not a census of healthy books, and they price freight with no public tariff behind the number.

The 1980 Act did not repeal the common carrier's duty to file rates and charge only those rates. Contract carriage was the escape hatch. A contract carrier could be exempted from the tariff. A common carrier could not. Two trucks could haul the same freight and only one had a lawful price equal to the deal. Asset, broker, and hybrid were not the vocabulary yet. The split over who owned the binding number already was.

A bankrupt carrier collected the rate the shipper never agreed to

From 1981 to 1983, Quinn Freight Lines, a Maislin subsidiary, negotiated interstate rates with Primary Steel below its filed tariff and never filed the discounts. Maislin went bankrupt in 1983. The audit found $187,923.36 in undercharges on those 1,081 shipments. The estate billed the difference. Primary refused. The estate sued.

The ICC had tried to stop this. In Negotiated Rates decisions in 1986 and 1989, it said post-1980 competition made the old rule unnecessary, and it described an unreasonable practice in five steps. Negotiate a rate. Let the shipper rely on it as lawful. Fail to publish it. Bill and accept the low rate across many loads. Then demand the higher one, sometimes through a successor.

On June 21, 1990, Maislin Industries v. Primary Steel rejected that policy, 7 to 2. Justice Brennan wrote that nothing in the 1980 Act repealed the filing statutes. If the filed rate doctrine was an anachronism, Congress had to change it. The carrier's failure to file the discount did not let the shipper keep the discount. Justice Stevens, dissenting with Chief Justice Rehnquist, called the outcome a bonanza for the bankruptcy bar. The collector was often not the carrier that ran the truck. It was a trustee turning a quiet divergence between promise and file into someone else's receivable.

Congress repealed the tariff and left you holding the record

Congress moved, slowly. The Negotiated Rates Act, Public Law 103-180, signed December 3, 1993, was a path through claims already filed, not a new theory of price. The Trucking Industry Regulatory Reform Act of 1994 did the structural work. The Senate Commerce Committee later said TIRRA eliminated filed tariffs for independently set rates and precluded future undercharge claims on that traffic. For most independently priced freight, there was no longer a file that could ambush the deal.

The ICC Termination Act of 1995, Public Law 104-88, signed December 29, 1995, took effect January 1, 1996, and abolished the Commission. FMCSA, which opened January 1, 2000, registers carriers and brokers. It does not publish their prices.

So the government's copy of the rate is gone. The second bill is not. Congress never installed a rule for which private number wins when one company keeps several. That job sits in statuses, permissions, and billing. An asset fleet's binding number is the price of its own truck, plus that customer's accessorial rules. A broker's binding numbers are a pair, what the customer owes and what the carrier was confirmed at, and the business is the gap. A hybrid runs both on the same day. A shared status called "rated" lets the last write win, which is a private tariff with no commission left to blame.

August 2026 put two public prices on the same van mile

On September 15, 2026, DAT Freight & Analytics reported the national average dry van spot linehaul rate fell 20 cents in August, to $2.19 per mile, the steepest July-to-August drop in its 16-year history (down 8.4 percent). Van contract linehaul averaged $2.41, a 22-cent gap, after the two were roughly even in July. Van and reefer spot had sat above contract in June and July, then fell back below. Spot linehaul was still more than 30 percent above August 2025. The van Truckload Volume Index was 247, down 5 percent from July and roughly flat year over year, so this was not a volume boom. The figures are linehaul, so they are not a fuel comparison.

On September 3, 2026, C.H. Robinson cut its full-year 2026 dry van spot cost-per-mile forecast to about 30 percent above 2025 and still put 2027 about 10 percent above 2026. The stated reason was supply leaving, not a sudden jump in freight, which means a calm September can still sit on a tight market.

There is no single van rate this quarter. Van spot and van contract traded places in June, sat near each other in July, and opened a 22-cent contract premium in August, on flat van volume. A rule that assumes contract always clears above spot will mishandle the next inversion. A rule that freezes the June inversion will mishandle a month like August. Customers will not argue the index. They will ask which number you confirmed, which number covered the truck, and which number you invoiced.

Decide which number you can defend before Q4 writes it for you

You do not need a trustee to rerun 1990. You need three prices on one load, the agreed price, the executed price, and the invoiced price, and a path that lets the third one out. Q4 pushes more freight through backup covers. If the rule is unwritten, the last editor writes it.

Name the rates this operation actually uses. An asset carrier defends the price of its own truck and that shipper's accessorial terms, not a default copied from the last customer. A broker keeps the customer price and the carrier confirmation separate after cover. Folding them into one field is how margin vanishes, and how a customer is billed a number the carrier never saw. A hybrid marks which logic the load is under before a shared queue touches it. Your truck and a truck you bought this morning are not the same rate.

Refuse the old five-step pattern: quote one number, haul, accept another, then correct it later with no name on the change. The confirmed number stands unless a permissioned role changes it and records why. Anyone who can edit the sell rate, the buy rate, or an accessorial after dispatch, with no audit status, is the billing clerk the Commission warned about in 1907. Finding a truck in a tight week is not authority to rewrite what the customer owes. Detention, layover, and driver assist fail the same way when they sit in a side document and never land on the load.

Hold the shipment between delivered and invoiced when those three prices disagree. The release belongs to someone who can see both the promise and the carrier confirmation. Show each party its own number. A portal award, a spot confirmation, and a third invoice figure are three prices on one shipment. Covering off an award is a pricing event. Record whether the sell side moved. If it moved, the customer sees that before the invoice.

The Court told Congress to repeal the filed rate. Congress did, between December 1993 and January 1, 1996. The operational fact stayed, and it is specific to each book: asset mix, accessorial deals, and who may touch a rate. Two public prices just printed for the same van mile, and your book may hold a third. Ignore that and you recreate a filed rate, one number collected because the system said so. Reconstruct the one you intend to defend before the fourth quarter chooses it.

FAQ

Did the Motor Carrier Act of 1980 end filed truck rates?

No. Signed July 1, 1980, the Act eased entry and created a zone of rate freedom. It did not repeal the duty of motor common carriers to file rates and charge only those rates. Maislin said so on June 21, 1990. Contract carriers had an exemption path. Common carriers did not.

What did the Maislin estate actually bill?

Quinn Freight Lines charged Primary Steel below the filed tariff from 1981 to 1983 and never filed the discounts. After the 1983 bankruptcy, the estate claimed $187,923.36 on 1,081 shipments already paid at the negotiated rate. The Court held the filed rate governed.

When did ordinary truck tariffs end?

The Negotiated Rates Act, Public Law 103-180, signed December 3, 1993, addressed claims already in motion. TIRRA in 1994 dropped filed tariffs for independently set rates and, in the Senate Commerce Committee's words, precluded future undercharge claims on that traffic. The ICC Termination Act of 1995, Public Law 104-88, abolished the Commission effective January 1, 1996.

Why does this matter at the end of September 2026?

DAT put August 2026 van spot linehaul at $2.19 a mile and van contract linehaul at $2.41, after spot had been the higher number in June and July. Spot was still more than 30 percent above August 2025, on roughly flat van volume. Someone has to decide which of those numbers gets confirmed, covered, and invoiced.

Is the contract rate the real rate right now?

No. August's 22-cent contract premium followed a summer of the opposite spread. C.H. Robinson's September 3, 2026 update still had 2026 dry van spot cost per mile about 30 percent above 2025, and about 10 percent higher again in 2027, on capacity leaving the market. Freezing either relationship will be wrong on the next flip.

How should asset, broker, and hybrid books differ?

An asset carrier defends the price of its own truck and that customer's accessorial rules. A broker keeps customer price and carrier confirmation apart, and does not invoice a silent gap. A hybrid marks which logic a load is under before a shared billing queue. One status called "rated" will collect the wrong number.
