This Thursday, July 24, the 10% tariff that has sat on virtually every import entering the United States since February quietly expires — and almost nobody in Washington intends to save it. For most of the country that is a political story. For you it is a freight story, because tariff whiplash moves import volumes, import volumes move truckload demand, and truckload demand is what sets the rate on the next load you haul out of a port market, a rail ramp, or a distribution center fed by either one. This is one of those weeks where a policy deadline three time zones away will show up in your revenue by Labor Day.

Here is what is actually happening, why it points to an import whipsaw — a surge, then an air pocket — and the four moves a small carrier should make this week to be positioned on the right side of both.

What Actually Expires on Thursday

A quick recap, because the tariff saga has taken three sharp turns this year. In February, the Supreme Court struck down the administration’s original global tariffs, which had been imposed under the International Emergency Economic Powers Act. The White House answered with Section 122 of the Trade Act — a provision that allows a temporary import surcharge of up to 15% for a maximum of 150 days without congressional approval. That 10% global surcharge is the one that dies on July 24, and according to Transport Topics, Congress — staring at midterm elections and voter anger over prices — has little appetite to extend it. The fiscal backdrop tells you how much money has been sloshing through this system: Treasury tariff receipts swung from $31.4 billion collected in October 2025 to a $25.6 billion deficit in June 2026 as court-ordered refunds outpaced new collections. Trade lawyers note the expiration happens by operation of law — no vote, no announcement, the clock simply runs out.

The Wall Is Already Being Rebuilt

Do not mistake Thursday for the end of tariffs. The administration is racing to rebuild the wall on more durable legal ground: Section 301 investigations — the same authority behind the China tariffs that survived every court challenge since 2018. Two tracks are moving now, one proposing 10% to 12.5% tariffs on some 60 countries over forced-labor findings, and another investigating 16 trading partners, including China, the EU, and Japan, over industrial overproduction. “They’re going to raise the tariff wall again,” former administration trade official Ryan Majerus told Transport Topics. Section 301 investigations take months, which means the window between the old tariffs dying and the new ones landing — roughly August into the fall — is a duty-free gap on millions of dollars of goods. Importers can read a calendar. Orders that were postponed all spring while refunds and court rulings were unsettled now have every reason to ship immediately: the 10% is off, and the next tariff is coming. That is the definition of a pull-forward, and pull-forwards are made of truckloads.

Why This Lands on a Market That Is Already Tight

A pull-forward would matter in any market. This one lands on a market that has no slack. In the week before the July 4 holiday, spot rates moved above contract rates for the first time since February 2022 — dry van averaging $3.00 a mile, flatbed at a record $3.69 — while load postings jumped 24.7% and truck postings fell 2.6%, according to DAT and Truckstop figures reported by Truck News. DAT’s Dean Croke called the crossover a sign of “real capacity pressure.” When an import surge hits a market where capacity is already the constraint, the effect concentrates in specific places: the drayage-fed dry van lanes out of Southern California and the Inland Empire, the Savannah–Atlanta corridor, the New Jersey warehouse belt, Houston, the Chicago rail ramps, and the cross-border gateways — the same Laredo corridor we profiled in May. Then comes the other half of the whipsaw: once new Section 301 duties land, the goods that shipped early are already here, and the lanes that surged go quiet for a stretch. Carriers who treat August’s numbers as the new normal will buy trucks and take on payments at the top. Carriers who know it is a whipsaw will bank it.

Move One: Point Capacity at the Import Lanes Now

If any part of your operation can touch port-fed or ramp-fed freight, set it up this week — before the surge, not during it. That means getting carrier setups completed with two or three brokers who specialize in the port market nearest your lanes, asking your existing customers who import whether their inbound schedule changes after Thursday, and — if you run the Southeast, Texas, or Southern California — planning your empty miles to end in the markets where containers get stripped and reloaded. The carriers who capture surge pricing are the ones already approved in the right networks when the freight releases; onboarding takes days, and a surge does not wait for your paperwork.

Move Two: Do Not Sign a 12-Month Rate in a Whipsaw Month

With spot sitting above contract, every shipper and broker with a pen wants to lock you into next year’s rates at last year’s numbers before the surge makes their problem worse. Hold the line. Keep new commitments short — 90-day windows with a reopener — and reprice anything that comes up for renewal with the crossover in hand as leverage. We laid out the full playbook for this in our fall bid season piece; the tariff whipsaw only sharpens the point, because a contract signed in late July prices in none of the August demand you are about to hand the other side for free.

Move Three: Bank the Surge — Don’t Spend It

Surge revenue is the most dangerous money in trucking, because it arrives at exactly the moment your costs are also spiking. Diesel is back above $5 a gallon, and ATRI’s new benchmark puts the average cost of running a truck at a record $2.336 per mile for 2025 — before this summer’s fuel move. A $3.00 spot market on a $2.34 cost base is a real margin, but it is a temporary one. The discipline play for August: run your own cost per mile against every surge load, take the freight that clears it by a wide gap, and park the excess in the maintenance reserve and the tax account. The whipsaw’s back half — the post-tariff air pocket — is when that cash decides who is still running. The worst possible use of an August surge is a truck payment you will still owe in a November lull.

Move Four: Watch Three Signals, Not the News Cycle

You do not need to become a trade lawyer; you need three tripwires. First, set a Google Alert for “Section 301” — the day USTR announces proposed duty rates and effective dates is the day the second pull-forward begins, and the effective date itself is your warning that the air pocket is next. Second, watch load-to-truck ratios in one port market you can actually serve, weekly, so you see the surge arrive in data rather than in rumor. Third, watch the spot-versus-contract spread: as long as spot sits on top, capacity is tight and you have pricing power; when the spread flips back, the whipsaw is ending and it is time to tighten up. Ten minutes a week, three numbers, and you will be ahead of every carrier who finds out about the cycle from a slow load board in October.

One caution on the other side of the ledger: expiration does not mean every import gets cheaper. Product-specific tariffs built on other authorities — steel and aluminum, autos, the original China 301 duties — survive July 24 untouched. If you haul building products or metals, your customers’ input costs are not falling on Friday, so don’t let a broker talk your rate down on a “tariffs are over” story. They are not over; they are between rounds.

The Bottom Line

Thursday’s expiration opens a duty-free gap that importers will race through, and Washington is already building the next wall behind them. That is a whipsaw: an import surge into a market where spot already beats contract, followed by an air pocket once new Section 301 duties land. Position for the front half this week — port-market setups, short contracts, disciplined pricing — and protect yourself from the back half by banking what the surge pays instead of spending it. Tariff policy is out of your hands. Which side of the whipsaw you are standing on is not.
