Supply Chain Action Points
Read this first — the conclusion, and the moves to make:
- By 10 July 2026, add a rejection-rate line to your weekly carrier scorecard for every lane you tender more than ten times a month, with the current benchmark written down: 18 percent dry van, 25 percent reefer, and 30 to 40 percent flatbed. Owner is your transportation manager, and the target is that no active lane runs a month without a first-choice failure count attached to it.
- By 17 July 2026, name a first alternate and a second alternate for every lane in your routing guide and test both with a live tender inside the quarter, because 18 percent dry van means the first choice alone will not hold and the guide as written has no failure budget.
- By 31 July 2026, run the renewal arithmetic on your own book: current rate per mile, the 50-cent move used here or your own estimate, average haul, and monthly load count. The output you want is a single dollar figure per month for dry van and per month for reefer, signed off by finance, so the next renewal is a decision and not a surprise.
- By 15 August 2026, secure reefer capacity ahead of the season for any temperature-controlled volume that cannot miss a delivery. Reefer at 25 percent rejections is the tightest of the three modes, and the target is contracted coverage for at least 80 percent of your peak reefer loads with a named carrier rather than spot.
- By 15 August 2026, put cross-border volume under review: list every lane that depends on cabotage relief capacity, confirm which carriers still hold it, and set a written fallback for each. Cabotage enforcement is tightening and the relief valve is closing, so the target is an alternative on paper for 100 percent of border-adjacent lanes before the fourth-quarter bid cycle.
The U.S. truckload market is approaching a structural capacity crunch as carrier rejections hit 18% for dry van and 25% for reefer in early June, while flatbed rejections stayed at 30-40%. ACT Research has declared a driver shortage, and Class 8 tractor orders fell to around 13,200 units in May as fleets delay replacement. With the average fleet age at a decade-high 6.3 years and cabotage enforcement tightening cross-border capacity, analysts expect elevated rates to persist into 2027.
The Analysis
Eighteen percent. That is the dry van rejection rate Arrive Logistics and ACT Research put on early June, and if you move anything on a 53-foot box in the United States right now, that number is describing your week. Reefer came in at 25 percent. Flatbed held between 30 and 40 percent. A rejection rate is not an abstract index, it is the share of tendered loads a carrier looks at and refuses. When one in four reefer loads gets turned down, the market is not merely tight. It has already made its choices for the summer, and it is telling you so.
Underneath those rejection rates sits a supply problem that has been building for years. ACT Research has declared a driver shortage outright. Class 8 tractor orders fell to roughly 13,200 units in May, and fleets are not replacing because a new tractor does not clear the rate it can earn. Average fleet age is 6.3 years, a decade high. Cabotage enforcement is tightening, which pulls cross-border capacity out of the pool. Analysts expect elevated rates to run into 2027.
I have walked enough of these lanes to know what a 30 percent flatbed rejection rate feels like at four in the afternoon when your project cargo is sitting on a shipper's dock and the sun is going down. Here is what these numbers actually do to your chain, and what you should have written down before the next bid cycle opens.
Begin with what a rejection rate is and why it leads price. In a loose market, rejections sit in the low single digits; a broker tenders a load once and a truck shows up. At 18 percent dry van, a broker has to tender roughly five loads to place four. Your routing guide has a first-choice carrier on it, and that carrier is failing on close to one in five tenders. The guide is not a plan, it is a wish list, and this summer it is a wish list that gets tested four times before anyone answers. Price is what you pay when a truck finally takes the load. Rejections are how many times you fail first. The invoice shows the first number and hides the second, and the second number is what breaks a delivery promise.
The Class 8 order number is the signal people read backwards. Thirteen thousand two hundred tractors ordered in May is not shippers asking for capacity, it is carriers declining to add it. A fleet buys a tractor when the rate on the road covers the note on the truck. At today's rates, with a replacement tractor priced where it is, the note does not clear, so orders stall. Add a fleet age of 6.3 years, a decade high, and you get a second constraint almost nobody plans for. Old trucks break. A reefer unit that goes down in July does not delay a load, it cancels it, because there is no spare reefer idling in a yard waiting for your phone call.
The cabotage piece is the one that gets lost outside the border states. Tightening enforcement pulls cross-border capacity out of the shared pool. That capacity was never on your routing guide, it was the relief valve, the trucks that appeared when domestic fleets ran short near the border. When the valve closes, a carrier in Laredo or El Paso who used to take your overflow is now booking only its own book of business. The pressure does not stay at the border. It pushes inland, one state at a time, and it arrives at your dock wearing a different carrier's name.
Layer the impact and the picture sharpens. Reefer at 25 percent hits first, because temperature-controlled freight has no substitute and no patience; produce and frozen goods take the rate and pass nothing along, they just pay. Flatbed at 30 to 40 percent hits hardest in absolute terms, because a rejected flatbed load is often a project, a crane, a build schedule, and the cost of the truck is a rounding error next to the cost of a stalled site. Dry van at 18 percent is the one everyone feels, because it is the default mode for everything that did not get special handling, and 18 percent is enough to turn a three-day transit promise into a four-day reality without anyone being able to point at a single failure.
Timing matters more than the size of the move. Rejection rates move first and they move now, but your invoice moves at your next contract renewal, which for most mid-market shippers is a quarter or two out. That gap is the whole game. A shipper who waits for the rate increase to arrive in the invoice has already spent the window when a better deal was still available. The rejection rate on your screen today is pricing your renewal.
Here is the part the headlines skip. Everyone is treating this as a driver problem, and drivers are only half of it. The order number and the fleet age together say the constraint is the pipeline, not the labor pool. Even if Class 8 orders tripled tomorrow and every seat got filled, steel and rubber still take twelve to eighteen months to become a truck on a lane. That makes waiting for rates to fall a bet against a pipeline you can already measure. When analysts expect this into 2027, that is not pessimism, that is arithmetic on a fleet aging faster than it is being replaced. The second thing the headlines skip is that your routing guide has no failure budget. Nobody writes down what happens when the first and second choice both reject. You are about to find out, and it is better to write it down before you do.
Ask what would have to change for this to be wrong. Rates come down when demand falls, not when supply is fixed, and demand falls when freight volumes drop, which is exactly the scenario nobody plans for because it is unpleasant. A sharp demand drop would flip every number here within a quarter: rejections would collapse to low single digits, carriers would chase volume, and the rate rally would end without a single new truck entering the fleet. So the condition to watch is not the driver shortage, it is your own order book and the national volume trend. If volumes hold, the supply side wins and rates grind up into 2027. If volumes break, none of this matters and the same carriers who rejected you in June are calling you in September.
Run the arithmetic on a mid-market book so the size is real. Assume a shipper moving 200 dry van loads a month at an average 800-mile haul, and assume the contract rate moves from 2.60 dollars a mile to 3.10 dollars at renewal, a 50-cent move consistent with a market where 18 percent of tenders are refused. That is 400 dollars more per load, 80,000 dollars a month, and 960,000 dollars a year on this book alone. I picked the load count, the haul and the two rates; your numbers are yours to fill in. Swap in your own monthly loads and your own haul, and the same 50 cents tells you in one line whether this is a rounding error or a budget item. On a reefer book the per-load move is larger and the rejection rate is higher, so the same formula comes out worse.
The trap waiting in this market is the cheap tender. In a tight market a low bid is not a discount, it is a signal that the carrier who quoted you has not looked at the lane or does not intend to run it, and the rejection will land on the day you cannot absorb it. Save the money on the tender and you will pay it back in overtime, in expedited trucks, and in the customer who remembers the one late delivery. Write your rejection budget down now. The market will charge you either way, and the only choice you own is whether you chose the number first.
