Street-turns: the empty leg nobody prices into the import
The leg your import invoice never names
Your container left the terminal on Tuesday, reached the warehouse on Wednesday, and was stripped on Thursday morning. As far as your accounting is concerned the file is closed. As far as the ocean carrier is concerned nothing is closed at all — its box is still sitting on your yard, and detention runs until that empty is handed back and gated in at an approved depot.
Between stripping and that gate-in sits an entire drayage move: a truck sent back for an empty box, forty miles to the depot, and a lift charged on arrival. Nobody quoted it, because the quotation stopped at delivery. It costs several hundred dollars anyway, and it is the leading cause of accidental detention among importers who — counterintuitively — unload quickly. The billing mechanics, tiers and thresholds are covered in our guide to demurrage and detention.
A street-turn deletes that leg: instead of going back to the depot, the empty goes straight to a nearby exporter loading on the same carrier. Two moves become one, two lifts become none, and the box leaves loaded. It is one of the rare optimisations that benefits both shippers and the carrier at once — and it is still refused often, for specific reasons.
What a street-turn actually is
A street-turn is the reassignment of an empty container, by road and without touching a depot, from an import booking to an export booking on the same ocean carrier. British hauliers call the same move triangulation; North American operations teams call it a match-back.
Three things have to be true at the same moment: the box is carrier-owned, because only the carrier can reassign its own equipment; an export booking is open on that same carrier, for the same size and type; and the export terminal's receiving window is open when the empty becomes available.
The desk that decides is called equipment control. It weighs what repositioning the unit would cost against what it loses in visibility by letting it go. Approval takes the form of the container number being switched onto the export booking. That switch — not your unloading — closes the import detention clock, which is why the switch date deserves care in the approval thread.
Four road legs, one clock
The full cycle involves four road moves, two of them empty. A street-turn removes one and shortens the other.
| Item | Standard depot return | Street-turn |
|---|---|---|
| Drayage legs | 3 (terminal → warehouse, warehouse → depot, depot → exporter) | 2 (terminal → warehouse, warehouse → exporter) |
| Empty miles run | 2 × distance to depot | importer → exporter distance |
| Lifts charged | 2 (depot in and depot out) | 0 |
| Detention clock stops | at depot gate-in | at the switch onto the export booking |
| Chassis days (US markets) | shorter, chassis released at depot | longer, chassis stays out to the exporter |
| Prior approval needed | none | carrier equipment control |
| Condition inspection | at the depot, by the carrier | at the export gate, at your risk |
The gross saving sits in the first three rows: one drayage leg and two lifts removed, typically in the $350–700 per box range in US short-haul markets — an indicative band driven mainly by distance to the depot. The net saving is smaller, because the chassis meter and the split of the gain between the two shippers both eat into it.
The five reasons it gets refused
1. The export booking is on a different carrier. The most common case, and fatal: a box belonging to one carrier will not load on a competitor's vessel, and alliances share vessel slots, not container fleets.
2. The calendars do not overlap. The empty is free on day D, but the export terminal's earliest receiving date opens on D+4. The box waits on your yard, in detention, and the drayage saving is consumed before it is banked.
3. The box is not the right grade. Food, pharmaceutical or apparel exports need a clean, dry, odour-free unit; a box that has just carried machine parts may be greasy or slightly dented, and the refusal sometimes lands at the export gate rather than at request time.
4. The depot wants the unit back. Scheduled maintenance, fleet retirement, off-hire redelivery to a lessor: carriers flag specific container numbers for physical recovery, and no commercial argument overturns that flag.
5. The carrier is rationing empties. The most structural reason and the least intuitive, so it gets its own section. Importers who want out of that dependency look at equipment they control themselves — the trade-off is laid out in our comparison of SOC versus COC containers.
Your lane's direction decides more than your argument does
Container shipping permanently moves empty boxes because trade is unbalanced: regions that import more than they export accumulate units nobody needs locally, and exporting regions run short. The share of container movements performed empty is commonly estimated at around 20% of the total — an order of magnitude drawn from UNCTAD's maritime transport work, not a contractual figure. It reaches you through two channels: equipment imbalance surcharges, and the rate gap between headhaul and backhaul.
The practical consequence runs opposite to intuition. Where empties pile up, the carrier says yes, because a loaded export earns more than a repositioning move it would fund itself. Where empties are scarce, it wants to decide which exporter gets the unit, and your street-turn takes that decision away from it.
The regulatory backdrop also differs by market, and it matters more than it looks. In the United States, the Ocean Shipping Reform Act of 2022 and the FMC's subsequent billing rule set out who may be invoiced for detention, how quickly, and how long you have to dispute — which gives a documented switch date real leverage. In the UK and across the EU, detention remains purely contractual, so your only leverage is what the tariff and the booking confirmation say.
Three worked cases
The figures below are working assumptions consistent with observed US short-haul ranges; they vary by drayage provider, port and season.
Case 1 — the one that works. A 40' HC lands at Savannah carrying roughly 38,000 lb of packaged goods, stripped 40 miles inland on day four of a seven-day free period. A furniture exporter 18 miles away is booked with the same carrier, receiving window open. Without a street-turn: warehouse → depot leg at $420, gate-in lift $55, gate-out lift $55, depot → exporter leg at $420, so $950 spread across two shippers. With the street-turn: one 18-mile leg at $290 and no lifts. A $660 saving, less two extra chassis days at $35 — roughly $590 net.
Case 2 — the one the calendar kills. Same setup, but the export ERD opens four days later and the free period expires in between. Four detention days at $160 come to $640 against a theoretical $660 saving: a $20 gain carrying full operational risk. The correct call is to return the empty.
Case 3 — the one the box condition kills. Street-turn approved, unit rejected at the export gate for a bent roof rail. You pull a replacement empty on short notice ($420), move the rejected box to the depot ($420) and absorb two more detention days ($320): $1,160 more than a plain depot return. The countermeasure is one line of procedure — photograph all four walls and the roof rail at the import out-gate, and record every exception on the equipment interchange receipt, which decides who carries the damage.
Price the empty leg with everything else
Return drayage, depot lifts, chassis days and detention are landed-cost lines exactly like ocean freight and duty.
Run the calculation →Decided at booking, not at stripping
A street-turn is not rescued mid-flight; it is set up in advance. Three checks made when the export booking is placed decide the outcome: same carrier on both bookings, overlap between empty availability and the ERD, and a box grade that suits the export cargo. When all three are green the request almost always clears. When one is red, it burns time while the clock runs.
The habit worth building is to treat the empty return as a shipment in its own right, with a date, a budgeted cost and a named owner. In India the same logic applies with a local twist: boxes routed through a CFS or an inland container depot often have to touch that facility regardless, so the match-back is planned against the CFS calendar rather than the warehouse one. Either way, whether a provider can hold that matching as a standing process rather than a one-off favour is itself a selection criterion — covered in our guide to choosing a freight forwarder.
Frequently asked questions
Who actually approves a street-turn — my trucker or the ocean carrier?+
The ocean carrier, and only the carrier. On a carrier-owned (COC) box, the equipment control desk is the sole party that can move a unit from an import booking to an export booking. Your drayage provider, forwarder or NVOCC can build the match, propose it and chase it, but none of them can authorise it. A trucker who says "we'll street-turn it" without written approval is describing an intention, not a decision. Insist on the confirmation that the container number has been switched onto the export booking: that single message is what protects you both from a refusal at the terminal gate and from a detention clock that keeps running.
Does a street-turn really stop the detention clock earlier?+
It stops it at the administrative switch of the box onto the export booking — not at unloading, and not when the truck leaves your yard. That distinction is expensive: if the switch is recorded three days after your warehouse emptied the container, those three days usually remain billable. Carrier tariffs word this differently from one another, and some tie the stop to the physical gate-in at the export terminal instead. Get the agreed date written into the approval email. In the United States, the FMC Demurrage and Detention Billing Requirements rule (effective 28 May 2024) also gives you a defined window to dispute a charge, which makes a documented switch date directly useful rather than merely tidy.
What happens if the box is rejected at the export terminal gate?+
You end up with three drayage legs instead of two, an emergency empty pull for the exporter, and detention still running on the rejected box until it physically reaches a depot. Liability for the damage is settled through the chain of equipment interchange receipts: the last EIR signed without exception puts the damage on whoever held the box at that moment. Hence the only defence that reliably works — photograph all four walls and the roof rail at the import terminal out-gate, and get any exception written onto the outbound EIR before the truck leaves the gate.
Can a street-turn work between two different ocean carriers?+
Not in the general case. A container belongs to a carrier or to a lessor under contract with that carrier, and it cannot be loaded onto a competitor's vessel. Vessel-sharing alliances do not change this: they share slots, not container fleets. Two exceptions exist in practice. Shipper-owned (SOC) boxes, which you own or lease and therefore reassign freely. And bilateral equipment interchange agreements between carriers, which are rare, negotiated at head-office level, and never available to an individual importer on a one-off basis.
In the US, does the chassis complicate the arithmetic?+
Yes, and it is the most commonly missed item. In most US markets the chassis is supplied separately from the container — through a pool, a carrier allocation or your own fleet — and it runs its own per diem meter, typically in the $25–45 per day range depending on the pool and market. A street-turn keeps both the box and the chassis out longer than a straight depot return would, so a plan that saves two drayage legs can quietly add chassis days. Model the chassis line explicitly before committing; in most cases the drayage saving still wins, but the margin is thinner than the container-only calculation suggests.
