Chain of Custody Tracking for Freight: Proving Where a Load Was and Who Had It

By the Sentrick Cargo team · Published October 3, 2026

A typical shipment passes through many hands between origin and destination: a shipper's dock, a carrier, perhaps a broker, a drop yard, a cross-dock, a second carrier, a warehouse, and finally a receiver. Each handoff is a moment of transferred responsibility. When a load disappears, arrives short, or shows signs of tampering, the first question is always the same: who had it, where, and when? Chain of custody tracking is the discipline of answering that question with evidence rather than guesswork.

The stakes are rising. According to Verisk CargoNet's analysis of 2025 activity, estimated cargo theft losses reached about $725 million in 2025 — roughly 60% higher than in 2024 — and the average value per theft rose to about $273,990. Many of the most damaging schemes, from fictitious pickups to strategic theft, exploit handoffs and paperwork rather than the open highway.

What chain of custody means for freight

In freight, chain of custody is a continuous, verifiable record of a shipment's location, condition, and responsible party from pickup to delivery. At any point in the journey, it should answer four questions:

• Where was the load?
• Who was responsible for it — which carrier, driver, or facility?
• What condition was it in — sealed, intact, at the right temperature?
• What changed, and when?

Bills of lading and delivery signatures capture the start and the end. Real chain of custody fills in everything in between.

Where custody usually breaks

• Pickup identity. The truck at the dock is not always the carrier you hired. Fictitious pickups and double brokering break the chain before the load even moves.
• Unattended dwell. Trailers sitting in yards, truck stops, or drop lots over a weekend are a well-known target for theft at rest.
• Handoffs and transloads. Cross-docks and interchanges are where counts get muddled and responsibility becomes ambiguous.
• Silent gaps. Periods with no data — a dead device, a jammed signal, a tracker left in the cab — leave windows nobody can explain.

The building blocks of custody tracking

• Verified pickup. Confirm carrier, driver, tractor, and trailer at the dock against what was booked, and record it.
• Continuous location. A tracker that travels with the freight or trailer, not just the tractor, so the cargo's path is known even if equipment is swapped.
• Condition events. Door open and close, seal status, shock, light inside a sealed container, and temperature for reefer loads — each stamped with time and place.
• Handoff records. Every transfer logged with who released the load, who received it, and its condition at that moment.
• Gap detection. An alert when a device stops reporting, so a silent period becomes an event rather than a mystery.

From a log to an early warning

A custody record is valuable after an incident, for claims and investigations. It is far more valuable when it raises a flag while there is still time to act. That is where behavior matters. A door opening at the consignee's dock is routine; the same door opening at an unscheduled stop at 2 a.m. is not. A short stop at a fuel island is normal; a long stop off-route followed by a signal loss is a pattern worth an immediate call. Comparing each shipment's behavior to its plan, and to what normally happens on that lane, turns a passive log into an early warning system.

Why it pays off beyond theft

Strong chain of custody also simplifies insurance claims, speeds up disputes between shippers, carriers, and receivers, supports compliance for regulated goods such as pharmaceuticals and food, and gives customers confidence that their freight is being handled with care.

How Sentrick Cargo approaches it

Sentrick Cargo combines tracking, condition sensing, and behavioral AI to keep a continuous, time-stamped record of each shipment — and to watch that record for patterns that do not fit: unexpected stops, door events in the wrong place, route deviations, and silent gaps. Risk is expressed on one clear five-level status — Safe, Caution, Alert, Danger, SOS — so operations teams know which loads need attention now.

The takeaway

Every load changes hands, and every handoff is a chance for responsibility to blur. Chain of custody tracking keeps that responsibility clear from pickup to delivery. Paired with behavioral monitoring, it does more than prove what happened — it helps stop it from happening.
