What should you do when container tracking stops updating?
First confirm the container number, booking reference and last recorded event with the carrier or contracted forwarder. Distinguish an estimated movement from a confirmed handover and ask who currently has custody. A missing update does not by itself establish theft, physical loss or an insurance claim, but it can justify a documented operational enquiry.
Read the event, not only the map
Maersk's container-location guidance directs customers to its tracking service and support channel when a location cannot be resolved. The same practical principle applies to other carriers: use the actual provider's recognised channel rather than an unfamiliar tracking site supplied in an unsolicited message.
A ship-position display and a container event history answer different questions. Your goods may be awaiting loading, discharged, transferred to another service or already moving inland. Do not assume that a vessel's displayed position proves the container is aboard it. Ask for the event that supports that conclusion.
A useful escalation message
| Include | Why it helps |
|---|---|
| Container and booking references | Avoid investigating the wrong movement |
| Last confirmed event and timestamp | Establish the starting point |
| Expected next event | Explain the specific gap |
| Cargo sensitivity | Identify temperature, security or deadline concerns |
| Delivery contact and availability | Make the next handover practical |
Keep the request focused: “Please confirm whether container X was loaded on voyage Y and provide the last custody event.” A general complaint that tracking is poor is harder to resolve. Ask when the next update will be provided and who owns the follow-up.
Separate a data gap from an operational incident
Consider a fictional container whose public status remains at the export terminal after the vessel has departed. The carrier later confirms that it was rolled to another sailing. The immediate problem is revised transport planning, not evidence that the goods disappeared at sea. If a subsequent inspection finds damage, preserve the separate condition evidence and chronology.
For high-value or temperature-sensitive cargo, also establish what safeguards remain in place while location is being confirmed. Request appropriate information through authorised parties; avoid publishing container references, security arrangements or customer details in public forums.
Keep a claim-ready record without assuming coverage
Save original status messages and responses, not just the latest screenshot. Retain the booking, transport documents, seal records, collection appointments and delivery exceptions. If a loss or a material change becomes apparent, notify the relevant insurer in accordance with the policy and explain what is known, what is unconfirmed and what is being investigated.
Insurance does not generally become a location service, and an estimated arrival time is not itself a coverage promise. Read the shipment evidence-file guide, review cargo insurance information, and send the confirmed journey and cargo details when arranging cover.
Key takeaways
- Ask for a confirmed custody event, not just a ship position.
- Escalate through a verified carrier or forwarder channel.
- Preserve uncertainty honestly until the facts are established.
