An exception is any shipment deviating from plan: a rolled container, a missed connection, a customs hold, an ETA sliding past the promised delivery week. Exception management is the working system for catching those deviations early and acting on them — and it's the practical payoff of all the visibility infrastructure described in our RTTV guide.
The exceptions that matter most
- Rolled cargo — the container didn't board its intended vessel (overbooking, weight cuts, schedule changes). Symptom: the "loaded" event never arrives.
- Missed transshipment connections — the box reached the hub but not the onward vessel; the single biggest driver of week-scale ETA swings.
- Customs & documentation holds — the clock keeps running while paperwork is resolved; caught late, this converts directly into demurrage.
- Late departures / port omissions — vessels skip or slide ports; your ETA moves without any event on the container itself.
- Silent shipments — no events for days when there should be some. Silence is an exception too, and the easiest to miss.
The workflow: detect → alert → act
Detect: exceptions surface as event gaps or plan-versus-actual divergence — a load event that didn't happen, an AIS position inconsistent with the schedule, an ETA past the delivery commitment. Detection has to be automatic; nobody re-checks 80 shipments daily.
Alert: the deviation goes to the person who owns the shipment — email or dashboard — with enough context to act: what changed, the new ETA, the affected reference.
Act: rebook, expedite, pre-clear, or simply re-promise the customer early. Almost every response is cheaper the earlier it starts; the same missed connection costs an email on day one and a demurrage invoice on day ten.
Making it stick
Teams that do this well keep it simple: one dashboard everyone trusts, alerts wired to the few events that matter (departed, transshipped, discharged, ETA moved, gone silent), and a habit of working the exception list instead of the full shipment list. That's the design behind Shyppy — statuses, ETAs and alerts across ocean, air and courier, so the exceptions find you instead of the other way round.
