We'll watch your containers, so you don't have to.
DwellZero checks the Last Free Day, holds and availability of every container you track at 162 port and rail terminals in the US and Canada, and alerts you before the LFD turns into demurrage.
- DispatchersPlan pickups around the Last Free Day.
- TruckersSee availability and holds before the trip.
- Freight forwardersWatch deadlines across many terminals.
- ImportersKnow when a box is available or held.
- DevelopersConnect container status to your own systems.
Why it matters
Know the LFD before it costs you.
DwellZero reads the Last Free Day from the terminal itself and reminds you two days out, one day out and on the day.
Example only. Demurrage rates vary by terminal and line.
