Add your containers ahead of time. We log in before your chosen release and attempt to book an available appointment at your selected gate.
For Durban container transporters
Struggling to get a Durban port slot?
Let us handle the race for a booking.
When slots are scarce, getting a truck appointment becomes another job in itself. PortSlot attempts your Navis N4 booking as slots are released, so you don’t have to sit at the screen waiting.
Then R187.20 per booked container. No slot, no charge.
Slots depend on N4 availability. We can’t create slots or guarantee a booking.

The truck is ready.
The missing piece is a slot.
Limited booking slots leave transporters competing for the same appointments. PortSlot takes the release-time booking attempts off your hands, giving you more time to run your transport business.
Step away from the screen
Early morning or after hours, you don’t need to be at your computer for the release you’ve queued. We handle the attempt.
Know where things stand
Check each request on your dashboard. When a booking succeeds, your SMS includes the appointment number, and the booking is in your own N4 account.
A little setup. Less chasing.

Before you get started
A few things you might be wondering.
How does PortSlot help when Durban booking slots are scarce?
PortSlot logs in before your selected N4 release and attempts to book available slots for your containers as they open. You don’t have to make the attempt manually. It doesn’t create additional slots or guarantee availability; you only pay when an appointment is booked.
Who can use PortSlot, and which ports do you cover?
PortSlot is for transporters with their own registered account on the Durban Navis N4 truck appointment system. We currently support the Durban dispatch only. Choose from the available gates when adding your containers.
Can you guarantee me a slot?
No. Availability is controlled by N4 and other transporters are competing for the same appointments. If we don’t secure a booking, you aren’t charged.
Do I need to stay online while you try?
No. Once your request is queued, we make the attempt at your selected release time. You can check its status on your dashboard, and we send an SMS when a booking succeeds.
When does PortSlot attempt bookings?
Our scheduled release times are 01:30, 06:30, 09:30, 13:30, 18:30, 21:30 (SAST). You can add containers for a release today or tomorrow, at least 5 minutes before it starts. These are booking release times, not a promise of a particular truck appointment time.
Can I add more than one container?
Yes. You can enter up to 5 containers in one request, subject to your available credit and unused free booking. Each container is booked and charged separately.
How will I know a booking was made?
You get an SMS with the container and appointment number. The appointment also appears in your own N4 account and on your PortSlot dashboard.
How do payment and the free booking work?
Your company’s first successful booking is free. After that, load prepaid credit into your account. Each successfully booked container costs R187.20. Credit is set aside while requests are queued; failed or missed attempts aren’t charged. Your dashboard shows your balance and booking status.
Can I cancel a request?
Yes. Remove it from your dashboard before we start trying, which is 5 minutes before the selected release.
