A truck can reach the correct building and still be unable to unload. A missing inbound reference, an unconfirmed appointment or the wrong unloading arrangement can interrupt the final stage of an otherwise well-planned import shipment.
1. Separate an appointment from a delivery estimate
A warehouse delivery appointment is the receiving facility’s agreed arrangement for an inbound load. It may specify a time slot, arrival window, check-in code and unloading method. An ETA from the carrier is a planning estimate; it does not establish warehouse acceptance.
Use three distinct statuses in your shipment record: requested, confirmed and dispatched. Avoid dispatching a truck on the assumption that an unanswered request has been accepted. If a facility operates without appointments, obtain its current receiving instructions and record that arrangement instead.
This guide is a buyer’s coordination checklist. Requirements differ by facility and service, so the receiving site’s written instructions should control the booking.
2. Confirm the actual receiving location
The buyer’s registered address, billing address and warehouse gate may be different. Ask for the precise receiving address, site name, inbound entrance and any routing restrictions that affect the planned vehicle.
- Warehouse name, site code and complete address;
- Gate or entrance used for inbound freight;
- Receiving contact and a working phone number;
- Receiving hours, closed days and site-local time zone;
- Vehicle access restrictions and safe waiting arrangements;
- Whether a separate security check-in is required.
Do not rely only on a map pin or an old delivery receipt. A facility can change its inbound gate, operator or appointment process while keeping the same street address.
3. Match references to the warehouse’s inbound record
A carrier’s shipment number may not be the reference the warehouse needs. Obtain the purchase order, advance shipment notice or warehouse inbound number required for that particular facility.
As one provider-specific example, Flexport’s warehouse scheduling instructions describe using an inbound or PO reference, carrier contacts and trailer or container details in its appointment process. That illustrates why booking identifiers should be agreed with the receiver rather than inferred from a bill of lading.
For multiple purchase orders, ask whether they can share one appointment and how they should appear in the booking. For a split delivery, obtain instructions before sending only part of the order. Do not assume that a warehouse accepts every combination.
4. Declare how the cargo will arrive
Give the receiving team final packaging data rather than a rough volume estimate. The unloading plan for floor-loaded cartons can differ substantially from a palletized delivery.
- Container, trailer or vehicle type;
- Palletized or floor-loaded cargo;
- Pallet count, carton count and packaging levels;
- Final dimensions and gross weight as required;
- Non-stackable, oversized or unusually heavy items;
- Any approved product-specific handling needs;
- Whether mixed SKUs require a specific unloading sequence.
If the supplier changes the packaging after the appointment request, update the receiver and carrier. An appointment based on pallets should not silently become a floor-loaded container delivery.
5. Agree the unloading method and equipment
Live unloading
The vehicle remains at the site while cargo is unloaded. Confirm who unloads, what equipment and labor are available, and how the receiving team handles an arrival outside the agreed window.
Drop arrangement
The container or trailer is left for later unloading where that service is available and approved. Confirm the authorized location, expected completion notification, equipment responsibility and collection arrangements.
Vehicle and site compatibility
Ask whether the site has a suitable dock, forklift or other equipment for the planned cargo. If a liftgate or special handling is needed, it should be arranged before dispatch. Never assume that the driver can provide equipment or labor outside the agreed service.
These are operational choices, not interchangeable labels. The receiving facility and carrier must both confirm the applicable arrangement.
6. Check readiness before asking for a final slot
For an ocean import, warehouse acceptance is only one part of readiness. Confirm that cargo release, customs status, physical availability and the planned inland movement support the proposed delivery date. A warehouse appointment does not clear a hold at the port.
For container deliveries, coordinate the receiving plan with the applicable pickup and empty-return obligations. A warehouse may have a suitable slot that is still impractical for the trucker or container cycle.
Keep uncertainty visible. If discharge or release is pending, communicate a provisional plan and agree when the slot must be reconfirmed. Do not present a vessel ETA as a guaranteed warehouse arrival.
7. Give the driver one current instruction sheet
Once the appointment is confirmed, send a concise instruction sheet that combines the information needed at the gate. Avoid making the driver search through several forwarded emails with conflicting references.
- Receiving address and inbound gate;
- Confirmed date, time window and site-local time zone;
- Appointment number or check-in code;
- Shipment, container or trailer reference;
- Required PO, ASN or warehouse inbound identifiers;
- Cargo count and approved unloading arrangement;
- Required documents and contact person;
- Late-arrival or access-problem escalation contact.
Maersk Ground Freight’s appointment guidance emphasizes accurate recipient contacts and access instructions, while noting that scheduling and confirmation vary by service model and region. Check the specific carrier and facility process for your load.
8. Control changes instead of forwarding every update
Assign one person to own the appointment record. When a truck is delayed or cargo data changes, that person should identify the impact, contact the receiving site and carrier, and distribute one updated confirmation.
Confirm whether the original appointment remains valid, needs amendment or must be cancelled and rebooked. Record any applicable waiting, rescheduling or additional service terms directly with the provider; there is no universal fee or grace period.
A useful update states the old plan, new estimate, reason, confirmation status and next action. Tell every affected party when a slot is superseded so the warehouse does not wait for one truck while the carrier operates to another plan.
9. Pre-dispatch sign-off
- The receiving site and gate are verified;
- The required inbound references match the cargo;
- The appointment is confirmed, or the facility’s no-appointment process is documented;
- Cargo quantities and packaging reflect the final shipment;
- The unloading method, labor and equipment are agreed;
- Release and availability support dispatch;
- The driver has one current instruction sheet;
- A named person owns exceptions and rebooking;
- The receiver and carrier have the same latest version.
After delivery, save the receiving record and any exception notes. If count or condition differs from the plan, use a separate receiving-discrepancy workflow rather than editing the original booking to hide the difference.
10. FAQ
Does an appointment guarantee immediate unloading?
No. It confirms the receiving arrangement subject to the site’s process and actual conditions. Ask how queues, late arrivals and unloading exceptions are managed.
Who should book: the importer, forwarder or trucker?
The parties should explicitly agree ownership. Some facilities require the carrier to book through a designated portal; others coordinate with the buyer or warehouse account holder.
Can several POs use the same slot?
Only if the receiving facility accepts that structure and the references are included correctly. Rules should be checked before the truck is assigned.
What if the delivery date changes after booking?
Notify the appointment owner promptly and obtain an amended or replacement confirmation where required. An updated ETA alone does not update the warehouse’s slot.
