How to Set Up Sealing at Warehouse Dispatch?
Warehouse dispatch sealing SOP.
Direct answer
A warehouse-dispatch sealing process should verify the correct vehicle/tote/cage after loading, link the seal serial to the shipment record, have an authorized person apply the seal and complete number/integrity verification at the gate. The goal is not simply to attach a seal, but to turn the responsibility handover between warehouse and transport into a measurable control point.
What you will learn
Sealing should occur after loading is complete and the outbound unit is verified.
The serial number should be linked to the shipment/vehicle record at the same moment.
Application and gate verification should preferably be separate control points.
There should be an exception flow that blocks departure for broken/mismatched seals.
KPIs should measure errors, resealing and processing time, not only seal quantity.
Control objective of warehouse-dispatch sealing
After goods are picked and loaded into a vehicle/cage, the critical moment is when responsibility transfers from warehouse operations to the transport chain. Recording the seal serial at this handover helps establish the physical condition in which the unit was released.
The strongest process is not an uncontrolled flow where one person takes the seal, records it and approves departure alone. Where volume permits, loading closure and gate verification can be separate steps, allowing a wrong serial or partially applied seal to be caught before the vehicle leaves.
Warehouse-dispatch sealing role matrix
| Stage | Responsible role | Control |
|---|---|---|
| Loading complete | Warehouse/loading team | Correct load, correct vehicle/cage, closure ready |
| Seal issue | Authorized inventory/security role | Correct product and unused serial |
| Seal application | Authorized applicator | Correct route and full engagement |
| System record | Applicator or scanning system | Serial ↔ shipment/vehicle link |
| Gate check | Security/gate operator | Number + physical integrity |
| Departure | Gate system | No departure until controls pass |
Rules to include in a warehouse-dispatch SOP
- Which seal model is used for each load/vehicle type
- Who may access unused seal inventory
- Which system field captures the serial and at what moment
- Void procedure for defective or incorrectly selected seals
- How the vehicle is held when gate number/integrity checks fail
- Resealing authorization and old/new serial linkage
Warehouse-dispatch sealing flow
- 1
Close loading
After shipment verification, inspect the vehicle/cage closure point physically.
- 2
Issue and scan the seal
Capture the serial of the correct unused seal against the shipment record.
- 3
Apply the seal
Fully engage it through the correct route and perform a light physical confirmation.
- 4
Perform an independent gate check
Compare the expected serial with the physical number and seal integrity.
- 5
Record departure or exception
If satisfactory, close the departure event; otherwise place the vehicle/load in the exception flow.
Frequently asked questions
Should warehouse or security staff apply the seal?
There is no universal role. What matters is documented authorization, controlled seal inventory and, where practical, independent gate verification.
Should the seal number be written on the delivery note?
Depending on the operating model it may be stored in documents, WMS/TMS or both. The critical point is a unique link between physical serial and shipment record.
Is a second gate check necessary?
It depends on risk and volume, but independent number+integrity verification is a strong control for catching application errors before departure.
What should happen to a defective seal serial?
Do not use it; mark the serial rejected/voided and prevent accidental assignment to an active shipment.
What KPIs can be used for warehouse sealing?
Useful metrics include wrong-serial rate, resealing rate, seal+gate processing time, missing unused seals and handover mismatches.
