What This Document Covers:

A complete inbound seal verification workflow capturing seal numbers, discrepancies, photographic evidence, and escalation decisions. 

Includes:

• Date / Time

• Vehicle Registration

• Booking Reference

• Documented Seal Number

• Seal Number Observed

• Seal Condition – ☐ Intact ☐ Broken ☐ Missing ☐ Tampered

• Photographed – ☐ Yes ☐ No

• Vehicle Admitted – ☐ Yes ☐ Held – Escalated

• Checked By

• Supervisor Notified (if held)

Why The Document Matters:

This log ensures seal integrity is verified at the earliest possible point—before the vehicle enters the yard—reducing risk, strengthening compliance, and preventing inbound errors. This document improves inbound accuracy, reduces receiving errors, and standardises dock safety. 

Operational Pain Points:

• Inconsistent seal verification

• Security risks from tampered or missing seals

• Compliance gaps with ADR and hazardous goods

• Inventory discrepancies caused by unverified seals

• Delayed investigations due to missing documentation

• Failed audits from incomplete seal records

• Poor photographic evidence for claims or disputes

Full Procedure:

• Record Date / Time of seal check

• Capture Vehicle Registration and Booking Reference

• Record Documented Seal Number from paperwork

• Record Seal Number Observed on the trailer/container

• Select Seal Condition (Intact, Broken, Missing, Tampered)

• Tick Photographed – Yes/No

• Decide Vehicle Admitted – Yes / Held – Escalated

• Enter Checked By (security/gatehouse staff)

• If held, complete Supervisor Notified

• Attach photographs for any discrepancy

All steps must be completed before the vehicle is admitted to the yard.

How This SOP Integrates With WMS:

Although seal verification occurs at the gatehouse, it directly supports WMS accuracy by:

• Ensuring seal numbers match booking and ASN data

• Preventing incorrect receipting of tampered loads

• Strengthening audit trails for inbound discrepancies

• Supporting claims, investigations, and inventory adjustments

• Linking seal integrity to load accuracy and dock to stock workflows

Real World Errors This SOP Prevents:

• Incorrect seal numbers recorded

• Tampered seals entering the yard unnoticed

• Missing photographic evidence for disputes

• Hazardous loads admitted without verification

• Failed audits due to incomplete seal logs

• Inventory shortages linked to unverified seals

• Escalation delays during security incidents

Frequently Searched Operational Questions:

How do I verify trailer seals in warehouse inbound operations?

Problem: Seal checks done inconsistently.

Cause: No structured seal verification log.

Solution: This document provides a complete seal check workflow including condition, numbers, and escalation.

What should I do if a trailer seal is broken or tampered?

Problem: Security incidents mishandled.

Cause: No escalation process.

Solution: The log includes “Vehicle Admitted / Held – Escalated” and supervisor notification.

How do I compare documented vs observed seal numbers?

Problem: Incorrect seal numbers recorded.

Cause: No formal comparison step.

Solution: The form captures both numbers side by side.

Why is photographic evidence important for seal discrepancies?
