CONPDS CHECKER

Container Stuffing & Unstuffing Operational Evidence

Used by shippers, freight forwarders, NVOCCs, depot operators handling stuffing-on-behalf, and cargo insurers across Europe, Africa, Australia and the Middle East — including operators on routes where cargo damage and contamination claims are routinely contested.
ConPDS Checker captures structured pre-load, loading-sequence, sealed-condition, and devanning evidence that supports cargo damage and contamination claim review — every photo linked to the validated container number, the seal serial, and the responsible operator at the moment of capture. Exact evidentiary requirements follow the contract.

Replace WhatsApp photos and email attachments with a structured stuffing and devanning record that supports claim review, contamination disputes, or a cargo insurer's request for evidence months after the shipment was delivered.

No obligations — reply within 1 business day · Checker adapts to your stuffing operation — loading site, subcontractor model, and cargo insurer requirements all shape the workflow.

Why Cargo Damage Claims Are Harder Without Stuffing Evidence

Cargo damage and contamination claims often turn on whichever party can produce structured evidence first. When pre-stuffing photos live in a warehouse manager's phone, the loading sequence was never captured at all, and the seal photo is a JPEG attached to an email three days later, the operator with the weakest evidence chain is typically at a disadvantage — regardless of which party caused the damage in transit. Exact outcomes still follow the contract and applicable rules.

In many stuffing operations, documentation is still

Captured on warehouse staff or subcontractor phones — no container link
Missing the pre-stuffing condition baseline — only the finished load was photographed
Missing the loading sequence — only the closed-door shot is in the file
Seal serial photographed without timestamp or device-recorded GPS when available — weak at audit
Devanning photos sent by WhatsApp from the consignee — stripped of metadata

The result when a cargo claim arrives

Contamination claim — no pre-stuffing condition baseline to disprove residue
Damage claim — no loading-sequence photos to show pre-transit cargo state
Seal-tampering claim — no seal serial photo at load and at devan to compare
Insurer review favours the party with the stronger evidence chain
Cargo damage claims are won and lost at stuffing and devanning, not in the claim-handling office. For the broader playbook, see how to document container stuffing for cargo damage claims →

A Structured Stuffing and Devanning Workflow — From Empty Container to Container-Linked Record

ConPDS Checker guides cargo handling documentation around the four moments claim review typically turns on: pre-stuffing condition, loading sequence, sealed-container baseline, and devanning state. These are recommended capture points — not enforced photo sequences.

01
Pre-Load
02
Loading
03
Sealed
04
Devanning
Step 01 — Pre-Load

Capture the Empty-Container Condition Before Stuffing Begins

Warehouse or stuffing-site staff photograph the empty container interior — floor, walls, ceiling, corners, and doors — under the validated container number. The pre-stuffing baseline documents that the container was clean, dry, and undamaged before loading, supporting review of contamination-from-previous-load arguments when a cargo claim is raised.

Step 02 — Loading

Photograph the Loading Sequence as Cargo is Stuffed

Key stages of the loading sequence are captured under the same container record — packaging condition, cargo orientation, dunnage, lashing, and load distribution. The loading-sequence record documents the cargo's pre-transit condition and the loading discipline that cargo insurers and consignee parties evaluate when a damage claim arrives.

Step 03 — Sealed

Document the Sealed Container with Seal Serial Visible

After loading, the closed doors are photographed with the seal serial number clearly readable and the door bars in locked position — captured with the same container number, timestamp, and device-recorded GPS when available as the loading sequence. The sealed-container photo is the baseline that can travel with the bill of lading and the cargo insurance certificate.

Step 04 — Devanning

Document Devanning with Seal Photos Under the Same Case

At devanning, photograph the seal before it is broken when that evidence is needed for review. The Checker app can scan seal barcodes; the scan is linked to the relevant photo or case — that is not automatic continuity matching across load and devan. Interior and cargo-damage photos under the same container record produce a paired stuffing-and-devanning archive for claim review.

What Structured Stuffing and Devanning Documentation Typically Includes

A photo of a sealed container is incomplete without the pre-load baseline, the loading sequence, seal serial visibility, and a corresponding devanning set. ConPDS Checker supports capturing all four under one container reference, with timestamp and device-recorded GPS when available.

Pre-Load Condition Baseline
Empty-container interior photos — floor, walls, ceiling, corners — establishing the clean-and-dry baseline before stuffing begins.
Loading-Sequence Capture
Key stages of the load sequence — cargo packaging, orientation, dunnage, distribution — under one container record.
Seal Serial Visibility
Closed doors photographed with seal serial readable and door bars locked — the baseline that travels with the bill of lading.
Seal Photos at Devan
Seal photographed before breakage at devanning; optional barcode scan linked to the photo or case. Side-by-side load/devan comparison is editorial — not automatic continuity matching.
ISO-Validated Container Link
Every photo linked to an on-device OCR-validated container number with ISO 6346 check-digit verification — wrong recognition flagged for retake or manual entry.
Insurer-Ready Distribution
Structured exports or secure guest portal — every distribution event logged, chain of custody preserved end to end.

Ad-Hoc Stuffing Photos vs Structured Stuffing Documentation

Cargo insurers typically favour the party with the stronger structured evidence record. ConPDS Checker builds that record at the loading site and the devanning site without changing how warehouse staff or subcontractors actually work. Exact outcomes follow the contract.

✗ Ad-Hoc Stuffing Documentation
Photos in WhatsApp threads — not container or shipment linked
No pre-stuffing baseline — contamination from previous load is hard to rebut
No loading-sequence record — pre-transit cargo state cannot be reconstructed
Seal serial photographed without capture metadata — weak at audit
Seal photos at load and at devan live in different threads — hard to compare
✓ Structured Stuffing Documentation with ConPDS
Photos linked to ISO 6346-validated container records at capture
Pre-stuffing condition baseline captured before the first carton goes in
Loading sequence captured chronologically under one container record
Seal serial captured with timestamp and device-recorded GPS when available
Stuffing and devanning photos under one container number, retrievable in seconds

Frequently Asked Questions — Stuffing & Unstuffing Documentation

What is container stuffing and unstuffing evidence system?
Container stuffing and unstuffing operational evidence captures structured photographic evidence at every stage of cargo handling — pre-load container condition, the loading sequence, the sealed container with seal serial visible, and the devanning condition on the receiving end. Every photo is linked to the ISO 6346-validated container number with timestamp and device-recorded GPS when available, producing the matched evidence record that supports cargo damage and contamination claim review. Exact requirements follow the contract.
Who needs structured stuffing and unstuffing documentation?
Shippers, freight forwarders, NVOCCs, depot operators handling stuffing-on-behalf, and cargo insurers all benefit from a structured record of the container's interior state at load and at devan. Without it, a cargo damage or contamination claim often turns on whichever party can produce usable evidence first.
How does pre-stuffing documentation defend against contamination claims?
Many cargo damage claims allege contamination from a previous load. A pre-stuffing record showing the container floor, walls, ceiling, and corners in a clean and dry condition, captured with timestamp and device-recorded GPS when available at the loading point, is evidence that can close that line of argument in claim review. Without it, the operator often depends on the depot's pre-release condition certificate alone — which cargo insurers may not treat as sufficient on its own.
How is seal documentation captured at load and at devan?
After loading, the seal can be photographed showing the seal serial number clearly readable and the door bar in its locked position — captured with the same container number, timestamp, and device-recorded GPS when available as the loading sequence. The Checker app can also scan seal barcodes; the scan is linked to the relevant photo or case. At devanning, photographing the seal before it is broken is recommended editorial practice for side-by-side review — Checker does not automatically match seal continuity across load and devan.
Does it work in remote loading and devanning locations?
Yes. ConPDS Checker works fully offline. On-device OCR with ISO 6346 check-digit verification, photo capture, and record tagging all function without a network connection — wrong recognition is flagged for retake or manual entry. Photos queue on-device and synchronise automatically once connectivity is restored — reliable for inland loading sites, port-side stuffing operations, customer warehouses, and devanning at consignee facilities with intermittent or no signal.
How quickly can subcontractors and warehouse staff start capturing?
The mobile app runs on the smartphones warehouse staff and subcontractors already carry. For a standard deployment, teams can be operational within hours. Role-based access lets you enrol stuffing-site subcontractors with capture-only permissions and remove access just as quickly when the engagement ends.
Can the stuffing and unstuffing record be shared with cargo insurers and consignees?
Yes. Evidence can be exported as structured reports or shared via a secure guest portal scoped to specific containers or shipments. Guest portal access is granted and revoked by the operator, and every access event is logged — so the chain of custody from loading site through cargo insurer or consignee review is preserved end to end.
How is the data retained and is it privacy-by-design?
All data is stored on EU-hosted infrastructure with privacy-by-design and role-based access. Each operator runs in its own secure tenant with role-based access control. Retention is configurable per tenant — typically aligned with the cargo insurance policy period and contractual claim windows.
