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 the structured pre-load, loading-sequence, sealed-condition, and devanning evidence that closes the cargo damage and contamination claim before the dispute starts — every photo linked to the validated container number, the seal serial, and the responsible operator at the moment of capture.

Replace WhatsApp photos and email attachments with a structured stuffing and devanning record that survives a cargo damage claim, a contamination dispute, 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 Settle Against the Operator Without Stuffing Evidence

Cargo damage and contamination claims are settled on whichever party produces 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 cargo insurer settles the claim against the operator with the weakest evidence chain — regardless of which party caused the damage in transit.

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 GPS or timestamp — not defensible at audit

Devanning photos sent by WhatsApp from the consignee — stripped of metadata

A Structured Stuffing and Devanning Workflow — From Empty Container to Settled Claim

ConPDS Checker structures cargo handling documentation around the four moments a claim is actually settled on: pre-stuffing condition, loading sequence, sealed-container baseline, and devanning state with seal continuity.

Pre-Load

Sealed

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 establishes that the container was clean, dry, and undamaged before loading, closing the contamination-from-previous-load argument before the 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 establishes 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 GPS metadata as the loading sequence. The sealed-container photo is the baseline that travels with the bill of lading and the cargo insurance certificate.

Step 04 — Devanning

Document Devanning with Seal Continuity Verified

At devanning, the same seal is photographed before it is broken — establishing seal continuity through the voyage. The unstuffed container interior and any cargo damage observed are captured under the same container record, producing the matched stuffing-and-devanning evidence pair the cargo damage or contamination claim is settled on.

What Defensible Stuffing and Devanning Documentation Requires

A photo of a sealed container proves nothing without the pre-load baseline, the loading sequence, the seal serial visibility, and the matched devanning record. ConPDS Checker captures all four under one container reference, with the metadata cargo insurers and consignee counterparties actually rely on.

Ad-Hoc Stuffing Photos vs Structured Stuffing Documentation

Cargo insurers settle in favour of the party with the 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.

✗ Ad-Hoc Stuffing Documentation

✗ Photos in WhatsApp threads — not container or shipment linked

✗ No pre-stuffing baseline — contamination from previous load is undisprovable

✗ No loading-sequence record — pre-transit cargo state cannot be reconstructed

✗ Seal serial photographed without metadata — not defensible at audit

✗ No matched seal-continuity record between load and devan

✓ 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 GPS preserved end-to-end

✓ Matched stuffing-and-devanning evidence pair 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 GPS metadata preserved.

Who needs structured stuffing and unstuffing documentation? ▼

Shippers, freight forwarders, NVOCCs, depot operators handling stuffing-on-behalf, and cargo insurers all need a defensible record of the container's interior state at load and at devan. Without it, a cargo damage or contamination claim is settled on the basis of whichever party produces 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 GPS at the loading point, is the evidence that closes that line of argument. Without it, the operator depends on the depot's pre-release condition certificate — which the cargo insurer is rarely satisfied with on its own.

How is seal continuity captured and proven? ▼

After loading, the seal is photographed showing the seal serial number clearly readable and the door bar in its locked position — captured with the same container number, timestamp, and GPS metadata as the loading sequence. At devanning, the same seal is photographed before it is broken, establishing the matched seal-continuity record.

Does it work in remote loading and devanning locations? ▼

Yes. ConPDS Checker works fully offline. Container number recognition, photo capture, and record tagging all function without a network connection. 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.

Can subcontractors and warehouse staff use it without training? ▼

Yes. The mobile app runs on the smartphones warehouse staff and subcontractors already carry, with a capture flow designed to work without manuals or classroom sessions. 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 GDPR compliant? ▼

All data is GDPR compliant and stored on EU-hosted infrastructure. 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.
