Why Freight Scanning Matters
Every item that enters an Australian carrier’s network—whether a carton, pallet, skid or bulky item—is scanned to determine its dimensions, weight, routing and chargeable weight.
These scans ensure freight is handled safely, billed accurately and allocated to the correct depot workflow and linehaul vehicle.
Understanding how freight scanning works helps businesses reduce reweigh charges, avoid delivery delays and prevent unexpected invoice adjustments.
What Is Cubic Weight (Volumetric Weight)?
Cubic weight, also known as volumetric or DIM weight, converts the space freight occupies into a billable weight.
Australian carriers use cubic weight to ensure large, lightweight items contribute fairly to vehicle space compared with dense, heavy freight.
Chargeable weight is the higher of cubic weight or actual dead weight.
- Cubic weight = (length × width × height in metres) × cubic factor
- Common cubic factors in Australia range from 250 to 333 kg per cubic metre
- Applied to cartons, pallets, skids and bulky freight
- Ensures fair pricing for space used in linehaul vehicles
What Is DIM Scanning?
DIM scanning stands for Dimensioning, Identification and Weighing.
It is an automated process that measures freight using lasers, infrared sensors or 3D imaging technology.
Most medium and large carriers in Australia use DIM systems to improve accuracy, efficiency and billing consistency.
- Exact length, width and height
- Actual weight
- Barcode or consignment identification
- Audit images for verification
- Time and location of each scan
How DIM Scanners Work Inside Depots
DIM scanners are positioned at key points within carrier depots, such as inbound docks, conveyor lines or outbound sortation zones.
Freight passes through the scanning zone or is placed on a scanning platform, where sensors record precise measurements.
Captured data is automatically matched against the booking information provided by the customer.
- Overhead lasers or cameras detect cubic size
- Industrial scales capture actual weight
- Barcodes link measurements to the consignment record
- Discrepancies trigger reweigh or reclass flags
- Audit photos may be stored for billing review
Depot Handling: What Happens After Scanning
Once scanning is complete, freight enters the depot’s internal handling workflow.
Handling processes differ depending on whether freight is cartonised, palletised or oversized.
- Cartons move through automated conveyor and sortation systems
- Pallets are handled using forklifts or pallet movers
- Bulky freight is manually assessed and staged
- Dangerous Goods undergo additional compliance checks
- Metro and regional freight are separated into different staging zones
- Linehaul loading is planned based on destination and weight distribution
Why Reweigh and Reclass Charges Occur
Reweigh and reclass charges occur when scanned dimensions or weights differ from what was declared at booking.
These charges are not penalties; they reflect the correct space, weight and handling required for the freight.
Most discrepancies are caused by measurement errors or freight changing shape during transit.
- Declared dimensions smaller than scanned size
- Pallet overhang increasing cubic footprint
- Unstable freight shifting during handling
- Cartons bulging or deforming under load
- Freight placed on oversized pallets
- Actual dead weight higher than declared
How to Avoid DIM and Reweigh Discrepancies
Accurate measurement and proper packaging significantly reduce billing disputes and unexpected charges.
Most reweigh issues are preventable with consistent preparation standards.
- Measure freight after wrapping, strapping or palletising
- Use correct pallet sizes and avoid overhang
- Select strong, stable pallets
- Stack cartons evenly to prevent bulging
- Use calibrated scales for weight
- Round dimensions up rather than down
- Avoid irregular or unstable freight shapes
How Freight Scanning Improves Delivery Accuracy
Freight scanning affects more than pricing; it improves delivery accuracy and safety.
DIM data helps carriers allocate freight to the correct vehicle, route it through the right network and balance loads correctly.
- Accurate allocation to metro or regional delivery networks
- Improved load balance in trucks and containers
- Reduced manual handling and safety incidents
- Stronger tracking visibility and event history
- More reliable POD capture and delivery confirmation
How QFM Helps with DIM Scanning and Audit Accuracy
QFM works with carriers that operate advanced DIM and weighing systems across Australian depots.
We help businesses reduce scanning discrepancies by reviewing freight profiles, packaging standards and recurring reweigh patterns.
Our team analyses measurement data, audit images and scan logs to ensure freight charges are accurate and transparent.
If you’re experiencing repeated reweigh or reclass charges, QFM can review your freight data and provide a strategy to reduce discrepancies and improve DIM accuracy.
