Your dispatch team weighs a sealed carton at 18 kg. The transporter quotes freight on 24 kg. Before treating the difference as an error, check the space the carton occupies.
In part truckload, or PTL, shipping, your goods share vehicle space with other shipments. A large box of lightweight components can take up more room than a compact box of metal parts. Volumetric weight gives the transporter a way to account for that space.
For businesses checking PTL volumetric weight in India, the first step is to confirm the calculation in the carrier agreement. Then measure the shipment as it will actually travel.
Understand the three weight figures
Actual weight is the gross weight shown by the scale. Include the carton, protective material and anything else travelling with the goods. For a palletised unit, that means including the pallet and wrapping too.
Volumetric weight converts the package’s outside dimensions into a weight for pricing. Where the agreement uses a divisor, multiply length by width by height, then divide by the specified factor. Use the measurement units stated in that agreement.
Chargeable weight is the weight used to calculate the freight charge. A common approach compares actual and volumetric weight and uses the higher figure, subject to the service’s rounding and minimum billing rules. Confirm how your booking applies these rules.
Work through a hypothetical carton
Assume one sealed carton travels without a pallet. Its outside dimensions are 60 cm × 50 cm × 40 cm, and its gross weight is 18 kg. For this example only, assume the agreement specifies a divisor of 5,000 and uses the higher of actual and volumetric weight.
Volumetric weight = 60 × 50 × 40 ÷ 5,000 = 24 kg.
The comparison is therefore 18 kg actual weight against 24 kg volumetric weight. The chargeable weight is 24 kg before any applicable rounding or minimum billing rule. If the same carton weighed 32 kg, actual weight would determine the comparison instead.
The divisor of 5,000 is an illustration, not a PTC rate commitment or a universal PTL rule. A different agreed factor changes the result. Adding a pallet would also require fresh measurements and a new gross weight.
Measure the complete packed shipment
Measure after your team seals the carton and finishes packing. Product dimensions alone will miss the space taken by cushioning, corner guards or an outer crate.
Record the full outside length, width and height. For a palletised shipment, measure from the bottom of the pallet to the highest point. Include any overhang, bulging packaging or projecting protection when identifying the outermost dimensions.
For example, an 80 cm carton on a 15 cm pallet has an overall height of 95 cm if nothing projects above it. Weigh the complete unit, including the pallet, instead of estimating its weight.
For several packages of different sizes, record each size and its quantity separately. Ask whether the transporter calculates chargeable weight package by package or across the consignment. Keep photographs of the measurement points and the scale reading alongside your dispatch record.
Check that the packing team and the booking team use the same units. Entering a millimetre measurement into a centimetre field will produce a very different calculation.
Check the billing rules before booking
Ask the transporter to confirm the conversion factor, dimensional rounding, weight rounding and minimum charge. A minimum billable weight and a minimum freight amount are different conditions, so clarify which applies.
Also disclose whether the shipment can support another package on top. Handling restrictions may affect the quote even when your dimensions and weights are correct.
Review oversized packaging where the product allows it. Removing unnecessary empty space can reduce volumetric weight, but retain enough protection for the journey. Recalculate after any packaging change.
Use this shipment measurement checklist
- Count the cartons, crates or pallets travelling together.
- Measure each packed unit at its outermost points.
- Include pallet height, wrapping and protrusions.
- Record gross weight and label every measurement unit.
- Confirm the calculation, rounding and minimum billing terms.
- Save the measurements and photographs with the booking.
