Declared packing CBM
Calculated from outside package dimensions. Use it for packing list discussion and freight quotation basis.
Buyer Tool
Estimate container quantity from a mixed cargo list, compare 20GP, 40GP and 40HQ, then send the loading basis with your RFQ.

Calculated from outside package dimensions. Use it for packing list discussion and freight quotation basis.
For cylindrical rolls, the estimator applies a factory-experience correction by roll diameter before comparing container capacity.
Metal-heavy cargo uses a lower payload factor. Oversize packages still need supplier and freight-forwarder confirmation.
Declared packing CBM = length x width x height x quantity
Loading planning volume = diameter x diameter x roll width x quantity / (1 - correction)
Estimated containers = max(volume count, weight count) across 20GP, 40GP and 40HQ.
Sourcing resources
You need outside package dimensions, quantity and gross weight for every roll, bundle, carton or pallet. Mixed products should be entered as separate cargo lines.
No. Packing CBM comes from the outside package dimensions. Loading planning volume adds an empirical correction for cylindrical rolls to estimate container quantity.
Larger rolls often create more unusable space against container dimensions and loading patterns. The correction is a procurement estimate based on factory loading experience.
No. It prepares container quantity, CBM and gross-weight information that a freight forwarder can use for a freight quotation.
Yes. Enter the proposed container types and quantities to compare aggregate volume and payload utilization. Final item allocation still requires the supplier loading plan.
No. Package dimensions, container door size, loading direction, pallets, securing and handling space can still affect the final result.
