A container capacity estimate is a starting point for a freight enquiry, not a loading guarantee. External package dimensions, gross weight, stackability and access at both ends affect the transport plan. Use the same units when comparing freight quotes.
Measure the shipping unit, not only the product
Record the outside length, width and height of each packed unit. Include pallets and protective packaging. If package sizes differ, prepare a separate line for each size rather than multiplying one average dimension by the total quantity. Label dimensions with their unit so centimetres and metres are not confused.
Separate volume from loading feasibility
The simple volume calculation below does not account for door clearance, weight distribution, gaps or stacking restrictions. A package can fit within the nominal volume and still be unsuitable for a proposed loading arrangement. Confirm lifting needs, orientation and whether other cargo can be placed above it.
Compare quotes with the same scope
State pickup and delivery locations, readiness dates, cargo description and required transport stages. Clarify which handling, documentation and destination charges are included. Do not compare a port-to-port figure with a door-to-door quote as though they cover the same service. Ask for the final loading and service scope to be confirmed.
Check each stage| Stage | What to check | Useful outcome |
| Packing | Outside dimensions and package count | A clear packing list |
| Weight | Gross weight including packaging | A usable cargo weight |
| Handling | Stackability and lifting restrictions | A loading constraint list |
| Quote | Locations, dates and service stages | Comparable freight scope |
