What a 40ft High Cube Container is used for
A 40HC suits light, bulky cargo and tall items: furniture, foam products, packaged consumer goods or anything that can use the extra 30 cm of height. For the same freight rate, it often carries more cartons than a standard 40ft.
Cartons rarely fill the full 76.4 m³. Fixed carton sizes leave gaps against the walls and ceiling, and stacking limits, fragile goods and the payload reduce what fits. That is why a carton-by-carton load plan is more reliable than dividing the container's CBM by the carton CBM.
