In express parcel logistics, air cargo, and cross-country trucking, carriers do not just weigh your shipment on a scale -- they measure its physical volume. If a carton is large but light, freight bills are calculated based on Dimensional Weight (DIM), penalizing shippers who pack excess empty space.
1. The Mathematical Reality of the DIM Divisor
Most domestic express carriers use a volumetric divisor of 5,000 (cm³/kg):
Billable Weight (kg) = Max( Actual Scale Weight, (Length x Width x Height) / 5000 )
If your product occupies 25x20x15 cm (1.5 kg actual weight), placing it in a generic 35x30x25 cm stock carton artificially raises your billable weight to 5.25 kg -- more than triple your actual freight cost!
2. Right-Sizing Through Precision Die-Cutting
TopWay's custom CorruWay boxes are die-cut to the exact geometry of your packaged unit. By reducing excess interior void by just 20%, businesses typically experience:
- Immediate 18% to 27% reduction in commercial freight charges.
- Elimination of costly secondary void fill (plastic bubble rolls, styrofoam peanuts).
- Higher pallet density: 33% more cartons per standard 1200x1000mm industrial pallet.
