Chargeable Weight
Chargeable weight is the number an air carrier bills on: the greater of a shipment's actual gross weight and its volumetric weight. Volumetric weight in kilograms is length times width times height in centimeters divided by 6,000 per piece; in pounds it is length times width times height in inches divided by 166. A pallet of foam that weighs 200 kg but measures 120 by 100 by 150 centimeters has a volumetric weight of 300 kg, so it bills at 300 kg. Multiply the chargeable weight per piece by the piece count for the shipment total.
Why it matters
Aircraft run out of space before they run out of lift, so carriers price cube as well as mass. Light, bulky freight can bill at two or three times its scale weight, and the gap only shows up on the invoice if nobody ran the formula first. Chargeable weight also decides whether air makes sense at all: once the volumetric number climbs, ocean LCL priced per cubic meter usually wins.
When to use it
Run chargeable weight on every air shipment before requesting a quote, and quote in the unit the carrier bills in. Package to reduce cube: goods built tight on a pallet can bill at a fraction of the chargeable weight of the same goods loose in oversized cartons. Express parcel carriers use a different divisor (often 5,000), so do not reuse an air freight number for a courier shipment.
How Warp thinks about it
The Warp international air freight calculator turns pieces, dimensions, and weight into chargeable weight in either unit, then prices it against captured Asia to US lane rates, each dated, before a live air freight quote returns the exact number for the shipment. Warp quotes the flight, airport recovery, clearance coordination, and door delivery as one figure, so the chargeable weight you compute is the one the quote is built on.
