Air Freight Chargeable Weight Calculator
Answer: Air freight chargeable weight is the higher of actual gross weight and volumetric weight, where volumetric weight is length x width x height in centimeters x quantity divided by the carrier divisor.
Air freight chargeable weight is the higher of actual gross weight and volumetric weight; volumetric weight equals packed length x width x height in centimeters x quantity divided by the carrier divisor, usually 6000 for standard air freight.
How the calculation works
Enter the packed carton dimensions, carton quantity, actual weight per carton, and the divisor from your carrier quote. The calculator converts dimensions to centimeters, calculates total CBM, calculates volumetric weight, converts actual weight to kilograms if needed, then selects the higher number as chargeable weight.
For standard air freight, use divisor 6000:
volumetric weight kg = length cm x width cm x height cm x quantity / 6000
For express courier and some premium services, use divisor 5000:
volumetric weight kg = length cm x width cm x height cm x quantity / 5000
Example: 12 cartons at 60 x 45 x 40 cm and 18 kg each have 216 kg actual weight. Volumetric weight at divisor 6000 is 216 kg, so the air chargeable weight is 216 kg. With divisor 5000, volumetric weight becomes 259.2 kg, so the shipment is billed at 259.2 kg.
FAQ
What is air freight chargeable weight? Air freight chargeable weight is the billable weight used in an air cargo quote. It is the higher of actual gross weight and volumetric weight.
What divisor should I use for air freight? Use 6000 for standard air freight unless your airline or forwarder gives a different divisor. Use 5000 for express courier, parcel express, or premium air services when the carrier quote states 5000.
Why does air freight use volumetric weight? Aircraft capacity is limited by both weight and space. Light bulky cartons can fill aircraft space before reaching the aircraft weight limit, so carriers convert volume into a billable weight.
Should I enter one carton or the whole shipment? Enter one packed carton size and the quantity when all cartons are identical. If you have mixed carton sizes, calculate each carton type separately and add the chargeable weights.
Should actual weight include packaging? Yes. Use gross packed weight, including cartons, inner packaging, pallets, and labels if the shipment is palletized.
What density makes cargo volume-sensitive? With the 6000 divisor, cargo below about 167 kg per CBM is usually billed by volume. With the 5000 divisor, cargo below about 200 kg per CBM is usually billed by volume.
Does this include air freight cost? No. This tool calculates chargeable weight only. To estimate cost, multiply the result by your USD/kg rate and add minimum charges, fuel surcharge, security, pickup, clearance, and delivery.
Divisor comparison
| Service type | Common divisor | Density threshold | Best used for |
|---|---|---|---|
| Standard air freight | 6000 cm3/kg | 167 kg/CBM | Forwarder airport-to-airport or door-to-door air cargo |
| Express courier | 5000 cm3/kg | 200 kg/CBM | DHL, FedEx, UPS-style small parcel and express shipments |
| Custom forwarder quote | Quote-specific | Varies | Contract rates, oversized cargo, special lanes |
Chargeable weight comparison
| Measurement | Formula | When it controls billing |
|---|---|---|
| Actual weight | Gross weight per piece x quantity | Dense cargo above the divisor density threshold |
| Volumetric weight | L x W x H cm x quantity / divisor | Light bulky cargo below the divisor density threshold |
| Chargeable weight | Higher of actual and volumetric | Always the number used for air freight rating |
Dated facts
- As of May 2026, most China to US standard air freight quotes still use the 6000 cm3/kg divisor for general cargo.
- As of May 2026, express courier and small parcel air services commonly use the 5000 cm3/kg divisor, which bills bulky cartons more heavily than standard air freight.
- As of May 2026, China to US air freight quotes for general ecommerce cargo often start from 100 kg chargeable weight, even when the calculated weight is lower.
- As of May 2026, China to US air freight for non-dangerous goods commonly prices around USD 4.50 to 6.50/kg for sub-500 kg shipments, before remote delivery, battery, oversize, and customs-related charges.
Frequently asked questions
- How is air freight chargeable weight calculated?
- Calculate actual gross weight, calculate volumetric weight from packed dimensions, then bill on whichever is higher. Standard air freight commonly uses the 6000 divisor in cm, while express courier often uses 5000.
- What divisor should I use for air freight?
- Use 6000 for general IATA-style air freight unless your forwarder specifies another divisor. Use 5000 for express courier or premium air services when the quote says so.
- Is chargeable weight the same as volumetric weight?
- No. Volumetric weight is only one side of the comparison. Chargeable weight is the higher of volumetric weight and actual gross weight.
- Should I enter product dimensions or carton dimensions?
- Enter the outer packed carton or pallet dimensions. Airlines and warehouses measure the shipment as tendered, including master cartons, void fill, and pallet height if palletized.
- Why is my air freight charged above actual weight?
- Light bulky cargo consumes aircraft space before it reaches the aircraft weight limit. If density is below about 167 kg per CBM with a 6000 divisor, volumetric weight will exceed actual weight.
- Does the calculator include airline minimum charges?
- No. It calculates billable weight only. Air quotes may still apply a minimum shipment charge, fuel surcharge, security fee, pickup, customs clearance, and delivery cost.
