  "description": "Calculate air freight volume weight from packed carton dimensions using the 6000 air freight divisor, 5000 express divisor, or a custom carrier divisor.",

    {
      "q": "What is the air freight volume weight formula?",
      "a": "Volume weight in kg equals length x width x height in centimeters x quantity divided by the carrier divisor."
    },
    {
      "q": "What divisor should I use for air freight?",
      "a": "Use 6000 cm3/kg for standard international air freight unless your forwarder gives a different divisor."
    },
    {
      "q": "When should I use the 5000 divisor?",
      "a": "Use 5000 for many international express courier shipments and any quote where the carrier explicitly gives a 5000 divisor."
    },
    {
      "q": "Is volume weight the final billable weight?",
      "a": "Not alone. Forwarders compare volume weight with actual gross weight and usually bill the higher number as chargeable weight."
    },
    {
      "q": "Should I enter product size or carton size?",
      "a": "Enter the outer packed carton, master carton, crate, or pallet dimensions because that is the space the carrier measures."
    },
    {
      "q": "How do I know if my cargo is volume-sensitive?",
      "a": "If actual weight density is below about 166.7 kg per CBM with a 6000 divisor, volume weight will usually exceed actual weight."
