  "description": "Quote-audit companion for calculating air freight chargeable weight by comparing actual gross weight with dimensional weight using a 6000, 5000, or custom divisor.",
  "answer": "Air freight chargeable weight is the higher of actual gross weight and dimensional weight, which is why light bulky cargo may bill above scale weight.",

    {
      "q": "What divisor should I use?",
      "a": "Use 6000 cm3/kg for standard air freight unless the quote states otherwise. Use 5000 for many express or parcel-style services."
    },
    {
      "q": "What is actual gross weight?",
      "a": "Actual gross weight is the scale weight of the packed shipment, including product, cartons, pallets, and packaging."
    },
    {
      "q": "What is dimensional weight?",
      "a": "Dimensional weight converts shipment volume into kilograms so bulky cargo pays for aircraft space."
    },
    {
      "q": "Why is my chargeable weight higher than actual weight?",
      "a": "Your cargo is likely below the density threshold for the selected divisor, so dimensional weight exceeds actual gross weight."
    },
    {
      "q": "Can I use this for quote checks?",
      "a": "Yes. Use it to sanity-check a forwarder quote, then confirm carrier rounding, minimums, and lane-specific surcharges."
