  "description": "Calculate air freight chargeable weight by comparing actual gross weight against volumetric weight using the 6000 air cargo divisor, 5000 express divisor, or a custom divisor.",
  "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.",

  "faq": [
    {
      "q": "How is air freight chargeable weight calculated?",
      "a": "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."
    },
    {
      "q": "What divisor should I use for air freight?",
      "a": "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."
    },
    {
      "q": "Is chargeable weight the same as volumetric weight?",
      "a": "No. Volumetric weight is only one side of the comparison. Chargeable weight is the higher of volumetric weight and actual gross weight."
    },
    {
      "q": "Should I enter product dimensions or carton dimensions?",
      "a": "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."
    },
    {
      "q": "Why is my air freight charged above actual weight?",
      "a": "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."
    },
    {
      "q": "Does the calculator include airline minimum charges?",
      "a": "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."
