    },
    {
      "q": "How does it calculate chargeable weight?",
      "a": "The calculator converts dimensions to volumetric weight, compares that with actual gross weight, and uses the higher number."
    },
    {
      "q": "Does this include customs duty and taxes?",
      "a": "No. Customs duty, import tax, MPF, destination delivery, and warehouse handling are separate landed-cost items."
    },
    {
      "q": "What divisor should I use?",
      "a": "Use 6000 for standard air freight and 5000 for express courier unless your forwarder gives a different rule."
    },
    {
      "q": "Why can a small shipment cost more than the math suggests?",
      "a": "Air freight has fixed handling and paperwork costs, so forwarders often apply an 80 to 200 USD minimum charge for small shipments."
    },
    {
      "q": "How close is this to a real air quote?",
      "a": "For general cargo on stable lanes, a weight x rate model is often within 10 to 20 percent before destination and customs charges."
