  "description": "Estimate international freight planning bands across ocean FCL, ocean LCL, and air freight using lane assumptions, local charges, cargo size, weight, and a booking buffer.",
  "answer": "An international freight rate calculator should estimate a low-to-high planning band by mode, lane, chargeable size or weight, origin charges, destination charges, and a buffer because live quotes change before booking.",

  "faq": [
    {
      "q": "Is this international freight rate calculator showing live rates?",
      "a": "No. It shows planning bands based on lane and mode assumptions. Live freight quotes change with capacity, fuel, seasonality, surcharges, and booking week."
    },
    {
      "q": "Which freight modes does it compare?",
      "a": "It estimates ocean FCL, ocean LCL, and air freight bands, then adds origin charges, destination charges, and a planning buffer."
    },
    {
      "q": "How does it calculate air freight?",
      "a": "Air mode uses the higher of actual gross weight and volumetric weight at CBM x 167 kg, then applies the existing air freight lane rate bands."
    },
    {
      "q": "How does it calculate ocean LCL?",
      "a": "Ocean LCL uses W/M revenue tons, meaning the higher of CBM and gross weight divided by 1,000 kg, then applies the existing LCL lane bands."
    },
    {
      "q": "How does it calculate ocean FCL?",
      "a": "Ocean FCL uses the existing per-container ocean lane bands by 20GP, 40GP, or 40HQ and shows an effective per-CBM planning cue."
    },
    {
      "q": "What charges should I enter as origin and destination charges?",
      "a": "Enter handling, documentation, export or import local charges, CFS or terminal fees, and other quote line items outside the main freight linehaul."
    },
    {
      "q": "What should I use next after this calculator?",
      "a": "Use the specialist ocean, air, LCL, FCL, and quote tools to narrow the planning band into a bookable freight quote."
