  "description": "Compact exact-match calculator for checking chargeable weight in air freight quotes. Compare total actual gross weight with volumetric weight, audit the quoted chargeable kg, and estimate linehaul cost.",
  "answer": "Chargeable weight for air freight is the higher of actual gross weight and volumetric weight, where volumetric weight equals packed volume in cubic centimeters divided by the air freight divisor.",

  "faq": [
    {
      "q": "What does this calculator do?",
      "a": "It compares total actual gross weight with volumetric weight and returns the air freight chargeable weight. It also checks the difference from a quoted chargeable weight if you enter one."
    },
    {
      "q": "What is the canonical page for this topic?",
      "a": "The canonical general calculator is /tools/air-freight-chargeable-weight-calculator/. This exact-match page is a compact quote-audit variant for the phrase \"chargeable weight air freight calculator\"."
    },
    {
      "q": "What divisor should I use?",
      "a": "Use 6000 cm3/kg for standard air freight planning unless the quote or rate card states another divisor. Use the exact divisor from the quote when auditing a forwarder calculation."
    },
    {
      "q": "Should I enter total weight or per-carton weight?",
      "a": "This compact variant uses total actual gross weight for the full shipment. Include products, cartons, pallets, wrap, and export packing."
    },
    {
      "q": "Why does the quoted chargeable weight differ?",
      "a": "Forwarders may round dimensions, round each piece before summing, apply a minimum chargeable weight, use a different divisor, or add oversized-piece rules."
    },
    {
      "q": "Does this calculate the final air freight invoice?",
      "a": "No. It calculates chargeable weight and an optional linehaul estimate. Final invoices can include fuel, security, pickup, customs, destination delivery, minimums, and accessorial fees."
    },
    {
      "q": "Is chargeable weight the same as volumetric weight?",
      "a": "No. Volumetric weight is the volume-based side of the comparison. Chargeable weight is the higher of volumetric weight and actual gross weight."
