  "description": "Calculate air freight volumetric weight from carton dimensions using the IATA 6000 divisor, express 5000 divisor, or a custom carrier divisor.",

  "faq": [
    {
      "q": "What divisor should I use for air freight volumetric weight?",
      "a": "Use 6000 for standard IATA air freight unless your forwarder gives a different divisor. Use 5000 for international express courier shipments."
    },
    {
      "q": "What is the air freight volumetric weight formula?",
      "a": "Volumetric weight in kg equals length x width x height in cm x quantity divided by the divisor."
    },
    {
      "q": "Is air volumetric weight the same as chargeable weight?",
      "a": "No. Volumetric weight is compared against actual gross weight. The higher number is chargeable weight."
    },
    {
      "q": "Why is the 5000 divisor more expensive than 6000?",
      "a": "A lower divisor creates a higher volumetric weight from the same carton size, so courier pricing is stricter for light bulky cargo."
    },
    {
      "q": "Should I use product size or carton size?",
      "a": "Use the outer packed carton or pallet dimensions. Airlines and warehouses measure the freight as tendered, not the product inside."
    },
    {
      "q": "How do I know if cargo is volume-sensitive?",
      "a": "Divide actual gross weight by CBM. If the density is below about 167 kg/m3 for IATA air freight, volumetric weight will likely be higher."
