  "description": "Estimate air freight USD/kg rate bands by lane, service level, and chargeable weight without turning the page into a full quote, price, or landed-cost calculator.",
  "answer": "Air freight rates are usually quoted as a USD/kg band by lane and service level, then applied to chargeable weight after actual and volumetric weight are compared.",

  "faq": [
    {
      "q": "What does an air freight rates calculator estimate?",
      "a": "It estimates a planning USD/kg band for a lane and service level, then multiplies that band by chargeable weight."
    },
    {
      "q": "Is this a quote calculator?",
      "a": "No. It is intentionally a rate-band calculator. A quote also needs shipper address, consignee address, pickup, delivery, commodity, batteries, customs, and current capacity."
    },
    {
      "q": "Is this different from an air freight price calculator?",
      "a": "Yes. A price calculator adds shipment-level surcharges and fees. This page focuses on lane and service rate bands only."
    },
    {
      "q": "Why does chargeable weight matter for rates?",
      "a": "Air freight rates apply to chargeable weight, which is the higher of actual gross weight and volumetric weight."
    },
    {
      "q": "Why do larger shipments get lower USD/kg rates?",
      "a": "Forwarders and airlines often price 300 kg, 500 kg, and 1000 kg tiers more aggressively because larger consolidations use capacity more efficiently."
    },
    {
      "q": "Are these live market rates?",
      "a": "No. They are dated planning bands for ecommerce cargo and should be checked against a live forwarder quote before booking."
