  "faq": [
    {
      "q": "How do I estimate Australian customs duty?",
      "a": "For planning, multiply the customs value in AUD by the confirmed duty rate for the tariff classification, origin, and concession status. ABF or a licensed broker should confirm the final declaration treatment."
    },
    {
      "q": "How is GST calculated on Australian imports?",
      "a": "GST is generally 10% of the value of taxable importation, which includes customs value, duty, and transport and insurance to Australia, subject to exemptions and special rules."
    },
    {
      "q": "Does this calculator include luxury car tax?",
      "a": "Yes, as an optional planning field for vehicles. It uses the 2025-26 ATO thresholds and 33% rate above the threshold, but vehicle approval, exemptions, and final LCT value need official review."
    },
    {
      "q": "What fees can I add?",
      "a": "You can add import processing, port or terminal charges, broker fees, and other local clearance costs such as storage, inspections, permits, quarantine, or delivery-related charges."
    },
    {
      "q": "Can this replace ABF, ATO, or broker advice?",
      "a": "No. It is a shipment-planning calculator only. Classification, valuation, origin, concessions, GST exemptions, vehicle rules, and declaration data can change the final payable amount."
    },
    {
      "q": "Should I use AUD values?",
      "a": "Yes. The customs value and all cost inputs should be entered in Australian dollars after applying the exchange rate required for the import declaration or planning scenario."
