    },
    {
      "q": "Should freight and insurance be included?",
      "a": "Many destinations use CIF-style planning where freight and insurance affect the dutiable base, but valuation rules vary. Enter 0 if the destination or quote does not include them in the base."
    },
    {
      "q": "What is the de minimis field?",
      "a": "The optional threshold lets you model low-value treatment by suppressing estimated duty and VAT/GST when the dutiable base is at or below the threshold."
    },
    {
      "q": "Does MPF apply everywhere?",
      "a": "No. MPF is a U.S.-specific term. For non-U.S. shipments, use that field only for an equivalent customs processing or entry fee."

      "q": "How is this different from a landed cost calculator?",
      "a": "This tool focuses on customs, tax, and clearance line items. Use the landed cost calculator when you also need origin, destination, inland delivery, and unit-cost planning."
