  "faq": [
    {
      "q": "How do I calculate density for Dayton Freight?",
      "a": "Measure the packed handling unit in inches, calculate cubic feet, then divide total pounds by cubic feet. This gives lb/ft3 for density-based LTL planning."
    },
    {
      "q": "Is this an official Dayton Freight calculator?",
      "a": "No. This is an independent planning calculator. Dayton Freight, your broker, or the applicable NMFC item can assign a different official class."
    },
    {
      "q": "What dimensions should I enter?",
      "a": "Enter the outer dimensions Dayton Freight would receive: full pallet, crate, or carton size including pallet deck, stretch wrap, top cap, and overhang."
    },
    {
      "q": "Can density alone determine freight class?",
      "a": "Not always. Density is important, but commodity, stowability, handling, liability, packaging, and carrier tariff rules can override the density class."
    },
    {
      "q": "Why does this matter for importers?",
      "a": "Many cross-border sellers use US LTL after ocean or air import. Density helps estimate the domestic leg from warehouse, 3PL, prep center, or port-area facility."
