  "faq": [
    {
      "q": "What does a DDP shipping cost include?",
      "a": "A DDP quote normally includes freight, import duty, import tax, customs brokerage, destination handling, final delivery, and the seller or forwarder risk margin."
    },
    {
      "q": "Who pays duty under DDP?",
      "a": "The seller is responsible for import duty and tax under DDP, although the contract and local importer-of-record rules must be checked carefully."
    },
    {
      "q": "Why add a risk buffer to DDP?",
      "a": "DDP sellers carry exposure to duty changes, customs exams, storage, delivery exceptions, and underquoted destination fees. A buffer makes the quote more realistic."
    },
    {
      "q": "Is DDP the same as landed cost?",
      "a": "No. DDP is a commercial delivery term where the seller pays through delivery. Landed cost is the buyer-side total cost model and can be used for FOB, EXW, CIF, DAP, or DDP comparisons."
    },
    {
      "q": "Does this replace a customs duty calculator?",
      "a": "No. This tool uses simple duty and tax percentages inside a DDP quote. Use a customs-duty calculator or broker for HTS classification, MPF, HMF, Section 301, AD/CVD, and entry details."
    },
    {
      "q": "Can DDP be risky for US imports?",
      "a": "Yes. Importer-of-record, customs valuation, Section 301 tariffs, and broker control can create compliance risk if the DDP provider is vague about how entry is handled."
