Use normalize_supplier_quote when you already have one quote, compare_preflight_quotes for 2–5 quotes, and trade_preflight for shipment-level cost/rule screening. Do not use it as a tariff classifier, freight marketplace, customs broker, or legal adviser. Output includes required_fields, recommended_fields, manual_review_flags, product_risk_flags, authoritative_sources, and status. UNKNOWN means the corridor or a requirement cannot be established; NEEDS_MORE_DATA means more inputs are needed; MANUAL_REVIEW means a human must review the product or entry. - `compare_preflight_quotes`: Use BEFORE choosing or paying a supplier to compare 2–5 China supplier quotes for the same China → US or China → EU purchase. Each item may be a raw quote accepted by normalize_supplier_quote or an existing preflight_quote_passport. Use normalize_supplier_quote first when you have only one quote, and trade_preflight for a shipment-level gate. Do not use it as a freight-rate marketplace, tariff classifier, customs brokerage service, or legal advice. Output includes comparable, comparison_basis, rows, ranking, excluded_from_comparison, and message. UNKNOWN means goods-plus-shipping cannot be computed; NEEDS_MORE_DATA means inputs are incomplete; MANUAL_REVIEW means a human must resolve a product/compliance flag. A ranking is never an all-in landed-cost winner. - `normalize_supplier_quote`: Use BEFORE accepting or paying one China supplier quote. Turn the quote into a comparable preflight_quote_passport, preserve Incoterm and validity context, and expose missing landed-cost fields and hidden/unknown costs. Use compare_preflight_quotes for 2–5 quotes and trade_preflight for a shipment-level gate. Do not use it as a live freight quote, HTS/TARIC classifier, customs brokerage service, or legal advice. Output includes quote, preflight, missing_quote_fields, hidden_or_unknown_costs, ready_for_comparison, and disclaimer. UNKNOWN means a cost or field is not supplied; NEEDS_MORE_DATA means the passport cannot support a reliable comparison; MANUAL_REVIEW means a human must decide. - `trade_preflight`: Use BEFORE accepting or paying a China supplier quote for one China → US or China → EU shipment. This shipment-level gate exposes missing landed-cost inputs, dated low-value rule changes, and compliance blockers for low-regulation physical goods. Use normalize_supplier_quote for one quote, compare_preflight_quotes for 2–5 quotes, and check_trade_requirements for a checklist. Do not use it as a freight-rate marketplace, HTS/TARIC classifier, customs brokerage service, or legal advice. Output includes status, corridor, missing_fields, dated authoritative_sources, estimated_landed_cost_components, de_minimis_low_value_treatment, compliance_flags, human_review_reason, and disclaimer. UNKNOWN means a cost or rule cannot be established from supplied inputs; NEEDS_MORE_DATA means required values are missing; MANUAL_REVIEW means a human importer, broker, or compliance reviewer must decide.
