Use BEFORE asking a China supplier for a final quote or before paying, when you need the minimum data/compliance checklist for China → US or China → EU low-regulation physical goods. 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.
Required origin country; use China/CN/PRC for this v1 corridor.
Required destination country or EU; use United States or an EU member state.
Optional material and intended use, such as textile or consumer gift item. Supply when known to improve risk screening.
Optional plain-language physical-good description. Omit only if unknown; product-specific requirements then remain incomplete.

}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.
| Argument | Type | Description |
|---|---|---|
| quotes* | array | Required array of 2–5 raw supplier quote objects or preflight_quote_passport outputs. Keep corridor, currency, quantity, unit price, and shipping fields comparable; missing or mixed values are reported rather than guessed. |

}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.
| Argument | Type | Description |
|---|---|---|
| hs_code | string | Optional supplier- or broker-provided HS/HTS/CN code. Omit if unavailable; no classification is fabricated. |
| currency | string | Currency for a numeric unit_price. Omit only when unit_price is an object carrying currency; otherwise the passport marks currency missing. |
| incoterm | string | Optional stated Incoterms rule, for example EXW, FOB, DAP, or DDP. Omit only when absent from the quote; it will be listed as missing. |
| quantity* | integer | Required positive number of units covered by the supplier quote. |
| lead_time | string | Optional supplier production/transit lead-time text, such as 15 days. Omit when not stated. |
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.
| Argument | Type | Description |
|---|---|---|
| hs_code | string | Optional supplier- or broker-provided HS/HTS/CN code. Omit if not already available; this tool never fabricates or independently validates classification and will request manual review. |
| incoterm | string | Optional three-letter Incoterms rule such as EXW, FOB, DAP, or DDP. Supply it when stated on the quote; omit only when unknown and expect a missing-field flag. |
| quantity* | integer | Required positive number of physical units; use the supplier quote quantity, not cartons unless each carton is the priced unit. |
| unit_value* | any | Required non-negative per-unit goods value. Pass a number with unit_value_currency, or an object containing amount/value and currency. |
| unit_price* | any | Required non-negative per-unit supplier price. Pass a number with currency, or an object containing amount/value and currency. |
| material_use | string | Optional material and intended-use context. Supply it when known to improve restricted-category screening. |
| shipping_cost | any | Optional quoted freight/shipping amount. Omit when the supplier did not state it; hidden_or_unknown_costs will flag the gap. |
| origin_country* | string | Required country of shipment origin; this v1 is for China/CN/PRC. |
| quote_valid_until | string | Optional supplier validity date or text, preferably YYYY-MM-DD. Omit when the quote has no stated expiry. |
| shipping_currency | string | Currency for a numeric shipping_cost. Omit when shipping_cost is an object carrying currency or is absent. |
| destination_country* | string | Required destination country or EU; this v1 supports United States and EU member states. |
| product_description | string | Optional plain-language physical-good description; strongly recommended before payment and needed for a useful product-risk screen. |
