}Calculate US import duty and landed cost estimates. Give hts_code when you know it and this returns the calculated base duty and trade actions (Section 301, Section 232, Section 338, AD/CVD and others), estimated duty, fees and import cost. When estimate_status is partial, AD/CVD is undetermined and the amounts are provisional; convey that the estimate is incomplete. Give product instead and it returns candidate HTS codes WITHOUT pricing, because the classification decides the duty and guessing it produces confidently wrong numbers: confirm the right code with the user, then call again with hts_code. The candidate step is not charged.
| Argument | Type | Description |
|---|---|---|
| product | string | Plain description, e.g. "outdoor metal furniture". Returns candidate codes to confirm, does not price. Provide this OR hts_code. |
| hts_code | string | Exact HTS rate line, 8 or 10 digits, e.g. "9403.20.00.50". Takes precedence over product. 4 and 6 digit headings cannot be priced. |
| entry_date | string | Optional: the date the goods will be entered, YYYY-MM-DD (US Eastern time), today or later. Default today. |
| country_code* | string | ISO 2-letter country of ORIGIN (where the goods were made), e.g. "CN", "CA", "VN". |
| shipment_mode | string | Optional: "ocean" (default) or "air". Affects government fees only. |
| declared_value* | number | Customs value of the shipment in USD. |
