Fact-check a circulating claim about US import duties against the dated official record. Returns a verdict, why, and the sources. Covers the four figures still repeated everywhere in 2026: the $800 de minimis exemption, the $80–$200 postal flat duty, the ~54%/$100 courier rule, and 'reciprocal' baseline tariffs. Use this when a user quotes a number for US imports.
The claim in the user's words, e.g. 'under $800 is duty free'

}Search CBP's own binding classification rulings (CROSS) for a product in plain words and get what CBP actually decided: ruling number, date, subject, the HTS codes it assigned — including any chapter 99 heading, which is what carries a Section 301 addition — and whether the ruling has been revoked or modified. This is precedent from the agency that decides, not a guess: it is how you check whether the code your supplier gave you matches what CBP has ruled on comparable goods. Queried live at call time from rulings.cbp.gov; nothing is mirrored here.
| Argument | Type | Description |
|---|---|---|
| limit | number | How many rulings to return, 1–10 (default 5) |
| query* | string | The product in ordinary words, e.g. 'LED face mask', 'plush toy', 'power bank' |

}Candidate HTS headings for a consumer product category, pulled daily from the official USITC HTS REST API: the candidate line, its general rate, every rated line in the heading, and the Section 301 status to verify on USTR. These are candidates chosen by category reading, not a classification ruling — the importer of record classifies.
| Argument | Type | Description |
|---|---|---|
| pick | string | Product slug, e.g. 'pet-fountain'; omit with query to list all slugs |
| query | string | Keyword matched against slug and HTS description |

}The current China→US import duty stack, rule by rule, each with the record that establishes it and the date it was decided or published: HTS base rate, Section 301, Section 232, the struck-down IEEPA tariffs (2026-02-20), the indefinite de minimis suspension (2026-06-24), the expired postal flat rate (2026-02-28), and the MPF/HMF fee rates. Use this before quoting any US import rule from memory — the 2025 guidance that dominates training data is superseded.
| Argument | Type | Description |
|---|---|---|
| part | string | Which part to return; default all |

}What changed in the general US import rules, newest first, from the official Federal Register API: presidential tariff actions, CBP and DHS rules, USTR notices — each with its publication date, document number and federalregister.gov link. Use `since` to get only what is new to you, the same way you would poll a changelog. Case-specific antidumping, ITC and Foreign-Trade Zone paperwork is out of scope by design and the response says so.
| Argument | Type | Description |
|---|---|---|
| limit | number | Maximum documents to return (default 25) |
| since | string | Only documents published on or after this date (YYYY-MM-DD) |
| matched_in | string | title_or_abstract = the import phrase is in the headline matter (usually the ones that matter); default any |

}Itemise a US landed cost from rates you supply: duties (HTS base + Section 301 + Section 232 on the customs value), MPF 0.3464% with the CBP floor disclosed, HMF 0.125% on ocean entries, plus freight and insurance. Deterministic arithmetic with the assumptions and sources attached. This tool never invents a product's duty rate: omit hts_base_rate_pct and it refuses and points you at the official schedule.
| Argument | Type | Description |
|---|---|---|
| ocean_entry | boolean | True for ocean entries, which add the Harbor Maintenance Fee; default false |
| goods_value_usd* | number | Customs value of the goods in USD |
| section_232_pct | number | Section 232 addition in percent; default 0 |
| section_301_pct | number | USTR Section 301 addition in percent (0 / 7.5 / 25 / 50 / 100); default 0 |
| hts_base_rate_pct* | number | The heading's general rate of duty, in percent. Look it up at hts.usitc.gov or with duty_passport; this server will not guess it. |
| freight_insurance_usd | number | Freight plus insurance in USD; default 0 |

}Official US product recalls (CPSC saferproducts.gov API) touching a product category in the last 365 days: date, title, hazard and the cpsc.gov URL. A keyword hit means the words appear in a recall title, not that a particular supplier or SKU is affected. Use before recommending or sourcing a category.
| Argument | Type | Description |
|---|---|---|
| pick | string | Product slug, e.g. 'cable-powerbank' |
| query | string | Keyword matched against the tracked categories and recall titles |
| only_hits | boolean | Only categories with at least one recall; default true when no pick/query given |

}The Section 301 (China) additional-duty ladder, read straight from the official USITC HTS export of chapter 99 subchapter III: which 9903.88 / 9903.91 heading carries which addition (7.5%, 10%, 15%, 25%, 50%, 100%), which U.S. note defines its list, and — where the schedule states it — the date that heading took effect. It tells you the possible rates and where coverage is defined; it never asserts that a particular HTS8 code is on a list, because that lives in U.S. note 20/31 and the USTR annexes.
| Argument | Type | Description |
|---|---|---|
| note | string | 20 = the original Section 301 lists; 31 = the increases effective 2024-09-27 |
| heading | string | A chapter 99 heading prefix, e.g. '9903.88.03' or '9903.91' |
| rate_pct | number | Only headings carrying this additional rate, e.g. 25 |
