check_import_claim
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.
Eingabeschema
{'type': 'object', 'required': ['claim'], 'properties': {'claim': {'type': 'string', 'description': "The claim in the user's words, e.g. 'under $800 is duty free'"}}}
classification_rulings
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assigned — including any chapter 99 heading, which is what carries a Section 301 addition — and whether the ruling has been revoked or modified.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.
Eingabeschema
{'type': 'object', 'required': ['query'], 'properties': {'limit': {'type': 'number', 'description': 'How many rulings to return, 1–10 (default 5)'}, 'query': {'type': 'string', 'description': "The product in ordinary words, e.g. 'LED face mask', 'plush toy', 'power bank'"}}}
duty_passport
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.
Eingabeschema
{'type': 'object', 'properties': {'pick': {'type': 'string', 'description': "Product slug, e.g. 'pet-fountain'; omit with query to list all slugs"}, 'query': {'type': 'string', 'description': 'Keyword matched against slug and HTS description'}}}
duty_stack_rules
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.
Eingabeschema
{'type': 'object', 'properties': {'part': {'enum': ['all', 'rules', 'fees', 'superseded'], 'type': 'string', 'description': 'Which part to return; default all'}}}
import_rule_changes
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.
Eingabeschema
{'type': 'object', 'properties': {'limit': {'type': 'number', 'description': 'Maximum documents to return (default 25)'}, 'since': {'type': 'string', 'description': 'Only documents published on or after this date (YYYY-MM-DD)'}, 'matched_in': {'enum': ['title_or_abstract', 'full_text_only', 'any'], 'type': 'string', 'description': 'title_or_abstract = the import phrase is in the headline matter (usually the ones that matter); default any'}}}
landed_cost
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.
Eingabeschema
{'type': 'object', 'required': ['goods_value_usd', 'hts_base_rate_pct'], 'properties': {'ocean_entry': {'type': 'boolean', 'description': 'True for ocean entries, which add the Harbor Maintenance Fee; default false'}, 'goods_value_usd': {'type': 'number', 'description': 'Customs value of the goods in USD'}, 'section_232_pct': {'type': 'number', 'description': 'Section 232 addition in percent; default 0'}, 'section_301_pct': {'type': 'number', 'description': 'USTR Section 301 addition in percent (0 / 7.5 / 25 / 50 / 100); default 0'}, 'hts_base_rate_pct': {'type': 'number', 'description': "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': {'type': 'number', 'description': 'Freight plus insurance in USD; default 0'}}}
recall_check
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.
Eingabeschema
{'type': 'object', 'properties': {'pick': {'type': 'string', 'description': "Product slug, e.g. 'cable-powerbank'"}, 'query': {'type': 'string', 'description': 'Keyword matched against the tracked categories and recall titles'}, 'only_hits': {'type': 'boolean', 'description': 'Only categories with at least one recall; default true when no pick/query given'}}}
section_301_ladder
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.
Eingabeschema
{'type': 'object', 'properties': {'note': {'enum': ['20', '31'], 'type': 'string', 'description': '20 = the original Section 301 lists; 31 = the increases effective 2024-09-27'}, 'heading': {'type': 'string', 'description': "A chapter 99 heading prefix, e.g. '9903.88.03' or '9903.91'"}, 'rate_pct': {'type': 'number', 'description': 'Only headings carrying this additional rate, e.g. 25'}}}
