Tariff Code Compliance

Return the native profile and exact guide for a tariff system, optionally selecting a version instead of the active runtime version.

describe_tariff_system

Read saved, prepared CBP Customs Bulletin text independently of search. Pass the search result issue_path, research as_of and version on the first call. For every continuation keep those three fields unchanged and set only page_token to the exact token returned by the preceding page. Reports preparing, failed or explicitly stale evidence; never downloads or parses PDFs during the request.

get_customs_bulletin_document

Fetch one native tariff node by its opaque node_id.

get_node

List filtered native incoming and outgoing edges for an opaque node_id.

list_node_edges

List enabled tariff systems and the explicit versions available for native graph traversal.

list_tariff_systems

Resolve native tariff nodes by source key, one or more typed identifiers, and optional version, kind, and effective-time filters.

resolve_nodes

Search prepared CBP Customs Bulletin evidence with required publication dates, normalized phrase or all-term matching, and exact ruling identifiers. The response echoes the supplied tool_input, reports the selected immutable index_scope and concrete unavailable_sources once, and may return useful results despite source gaps. Follow every page while has_more is true, including empty intermediate pages, by repeating the original input with next_page_token as page_token. A mention or empty results array is not a legal-status determination.

search_customs_bulletins

Find conceptually related passages in a prepared CBP Customs Bulletin snapshot. The response echoes the supplied tool_input and shares the lexical result and coverage contract, including selected immutable index_scope and concrete unavailable_sources. Global searches return at most one passage per issue for diversity; an exact issue path may return several. Supports optional inclusive publication dates, returns 1-20 top passages with raw cosine similarity and exact locators, has no pagination, and never falls back to lexical search. Similarity or empty results is not a legal-status determination.

semantic_search_customs_bulletins

Search the exact selected US HTS build with SQLite full-text search across provisions, headings, ancestor context, and indexed notes. Optionally restrict before ranking with scope={type:general_note|gri|chapter,number:string}; use number:"*" with general_note or chapter to search that complete note family, and combine chapter:* with kinds=["note"] for all chapter and section notes. Scope intersects with kinds. Results retain stable graph node IDs and official evidence locators for graph navigation. Use semantic_search_hts separately for conceptual discovery.

search_hts

Find conceptually related provisions and notes in the exact selected US HTS build using text-embedding-3-large and S3 Vectors. Optionally restrict before ranking with scope={type:general_note|gri|chapter,number:string}; use number:"*" with general_note or chapter to search that complete note family, and combine chapter:* with kinds=["note"] for all chapter and section notes. Scope intersects with kinds. Results are hydrated from the matching SQLite artifact and retain stable graph node IDs and evidence locators; semantic similarity does not replace legal analysis or graph navigation.
