• usitc_browse_chapter Browses the web · ~329 tokens
  Browse numbered headings with complete distinct eight-digit rate-line relationships and independent ten-digit statistical counts. A unique combined ten-digit source row can establish an absent eight-digit relationship. Published subchapter titles group following headings when present. Chapters 98 an
• usitc_check_additional_duties ~537 tokens
  Find Chapter 99 candidate headings and source references for an exact eight- or ten-digit commodity number. Coverage is partial and empty candidates never establish clearance. Use candidates, evidence with a returned candidateCode, or unmapped views; follow returned noteId and noteCursor for complet
• usitc_get_heading ~357 tokens
  Inspect a four-, six- or eight-digit HTS classification and its complete indented descendants, including unnamed superior rows. Published section titles are retained separately in sections, outside legal ancestry. Ancestry is built from the whole containing heading before filtering. Each parent and

  List accepted identifier formats, edition-pinned Special Program Indicators, chapter/section navigation labels, quantity units or published release metadata.

  Retrieve an eight-digit rate line or exact ten-digit statistical number with all published General, Special and Column 2 cells.

• usitc_search_hts ~288 tokens
  Search published USITC descriptions or complete HTS code prefixes in source order. Matches are flat published rows with unresolved rates; call usitc_get_heading for legal ancestry and usitc_lookup_duty_rate for exact base rate columns.
