• usitc_search_hts

  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. Follow nextCursor with identical arguments…
