Line-by-line mapping of additional tariff actions carried in HTS Chapter 99: for each 8-digit HTS code, the active action programme, the origin country it bites on, the Chapter 99 heading that imposes it, the additional rate in percent and the U.S. note that supplies the legal basis. Built by parsing the Chapter 99 annexes of the HTS export, so the mapping is reproducible against the published schedule.

Fields

Column names are the CSV header; the array-typed columns join their members with | in the flat file.

Column	Type	Description
`hts8`	string	8-digit HTS code the action applies to.
`action`	string	Action programme slug: section_301_china or section_232_russia.
`country`	string	Origin country the action bites on.
`basis_note`	string	U.S. note cited by the Chapter 99 heading as the legal basis (e.g. 'U.S. note 20(s)').
`action_heading`	string	Chapter 99 heading that imposes the additional duty (e.g. 9903.88.01).
`rate_pct`	number	Additional ad valorem rate in percent, as stated by the heading; null when the heading carries no single unambiguous percent.
`effective_date`	empty	Effective date when the annex states one; null here because the Chapter 99 enumeration this extract parses does not carry per-line dates.
`end_date`	empty	End date when the annex states one; see effective_date for why this extract leaves it null.
`source_url`	string	Exact USITC file the record was parsed from.
`retrieved_at`	string	UTC timestamp of the source retrieval.
