Notes
  Product scopes are read from the tariff-barrier model behind Global Trade Alert's
  US tariff estimates, at the policy date for each action: 26 July 2026 for the two
  proposed Section 301 actions and 3 June 2026 for Section 122. Import values are
  2024 US customs values (USITC, HS 8-digit). The two Section 301 actions are
  proposals open for comment, not duties in force; the figures size what they would
  reach and are not forecasts. All-origin value measures the economic footprint of a
  product list; for the Brazil-specific lines Brazilian-origin trade is reported,
  because all-origin value there is dominated by goods Brazil exports little of.
