A significant set of anti-dumping duties on US-origin biofuels expired today, 12 September, removing the measures from 39 commodity lines. The action, which affects products across the mineral fuels, fats, and oils chapters, follows directly from the administrative adjustments to the measures' validity periods that were reported yesterday. Today's update contained no other policy changes.

The themes

Today's update was defined by a single, significant action: the scheduled conclusion of a major trade defence case. The ending of anti-dumping duties on US biofuels represents the final step in a process that began with administrative updates on 11 September, bringing a focused end to a long-standing set of protective measures. The entirety of the day's 156 recorded changes related to this single event.

Headline items

The sole development today was the ending of anti-dumping duties on a range of biofuel products from the United States.

  • Action: Anti-dumping measures ended, effective 12 September 2026.
  • Origin: United States.
  • Products: The measures covered 39 commodity lines for various biofuel blends and components, primarily fatty-acid mono-alkyl esters and paraffinic gasoils, classified under HS chapters 15 (Fats and oils), 27 (Mineral fuels), and 38 (Miscellaneous chemical products).

Coming into force

All 156 changes loaded in the tariff update took effect today, 12 September. These were comprised of the 78 measure endings for the US biofuel duties and 78 associated footnote removals. No future-dated measures were introduced.

What to watch

The expiry of these long-standing anti-dumping duties on US biofuels marks a material change in the import conditions for this segment of the energy market. Following several days of related administrative activity, the focus now turns to the market impact of this liberalisation.
