TRA proposes new countervailing duties on USA HVO biodiesel
The TRA has proposed a countervailing measure on USA HVO biodiesel imports and has terminated its parallel dumping investigation.
The Trade Remedies Authority (TRA) has published its Statement of Essential Facts on imports of hydrotreated vegetable oil (HVO) biodiesel from the United States of America.
The investigation, launched on 17 March 2025, covers HVO biodiesel—also known as renewable or green diesel.
Following evidence that subsidised imports are causing material injury to UK biodiesel producers, the TRA’s Statement of Essential Facts sets out its intended final recommendation for a fixed duty measure, with proposed countervailing duties of between £257.80 and £303.56 per tonne.
Interested parties are invited to comment on the initial findings via the Trade Remedies Service by 19 December 2025.
Separately, the TRA has terminated its parallel investigation into dumped imports of HVO biodiesel from the USA due to a lack of significant evidence of dumping.

The investigation, launched on 17 March 2025, covers HVO biodiesel—also known as renewable or green diesel.
-
Hydrotreated vegetable oil (HVO) biodiesel is a renewable fuel that can replace mineral diesel.
-
The product covered in the investigations includes: biodiesel (or paraffinic diesel fuel / gasoil) obtained from synthesis or hydrotreatment of oils and fats of non-fossil origin, in pure form or as included in a blend, originating in the United States of America (US). This biodiesel is commonly known as hydrotreated (hydrogenated) vegetable oil diesel (HVO), renewable diesel or green diesel. Synthetic paraffinic kerosene (also known as sustainable aviation fuel (SAF)) is excluded from this description of biodiesel.

Countervailing duties are one of three trade remedy tools used to address goods that are being unfairly subsidised by overseas governments and causing injury to UK industry.
-
Termination of investigation – the TRA will propose terminating a dumping or subsidy investigation if, at any stage during the investigation, we find that the dumping margin or subsidy amount for all relevant goods (cumulatively and per country) is below de minimis levels. We will publish a notice to explain why the investigation has been terminated and notify the Secretary of State and interested parties accordingly.
-
Following the verification and analysis of exporter data the TRA has determined that all three US exporters that took part in the case presented a negative dumping margin. Therefore, there was no significant evidence of dumping by US exporters Diamond Green Diesel LLC, St Bernard Renewables LLC, and Phillips 66.
