The U.K. government announced on Tuesday that the Secretary of State has accepted the Trade Remedies Authority’s (TRA) final recommendation to impose new anti-dumping duties on biodiesel imported from China. The TRA concluded that Chinese biodiesel had been sold in the U.K. at unfairly low prices, causing material injury to domestic producers such as Argent Energy and Olleco.

After reviewing all submitted evidence and responses to its Statement of Essential Facts, the TRA confirmed that enforcing anti-dumping measures is in the U.K.’s economic interest. According to the authority, the duties are necessary to restore fair competition, protect local manufacturers, and maintain integrity in the renewable fuel market at a time when demand for low-carbon fuels continues to grow.

The recommended measures take the form of ad-valorem duties. Shipments from Greenergy and cooperating non-sampled exporters will face a tariff rate of 14.79%, while all other exporters will be subject to a significantly higher duty of 54.64%.

These duties apply to biodiesel imports including fatty acid mono-alkyl esters (FAME) and paraffinic diesel derived from non-fossil sources such as HVO, whether imported as pure products or in blends. However, sustainable aviation fuel (SAF)—either pure or blended—is explicitly excluded from the scope of the measure.

The decision signals the U.K.’s firm stance on countering unfair trade practices and ensuring a level playing field for its renewable fuel industry, while balancing domestic economic interests and environmental goals.
